SERVING COMMUNITIES, SAFEGUARDING FUTURES:
TRCA 2024 Annual Report
LAND ACKNOWLEDGEMENT
We respectfully acknowledge the lands we are situated on are Traditional Territories and Treaty Lands, in particular those of the Mississaugas of the Credit, as well as the Anishinaabe of the Williams Treaty First Nations, the Huron-Wendat, the Haudenosaunee, and are now home to many diverse First Nations, Inuit and Métis peoples. Toronto and Region Conservation Authority (TRCA) appreciates and respects the history and diversity of the land and is grateful to have the opportunity to work and meet in this territory.
TRCA’S VISION, MISSION, AND CORE VALUES
VISION
The achievement of safe and resilient communities.
MISSION
The provincial leader in conserving, restoring and managing natural resources to advance safe and sustainable development.
CORE VALUES
Working with government and the communities we serve to achieve collective impact and advance shared goals.
• Integrity • Collaboration • Accountability • Respect • Excellence •
Toronto and Region Conservation Authority’s (TRCA) 2024 Annual Report highlights the many ways TRCA is serving its communities and safeguarding the futures of the people, businesses, and other stakeholders across TRCA’s jurisdiction.
TRCA’s talented and dedicated staff continued to drive progress on goals through a combination of science, advocacy, and action needed to make a difference in this region.
The storm events of July 16 and August 17-18 offered a stark reminder of the power of nature and the critical importance of TRCA’s mission to protect our communities from the increasingly severe effects of extreme weather, including flooding, erosion, and other natural hazards.
In response to these recent events, we have strengthened our commitment to safeguarding our communities through robust flood warning systems, resilient natural hazard mitigation infrastructure, and programs designed to build and enhance sustainable, climate-ready communities.
Sustainable communities also require greenspaces for a variety of reasons. TRCA’s jurisdiction includes some of the fastest growing municipalities in Canada, with a population of over five million living within its managed watersheds. With 81.3% or 4.1M people in our jurisdiction living within 2 km of TRCA owned and managed public land, and 81% of TRCA lands offering public access, TRCA’s greenspaces play a vital role, not only ecologically, but also in providing recreation, respite, and public enjoyment.
The lands TRCA has acquired and managed since its inception represent an important combination of environmental hazard protection right alongside health and wellbeing benefits.
This year, TRCA leveraged our historic landholdings to support the expansion of the Rouge National Urban Park and the Uxbridge Urban Provincial Park ensuring their long-term protection and management.
This year marks 70 years since Hurricane Hazel impacted our region, and recent climate change-fueled storms are reminders of TRCA’s safeguarding role.
TRCA recognizes the importance of informed decision-making across its business areas. When municipalities, residents, and businesses have access to up-to-date information on flood risk and mitigation strategies, they are better able to safeguard themselves and their properties. Similarly, when communities are engaged in knowledge-sharing on the impacts of climate change, they can actively participate in the development of strategies and collective action to build future climate resilience.
This year’s report highlights advancements on several significant projects, including significant shoreline restoration initiatives on Lake Ontario, including Jim Tovey Lakeview Conservation Area and Ashbridges Bay, as well as improvements to the Lake Ontario Waterfront Trail across TRCA’s jurisdiction, which have included significant aquatic and terrestrial habitat improvements.
This report showcases vital infrastructure protection work in valleys, including at E.T. Seton and Beverley Acres parks, and climate change proofing projects that will shape the health of tomorrow’s communities, like the re-naturalization of the Lower Don River and the Toronto Island Park Flood and Erosion Mitigation Project, among others.
None of TRCA’s work would be possible without the support of our communities, partners, and stakeholders. TRCA extends its gratitude to all who contribute to its mission of serving communities and safeguarding the future across its jurisdiction.
Sincerely,

Paul Ainslie
Chair, TRCA Board of Directors

EXPLORE THE 2024 ANNUAL REPORT
Toronto and Region Conservation Authority’s (TRCA) 2024 Annual Report is organized around four strategic pillars, reflecting the structure of our 2023-2034 Strategic Plan. Select the pillars below and the numbered performance measurements associated with each to view TRCA’s progress towards its goals in 2024.
GOAL: Mitigating hazard risks to communities and protecting the natural environment
Flood Risk Management
This year, the Greater Toronto Area (GTA) region experienced record setting precipitation and temperatures, alongside an unprecedented frequency of extreme weather events, including torrential downpours that led to significant flooding. While extraordinary, these can no longer be considered isolated events.
Flooding at Queen Frederica Drive, Mississauga – July 16, 2024
The year’s weather has prompted TRCA to re-examine its approach to flood mitigation and emergency response.
TRCA’s industry-leading Flood Forecasting and Warning Program already exceeds provincial requirements by providing effective and reliable emergency communications. However, efforts are underway to further increase its reach and impact, ensuring that residents receive timely alerts to take informed action to safeguard themselves and their properties against extreme weather events, including potential flooding.
As always, TRCA is committed to exceeding expectations to enhance public awareness and enable informed decision-making by its stakeholders.
In 2025, TRCA will work closely with municipal partners to implement updated and robust emergency plans and procedures that address the growing frequency of unprecedented and unpredictable extreme weather events.
Efforts will focus on reaching a broader segment of the public and ensuring that property owners are prepared to make informed decisions to protect themselves from the effects of flooding events.
By expanding flood warning systems and enhancing public education, TRCA and its partners aim to further reduce the impacts of flood events in 2025. These measures will equip residents, businesses, and stakeholders to respond effectively to extreme weather events.

1.1 |
Deliver provincially mandated services pertaining to natural hazards including flood and erosion |
TRCA provides provincially mandated services pertaining to natural hazards including flood and erosion monitoring and risk management.
Inspections and Warnings: Key Highlights



Ashbridges Bay Advancements
The creation of Toronto’s newest waterfront lands advanced significantly in 2024. A collaboration between TRCA and the City of Toronto, the Ashbridges Bay Treatment Plant Landform Project provides a land base for the City’s wet weather flow treatment facility expansion, while also addressing longstanding shoreline erosion issues and sedimentation challenges that impact safe navigation.
Initiated in 2013, the project provides shoreline protection, improves water quality, and supports water treatment infrastructure. Additionally, it enhances aquatic habitats and creates new publicly accessible natural spaces, including trail connections to Tommy Thompson Park.
In 2024, several key milestones were achieved, including the completion of the final headland, 3 cobble shorelines, maintenance roads, construction of a shoreline naturalization area, installation of aquatic plantings, construction of aquatic habitat shoals, and topsoil placement.
Construction on the Central Breakwater is expected to be substantially completed by the end of 2024.
Additionally, a public drop-in session engaged community members on the restoration and trail plans for the new public natural areas.
Flood Infrastructure
TRCA operates and maintains 12 dams, 6 dikes, and 9 channels. 11 dams have current safety reviews, and all dams have current operation, maintenance, and surveillance manuals. All 7 of the high or very high hazard dams have current emergency preparedness and response plans.

Reducing Flood Risk
The removal of vegetation and sediment operations along 3.2 km of TRCA’s channels maximized the flow of water to reduce the risk of flooding. 88% of flood control channels have optimal conveyance to ensure the effective flow of water.
During the high volume, short duration storms experienced this summer, regular maintenance represented a critical need. To address this need, ongoing work at Mimico Channel and other sites is scheduled for completion in 2025.
Erosion Risk Management
Work this year has included 3.76 linear km of valley and shoreline stabilization at 31 priority sites. 87.5% of erosion control structures are in acceptable condition throughout the jurisdiction.
Flood Early Warning System
TRCA’s flood forecasting and warning program got a big boost through the implementation of the Deltares Flood Early Warning System (FEWS) in June 2023.
In 2024, the first full year of its implementation, this modern tool was used by TRCA Flood Duty Officers to provide high resolution gridded weather forecast data that is geographically accurate to TRCA’s watersheds. The system uses computational power to process forecasted rainfall data and calculate runoff estimations.
Leaving behind manual data entry from various sources, automated efficiencies unlocked resources for improved decision-making and timely flood messages to municipal partners and the public.
Future phases of the system implementation include incorporating hydrologic models and integrating telemetry data from surrounding areas within the GTA to further enhance situational awareness and responsiveness.
Broadview and Eastern Flood Protection Project Update
The Eastern Avenue Bridge demolition has been completed ahead of schedule. Detailed design work is 90% complete, with anticipated completion in early 2025.
TRCA continues to support the City of Toronto and the Province through technical permit reviews. This includes work on the future East Harbour Development and major transit investment to enable safe and sustainable communities in the City of Toronto.
Flood Risk Knowledge
30 rain gauges, 25 monthly-inspected stream gauges, and, with a new location added in 2024, 11 locations now have video coverage, enabling a continuous flow of timely data.


TRCA rain gauges
Hydrologic modelling is current for 100% of the jurisdiction supported by 333 flood line maps, which are shared with jurisdictional stakeholders.
Flood Communications
TRCA effectively informed key agencies, including Metrolinx, Mississauga Emergency Services, Toronto Emergency Management, and Toronto Transportation Services on anticipated localized flood risks.
The timely transfer of knowledge enabled successful externally-driven decisions during the summer’s critical storms to evacuate buildings, adjust Metrolinx bus and train operations, and close affected roads, minimizing impacts and better safeguarding people and property.

Flood Risk Warning Workshops: Advancing Knowledge, Training, and Province-Wide Excellence
In February, TRCA hosted the annual municipally-focused Flood Risk Workshop. 80 attendees representing all partner municipalities came together to ensure emergency preparedness.
In October, with Conservation Ontario, TRCA co-hosted the Provincial Flood Forecasting and Warning Workshop organized by the Provincial Flood Forecasting and Warning Committee (PFFWC). This annual event brings together agencies responsible for flood forecasting and warning, emergency management, flow measurement, and data collection, as well as other partners, to address policy and implementation needs and issues and to facilitate training.

Safe Slope at Kilgour Road
TRCA partnered with the Holland Bloorview Kids Rehabilitation Hospital to address an imminent risk to public lands and privately-owned infrastructure at Kilgour Road. Acting swiftly under an Emergency Works Declaration, TRCA revitalized the slope to ensure the safety of the surrounding community.
The project involved expert assessment, expedited permits and approvals, and oversight of the design-build contract, delivering results on time and within budget. Key improvements included the installation of 40 m of stormwater pipes, new access points, and a stable outlet to Burke Brook, reinforced with 9K m3 of stone for walls and bank protection.
3.4K trees and shrubs were planted to restore and beautify the ravine adjacent to the hospital property. This greenery not only enhances the landscape but also protects staff, patients, and visitors from erosion hazards.
Funding for this initiative was secured by the hospital under the Province of Ontario’s Health Infrastructure Renewal Fund. Close collaboration with the City of Toronto on overlapping City initiatives unlocked additional benefits, including stream rehabilitation, trail improvement, and sewer protection enhancements.

Leadership in greenspace conservation |
TRCA protects and manages natural heritage systems throughout its jurisdiction by ensuring safe operation and access, site protection and maintenance, ecosystem protection, and unmatched visitor experiences.
Input and Collaboration Advances Conservation Area Strategy
As the GTA’s largest landowner, with a wide breadth of land types and uses, TRCA engaged stakeholders this year to advance the Conservation Area Strategy.
The consultation process included municipal partners, First Nations communities and Indigenous peoples, the Regional Watershed Alliance, and the Building Industry and Land Development Association (BILD) Working Group. Public input, gathered through online surveys, also played a key role in shaping the strategy.
This collaborative approach ensures all partners are informed and engaged, empowering TRCA to lead in the protection and enhancement of critical conservation areas and greenspaces.
TRCA Lands, Greenspace Leadership
Management partnerships, primarily with municipalities, enable the efficient prioritization of environmental protection, hazard management, and community prosperity. A total of 5.1K ha or 32% of TRCA’s landholdings are managed by others.
Additionally, TRCA manages 719 ha of land owned by others when such arrangements benefit both parties and advance conservation efforts. TRCA has agreements with the Province of Ontario (Infrastructure Ontario) and the Ontario Heritage Trust.
Growing Ontario’s Greenspaces in Partnership
To protect greenspaces from large-scale growth and development pressures, TRCA conveyed 1,546 ha of land to the Ministry of Environment, Conservation and Parks (MECP), nearly tripling the size of Ontario’s newest year-round day use provincial park: Uxbridge Urban Provincial Park (UUPP).
The Partners Network played a key role in identifying the park’s full recreational and protection potential. Their input helped to shape the development of a management plan for the existing park properties and identified connections to TRCA programs and services.
TRCA facilitated consensus on the appropriate lands for the park through discussions with many stakeholders including MECP, Parks Canada, the Regional Municipality of Durham, and the Township of Uxbridge. The engagement process also prioritized youth involvement by collaborating with the Environment Specialist High School Major Program at Uxbridge Secondary School to ensure the perspectives of future generations were included in the planning process.
Right Lands, Right Place
The Greenlands Acquisition Project is a strategic initiative guiding the acquisition of land to advance environmental conservation and green infrastructure needs. Each year, dynamic partnerships and innovative mechanisms drive new opportunities and adaptations.
In 2024, TRCA acquired 43.9 ha across 12 parcels, including a 32.8 ha parcel in Vaughan.
Contributions to Rouge National Urban Park Expansion
Rouge National Urban Park, Canada’s first urban park, serves as an innovative model for future sustainability.
In the last decade alone, TRCA has collaborated with farmers, municipalities, schools, volunteers, Indigenous partners, and Parks Canada to safeguard the ecological integrity of this gem at Toronto’s doorstep.
137 individual projects have restored more than 200 ha of wetland, forest, and meadow habitats through the planting of more than 300K trees and shrubs.
Collaboration continues to drive significant results. In 2024, TRCA announced the future transfer of 119 ha to Parks Canada for inclusion in this federal park.
Additionally, a federal investment of $950K was secured to enhance habitat quality and improve landscape connectivity within the Rouge River and West Duffins Creek watersheds. These long-term restoration efforts provide vital nature-based solutions to reduce carbon emissions, mitigate flooding, and address future climate change challenges.
Managing Newly Established Meadows
Meadows are part of grassland ecosystems, relying on periodic “disturbances” to maintain and encourage the growth of native grasses and wildflowers.
2024 marks the second year of advancing TRCA’s in-house expertise using fire management as a leading-edge restoration technique. 2 successful and separate controlled burns occurred at meadow restoration sites at Albion Hills this year, with benefits to species at risk.
Foundational Forests
From the long-standing 24-year partnership with York Region to more recent ones with NGOs like Trees for Life, TRCA and partners are improving the resilience and ecological function of the landscape:
- 83K trees and shrubs planted in York Region, including through 13 private landowner projects and the Grow Your Legacy program.
- 89K trees and shrubs planted in Durham Region, through initiatives such as the Durham 5 TREES partnership, which is modeled after York Region’s successful approach. Celebrating a 3rd planting season in 2024, this program is administrated through co-ordinated efforts across 5 conservation authorities, supported by a diverse range of funding sources. This collaboration enables significant restoration efforts and underscores the power of partnership-driven environmental action.


Wonderful Wetlands
TRCA, in collaboration with the Town of Ajax, is restoring wetlands in the Carruthers Creek watershed through MECP’s Wetland Conservation Partner Program. As part of this initiative, 12K trees and shrubs will be planted, expanding wetlands by 3 ha.
This upcoming work is part of a larger 6 ha wetland and 1.5 ha forest initiative in Durham, which last year saw the completion of the Kerrison wetland restoration project and includes ongoing invasives management work.
The restoration work is being achieved through a partnership with Ducks Unlimited and the Town of Ajax, combining multiple sources of funding to maximize outcomes.
The City of Brampton’s Ecopark Strategy advanced significantly with the completion of Jefferson, Jordan, and Jayfield Parks in 2023, Eastbourne Park in 2024, and plans to restore Fallingdale Park in 2025.
At Eastbourne Park, natural channel design was implemented to address erosion, increase flood resilience, and improve aquatic and riverside habitat. Restoration efforts included 900 m of stream restoration, the planting of 8.4K trees and shrubs, and the installation of 8K live stakes.
As part of these efforts, a fall event through TRCA’s Sustainable Neighbourhoods Action Program (SNAP) engaged 80 local residents and volunteers to plant 350 native trees and shrubs, forming Brampton’s first Tiny Forest.
Beyond the City of Brampton’s commitment to advancing these important urban initiatives, this work was further facilitated thanks to support by ECCC Nature Smart Climate Solutions Fund via a Conservation Ontario umbrella project.
Restoration at Albion Hills
Restoration efforts progressed on a newly acquired 36 ha parcel of land land at Albion Hills, strategically positioned to enhance connectivity and ecological resilience.
This year’s efforts resulted in the restoration of 1.9 ha of wetlands, 6.4 ha of forest, and 12.5 ha of meadows, achieved through an integrated site-wide focus.
TRCA’s hallmark restoration strategy combines funding and resources from various mechanisms, including compensation agreements, municipal contributions, grants, and private donations, ensuring maximum impact.
Enhancing Caledon’s ecological landscape at Albion Hills is a forward-looking investment given the anticipated pressures of the future, including wet weather years along with increased impermeability from development in downstream areas.
The wetlands, forests, and meadows are now better connected and on track to full restoration; in return the abundant “gifts” of water absorption and retention, clean air and water, and habitat opportunities for numerous species at risk are just a few of the listed benefits.
The trails and recreational amenities that meander through the Albion Hills restoration sites also encourage visitors from near and far to marvel at nature’s beauty and bounty up close, restoring our human connections to our land in the process.

Maintain healthy and resilient watershed ecosystems in the face of a changing climate |
TRCA implements effective, targeted programs that improve watershed health and resilience through ongoing monitoring and assessment of natural resources within its jurisdiction.
Restoration Key Highlights
TRCA Implemented 376 restoration, resource management and stewardship projects across the jurisdiction:






Timing Matters for Restoration Evaluation
Successful restoration takes time, which is why monitoring and follow-up are essential components of a multi-year process.
In 2024, nearly half of the 80 restoration sites assessed were evaluated after just one year – the most critical and high-risk phase. Of these, 56% required minimal maintenance, while the remaining sites necessitated additional follow-up. These locations will be reassessed during years three and five to ensure progress and address any challenges.
Years with lower than anticipated restoration trajectories are opportunities to examine contributing factors, including severe weather and climate-change impacts, that influence the ability of natural environments to regenerate and provide restorative benefits.
Watershed Plan Updates
The 2024-2034 Etobicoke Creek Watershed Plan was fully approved and endorsed by all partner municipalities.
This collaborative effort also included guidance by the Mississaugas of the Credit First Nation, additional First Nations and Indigenous communities, the Greater Toronto Airports Authority, residents, watershed stakeholders, and members of the public.
The plan and associated 62 datasets will guide various TRCA and municipal initiatives, such as land use and infrastructure planning, ecosystem restoration, and climate adaptation. Next steps include the formation of an Implementation Steering Committee to initiate action.
Progress on the Humber River Watershed Plan advanced this year with the completion of the Future Scenario Analysis by technical experts.
A total of 9 Technical Scenario Analysis Reports were produced by TRCA subject matter experts and consolidated into a Future Scenario Analysis Report for the watershed plan with guidance from the Steering Committee. There were 3 partnerships with academic institutions and scientific programs to advance assessments of water quality, erosion risk, and groundwater.
A total of 57 datasets were prepared during this process to inform decision-making internally and by partner municipalities.
Preparations are underway to launch the Rouge River Watershed Plan in 2025, while implementation tracking for the Carruthers Creek Watershed Plan continued this year.
Celebrating 60 Years of the Provincial Water Quality Monitoring Network
Since 2002, TRCA has been collecting water quality samples from 13 locations across its jurisdiction as part of the Provincial Water Quality Monitoring Network (PWQMN).
These sites complement an additional 34 locations that TRCA collects as part of the Regional Watershed Monitoring Program (RWMP), for a total of 47 locations.
TRCA’s collaboration with the Province ensures that this work contributes to a comprehensive provincial dataset, supporting water quality improvements across Ontario.
With six decades of data collection, the PWQMN highlights TRCA’s ongoing commitment to safeguarding water quality and advancing a cleaner, healthier environment.

Protecting Biodiversity
Invasive species are the second biggest driver of biodiversity loss worldwide, and left unchecked can significantly harm ecological function and climate change resilience.
With support from Peel Region, in 2024 TRCA completed its third year of invasive plant management at three major Conservation Parks in Peel: Heart Lake, Albion Hills, and Claireville.
Efforts have focused on management of woody invasive species such as European buckthorn and invasive honeysuckles along trails (which act as pathways for invasive species spread). Targeted plant species such as Phragmites and invasive thistles were also managed at restoration sites.
Approximately 75 ha of invasive plants were managed in TRCA’s Peel parks last year, improving the ability of forests, meadows, and wetlands to support biodiversity and withstand climate change stressors.
Yellow Creek’s Collaborative Gains
Yellow Creek, a tributary of the Don River in midtown Toronto, benefited from TRCA’s Erosion Valley Hazards work, which serves multiple agency objectives, while protecting private residential properties through slope-supportive channel stabilization works.
Additionally, collaboration with the City of Toronto ensures the protection of critical infrastructure, including watermains and storm outfalls. These efforts were supported by geomorphic and hydraulic analyses to guide effective solutions.
Stabilizing the watercourse at this location creates a further opportunity for the City of Toronto to advance trail planning work to improve trail and greenspace access, resulting in significant community wellbeing benefits.


Coordinated Commitment for Waterfront Restoration
Since 2006, Aquatic Habitat Toronto (AHT) has been instrumental in shaping the Toronto waterfront through its consensus-based partnership building. Coordinated by TRCA, AHT encompasses agencies across multiple jurisdictional boundaries and spans three levels of government.
This working group has become a model for innovative research, monitoring, and habitat restoration planning. By following and implementing the recommendations of the Toronto Waterfront Aquatic Habitat Restoration Strategy (TWAHRS) over the past 15+ years, AHT has achieved significant outcomes, such as the work at Gibraltar Point, Tommy Thompson Park, and the new mouth of the Don River.
In 2024, a half-day event at the revitalized Port Lands celebrated AHT’s collaborative efforts. Participants included representatives from Fisheries and Oceans Canada, Ontario’s Ministry of Natural Resources, TRCA, Waterfront Toronto, Environment and Climate Change Canada, PortsToronto, and the City of Toronto.
The event highlighted AHT’s collective achievements, and each agency had the opportunity to share their contributions to the development of the Toronto Waterfront, with a particular focus on the Port Lands Flood Protection Project (PLFPP), which served as the event location.
Regional Watershed Monitoring Program
Annual sampling ensures robust datasets to inform planning and provide insights for data-backed decisions across TRCA’s initiatives.
Highlights from 2024 monitoring activities include:
- 47 water quality sites sampled monthly, including 13 Provincial Water Quality Monitoring Network (PWQMN) sites.
- 132 benthic invertebrate samples collected across TRCA’s jurisdiction.
- Completion of the 8th set of fish community data collected, with 49 fish community samples in Carruthers Creek, Duffins Creek, and the Rouge River.
- Continuous stream flow data at 36 sites and baseflow measurements at 126 sites.
- West Nile Virus Mosquito Larvae Monitoring Program sampling at 46 sites.
- Water level at 21 groundwater wells monitored quarterly as part of the Provincial Groundwater Monitoring Network (PGMN), 13 wells also sampled for water quality.
- Terrestrial regional monitoring data collected at 143 locations, including at 24 forest plots, 23 wetland plots, 29 forest bird sites, 24 wetland bird sites, 20 meadow bird sites and 23 frog sites.
Etobicoke Creek Wetlands Enhancement Project
Loafer’s Lake, a high-priority restoration site with significant water quality challenges, experienced transformative improvements in 2024 thanks to collaborative efforts and key stakeholder involvement.
The Heart Lake Turtle Troopers raised awareness about shoreline restoration needs, which sparked momentum among decision-makers. Guided by TRCA’s expertise in design, funding, implementation, and outreach, the City of Brampton successfully completed a comprehensive restoration of the site.
A $2.5M grant from Ontario’s Wetlands Conservation Partner Program funded the restoration of four sites within the Etobicoke Creek Watershed. The project restored 5 ha, planted 6.5K trees and shrubs, removed 1 ha of invasive species, and added turtle habitat features.
New amenities, including the realigned Etobicoke Creek Trail, bioswale, and scenic lookouts, enrich the community while supporting conservation goals such as improved water quality, flood mitigation, and ecosystem connectivity.
Community engagement played a vital role in the project’s success. Local residents continue to participate through volunteering and educational events, fostering a deeper appreciation for conservation efforts. Initiatives like this highlight the power of knowledge, partnerships, and collaboration in creating sustainable communities.

Balance development and growth to protect the natural environment ensuring safe sustainable development |
TRCA ensures safe and sustainable development throughout its jurisdiction to protect communities and the natural environment to minimize impacts to greenspace and infrastructure, ensure flood protection and remediation and maximize benefits for communities
The Business of Safeguarding Communities
TRCA’s Development Planning and Permits and Infrastructure Planning and Permits business units play a vital role in protecting life, property, and natural features. Through comprehensive planning policies and regulatory oversight, they ensure that new developments, redevelopments, and infrastructure projects are safeguarded against flooding and erosion risks.
In 2024, TRCA reviewed thousands of planning and infrastructure projects, and issued 1,280 permits. These efforts prevented or mitigated construction in flood or erosion-prone areas and ensured the proper protection of wetlands.
This proactive approach eliminates or reduces the risk of property damage and enhances public safety by mitigating the impacts of extreme weather events and changes to the watersheds.
In addition to protecting developed areas, TRCA plays a critical role in restoring and enhancing natural ecosystems. Through land use planning, TRCA’s planners integrate natural heritage restoration into urban development, ensuring that wetlands and river valleys are preserved or, where possible, rehabilitated.
These efforts not only contribute to flood mitigation by absorbing excess water but also support biodiversity and improve the resilience of the region’s natural landscapes. By balancing development with ecological stewardship, TRCA promotes sustainable growth while maintaining essential environmental protections.
Review Role
Among legislative, regulatory, and policy consultations, TRCA reviewed and commented on 51 municipal planning documents, 25 Environmental Registry of Ontario) postings, and 3 federal initiatives.
Through its implementation experience and scientific expertise, TRCA helped reconcile conflicts and achieve shared objectives for fulfilling TRCA’s mandated responsibilities and advocating to safeguard watersheds and watershed residents.
Enforcement and Compliance
TRCA plays an important role in valley and stream corridor management, regulating impacts of development and activities in hazardous land (such as floodplains, shorelines, or wetlands) under the Conservation Authorities Act (Conservation Authorities Act, R.S.O. 1990, c. C.27 | ontario.ca).
Scarborough Waterfront
TRCA, in partnership with the City of Toronto, continues to advance their vision for improving public access and connectivity along the Lake Ontario shoreline in Scarborough.
As part of the approved Scarborough Waterfront Project Environmental Assessment (Bluffer’s Park east to Highland Creek), detailed design of the West Segment is nearing completion. In addition, shoreline work is underway at Bluffers Park and construction of the Brimley Road South Multi-use Trail is set to begin in 2025.
For the shoreline from Bluffer’s Park to the Eastern Beaches (Silver Birch Avenue), TRCA launched a Comprehensive Environmental Assessment (EA) for the Scarborough Bluffs West Revitalization Study. The Study will explore opportunities for equitable public access to and along the waterfront, as well as opportunities to minimize erosion risk and enhance sensitive shoreline and natural areas.
Stakeholders, including the general public, agencies, Indigenous rights holders, and urban Indigenous communities, will continue to be consulted as the EA progresses in 2025.
Ajax Shoreline Erosion Mitigation Project
TRCA completed the Environmental Assessment for a 6 km stretch of Ajax’s shoreline, considering 12 sites through efficient prioritization. Supported by $1.6M in funding from the Canada Water Agency, the project will advance to final designs, permits, and remedial work over the next three years.
The first kilometre of shoreline will be protected with new cobble and boulder beaches. This action, paired with ongoing monitoring, sets the stage for addressing the remaining needs of this vital lakefront area.

Toronto Island Park Flood Mitigation: Environmental Assessment Complete
With a goal to permanently protect the park from shoreline flooding and erosion for the long-term, the Toronto Island Park Flood and Erosion Mitigation Project Class Environmental Assessment Environmental Study Report was completed this year.
Together with the City of Toronto, initiating design-related work in 2025 will advance the implementation of recommendations triggered by record-breaking lake water levels and flooding in 2019 that closed the park for three months.

Planning and Permit Applications, Project Permits, Ontario Lands Tribunal
- 1,280 permits issued, more than 85% of which met or exceeded minimum mandated timelines
- 790 planning and concept applications received
- 45 new Environmental Assessment and Planning Act applications received
- 25 Voluntary Project Review letters issued
By integrating and leveraging input from a team of professional technical experts, TRCA has effectively influenced numerous initiatives, including:
- Tracked 20 Ministerial Zoning Orders and completed major MZO implementation permit agreements.
- Involved in 30 Ontario Land Tribunal cases, 9 more than 2023, with 11 of those appeals settled or withdrawn following negotiations. In addition, 11 new appeals requiring TRCA participation were received in 2024.
- 655 Solicitor Realtor Inquiries were responded to, providing clients with timely information to support land-based decisions in the Toronto region.
Planned, Piloted: PARES Now Implemented
TRCA’s Planning Application and Enforcement System (PARES) program launched this year, enabling fully digital workflows following two years of collaborative preparations.
This year staff prepared extensively for the planned public launch in 2025, a change impacting more than 2K anticipated files.
This transformative, highly interactive, web-based platform is set to provide online services to TRCA’s residential, commercial and municipal customers through a citizen portal, enabling automation to advance application screening, technical review, and circulation to commenting stakeholders.
Modules with specific geographic and permit tracking functions allow for real-time monitoring resulting in maximized efficiencies, meeting and exceeding regulatory timelines and leading the first innovative system across Conservation Authorities in Ontario.
Don River – Waterfront
The largest flood protection and restoration public works project in Canadian history, the Port Lands Flood Protection and Enabling Infrastructure Project, reached a significant milestone this year: the Don River now flows directly into Lake Ontario for the first time in decades.
With the final “north plug” removed, the river now follows its restored path designed to protect surrounding neighbourhoods from flooding and create new natural spaces. This transformation includes new wetlands, floodplains, and a new island, paving the way for a future community and a vibrant, reimagined waterfront.

TRCA has proudly worked alongside community and Indigenous leaders, partners at Waterfront Toronto, and all levels of government on this transformational project, which has returned an important part of Toronto’s waterfront into a beautiful restored and more natural space, leaving a legacy that will serve the region for generations to come.
From Monitoring to Protective Implementation at E.T. Seton Park
Southwest of Don Mills and Eglinton is a section of the West Don River that flows through Ernest Thompson Seton Park. In 2020, monitoring through TRCA’s longstanding Valley Erosion Hazards Program revealed the need to address control structures for ongoing infrastructure, park and trail protection.
Instead of treating each of the 18 structures independently, TRCA pursued a comprehensive solution that considered the broader area’s needs.
Following a Class Environmental Assessment that included public consultation, this year implementation work continued to the second of three identified priority sites, with activities including channel realignment and grade controls. By collaborating with Toronto Water and ensuring the concurrent protection of their assets during the course of this project, both agencies benefitted greatly.
Work on the remaining site (Area 1) is scheduled for 2025. Upon completion, the park’s trail and river system will offer residents and visitors enhanced safety, aesthetic improvements, and protected infrastructure.
Beverley Acres German Mills Creek Erosion Control Project in Richmond Hill
This year, TRCA completed the Schedule B Municipal Class Environmental Assessment. The design phase for this project is anticipated for completion by end of 2025, with construction slated for 2026/2027. Funding of $1.8M through Canada’s Disaster Mitigation and Adaptation Fund is enabling this extensive project to protect infrastructure in Richmond Hill.
GOAL: Contributing to environmental targets through knowledge advancement
Supporting Action Through Sector Expertise
TRCA plays a pivotal role in helping municipalities integrate green infrastructure into their communities.
Initially focused on reacting to erosion and flooding, TRCA now addresses root causes by promoting proactive, evidence-based decision-making.
In cases of information gaps, direct research, at the appropriate scale, has been required. This has led TRCA to conduct in-depth studies to develop the insights required for implementation.
Watershed planning has been the most important mechanism to advance resource management to address flood and erosion risks and safeguard the region from natural hazards.
Proven, cost-effective solutions such as increasing permeable cover through low-impact development approaches (permeable pavements, rain gardens, urban forests, and meadows), help communities mitigate challenging wet-weather years, while enhancing ecological resilience.
TRCA also assists municipalities in maintaining and optimizing green infrastructure systems through informed asset management frameworks.
Natural assets like wetlands and riparian zones are inventoried, monitored, and effectively managed to maximize both environmental and economic benefits.
As climate science advances, TRCA continues to lead by implementing forward-looking projects and fostering collaborative research focused on actionable strategies.
These efforts ensure TRCA and its partners can protect communities against climate risks.
TRCA also advances green infrastructure through hands-on restoration projects, rehabilitating degraded areas with native vegetation, naturalized waterways, and erosion control techniques.

TRCA’s new Watershed Planning Hub.
Updated Strategies Meet Legislative Requirements
To ensure the strategic work of TRCA programs and plans is consolidated, documented, and matches the requirements of the Conservation Authorities Act, the following Strategies and Plans were reviewed this year: the Watershed Strategy, Conservation Area Land Strategy, Ice Management Plan, Land Inventory, Flood and Erosion Asset Management Plan, and Flood and Erosion Infrastructure Operational Plan.
The opportunity to consult externally on several of these reviews helped to deepen the collaboration with members of the public and key stakeholders to advance the goal of creating safe, climate-resilient communities.
Bisected Biodiversity
An estimated 1.2M wildlife mortalities occur annually on regional roads within TRCA’s jurisdiction. To address this, TRCA’s road ecology program works to reduce these impacts with road closures, fencing, crossings, and habitat creation.
Collaborating with partners such as York Region, Peel Region, the City of Toronto, the City of Brampton, the City of Richmond Hill, and King Township, TRCA works to protect endangered species such as salamanders and turtles. These efforts support their safe migration between wintering habitats and summer breeding and nesting grounds, ensuring the ongoing protection of local biodiversity.
Seasonal Salamander Crossing Protection
Together with York Region and the City of Richmond Hill, TRCA work supports the endangered Jefferson Salamander as they leave their summer breeding grounds and head to their winter habitat, crossing Stouffville Road in the process.
Intermittent overnight road closures on Stouffville Road between Bayview Avenue and Leslie Street were implemented during rainy October nights in 2024 to ensure their safe passage.
Species Feature
The presence of various species within a region can serve as critical indicators of environmental health. In 2024, two species made notable appearances, reflecting significant ecological milestones.
Torontonians celebrated the first bald eagle nest documented in the region in 100 years. Once on the brink of extinction, the bald eagle has only recently been removed from the list of species at risk. This historic moment signals a positive species recovery strategy in action, strengthened through TRCA’s restoration efforts to conserve and enhance desirable habitat.

Another remarkable discovery occurred during aquatic monitoring: a Spotted Gar, an endangered native fish species, was recorded for the first time in 30 years. Known for its long snout and spotted body, this ancient predator is unique in its ability to breathe air when surfacing. This discovery underscores the need to continue to monitor and understand the biodiversity of local lands and waters to make informed decisions.

The discovery of a regionally rare kettle bog vegetation community within the Oak Ridges Moraine adds to the region’s ecological richness. These acidic, nutrient-poor bogs support specialized species that thrive in harsh conditions, such as the pitcher plant and bog laurel, both Regional Species of Conservation Concern.


The Harvester, North America’s only carnivorous butterfly, adds a unique twist to local biodiversity: their caterpillars feed on native Woolly Aphids. The Harvester’s presence along the Etobicoke Creek Trail in Brampton is notable, especially since it is the only recorded sighting in this municipality outside of Heart Lake Conservation Park.
Regulated Area Map Tool

TRCA’s Regulated Area Search Tool empowers home and property owners to determine whether their property falls within a TRCA-regulated area. This feature continues to gain popularity, accounting for 40.7% of all Planning and Development webpage views, with 56K in 2024.

TRCA provides partner municipalities with industry-leading science.
Land to Lake Initiative
The Land to Lake Initiative envisions a future in which governments and resource managers along Western Lake Ontario (WLO) actively collaborate and take strategic, coordinated actions towards improving water quality and ecosystem health.
Since December 2022, TRCA has partnered with federal and provincial governments to lead the coordination of the WLO municipalities and conservation authorities to achieve this vision.
6 municipalities, 7 conservation authorities, and the federal and provincial governments have been actively involved as Advisory Committee members to chart the path forward for the L2L Initiative. In 2024, 2 Advisory Committee meetings were held.
In 2024, the L2L Initiative was successful in securing funding for its continuation for one more year through a Canada-Ontario Agreement grant.
1 workshop was organized to engage approximately 80 partners across the broader WLO basin. This workshop will advance coordinated actions in the watersheds to benefit Lake Ontario health and wellbeing of the communities that depend on it.
The following 3 projects were initiated in collaboration with WLO partners and federal and provincial governments to achieve the collective objectives of improving water quality and ecosystem health across watersheds and Lake Ontario:
Natural Asset Management
Credit Valley Conservation | Project leads: Kyle Vander Linden and Tatiana Koveshnikova, CVC
This course focuses on enhancing the capacity of municipalities and organizations to manage natural assets and the ecosystem services they provide. It covers topics such as natural infrastructure, measuring service levels, assessing the value of these services, and understanding life cycle costs for effective management and restoration. This course will be delivered in 2025 with funding from COA 2025-2026.
Updating and Reporting Tributary Nutrient Loads
Canada Water Agency | Project lead: Daniel Rokitnicki, CWA/ECCC
This project aims to compile and update phosphorus load data for tributaries and point sources in WLO to address information gaps and to fulfill commitments at various governmental levels. It represents a potential outcome of the L2L initiative, demonstrating the group’s capacity for coordination and collaboration on ecological and water quality measures. Additionally, the project will facilitate ongoing collaboration through regular reporting and monitoring of changes over time at both local and regional levels. This project was completed in 2024 through ECCC funds.
Brampton Water Quality Strategy: Catch Basin Inserts
City of Brampton | Project lead: Cassie Schembri, Brampton
The City of Brampton is addressing the lack of water quality treatment for stormwater in approximately 60% of its neighborhoods by planning a pilot project for large-scale implementation of catch basin inserts. With over 22,000 catch basins in underserved areas, the estimated cost for installation and maintenance over two years is over $29 million. The project’s goal is to reduce effective impervious surfaces to below 25% in each subwatershed, thereby improving aquatic habitat health. The City of Brampton will be working with L2L partners to look for funding opportunities to complement Brampton’s investment.
Natural Asset Management
TRCA and the Greenbelt Foundation co-hosted a webinar which provided an overview of the initial steps and existing resources for municipalities to begin planning for natural assets in their asset management plans.
Green Infrastructure Knowledge
The Region of Peel has partnered with TRCA and Credit Valley Conservation to complete a green natural infrastructure inventory and condition assessment.
This year, a dedicated field team re-inspected a selection of individual trees and tree and shrub clusters within the regional road rights-of-way. They captured detailed information on tree species, size, and health, as well as tracking invasive plants, pests, and tree diseases.
The collected data will play a crucial role in supporting regional asset management planning, and advancing forest monitoring and maintenance goals.
Stormwater Pond Inspection and Maintenance Training
Stormwater ponds, essential components of urban water management infrastructure, require consistent monitoring and maintenance to ensure optimal functionality.
Recognizing this need, TRCA conducted a series of coordinated training sessions, including two in-field classes and one virtual session. TRCA’s leadership in this area was further underscored by an invitation to provide inaugural training for Eastern Ontario audiences in Ottawa.
In total, 266 attendees representing 58 distinct municipalities and 10 conservation authorities benefited from this leadership. Representatives from the MECP, as well as funding support through a Canada-Ontario Agreement grant greatly assisted these efforts.
A new training hub webpage with nearly 500 unique users is also available, through TRCA’s Sustainable Technologies Evaluation Program (STEP), for on-demand learning and development.
Stormwater Treatment Technology at The Bentway
The Bentway, an initiative to reimagine the space beneath the Gardiner Expressway, exemplifies how urban infrastructure can be transformed to foster a healthier and more connected city.
Within the Bentway Staging Grounds, TRCA monitors stormwater treatment technologies designed to manage runoff from the Gardiner Expressway.
These technologies consist of planters designed with two chambers: the first to dissipate the energy of the water and capture/filter sediment and other debris; the second is the planter itself, filled with planting soil and herbaceous plants.
Monitoring consists of evaluating the effectiveness of the planters in improving water quality and reducing runoff, assessing the level of maintenance required, and providing insights into design improvements to promote enhanced system function.
The colourful exhibit is hard to miss and easily engages users to reflect on how water flows through our communities and what it takes to manage this resource effectively.


GOAL: Building communities that drive local action and improve wellbeing
Evolving for a New Era: Rebranding The Village



Community prosperity hinges on adapting to the challenges of the day as a way to future-proof against emerging risks.
In 2024, Black Creek Pioneer Village underwent a bold transformation, rebranding as The Village at Black Creek. This change reflects a commitment to more inclusive storytelling, broadening the narrative to recognize the diverse communities that have shaped this land, including the Indigenous peoples who have lived here for millennia.
The journey to this transformation began in 2017, guided by five First Nations and enriched through collaboration with Indigenous scholars, artists, elders, and community members. Their direction has been instrumental in “restorying” the site to move beyond its traditional focus on settlers of European descent.
Partnerships with diverse equity-deserving artists, scholars, and communities have enriched The Village’s narratives, enabling visitors to experience stories shared from many perspectives through authentic voices.
The rebrand introduced a new logo and visual language, complemented by updated signage, a refreshed website, and a staff guide to align internal and external communications.
These elements, alongside a new positioning strategy, ensure that The Village at Black Creek resonates with modern audiences while honouring its roots as a cherished living history museum.
As a “learning campus”, The Village has recently opened its doors to local businesses creating unique experiences ranging from ghost walks to concerts, and large-scale events to escape games.
Today, The Village offers something for everyone, from scenic grounds and hidden stories of real people to engaging creative programming.
This rebrand marks an important milestone in creating a space that is inclusive, reflective, and welcoming for all.
With the revitalization effort underway, the focus now shifts to building strategic partnerships that amplify awareness and boost attendance, shaping the next chapter in the story of The Village at Black Creek: a one-of-a-kind Toronto destination.

When deforestation, contamination, overfishing, and in-stream barriers affect native fish populations, fostering a new generation of conservationists needs to be part of the answer. This year, a cohort of students released 87 native salmon fry into Duffins Creek at Claremont Nature Centre in partnership with Ontario Fish and Wildlife – just one part of TRCA’s ongoing mission to restore native GTA fish populations through connections and foundational memories.
Regional Watershed Alliance
The Regional Watershed Alliance, a diverse advisory committee to TRCA’s Board of Directors, provided input on 12 initiatives in 2024, including Uxbridge Urban Provincial Park, the Youth Greenspace Employment Program, and the Spills Response Program.
Colleague and friend Michael White was commemorated with a tree planting event at Phyllis Rawlinson Park this year. Michael was a member of TRCA’s Regional Watershed Alliance, co-chair of the Task Force to Bring Back the Don, president of the Richmond Hill Naturalists, and a passionate environmental advocate who involved countless students and young people in tree planting and conservation.
GOAL: Customer service excellence for efficient service delivery to adapt to a changing environment
COR Certification Achieved
Central to TRCA’s ability to serve communities and safeguard collective futures is its unwavering commitment to safety.
In 2024, TRCA achieved the prestigious Certificate of Recognition (COR) Certification from the Infrastructure Health and Safety Association (IHSA). This national accreditation verifies TRCA’s successful implementation of a comprehensive Occupational Health and Safety Management System and highlights its adherence to the highest health and safety standards in Ontario and across Canada.
The COR certification process evaluates compliance with legislative requirements and best practices through rigorous document reviews, interviews, and site observations.
Maintaining this certification requires continuous diligence, including internal and external audits.
TRCA’s next internal audit is scheduled for 2025, followed by an external audit in 2027. These processes ensure that TRCA continues to meet and exceed the standards required to uphold certification.
This accomplishment underscores TRCA’s dedication to fostering a safe and secure workplace while meeting the expectations of public and private sector partners who recognize COR as a benchmark of safety excellence.
Achieving COR Certification reflects the collective efforts of TRCA’s Health and Safety team, the COR cross-divisional working group, and all employees who contributed to meeting these rigorous standards. It demonstrates leadership in promoting health and safety excellence throughout all operations.
With COR Certification in place, TRCA is well-positioned to protect communities and meet the challenges of the future.

4.1 |
A strong and skilled workforce |
TRCA’s workforce is its most important resource, and the organization will remain competitive in the employment market through its commitment to talent retention and investment.
Staff Engagement
- 81% of staff participated in the annual staff engagement survey, which is reflective of employees’ commitment to TRCA’s engagement journey.
- An increase of 30.9 points of the Net Promoter Score was achieved, which is an industry-leading metric used to help assess overall employee satisfaction. This shift is a substantial improvement and reflects the effects of implemented changes to enhance a positive work environment.
- All 15 priority areas targeted for engagement showed positive progress, increasing by 5-17%.
Ongoing Diversity, Equity and Inclusion Progress

- 96% of seasonal staff stated they would return for a future opportunity, signalling a successful recruitment strategy.
- 92% of seasonal staff are likely to refer a friend to apply for a seasonal role.

Supported Summer Jobs, Future Careers
TRCA was pleased to host six Members of Parliament on site visits to witness the positive impacts of the Government of Canada’s Canada Summer Jobs wage subsidy program. This vital funding supports TRCA’s capacity during its busiest months.
In 2024, 106 participants gained valuable learning and employment experiences across various fields in the Greater Toronto Area, underscoring TRCA’s commitment to nurturing future careers and fostering professional growth.

Committed Staff Celebrated
In September, TRCA recognized the contributions of 112 employees celebrating milestones ranging from five to 30 years of service at a ceremony held at The Village at Black Creek.
Additional staff appreciation events, such as the annual Pancake Breakfast and Summer BBQ, provided more opportunities for colleagues to connect and celebrate collective achievements.

Ravine Youth Team
Now in its 5th year, the Ravine Youth Team, initiated as a pilot program in partnership with the City of Toronto, continues to offer meaningful employment opportunities for post-secondary students and recent graduates in environmental studies.
Various TRCA divisions work collaboratively to offer post-secondary youth enrolled or recently graduated from environmental sector education programs paid employment in a summer contract position, as well as enhanced career building opportunities such as certifications, workshops, lunch and learn events, and panel discussions.

Provide and manage an efficient and adaptable organization |
TRCA enhances the sustainability of its business model for generations to come by strengthening relationships with our partner municipalities and securing long-term partner support.
Sustainable Head Office Construction
This year, TRCA completed the final touches on its new Administrative Head Office, which includes rain gardens, solar chimneys/waterwalls, preheat glazing assemblies, open loop geothermal HVAC, and solar thermal panel arrays.
The office, set to open in 2025, highlights TRCA’s leadership in sustainable urban construction and collaboration across sectors.
The award-winning mass timber building integrates unique technologies, underscoring TRCA’s commitment to protecting the Toronto bioregion while fostering partnerships and gaining valuable insights.
Nature is Priceless
247% revenue growth over 2023 marks TRCA’s second-highest grossing year to date from film revenues by hosting Peacock, Netflix, Sony Pictures, and others.
TRCA’s exceptional adaptability, operational efficiency, and experience working with the film industry allowed TRCA to turn opportunities into major successes following recent industry labour disruptions.
These filming partnerships are always executed using best practices to support program investments that continue to pay dividends. Look out for TRCA greenspaces on your big screen!
Grants: Key Highlights
New Asset Management Plan
Endorsement of TRCA’s first comprehensive Asset Management Plan occurred this year. The new Asset Management Plan in its accessible digital format ensures that users can now quickly glean insights on their portfolios and plan capital projects. Building Condition Assessments for The Village at Black Creek North Lands, a collection of 5 heritage buildings, were also completed, facilitating internal and external conversations to advance the protection of the historic buildings.
Employee Engagement for Conservation
TRCA’s Look After Where You Live program saw enthusiastic participation from 37 organizations spanning diverse sectors, including banking, manufacturing, food and beverage, and entertainment.
1.5K individuals laced up their boots at 19 locations and donned gloves to restore greenspaces by removing 1.7K kg of litter and invasive species, and planting 1.7K trees/shrubs and 1K flowers.
These actions do more than just beautify and take care of our natural spaces. Look After Where You Live offers a chance to connect with, learn about, and foster a deeper appreciation for the role of our natural world.
New Times, New Technology
TRCA embraced advanced technologies in 2024 to enhance its operations and improve decision-making.
- High accuracy global navigation satellite system (GNSS) receivers and a geospatial mapping application were deployed to collect inspection data for Erosion Risk Management work. The location and elevation accuracy of below 30 cm (in many cases 5-10 cm accuracy) means erosion hazards and erosion control asset deficiencies are being delineated almost exactly as they occur on site. Closing the gap on data inaccuracies results in improved decisions through reduced costs and improved forecasting.
- 30 new acoustic recorders were installed at long-term wetland monitoring stations, enabling TRCA to identify the calling periods of individual frog species, critical indicators of wetland health. These tools will also help assess climate change impacts, such as earlier-than-usual frog calls in spring.
- Drone technology assisted in creating photogrammetry and 3D modeling of the Tradesman Cottage site in Pickering, a first for the Archaeology team achieved through strong internal collaboration.
- The implementation of Electronic Fund Transfers for vendor payments increases speed, improves security, ensures a lighter environmental footprint and efficiency gains.
Supporting Projects, Regional Knowledge and a Respectful Reputation
TRCA licensed archaeologists conducted 44 assessments on 35 ha in support of legislated internal and partner project needs, respecting the rich heritage value of Anishnaabe, Haudenosaunee, and Huron-Wendat nations roots in our jurisdiction.

Responsive relationships and a trusted brand with a reputation for excellence |
TRCA builds on past successes to deepen existing relationships and reach new audiences.
Heart Lake Medicine Wheel Garden’s Ongoing Legacy
14 years ago TRCA embarked on a journey of honouring and reconciling with the region’s history in one simple way: by collaborating with Indigenous partners more deeply.
One such collaboration led to the development and implementation of a Medicine Wheel Garden at Heart Lake Conservation Park.
Designed collaboratively as a space to honour seasonal cycles, it features 30 species representing the four cardinal directions, sacred medicines, colours, animals, and cycles of life.
This sacred place provides an opportunity for reflection at events both large and small. In 2024, public and private groups gathered here to commemorate the children of residential schools.
The presence of this special garden serves as a reminder to all visitors of the connectivity and shared history of TRCA’s communities.
TRCA Youth Council: Tomorrow’s Leaders in Action Today
Tomorrow’s generation of change makers, TRCA’s Youth Council, grew to 665 members this year.
Building healthy communities through nature connection advanced with their leadership this year in hosting notable events including: TurtleFest at Heart Lake Conservation Park together with the Canadian Wildlife Federation and the Ontario Turtle Conservation Centre; the first in-person town hall with other youth organizations attending including York Region Youth Food Committee and the Toronto Environmental Youth Council; and presenting the youth perspective at the Oak Ridges Moraine Land Trust Annual General Meeting.
In addition, members participated in retreats, litter cleanups, plantings, volunteer efforts, and other activities that build capacity for a sustainable future.

Respected Reputation
Ontario Field Ornithologists
TRCA staff were awarded a Certificate of Appreciation from the Ontario Field Ornithologists “for designing, seeking expert opinion, and implementing a science-based plan to protect the first pair of nesting Bald Eagles in the City of Toronto amid the demand and desire for control of co-nesting Double-crested Cormorants”.
Canadian HR Awards
TRCA was nominated for two 2 Canadian HR Awards, an industry-wide recognition.
TRCA’s excellence and innovation in virtual and remote work programs and practices garnered a nomination for the Best Remote Work Strategy award.
TRCA was also recognized for the University Of Waterloo Award For Next-Generation Employment Innovation, which celebrates Human Resources teams that have implemented an innovative initiative in the last 12 months to provide employment opportunities for young people/graduates. With youth representing a large proportion of TRCA’s seasonal staff, this award nomination is a great honour!
High Line Symposium
A presentation at the October 10, 2024, High Line Symposium on The Meadoway in the “Cultivating Communities with Nature” session was made along with participation in a panel discussion (pictured below).
The bi-annual Symposium brings together Network members and supporters from across North America to share insights and best practices.
Valuable connections made during the event will support the development of The Meadoway’s corporate sponsorship program.
4.4 |
Transparent decision making and accountable results |
TRCA measures and evaluates performance to inform outcome-based decision making.
Annual Audit
The 2023 Audited Financial Statements were issued with an unqualified auditor’s report, demonstrating transparency and compliance with financial reporting standards.
Optimizing Processes and Procedures
Maintaining up-to-date policies ensures alignment with current laws and standards, mitigates risks, and supports continuous improvement.
This year, 67% of all corporate policies were reviewed, and 41 new and updated policies and guidelines were approved and went into effect. A total of 163 staff were trained in the internal meeting management platform eScribe for efficiency and transparency gains.
Accountability Through Information Sharing
Freedom of Information requests provide a vital tool for the public to access information held by organizations, ensuring openness and transparency in decision-making and activities.
In 2024, work was undertaken on 59 requests. 52 new requests were received and 23 were closed, signaling TRCA’s commitment to transparency, accountability, and trust-building.
Advancing Safe and Secure Properties
In addition to attending to repairs and maintenance requirements as they occur, 81% of planned and budgeted priority repairs or replacements were completed, ensuring property portfolio implementation needs advance each year through State of Good Repair capital plan execution.
Collaboration Pays Off
With support from the Federal Economic Development Agency for Southern Ontario’s Canada Community Revitalization Fund, TRCA was able to complete $7.3M in vital infrastructure repairs and replacements between 2022 and 2024, including paving work at 4 conservation parks and construction of new accessible restrooms, outdoor picnic shelters, wayfinding signage, and more across TRCA’s jurisdiction.

TRCA was awarded $750K through the MECP Wetlands Conservation Partner Program to restore and enhance wetland habitats across the Region of Peel, improving habitat for native species and enhancing local flood resilience.
TRCA also collaborated with its partner municipalities, including the City of Brampton and the Town of Ajax, to complete wetland restoration and enhancement projects, which were supported with over $3M in funding from the Wetlands Conservation Partner Program.
Green Fleet Transition
TRCA officially adopted a Fleet Decarbonization Policy in January of 2023. Since then, significant progress has been made toward decarbonization of TRCA fleet vehicles.
Notably, almost 44% of TRCA’s on-highway passenger vehicles and light-duty trucks are either fully electric, plug-in hybrid vehicles, or hybrid gas-electric vehicles. This includes 3 battery electric trucks, underscoring TRCA’s commitment to adopting advanced, sustainable transportation solutions.
Further progress was achieved with the purchase of battery electric zero-turn mowers for use in Conservation Parks, as well as the repowering of a solar pontoon boat at Lake St. George Field Centre with modern electrically powered outboard marine engines.
For diesel-powered vehicles that have not yet been replaced with electric alternatives, TRCA introduced renewable diesel in 2024, significantly reducing emissions during this transitional period.
25 charging stalls across various TRCA sites support Green Fleet transition as TRCA continues to right-size, hybridize, and electrify operations.
A Legacy of Circularity and Material Diversion
For decades, TRCA has embraced the principle of re-use in its restoration operations, a concept now widely recognized as circularity.
Effective resource management is essential not only for financial stewardship, but also for minimizing environmental impacts, particularly the emissions generated by the re-use, supply, and transportation of goods.
Materials like unwanted aggregates, root wads, root clusters, and boulders, often discarded by developers, play a critical role in 90% of TRCA’s restoration projects.
When used correctly, these materials provide vital habitat features in streams, wetlands, and terrestrial environments, sometimes becoming a signature element of TRCA’s restoration approach.
By reclaiming these materials from nearby development sites, TRCA restoration crews have reduced both costs and TRCA’s carbon footprint.
In 2024, TRCA also sourced soils from nearby municipal and private projects to advance numerous priorities, including works at Etobicoke Centennial Park, Ashbridges Bay Landform, and the future Jim Tovey Lakeview Conservation Area.
These outcomes demonstrate the economic and environmental benefits that arise from mutually beneficial partnerships between the conservation and construction/development sectors.
