Toronto and Region Conservation Authority (TRCA), in partnership with the City of Toronto, has proposed to undertake remedial slope stabilization works in the rear yards and valleylands behind privately-owned residential properties along Ridge Point Crescent, City of Toronto, to provide long-term, low maintenance protection to at-risk essential structures.
Project Location
The project area is located in a TRCA and City of Toronto owned valley corridor southeast of the intersection of Lawrence Avenue West and Black Creek Drive. Black Creek is located within the valley behind Ridge Point Crescent.

Project Background
Slope stability issues behind 19 – 31 Ridge Point Crescent were first reported to TRCA by residents after the July 8, 2013 severe storm event, which resulted in massive flooding and damage to river and valley systems across the Greater Toronto Area. Ongoing erosion and slope instability has created a risk to City of Toronto infrastructure, privately owned property, and overall public safety.
Based on the visual assessment of the site completed by Terraprobe Inc. in 2013, TRCA retained Cole Engineering Group Ltd to conduct a detailed slope stability and erosion risk assessment in 2015. The findings of the assessment identified that there is long-term risk of additional slope failure and that remedial works are recommended to provide long-term protection.
In order to address this risk, TRCA initiated the Ridge Point Crescent Slope Stabilization Project (the “Project”) to provide long-term, low maintenance protection to at-risk essential structures adjacent to and within the Project area.
In 2018, TRCA initiated a Class Environmental Assessment (Class EA), planned in accordance with Conservation Ontario’s Class Environmental Assessment for Remedial Flood and Erosion Control Projects (as amended 2013), the approved process for this type of undertaking. A Notice of Intent initiating the project was published in the North York Mirror on February 8, 2018.
In accordance with the Class EA process, the first point of public contact occurred with the publication of the NOI in the North York Mirror on February 8, 2018. Notices were sent to Aboriginal groups, community groups, homeowners in the vicinity of the project site, and government regulatory agencies including Conservation Ontario (CO), the Ministry of Environment and Climate Change (MOECC), and the City of Toronto. The NOI requested that individuals contact the Project Manager if they wish to participate further in the EA process or be kept informed about the Project’s status.
TRCA hosted a Community Liaison Committee (CLC) meeting on November 14, 2018 for interested stakeholders to present the findings of the geotechnical investigation and preferred alternative solutions to provide long-term protection for 19 – 31 Ridge Point Crescent, in the City of Toronto.
Evaluation of remedial slope treatment alternatives led to the identification of Alternative 4: Vertical Solution as the preferred alternative for the Ridge Point Crescent Slope Stabilization Project. TRCA retained a geotechnical engineering consultant in June 2018 through a competitive Request for Proposals to prepare detailed designs for the preferred treatment alternative.
TRCA issued a Notice of Filing and filed a Project Plan on December 19, 2019. Following a 30-day public review period a Notice of Project Approval was issued on February 14, 2020.
Scope of Work
The objective of this project is to protect at-risk participating privately-owned properties along Ridge Point Crescent, City of Toronto, from valley slope instability and erosion hazards. Through 2022, TRCA intends to:
- Finalize detailed designs for the chosen remedial slope treatment(s)
- Secure necessary permits, approvals, and agreements for construction
Construction Information
TRCA is currently in the planning stages for the Project. Construction is tentatively scheduled for 2023, pending receipt of all necessary permits and approvals, finalizing detailed designs, and to the limit of available annual funding.
Construction information showing work area, access areas, trail closures, alternative routes, tentative schedule and highlights will be updated once the project commences.
