Toronto and Region Conservation Authority (TRCA), in partnership with the City of Toronto, has proposed to undertake erosion control and slope stabilization works to provide long-term protection for a City of Toronto maintenance yard located at 30 Northline Road, in the City of Toronto.
The project area is located adjacent to 30 Northline Road, south of Eglinton Avenue West, atop a steep valley slope along the northeast side of the East Don River. The area of concern is the south-eastern extent of the City of Toronto maintenance yard adjacent to 30 Northline Road.

Erosion issues have been a concern at 30 Northline Road for some time, especially since the July 8, 2013 severe storm event, which resulted in massive flooding and damage to river and valley systems across the Greater Toronto Area (Figure 2). Ongoing erosion and slope instability has created a risk to City of Toronto works yard buildings located at the top of the slope, the Metrolinx railway bridge abutment at the slope toe of western edge of the project area, and overall public safety.
In 2014, TRCA retained Sarafinchin Associates to conduct a detailed slope stability and erosion risk assessment of the property, which determined that ongoing erosion and slope instability has created a risk to three one-story brick buildings at the top of the slope.
In 2015, 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 and East York Mirror on October 29, 2015.
TRCA subsequently retained Terraprobe Inc. to propose a range of alternatives to provide long-term, low maintenance protection for the essential infrastructre identified to be at risk. A Community Liaison Committe (CLC) meeting was scheduled in Summer 2017 to present the preferred alternative solution to interested stakeholders. Unfortunately the meeting was cancelled due to an absence of confirmed attendees.
Next steps include:
- Preparation and filing the Class EA Project Plan for the 30 day review period;
- Finalizing detailed designs of the preferred alternative(s);
- Obtaining all necessary permits and approvals to proceed to construction; and
- Commencement of construction works including access road and staging/stockpiling tentatively in winter 2019, pending receipt of necessary permits and approvals
TRCA is currently in the planning stages of this work, including reviewing preliminary designs and obtaining necessary regulatory permits and approvals. Implementation of works is not scheduled at this time.
In accordance with the Class EA process (Figure 5), the first point of public contact occurred with the publication of the NOI in the North York Mirror and East York Mirror on October 29, 2015. 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 coordinator if they wish to participate further in the EA process or be kept informed about the Project’s status.
