Eldorado Court Erosion Control and Slope Stabilization Project

Toronto and Region Conservation Authority (TRCA), in partnership with the City of Toronto, is proposing to undertake remedial erosion control and slope stabilization works behind Eldorado Court to provide long-term protection to residential properties located at the top of slope.

Project Location

The Eldorado Court Erosion Control and Slope Stabilization Project is located in the City of Toronto, northeast of Keele Street and Sheppard Avenue West. TRCA’s study area encompassed multiple private residential properties that border Northwood Park along Eldorado Court, Grandravine Drive, and Ladyshot Crescent.

Project Background

TRCA was initially notified of erosion concerns behind multiple residential properties located on Eldorado Court following the July 8, 2013 severe storm event. Flooding and erosion caused by this storm event resulted in damage to hundreds of properties across the Greater Toronto Area.

TRCA’s Erosion Risk Management Program (ERMP) offers affected landowners assistance with remedial erosion control and slope stabilization works. Assistance is offered on a priority basis (based on the extent of risk to a property) and to the limit of available annual funding.

In 2015, TRCA completed a slope stability and erosion risk assessment for select properties along Eldorado Court that reported damage after the July 8, 2013 severe weather event. The purpose of this assessment was to characterize the extent of risk at affected properties and determine whether residential dwellings located at the top of slope were at long-term risk from the ongoing hazards of erosion and slope instability.

The results of the 2015 assessment identified multiple residential dwellings are at long-term risk. In 2019, following reports of additional erosion concerns near the 2015 study area, TRCA opted to expand the project’s study area and undertook an additional slope stability and erosion risk assessment to assess other properties located along Eldorado Court, Ladyshot Crescent, and Grandravine Drive that border Northwood Park and were not involved in the 2015 assessment.

The results of the 2019 assessment identified additional properties within the study area were also at long-term risk from long-term hazards of erosion and slope instability.

Based on the results from the 2015 and 2019 slope stability and erosion risk assessments, landowners whose properties are deemed to be at-risk have been offered assistance with erosion control and slope stabilization works through TRCA’s Erosion Risk Management Program.

Slope stabilization works will be designed to provide long-term, low maintenance protection to at-risk properties. Due to the limits of available annual funding and the separation between at-risk areas within the project site, implementation of remedial works will be phased with the highest risk area addressed first.

Scope of Work

TRCA completed the preliminary planning stage for this project in 2020 by identifying all erosion hazard areas and at-risk properties located within the project area. With the extent of risk at this site known, TRCA’s next steps include:

  1. Completing a baseline inventory of the project area
  2. Offering assistance with erosion control and slope stabilization works and securing participation from all landowners whose properties have been identified to be at long-term risk
  3. Evaluating a range of alternative solutions and identifying a preferred solution for erosion control and slope stabilization works
  4. Developing detailed designs of the preferred erosion control and slope stabilization solution for the primary risk area
  5. Securing necessary permits and approvals required to proceed to construction

The above planning initiatives will be undertaken over the course of 2021 – 2022.

Construction Information

TRCA is currently in the planning stages for this project and construction is not scheduled at this time. Following the development of detailed designs, this section will be updated with relevant construction information.

Public Consultation

TRCA engages with affected landowners and other interested stakeholders throughout various stages of the project life cycle to ensure that public input is provided to inform project planning initiatives. TRCA seeks public input when:

  • Explaining study results and next steps to proceed with design development activities
  • Evaluating conceptual alternative solutions to identify a preferred solution for long-term, low maintenance erosion control and slope stabilization remedial works. Public consultation is particularly important during this stage to ensure TRCA undertakes a comprehensive evaluation process.
  • Developing detailed designs to ensure that the design addresses all landowner and stakeholder concerns, including potential disturbances due to construction activities

When seeking public input, TRCA coordinates open public meetings or reaches out directly to affected landowners and stakeholders. Should you be interested in being added to the project’s interested stakeholder list and receiving updates about this project, please contact the Project Manager.

Current News


  • TRCA is currently consulting with affected landowners whose properties are identified to be at-risk to offer assistance with slope stabilization works and confirm their interest in participating in the project. Landowner participation will inform the extent of work limits for the project.
  • Following confirmation of landowner interest in the project, TRCA will commence developing detailed designs in conjunction with a Professional Engineer
