Palace Pier Court Headland Maintenance Project

Toronto and Region Conservation Authority (TRCA), in partnership with the City of Toronto, is undertaking maintenance works on an existing shoreline erosion control structure along Lake Ontario, within Humber Bay Shores Park, in order to protect against the hazards of shoreline erosion and address public safety concerns.

Project Location

The project area is located at the base of Palace Pier Court, near Humber Bay Shores Park along the north shore of Lake Ontario, in the City of Toronto. The area of concern includes an armourstone revetment and a gravel trail located along the shoreline.

Project Background

The armourstone headland and adjacent gravel trail were heavily damaged as a result of the April 14-15, 2018 wind storm event.

During this storm event, high winds and waves caused the movement of stone material that was protecting the shoreline, and washed out most of the gravel trail.

Following this storm, structure conditions have continued to worsen due to ice buildup during the winter months and record high Lake Ontario water levels in 2019.

In 2019, TRCA retained GHD Limited to develop detailed designs for repair of the headland and trail in order to address ongoing erosion concerns and restore the trail to a state of good repair.

The design includes reconstructing the shoreline armouring, using both original and new rock material, and rebuilding the gravel trail, which will be protected by the new structure.

Scope of Work

The scope of work for the project includes the long-term repair of the armourstone revetment and gravel trail to protect the shoreline and mitigate erosion concerns. The following will be completed in achieving this goal:

  • Developing detailed designs for repair of the revetment and gravel trail
  • Obtaining all required permits and approvals
  • Site preparation, including installation of access roads, staging and stockpiling areas, sediment and erosion control measures, and construction fencing
  • Repair of revetment and gravel trail
  • Site restoration, including tree and shrub planting

Construction Information

Construction details will be provided once implementation begins.

Public Notices

Notice of Construction signs will be placed at applicable park entrances and affected trail routes. Notice of Project Commencement letters will be circulated to members of the local community prior to construction.

Project Updates

Update: June 17, 2019
This project is in the early planning stages. GHD Limited, a coastal engineering consultant, has been retained to develop conceptual and detailed designs for the long-term repair of the armourstone revetment and gravel trail.

Update: December 5, 2019
Detailed designs are being finalized and required permits and approvals are being secured. The final stages of the planning process are underway.
