Palace Pier Court Headland Maintenance Project

Toronto and Region Conservation Authority (TRCA), in partnership with the City of Toronto, is undertaking the Palace Pier Court Headland Maintenance Project 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 Etobicoke, 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 during the April 14-15, 2018 windstorm event. High winds and strong waves caused shifting and displacement of armourstone material as well as washout of the adjacent gravel trail. Since this storm, site conditions have continued to deteriorate 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 shoreline to a state of good repair.

The design includes reconstructing the shoreline erosion control structure using both existing and new stone material and rebuilding the gravel trail. This work will provide greater protection to the trail and upland areas, providing long-term erosion control and reducing the risk to public safety.

Scope of Work

The scope of work for this project includes the following components:

  • Site preparation, including installation of sediment and erosion control measures and construction fencing
  • Removal of existing stone material along the shoreline
  • Installation of a new armourstone revetment
  • Installation of a new reinforced gravel trail
  • Site restoration, including tree and shrub plantings

Construction Information

Final site restoration is scheduled to start the week of April 5, 2021.  The work is expected to take two to three weeks in duration. To ensure public safety, the previous work area (highlighted in red in the map linked below) will remain closed until site restoration is complete.

During construction hours, equipment will cross the multi-use trail at the designated crossing points to transport material to the restoration site. The multi-use trail will remain open during the workday for public use and Traffic Control Persons will be on-site to stop pedestrian and cyclist traffic when equipment is crossing the path. Please consider using the recommended detour routes during these times. The trail crossings will be fully open with no interruptions to traffic flow on evenings, weekends, and holidays.

For your safety and the safety of others, please obey all posted construction signs and stay clear of the work area and equipment. Your cooperation and patience with this undertaking is appreciated.

Public Notices

Notice of Construction signs have been placed at applicable park entrances and along affected trail routes. Notice of Construction letters will be circulated to members of the local community prior to construction. Please see the link below for a copy of the public notification.
