Bluffer’s Park South Headland and Beach Major Maintenance Project

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

Project Location

The project area is located in Bluffer’s Park, at 1 Brimley Road South, at the base of Brimley Road in Scarborough, City of Toronto. The area of concern includes the southernmost headland and adjacent beach, located at the southwest limits of the park on the north shore of Lake Ontario.

Project Background

Bluffer’s Park was built as part of a large lakefilling operation from the early 1960s to mid 1970s, and includes a series of armourstone headlands, beaches, and revetments for erosion control protection. The landform has been used as a public park since its construction, and features formal walking trails, public beaches, marinas, and open green spaces that overlook Lake Ontario. The project area includes the southernmost headland and its adjacent beach; the headland is lined by an armourstone revetment and the beach is constructed of a mix of cobble, gravel, and concrete rubble material.

In 2006, TRCA began conducting annual inspections of the structures within Bluffer’s Park as a part of the Erosion Risk Management Program (ERMP). The ERMP has assessed the headland structure as at-risk since 2010, and in failing condition since 2015. The beach has been listed as a failing structure since 2010. In 2017, a weak spot was identified at the southern tip of the headland, where continued wave action resulted in the loss of much of the structure material.

On April 14-15 2018, the Toronto Region experienced a severe ice storm which caused extreme wave action in Lake Ontario. The waves caused significant damage to the headland and beach, washing large amounts of stone material into the lake and onto the park tableland, and scouring the shoreline. The wave activity from the storm resulted in the complete collapse of the weakened portion of the headland.

In the spring of 2018, TRCA retained Riggs Engineering Limited to develop engineered design solutions for repair of the damaged structures. An interim design was developed and implemented to temporarily stabilize the headland while a long-term solution was in development. Interim works were completed in January 2019 and involved the placement of armourstone in the large failure section of the headland. These works were designed to provide temporary protection to the parkland for the winter and spring months when ice and wave action place the structure at increased risk for further damage. The interim solution is intended to prevent further damage to the park until the long-term solution can be implemented. The long-term solution includes repair of the remainder of the headland as well as the adjacent beach, and will be implemented in two phases.

Scope of Work

The general scope of work for the Project includes the following items:

Completed steps:

  • Phase I: Interim Works – completed in January 2019

Next steps include:

  • Obtain all required permits and approvals for implementation of long term solution
  • Phase II: Headland Long-term Works – Summer 2019*
  • Phase III: Beach Long-term Works – Summer 2020*
      * Timelines are subject to change 

The scope of work for 2019 includes the completion of detailed designs for the long-term solution, which include repair of the headland and the adjacent beach. Implementation of Phase II: Headland Long-term Works is scheduled for Summer 2019. All necessary permits and approvals will be obtained for the implementation of works prior to construction. Construction of Phase III: Beach Long-term Works is tentatively scheduled to begin Summer 2020, pending the receipt of all required permits and approvals.

Construction Information

Construction of Phase II: Headland Long-term Works is scheduled to commence June 18, 2019 and is anticipated to be complete by July 2020.

To ensure public safety, the headland area will be closed for the duration of the work. Other areas of the park required for construction access, including trails within the limits of construction and the beach, will be closed on weekdays and reopened on the weekend throughout the duration of the work. For your safety, please respect all posted construction signs and stay clear of the work areas and equipment. Your cooperation and patience with this undertaking is appreciated. Please see the map below for details.

Progress Updates

Update: July 5, 2019

Site setup has commenced. The work area has been fenced off and erosion and sediment control measures have been installed. Tree hoarding measures have also been completed.

Update: July 11, 2019

With site setup completed and erosion and sediment control measures in place, the replacement of the headland’s revetment has commenced.

Update: October 7, 2019

Construction continues on the revetment. Crews are replacing the armourstone along the revetment with new and suitable reusable materials. A second layer of armourstone is being added to the headland for added protection against wave action.
