Don Valley Brick Works Park – Mud Creek Inlet Restoration

As a result of construction, users can expect reduced access to the Belt Line Trail and DVBW trails. See Trail Impact & Detours for more information.

 

The City, in cooperation with Toronto and Region Conservation Authority (TRCA), is restoring the Mud Creek Inlet at Don Valley Brick Works (DVBW) Park.

As a result of the storm event on July 16, 2024, the embankment that separates Mud Creek from the DVBW Park wetlands overtopped and breached, resulting in failure of the embankment, and permanent damage to the water inlet and cascade feature. Following emergency stabilization, a permanent fix will now be undertaken to restore the inlet.

  • Summer 2024: Emergency patch complete
  • September 2025: Construction of permanent inlet restoration starts
  • February 2026: Anticipated construction completion
  • Fall 2026 (tentative): Additional wetland enhancements in DVBW Park

September 2025 – Inlet construction begins

Work will begin on the permanent fix to the Mud Creek Inlet at DVBW Park. Work is anticipated to be complete February 2026.

Work will include the repair of critical inlet infrastructure to restore stability to the Mud Creek channel and water flow between Mud Creek and DVBW ponds.

Summer 2024 – Emergency patch repair

Emergency works have been completed to temporarily stabilize the embankment, and engineer inspections cleared the boardwalk as safe for public access.

The City, in cooperation with TRCA, have begun work to develop a resilient design solution to permanently restore function and stability to the site, ensuring the health of the wetlands. Implementation is scheduled for fall 2025.

Construction access is required along the Belt Line Trail and within DVBW Park and will impact both trail systems for the duration of the project (anticipated September 2025 to February 2026).

  • The Belt Line Trail will remain open, but at a significantly reduced width (1 metre clearance) throughout the work zone (to be fenced for dedicated construction vehicle access).
  • A wider detour route will be available for users through DVBW park trails.
    • Two access points to DVBW from the Belt Line (the stairs and associated switchback) will remain closed throughout construction.
    • The north (Belt Line) and south access points (Bayview and Belt Line) will remain open.
    • Some trails and areas within DVBW will also be closed to facilitate this work, but alternative routes and trails will remain open throughout the park.

Project information and detour maps/signage will be installed on site.

As a result of the storm event on July 16, 2024, the embankment that separates Mud Creek from the DVBW wetlands overtopped and breached. This resulted in the ultimate failure of the embankment, significant erosion and permanent damage to the water inlet and associated cascade feature. In 2024, emergency works were undertaken to temporarily stabilize the embankment, and engineer inspections cleared the boardwalk as safe for public access.

The photo shows a rocky water cascade feature outletting water down a slope, and under a new boardwalk. There are larger and smaller rocks that make up the cascade. New trees and shrubs have been planted around it.

Now, the City, in cooperation with TRCA, have developed a permanent and resilient design solution to restore function and stability to the site, ensuring the health of the wetlands. Construction will begin on this restoration project in September 2025. The work is anticipated to be complete February 2026.

Work will include the repair of critical inlet infrastructure to restore stability to the Mud Creek channel, and water flow between Mud Creek and DVBW ponds. The completed project will resemble the original inlet water cascade feature, with the addition of a robust spillway to protect slope stability during possible future flooding/overtopping events. Sediment management will also be undertaken to re-use or remove fine sediment wash-out from the original flooding event. Sediment reused on site will be targeted for turtle nesting habitat.

Following inlet repairs, future works will address additional wetland enhancements within DVBW, including culvert and habitat feature improvements. These works will be communicated in 2026.
