The City is planning to construct a number of upgrades to the storm and sanitary sewer system in the Midtown area. These upgrades were recommended in the 2014 Basement Flooding Class Environmental Assessment (EA) report for Area 17. Study Area 17 is roughly bounded by Bathurst and Dufferin Streets, Highway 401 to Roselawn Avenue in the Eglinton-Lawrence Ward. To obtain a copy of the completed EA, contact twcustomercare@toronto.ca.

The project includes:

  • Upgrades to approximately 8 km of conveyance sewers, roughly 3 km of which will be constructed via tunneling
  • Part of the conveyance improvements are to support the Lawrence-Allen Revitalization Plan (LARP)
  • Construct a stormwater storage tank facility under Memorial Park
  • Install/upgrade 80+ High Inlet Capacity (HIC) catch basins

These works are part of the City’s Basement Flooding Protection Program to help reduce the risk of future basement flooding.

The Federal Government through the Disaster Mitigation and Adaptation Fund (DMAF) will provide the City with $37.16 million towards funding for the Midtown Toronto Relief Storm Sewer project.

The detailed design for the new sewer system upgrades is currently underway and expected to continue into 2023.

The preliminary design for the project was completed in 2019.

Construction for this project is expected to begin in 2024 and be completed in 2028.
