Toronto is embarking on the largest and most significant stormwater management program in the city’s history. With an overall budget of more than $3 billion, this program will greatly improve the water quality in the Lower Don River, Taylor-Massey Creek and along Toronto’s Inner Harbour by keeping combined sewer overflow out of our waterways through the upgrading of technology and capacity to capture, transport and treat it.
In 1987, the International Joint Commission identified the Toronto’s waterfront as one of 43 polluted “Areas of Concern” in the Great Lakes Basin, largely because of impaired water quality and sediment conditions in the Don River and Inner Harbour.
Water quality in the Lower Don River, Central Waterfront and Taylor-Massey Creek is degraded due to:
The Program is the largest and most significant water quality improvement undertaking in the City of Toronto.
After years of study and design work, construction will begin in 2018. Once fully implemented, the Program will virtually eliminate the release of combined sewer overflows into the Lower Don River, Taylor-Massey Creek and Toronto’s Inner Harbour. It will also provide erosion and sediment control in Ashbridges Bay.
When fully implemented, the project will:
The Program in place today is based on extensive research, analysis, input from the public, agencies, and other stakeholders. This includes:

The program will greatly improve the water quality in the Lower Don River, Taylor-Massey Creek and along Toronto’s Inner Harbour.
The three tunnels capture combined sewer overflow (stormwater mixed with raw sewage), thereby keeping it out of:
The tunnels capture the combined sewer overflow and transport it down to Ashbridges Bay Treatment Plant – where it will be:

As with all construction projects, disruptions to the local community will occur. Every effort will be made to keep residents informed and disruptions to a minimum. Once construction is completed, sites will be restored and enhanced in consultation with the local community.
