The Scarborough Subway Extension is an six-kilometre extension of Toronto’s Line 2 subway system, providing a direct link from Kennedy Station to Scarborough Centre. The new line will run along the McCowan Corridor, with the new station located on the west side of McCowan Road between Triton Avenue and Progress Avenue. The project also includes a new bus terminal to link subway riders to local and regional bus routes.

Originally, the Scarborough transit project had been designed as a seven-stop light rail transit system, and had received funding from both the federal and provincial government. The funding envelope, including the contribution from the municipality, sat at $3.56 billion, just over $200 million more that the current anticipaited cost of the one-stop subway.

The Ford government has installed the Scarborough Subway Extension into its estimated $28.5 billion transit plan for Toronto, which would re-institute a three-stop subway. Under the new plan, the Request for Qualifications for the project would be released in 2021, with completion by 2030. A final cost of the project has not yet been determined, however the estimate provided at the time of the announcement (April 2019) was $5.5 billion. As the scoping had not been finalized by the time this report was released, the project value remains at the number committed to by the municipality, which is the aforementioned $3.56 billion.
