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.

Construction of the line is scheduled to begin in 2019, with project completion expected in the second quarter of 2026.
