The Scarborough Subway Extension project is a 6.2 km extension of Line 2 from Kennedy Station to Scarborough Centre, via Eglinton Avenue, Danforth Road and McCowan Road. The extension will create a seamless journey for customers by eliminating the transfer at Kennedy Station. The Line 2 extension is required to replace the aging Line 3 Scarborough.

In October 2013, City Council confirmed support for an extension of Line 2. In March 2017, City Council confirmed support for the one-stop McCowan alignment from Kennedy Station to Scarborough Centre. The Municipal, Provincial and Federal Governments have each committed funding to make the extension a reality.

The future Scarborough Centre Station will be located on the west side of McCowan Road, between Triton Road and Progress Avenue beneath a future extension of Borough Drive. The project also includes a bus terminal to serve local and regional routes.
