The Scarborough Subway Extension (SSE) extends Line 2 (Bloor-Danforth Subway) by 7.8 km from Kennedy Station to a new terminus at Sheppard Avenue and McCowan Road. The SSE will run below grade from the existing Kennedy Station to a new terminus at Sheppard Avenue East via Eglinton Avenue, Danforth Road and McCowan Road, with three new stations.

The project has been identified as the sole responsibility of Metrolinx in the Getting Ontario Moving Act (Bill 107) and Ontario Regulation 248/19 Interim Measures – Upload of Rapid Transit Projects.
