About the Project:

The Scarborough Subway Extension (SSE) Advance Tunnel Project is the first phase of work for the 7.8 kilometre extension of TTC's Line 2 (Bloor-Danforth), from Kennedy Station to McCowan Road/Sheppard Avenue.

Starting with the tunnelling phase of work allows a significant portion of the subway extension to move forward on an accelerated timeline.

A separate contract will be issued in the future for the rest of the work, which includes building the stations, fitting-out the tunnel and installing and commissioning the systems to put the subway in service.
