This addition will provide a critical extension for the existing TTC subway system across the municipal boundary between Toronto and the Regional Municipality of York. This is the largest subway expansion project ever to be undertaken by the TTC since the Bloor-Danforth subway line was built 40 years ago.

The 8.6-kilometre extension to the existing Spadina line will include six new stations: Sheppard West, Finch West, York University, Pioneer Village at North West Gate and Steeles Avenue, Highway 407, and the Vaughan Metropolitan Centre. The first of four tunnel-boring machines for the extension was launched in June 2011. Construction work on the Highway 407 station is progressing well, with the south tunnel having been completed and construction of the north tunnel soon to commence. Project completion is expected in 2017.
