Subway line in Toronto

A new 15.6-km subway line in Toronto that will run from Exhibition Place, through downtown, all the way to the Ontario Science Centre.

ACCIONA is leading the design and construction of 3 kilometers of elevated guideway and five elevated stations between the Don River Bridge and the Ontario Science Center, including connections to Line 5 Eglinton. The project will also require advance civil engineering work prior to mechanical and electrical systems installation by the RSSOM contract.

The Ontario Line will bring 15 new stations to the city of Toronto and will run from Exhibition Place in the west along the shore of Lake Ontario, through the heart of downtown, to the Ontario Science Centre to the northeast.

With a trip from one end to the other taking less than 30 minutes compared to the 70 minutes it takes on transit today, the finished Ontario Line will improve the lives of commuters. There will also be significant relief from crowding throughout the existing transit network thanks to connections to more than 40 other travel options along the way, including the TTC’s Line 1 and Line 2, three GO Transit rail lines, and the Eglinton Crosstown LRT.
