About The Project

The Ontario Line is a 15.6-kilometre stand-alone rapid transit line in Toronto that will connect the Flemingdon Park neighbourhood to Exhibition/Ontario Place. Over half of the route is planned to run underground through new tunnels, with the remainder running along elevated and at-grade rail corridor sections of track. Fifteen stations are proposed, with numerous connections to the broader transit network, including GO Transit rail services, the Toronto Transit Commission’s subway Lines 1 and 2, and the future Line 5 (Eglinton Crosstown LRT).
