Ontario Line

The Ontario Line will bring nearly 16 kilometres of new subway service to Toronto to make it faster and easier for people to get where they need to be each day. The line will stretch across the city, from the Ontario Science Centre in the northeast to Ontario Place/Exhibition Station in the southwest. The Ontario Line is proposed to include 15 potential stations, including six interchange stations, and 17 new connections to GO train lines and existing subway and streetcar lines. The Project will be constructed in a dedicated right-of-way with a combination of elevated, tunneled, and at-grade segments at various locations.

Project activities will take place on mostly built-up land and may consist of activities such as site preparation, excavating/tunnelling and grading, construction of structures and bridges, and utility relocations. The project is anticipated to cross the vegetated Don River Valley at two locations. Work taking place near water includes construction of the two Don Valley Crossings, as well as the Lower Don River crossing which will involve the construction of two new bridges to accommodate the future Ontario Line tracks.
