The Ontario Line involves the development of 15.5 km free-standing rapid transit line, connecting Ontario Place/Exhibition through downtown Toronto to the Ontario Science Centre. The line will better connect people to where they want to go, and reduce travel times across Toronto. 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, the future Line 5 (Eglinton Crosstown LRT), as well as numerous bus and streetcar routes.

The Ontario Line is being delivered as three separate public-private partnership (P3) procurement contracts:

1. Rolling Stock, Systems, Operations and Maintenance Contract 
2. Southern Civil, Stations and Tunnel Contract 
3. Northern Civil, Stations and Tunnel Contract
