The Ontario Line is a 15.6-kilometre stand-alone rapid transit line that will connect the Ontario Science Centre 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, the future Line 5 (Eglinton Crosstown LRT), as well as numerous bus and streetcar routes. The Ontario Line is one of four priority transit projects announced by the province in 2019 for the Greater Toronto and Hamilton Area.

In November 2022, Infrastructure Ontario and Metrolinx awarded a contract to Connect 6ix valued at $9B ($2.3B for capital costs and $6.7B for short-term construction financing and transaction costs, train costs and 30-year operations and maintenance, lifecycle, and long-term financing). The Connect 6ix team will design, build, finance, operate and maintain the Ontario Line Rolling Stock, Systems, Operations and Maintenance (RS.SOM) package for a 30-year term.

The team will begin mobilizing their design and construction crews, with work to commence in 2023. The project is anticipated to be completed in 2031. Once all the civil infrastructure elements and systems from Ontario Line North and South segments have been completed, integrated and certified, Connect 6ix will then begin operating and maintaining the Ontario Line for a 30-year term.
