The Ontario Line is a 15.5 kilometre rapid transit line that will connect the Ontario Science Centre to the Exhibition/Ontario Place grounds and provide relief to Line 1 (Yonge-University).
For more information about the project, or to find information about past and future public engagement, please visit Metrolinx’s Ontario Line project page.
The Ontario Line is an initiative under the Metrolinx-led Subway Program. It will have 15 stations, including six interchange stations that will connect to GO train services at Exhibition/Ontario Place and East Harbour, to the existing subway network on Line 1 at Queen Station and Osgoode Station and on Line 2 at Pape Station, and to the future Eglinton Crosstown LRT at the Ontario Science Centre station. The Ontario Line will utilize a fully automated system that will enable higher frequency of trains.
The Ontario Line is being built under three separate public-private partnership (P3) contracts:
Requests for Proposals for the RSSOM and the Southern Civil contracts closed in June 2022. Contracts are expected to be awarded in fall 2022.
Requests for Qualifications (RFQ) for the Northern Civil contract is targeted for release in 2022.
Early works construction at Exhibition Station began in March 2022, to set the groundwork for major construction in the area. Additional early works for the Lower Don Bridges, Lakeshore East Joint Corridor, and utility works at Queen Station and Osgoode Station will commence throughout the remainder of 2022.
Major construction for the Ontario Line is anticipated to begin in 2023 as part of the RSSOM and Southern Civil contract packages of work.
