Ontario Making Progress on Yonge North Subway Extension

December 1, 2023

Province Issues Request for Proposals to Advance Tunnelling Work

The Ontario government is taking another step forward to get shovels in the ground on the Yonge North Subway Extension by issuing a Request for Proposals (RFP) for the contract to design and build the subway’s tunnels. The Yonge North Subway Extension is one of Ontario’s four priority subway projects for the Greater Toronto Area (GTA) and will deliver much-needed rapid transit between York Region and Toronto.

After being shortlisted through a Request for Qualifications (RFQ) process earlier this year, CrossTransit Group, North End Connectors and Toronto-York Tunnel Connectors are being invited to respond to the RFP with proposals that detail how they will deliver the tunnelling project. The contract for the tunnelling project is expected to be awarded in late 2024.

The issuance of the RFP comes as the project reaches another important milestone. Early upgrade work at Finch Station, where the Yonge North Subway Extension will connect with existing Line 1 service, is now substantially complete. The upgrades set the stage for major construction of the subway extension.

Once in service, the approximately eight-kilometre subway extension will provide over 94,000 daily trips, connect more people to jobs and housing, and bring faster transit and more convenience to communities across York Region and Toronto.
