“The RFP release is the next critical step in our government’s plan to extend subway service north from Finch Station to communities in Markham, Vaughan and Richmond Hill, for the first time ever,” said Minister of Transportation Prabmeet Sarkaria.

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 Advance Tunnel Contract includes work to design, build and finance the construction of tunnels and the TBM launch and retrieval shafts.

The issue 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 the existing Line 1 service, is now substantially complete. The upgrades set the stage for major construction of the subway extension.

The 8km extension is one of Ontario’s four priority subway projects for the Greater Toronto Area. Ontario is investing C$70.5bn (US$51.6bn) over the next decade on the largest subway expansion in Canadian history, which includes the Ontario Line, the Scarborough Subway Extension, the Eglinton Crosstown West Extension, and the Yonge North Subway Extension.
