The Ontario government has taken a major step forward in expanding Toronto’s subway system. Infrastructure Ontario and Metrolinx have released a request for qualifications (RFQ) for the stations, rail, and systems package of the Yonge North Subway Extension (YNSE). This project is a key part of Toronto’s growing transit network, designed to connect more communities and ease congestion.
Overview of the Yonge North Subway Extension
The Yonge North Subway Extension will expand TTC’s Line 1 by approximately eight kilometres from Finch Station to Richmond Hill. This major infrastructure investment will serve thousands of commuters daily and boost economic growth in the GTA.
Scope of the RFQ Package
The RFQ outlines design, construction, supply, integration, and commissioning of multiple systems critical to the extension’s operation. It is one of the largest transit contracts currently moving forward in Ontario.
Five New Subway Stations Planned
The project will deliver five new subway stations, each with associated bus terminals. This will improve regional connectivity and give commuters more seamless transfer options.
Emergency Exit Buildings and Safety Measures
Safety is a priority in the design. The plan includes emergency exit buildings, traction power substations, and tunnel cross passages to meet high safety and reliability standards.
Rail and Signalling Systems
A full rail and signalling system installation is part of the package. This ensures smooth integration with Line 1’s existing operations and supports future ridership demand.
Train Storage Facility to Support Line 1
To handle increased service, a train storage facility will be built. This facility will enhance TTC’s operational efficiency and support ongoing Line 1 service expansion.
Connection to Finch Station
The extension begins at Finch Station, with connections and modifications to the existing tail track. This integration ensures uninterrupted service for current subway riders while extending capacity northward.
Integration with Existing TTC Infrastructure
The RFQ also includes coordination with ongoing advance tunnelling work and integration with existing Line 1 systems. Seamless operations between old and new infrastructure is key to the project’s success.
Transit-Oriented Communities Program
The RFQ includes provisions for future transit-oriented communities (TOCs). These TOCs will help create mixed-use neighborhoods around new stations, combining housing, retail, and services.
Procurement Process and Next Steps
This RFQ is the first step in selecting a qualified team to deliver the project. Shortlisted applicants will later be invited to participate in the Request for Proposals (RFP) stage, which finalizes the contract.
