Introduction

Infrastructure Ontario and Metrolinx have issued a request for qualifications (RFQ) for the stations, rail, and systems design-build-commission package for the Yonge North subway extension, which will extend the Toronto Transit Commission’s Line 1 subway service 5 miles from Finch Station into Richmond Hill.

Project Overview

The Yonge North subway extension project will span Toronto and the York region.

Scope of Work

The scope of work encompasses the design, construction, supply, integration, and commissioning of several key components. These include five new subway stations and associated bus facilities, emergency exit buildings, traction power substations, and tunnel cross passages. Additionally, the project includes all rail and signaling systems, a train storage facility, and modifications to the existing tail track at Finch Station. The integration of new track with the existing Line 1 infrastructure and tunneling work currently underway is also part of the project. Furthermore, the project will include provisions to enable work on Ontario’s Transit-Oriented Communities program.
