March 18, 2021 | Updated Project Plans

Metrolinx released the Initial Business Case along with a supplementary analysis that reveal how the project will serve the heart of major growth centres and significantly cut travel times.

Project Overview

This map of the Yonge North Subway Extension shows the route traveling beneath Yonge Street from the existing Finch Station before the alignment curves away from Yonge to emerge at the surface at the proposed subway tunnel portal south of Langstaff Road at the CN railway corridor. The path travels north within the CN railway corridor under the Highway 7 and Highway 407 overpasses on its approach to the area identified as Richmond Hill Centre. Stations at Steeles Avenue, High Tech Road, and the Highway 7/Highway 407 corridor are moving forward. Metrolinx is working with partners to determine which potential fourth station would best complement the benefits of the project. The locations planners are looking at are in line with the previously proposed stations at Cummer Avenue, Clark Avenue, and Royal Orchard Boulevard.

The proposed Yonge North Subway Extension will transform the commute in York Region, North York and beyond by extending the TTC’s Line 1 service north from Finch Station to Vaughan, Markham and Richmond Hill.

The latest plans propose up to four stations along an extension of roughly 8 kilometres. Transit hubs would be located at Steeles Avenue and within the Highway 7/Highway 407 corridor (“Bridge Station”). A station at High Tech Road would serve future communities envisioned within the Richmond Hill Centre area.

Further analysis is being conducted to determine which additional fourth station will be included in the final project.
