About the Project:

The Yonge North Subway Extension (YNSE) will extend the TTC’s Line 1 subway service approximately 8 kilometres from the existing terminus at Finch Station into the City of Richmond Hill. This is a cross-jurisdictional project spanning the City of Toronto and York Region, including sections within the cities of Markham, Vaughan and Richmond Hill. It will include an approximately 6.1-kilometre underground tunnel segment. Once complete, the YNSE will connect with local and GO transit services. 

The Yonge North Subway Extension is one of four priority transit projects announced by the Province in 2019 for the Greater Toronto and Hamilton Area. Planning is underway for all four subway projects and procurements for the subway program are being staged to ensure each project is delivered successfully.

The Yonge North Subway Extension is being delivered in separate procurement contracts:

  1. An advance tunnel between Finch Station and Richmond Hill: RFQ issued April 22, 2022.
  2. A contract to construct the stations and other facilities, fit out the tunnel and install and commission the systems (Stations, Rail and Systems).
