About the Project:

The Scarborough Subway Extension is a 7.8 kilometre extension of TTC's Line 2 Bloor-Danforth Subway, from the existing Kennedy Station northeast to McCowan Road/Sheppard Avenue. The line will include three new stations at Lawrence Avenue and McCowan Road, Scarborough Centre and a terminal station at McCowan Road and Sheppard Avenue. The project is being delivered in two large contracts: the Stations, Rail and Systems package and the Advance Tunnel project.

The Scarborough 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.

Demonstrating Value

  • The project is being delivered using a Design-Build-Finance (DBF) model. Key benefits of a DBF model include significant risk transfer to the private sector over the life of the project agreement, greater cost and schedule certainty and greater potential for design and construction efficiencies and innovation.
  • Based on precedent project experience, a DBF procurement model typically has delivered a value for money savings in the range of 10% to 15% compared to undertaking the same projects using traditional delivery models.
