On Wednesday, Metrolinx and Infrastructure Ontario (IO) confirmed the development partner for the Stations, Rail and Systems (SRS) contract for the Scarborough Subway Extension. Scarborough Transit Connect has been tasked with designing and building the station, laying down tracks, and installing the technology that will connect the extension to the Line 2 subway.

Scarborough Transit Connect -- an aggregate of leading Canadian companies -- was shortlisted for the contract back in February, along with three other teams. The team was evaluated and selected based on several criteria, including “design and construction methodology, approach to managing the project, and corporate overhead and profit fees for the project,” according to a news release issued yesterday. “The open, fair and competitive procurement process was overseen by a third-party fairness monitor.”

Scarborough Transit Connect is comprised of:

  • Applicant Leads: Aecon Infrastructure Management Inc., FCC Canada Ltd.
  • Design Prime Team Member: Mott MacDonald Canada Limited
  • Construction Prime Team Members: Aecon Infrastructure Management Inc., FCC Canada Ltd.

The SRS package for the Scarborough Subway Extension will be delivered using a Progressive Design-Build model, which hinges on a multi-stage design process called a development phase. According to the release, “this phase allows for a collaborative approach between the project owner, the contracting partner and other stakeholders who work closely together to finalize the scope, risk allocation and pricing of various elements of the project.”

The development phase for SRS is expected to take around 18 to 24 months, at which point, Metrolinx and Scarborough Transit Connect will sign a final agreement to proceed to the construction phase.

The SRS package is the second of two contracts, the first of which -- the Advance Tunnel contract -- was awarded in May 2021 and is currently underway.

The 7.8-kilometre Scarborough Subway Extension is slated for competition in 2029. Upon completion, Line 2 will extend nearly eight additional kilometres into Scarborough, from Kennedy Station to Sheppard Avenue and McCowan Road. The extension will replace Line 3, the Scarborough RT, and is intended to reduce travel times, and improve access to jobs, schools, and City of Toronto services.
