Metrolinx and Infrastructure Ontario have selected Scarborough Transit Connect as the development partner for the Stations, Rail and Systems (SRS) contract for the Scarborough Subway Extension in Toronto.
This project will deliver the 7.8-kilometre Scarborough Subway Extension in two primary contracts: the SRS contract and the Advance Tunnel contract, which is currently under construction. The subway will be operated by the Toronto Transit Commission (TTC) as part of Line 2.

Scarborough Transit Connect is comprised of Aecon Infrastructure Management and FCC Canada as the applicant leads; Mott MacDonald Canada as the design prime team member; and Aecon Infrastructure Management and FCC Canada as the construction prime team members.
The scope of the work for the SRS contract includes:
- The design and construction of three new underground stations and bus terminals at each station
- The design and construction of emergency exit buildings, service buildings and traction power substations
- The installation, testing and commissioning of all systems equipment and interconnection with existing TTC systems
- The design, supply, installation, testing and commissioning of all rail and track components and a pocket track east of Kennedy Station
- Coordination with the Advance Tunnel contractor on remaining work
The development phase for SRS is expected to be completed in approximately 18 to 24 months. Once this phase has concluded, Metrolinx and the Scarborough Transit Connect team will have the option to sign a final agreement for the construction phase.
The Scarborough Subway Extension is one of the five priority transit projects taking place in the Greater Toronto and Hamilton Area. The other projects include the Yonge North Subway Extension, the Eglinton Crosstown West Extension, the Ontario Line and the Hamilton LRT.
