Metrolinx has signed a $5.7B Target Price Agreement with Scarborough Transit Connect (STC) to design and build the Scarborough Subway Extension Stations, Rail and Systems (SRS) project.

As the first Progressive Design-Build transit project to reach contract award, it is also notably the first Target Price Agreement executed within the transit asset class in Ontario, providing Metrolinx with greater reliability in pricing, risk, scope and schedule.

The Progressive Design-Build model incorporated a two-year design process for this project, known as the Development Phase. Metrolinx and Infrastructure Ontario selected Scarborough Transit Connect as the development partner in November 2022, following a competitive and transparent procurement process.

Over the past two years, STC and Metrolinx have collaborated on design, costing, scheduling, early investigations and applicable early works. Now that all conditions have been finalized and accepted, a Target Price Agreement has been awarded to the Scarborough Transit Connect team.

Target Price refers to a jointly determined estimate by Metrolinx and STC of the total capital cost required to deliver the project.

The Scarborough Transit Connect team includes:

  • Applicant Leads: Aecon Infrastructure Management Inc., Fomento de Construcciones y Contratas Canada Ltd. 
  • Construction Team: Aecon Infrastructure Management Inc., Fomento de Construcciones y Contratas Canada Ltd. 
  • Design Team: Sener 

The scope of work for the SRS contract includes:

  • Design and construction of three new underground stations and bus terminals at each station.
  • Design and construction of emergency exit buildings, service buildings and traction power substations.
  • Installation, testing and commissioning of all systems equipment and interconnection with existing TTC systems.
  • 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.

Metrolinx is delivering the 7.8-kilometre Scarborough Subway Extension through two large contracts: the SRS contract and the Advance Tunnel contract. The subway will remain publicly owned by the Province of Ontario and operated by the TTC as part of Line 2. 

The Scarborough Subway Extension is one of the five priority transit projects 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.
