Scarborough Subway Extension station rendering

Partner selected for Scarborough Subway Extension stations

Development partner to help design remaining parts of 7.8-km subway extension.

Dec 5, 2022

Metrolinx continues to make significant progress on the Scarborough Subway Extension with the selection of Scarborough Transit Connect as the development partner for the project’s stations, rail, and systems.

With three new stations across nearly eight kilometres of new subway tracks, the extension is expected to put convenient, modern rapid transit within a 10-minute walk of 38,000 more people.

Scarborough Transit Connect will play a key role in preparing more detailed plans for the stations, bus terminals, subway tracks, and other technical components that will bring the project to life.

The development phase

To deliver the Scarborough Subway Extension as quickly as possible, construction has been split into two contracts – an advanced tunnelling contract that is already underway, and the stations, rail and systems (SRS) contract. The SRS contract is kicking off with a development phase before the construction phase begins, with Scarborough Transit Connect selected as the partner for the development phase.

This consortium is made up of the following experienced local and international companies:

  • Aecon Infrastructure Management Inc., FCC Canada Ltd. – applicant leads;
  • Mott MacDonald Canada Limited – design prime team member;
  • Aecon Infrastructure Management Inc., FCC Canada Ltd. – construction prime team members.

Metrolinx will collaborate with Scarborough Transit Connect during the development phase on final designs for the stations, rails, and operating systems that will complement the new tunnel being built.

The development phase will provide opportunities to gather input from other project partners and the community before proceeding to construction of this critical project.

The three new stations

Metrolinx released new station maps earlier this year showing the proposed station buildings, and entrances and exits for the stations.

All three stations are being designed to maximize benefits to the community and future transit riders.
