The Scarborough Subway Extension will extend the TTC’s Line 2 subway service nearly eight kilometres further into Scarborough, providing seamless, reliable transit to key areas in Toronto’s eastern hub. Stations are proposed at Lawrence Avenue and McCowan Road, Scarborough Centre, and Sheppard Avenue and McCowan Road.

The extension will travel eastward from Kennedy station, running briefly under Danforth Avenue, and then north to Sheppard Avenue and McCowan Road, generally within the McCowan Road right-of-way. The extension will strategically shift to the east and west sides of the right-of-way at certain points along the corridor to minimize construction impacts from shafts and stations. This approach will help keep traffic moving during construction and minimize disruptions to communities.

A variety of infrastructure is required for the project including bored tunnels, headwalls, underground stations and emergency exits. In advance of the construction of permanent structures, headwalls will be built during the first construction contract for:

  • Stations at Lawrence Avenue and Scarborough Centre.
  • Eight emergency exit buildings.
  • Launch and extraction shafts.

Announced by the Province of Ontario in 2019, the three-stop Scarborough Subway Extension is one of four priority subway projects Metrolinx is leading for the Greater Toronto Area (GTA).

Metrolinx has completed a number of steps this year to advance the project. We are even closer to selecting the winning bidder to deliver tunnelling on this project.

At this time, we want to provide an update to the community on the project and provide an opportunity to answer any questions that you may have.

Since our last open house earlier this year:

  • Metrolinx issued a Notice of Addendum to amend the 2017 environmental project report done for the previous one-stop proposal. The public review period closed on August 3, 2020 and all comments received were incorporated into the Updated EPR Addendum, released on August 7, 2020. This is the final environmental legislative step to advance the project.
  • Metrolinx and Infrastructure Ontario issued a Request for Proposals (RFP) on August 20, 2020, inviting three shortlisted teams to submit their bids for how they will deliver tunnelling for the project. This tunnelling contract will be awarded in 2021, followed by construction.

We are excited to share more details about the project and to receive your feedback. Visit the "Your Feedback" section to ask a question.

By extending Line 2 further into Scarborough, riders will be able to make connections to other major transit projects being planned and delivered like the Crosstown at Kennedy, the proposed Ontario Line at Pape, the proposed Durham-Scarborough Bus Rapid Transit line and increased GO train service at Kennedy and Danforth stations.

All of these connections will contribute to building a more integrated transit network that will attract economic development and improve access to educational, healthcare and employment opportunities.

The SSE will attract more than 105,000 daily boardings each day, easing congestion on existing transit lines throughout the city. 34,000 jobs are expected within a 10-minute walk from new Scarborough Subway Extension stations

The three-stop extension will better serve Scarborough and the City of Toronto as a whole. The Project timeline is outlined below.

A complete timeline for the project. The tunnelling contract is expected to be awarded next year and procurement for the station, rail and systems contract is expected to being next year. The project is estimated to be complete by 2029/30.
