Scarborough Subway Extension

A Subway for Scarborough

The proposed Scarborough Subway Extension will bring the TTC’s Line 2 subway service nearly eight kilometres farther into Scarborough.

It will extend from Kennedy Station to Sheppard Avenue and McCowan Road, providing quick and seamless transit for those heading into and out of the downtown core and those travelling within Scarborough. The extension will replace Line 3 (the Scarborough RT), helping to reduce travel times and improve access to jobs, schools and other key destinations throughout the city.

Metrolinx and Infrastructure Ontario are working together to deliver the Scarborough Subway Extension, which is estimated to be complete by 2029-30.

A Message From the Project Team

Scarborough Subway Extension project director Mark Ciavarro has seen a lot of exciting growth over more than a decade at Metrolinx. Get to know Mark and find out how the project will transform the commute in Scarborough and beyond.

Where will it take me?

Stations are proposed at Lawrence Avenue and McCowan Road, Scarborough Centre, and Sheppard Avenue and McCowan Road.

The proposed extension will connect to a number of other transit systems to make it easier to travel within the city and beyond. Kennedy Station will provide connections to GO Transit rail services and the Eglinton Crosstown LRT, and the proposed station at Scarborough Centre will connect to GO and proposed Durham-Scarborough Bus Rapid Transit services. There will also be local TTC bus connections at every stop along the extension.

All alignments, stations, stops, locations, names and quantity of stations/stops are conceptual and subject to change.

Faster and More Convenient Travel

The proposed Scarborough Subway Extension will improve the customer experience by providing better access to the subway system and minimizing the number of transfers required to get to and from downtown Toronto.

It will also provide a station north of Highway 401 at Sheppard, meaning customers from the northern parts of Scarborough will also spend less time on buses. For drivers, there will be fewer buses on the road as they will be able to terminate at Sheppard and McCowan instead of Scarborough Centre.

Get Involved

Information from our latest virtual engagement for the Scarborough Subway Extension is available on the Metrolinx Engage portal. Check out the latest project updates and what to expect when tunnelling gets underway.

An addendum to the original Scarborough Subway Extension environmental assessment (2017) was needed to reflect the changes to the Scarborough Subway Extension. The addendum to the 2017 EPR was published for public review on July 10, 2020, with comments received to the Project email TorontoEast@Metrolinx.com through August 3, 2020. The EPR Addendum has now been updated, as of August 7, 2020, and is available in the Project Documents section.
