The development phase is expected to start in fall 2022.

The 7.8-kilometre Scarborough Subway Extension is being delivered in two large contracts: the SRS package and the advance tunnel contract. The tunnel contract was awarded on May 25, 2021 to Strabag.

The Scarborough Subway Extension is one of four priority transit projects announced by the Province in 2019 for the Greater Toronto Area. In May 2021, the Government of Canada announced funding for Ontario’s four transit priority projects in the Greater Toronto Area, including the Ontario Line, a three-stop Scarborough Subway Extension, the Yonge North Subway Extension and the Eglinton Crosstown West Extension. Planning is underway for all four subway projects and procurements for the subway program are being staged to ensure each project is delivered successfully.
