Ontario Line progress is ramping up from west to east

Explore construction updates along Toronto’s Ontario Line subway route.

Jun 3, 2025

From Liberty Village to the Don Valley and beyond, construction is picking up across the future Ontario Line subway route.

At Exhibition Station, excavation continues at the tunnel launch shaft where tunnel boring machines will begin their journey beneath downtown Toronto. Existing tracks have been shifted to make room for new Ontario Line structures, including shared platforms for GO and Ontario Line trains. Work has also begun on two new station entrances north and south of the tracks.

Downtown, excavation is underway at all station sites, from King-Bathurst to Corktown. Acoustic shelters are being installed at some locations like King-Bathurst, Osgoode and Queen to reduce noise from overnight excavation.

In the Don Yard, excavation continues on the tunnel portal – the transition between underground and surface level tracks. On the east side of the site, crews are also building a temporary support for the new Lower Don Bridge.

East of the Don River, in the Lakeshore East shared rail corridor, weekend track closures in March and April allowed crews to lay nearly two kilometres of new track and shift close to 900 metres of existing track to make room for the Ontario Line.

At Pape and Danforth, slurry wall work is complete, and the site is now getting prepped for excavation of the future Ontario Line connection to Pape Station.

Further north, early work continues to prepare for elevated guideways that will cross the Don Valley, with crews soon to begin constructing support piers.

And finally, work continues at the site of the subway’s future operations, maintenance and storage facility in Thorncliffe Park, where crews are setting the stage for excavation.

With 15 stations and 15.6 kilometres of new track, the Ontario Line will transform the way we move around Toronto.
