Metrolinx breaks ground on four new stations

Major Ontario Line progress taking shape in Toronto’s east end

Feb. 23 – Crews have broken ground on four new Ontario Line subway stations in Toronto’s east end.  

Three of these stations – Thorncliffe Park, Flemingdon Park and Don Valley stations – are situated along a raised section of tracks that will carry the trains between them, which is also now under construction. Further south, crews are also breaking ground at the below-ground Cosburn Station.  

Stretching nearly three kilometres across the city’s east end, the section of elevated tracks —known as an “elevated guideway” – will run from Overlea Boulevard in Thorncliffe Park, connecting to Thorncliffe Park Station, then continue north along Don Mills Road to Flemingdon Park Station and then Don Valley Station, where it will link with Line 5 Eglinton. The elevated guideway will form one of the most distinctive and architecturally significant sections of the new transit line.  

Construction on these stations builds on major work already underway in the east end and beyond. The elevated guideway will connect to underground tunnels running underneath Pape Avenue, which will link up with Cosburn and Pape stations. At Pape, crews are digging down to the existing TTC station, having already excavated 20 per cent of the soil—roughly 24,000 cubic metres. 

Bridge work is also in full swing across the project, with three new crossings taking shape at the West Don, Don Valley and Lower Don. At the same time, existing rail bridges are being upgraded throughout Riverside and Leslieville. 

Station excavation is underway or completed at all downtown sites from Corktown to Exhibition, and crews are starting to add concrete, steel and other permanent station components.

At Exhibition, crews are preparing to launch tunnel boring machines (TBMs), Libby and Corkie, later this year. Construction is also well underway at a second launch shaft at Gerrard Street, where two additional TBMs will begin their journey to carve out the northern tunnels.   

Major Ontario Line construction in the city’s east end is a big step toward faster, more reliable transit for Torontonians. Once open, the line will cut travel from Thorncliffe Park to downtown by 15 minutes—shrinking a 40-minute trip to just 25—and connect to more than 40 other transit options, making it easier than ever to get around the city and beyond.
