The governments of Canada and Ontario officially broke ground on the elevated guideway and four new stations for the Ontario Line subway.
“The Ontario Line will be a game-changer for GTA residents, cutting travel times across Toronto and offering more than 40 convenient connections to other transit services across the region,” said Premier Doug Ford.
Crews have begun work along the three-kilometre elevated guideway, a raised stretch of track that will connect Don Valley, Flemingdon Park and Thorncliffe Park stations, where ground has also now been broken. This section will bring 30,500 people within walking distance of a subway stop and improve access to 14,800 jobs in the area.
“With work underway at all Ontario Line stations south of Bloor-Danforth, and iconic bridges being built over the Don River, we are delighted to begin construction of the four northern stations which will put more than 40,000 residents within walking distance of this incredible project,” said Michael Lindsay, president and CEO, Metrolinx.
The Ontario Line is No. 7 on ReNew Canada’s 2026 Top100 Projects report.
The province is also breaking ground at Cosburn Station, which will connect riders across the city to Toronto’s Pape Village neighbourhood for the first time and cut commute times for more than 10,000 people. Once complete, the 15.6-kilometre Ontario Line will have 15 stations, running from Exhibition Place through the downtown core and connecting to Line 5 Eglinton at Don Mills Road.
“The Ontario Line will connect people and communities across our city, helping hundreds of thousands of Torontonians get where they need to go faster and more reliably,” said Olivia Chow, Mayor of Toronto. “This new line will bring more people within walking distance of transit, reduce congestion on our roads, and make daily commutes shorter for families and workers.”
The elevated guideway will carry Ontario Line trains up to 14 metres above street level, starting at the west end of Overlea Boulevard in Thorncliffe Park and running north to Don Valley Station at Don Mills Road and Eglinton Avenue East.

“Advancing construction of the Ontario Line’s elevated guideway and four new stations means we are another step closer to enhancing connection and productivity in our nation’s largest city. Together, we will build a stronger and more resilient Canadian economy for everyone,” said Julie Dabrusin, Minister of the Environment, Climate Change and Nature and MP for Toronto-Danforth.
In October 2024, the province broke ground on two new bridges over the Don Valley, laying the foundation for faster transit and cutting travel times by more than half for families and workers along the route.
In July 2024, the province broke ground on the Ontario Line’s Pape Station. To date, crews have excavated 20 per cent of the site, roughly 24,000 cubic metres of soil.
