The digging process of the north shaft has been completed on the Ontario Line’s Queen-Spadina subway station in Toronto.
Also crews are due to link the newly completed station shaft to the future station platform area and excavate in a south-west direction away from the north-east corner of Queen Street and Spadina Avenue, over the next phase of excavation, which will continue into early 2026.
In order to creating the Ontario Line subway tunnels through downtown Toronto, this cavern is also going to create space for the future tunneling machines to pass through.
With the aim of being assembled and operated, crews will deliver specialised machinery into the excavated shaft at the north site anf the machines will use sequential excavation.
Following completion, the Ontario Line is slated to be a 15.6km subway that will bring 227,500 more people in Toronto within walking distance to transit, that will include 15 stations and more than half the route will be underground.
