Six downtown Toronto stations on the Ontario Line are being carved dozens of metres underground, with crews actively lining walls and pouring concrete at multiple sites. The 15.6-kilometre extension with 15 stops is projected to open in the early 2030s, though the timeline and cost have shifted significantly since the project's launch.
At Chinatown Station (formerly Queen-Spadina), which will serve Chinatown, Queen West, and Kensington Market, work is underway on rebar installation, formwork, and concrete pours at the southern access site. Base slab work is scheduled to continue through September, and the platform level—sitting within a large cylindrical void etched from rock—is being lined with waterproof membranes ahead of platform construction.
Four of the mined stations are carved through bedrock. Twin tunnel boring machines have departed from a launch site near Exhibition Place. Piling work for the elevated guideway is now over halfway complete, with crews beginning work on the above-ground piers that will support the trackbed.
The project's estimated cost has climbed to $34 billion. The source does not state who pays for the cost or how it is funded.
