Massive Work Progresses at Queen-Spadina Ontario Line Station

Queen-Spadina Ontario Line station is quickly taking shape beneath one of Toronto’s busiest intersections as crews dig deep to prepare for the next phase of construction. This is reported by the railway transport news portal Railway Supply.

The new station forms a crucial part of the $27 billion Ontario Line, which stretches 15.6 kilometres between Exhibition Place and the former Ontario Science Centre.

At the Queen-Spadina site, workers have carved a cavern that will house the platforms and tracks. This large underground void is being expanded to fit tunnel boring machines and final station infrastructure.

Metrolinx reports that excavation has reached the station’s end walls. These structures serve as limits for tunneling operations and indicate major construction progress.

The work site is divided into north and south zones. Teams are removing rock and soil using sequential excavation, working continuously, seven days a week.

Spoils are transported through the north site, allowing uninterrupted activity below the downtown core. Crews use advanced equipment to manage the confined space and tight timeline.

The Queen-Spadina Ontario Line station has already completed full-length excavation. Now, the focus is on widening and deepening the cavern ahead of the upcoming tunneling.

Soon, boring machines will enter through the southern headwall and pass through the cavern toward the northern edge to dig out the main tunnel route.

Excavation Advances at Queen-Spadina Ontario Line Station

At the southern site, excavation continues to form the lower end of the station. Meanwhile, northern teams prepare for equipment positioning and tunnel launch readiness.

According to Metrolinx, 50 percent of total excavation is now complete. This phase is scheduled to wrap up later this year if current pace holds.

Queen-Spadina Ontario Line Station to Support Future Tunneling

The station cavern will soon serve as a launch corridor for tunnel boring machines. These devices will carve the line’s underground path from Liberty Village to the Don River.

The Ontario Line remains on track to open in 2031, delivering faster downtown connections and improved transit capacity across Toronto.
