The Ontario Line subway project in Toronto has officially commenced tunnelling under the downtown area. This initiative aims to alleviate congestion in the city’s transit system and will mark the first subway tunnels constructed in the downtown core in over six decades.
Boring Machines Begin Tunnel Construction
Premier Doug Ford announced that two tunnel boring machines have started digging twin tunnels. These tunnels will extend approximately six kilometres from a launch site near Exhibition Station to a location just west of the lower Don River. Ford labeled this event as “historic” during his announcement at Exhibition Place, accompanied by dignitaries including Transportation Minister Prabmeet Sarkaria and Mayor Olivia Chow.
Toronto MP Evan Solomon highlighted the significance of this milestone, referring to it as a definitive step in the project’s progression. “It’s one of those moments when a project moves from promise to proof,” he stated.
Project Details
- Tunnel Depth: The boring machines will operate as deep as 40 metres below the surface.
- Emergence Point: Ontario Line trains will surface at the Don Yard near the Don Valley Parkway and Lakeshore Boulevard.
- Completion Timeline: Target opening is set for the early 2030s, with an updated goal announced for 2031.
- Cost: The current estimated budget for the Ontario Line stands at $29.5 billion, significantly up from the original $10.9 billion.
- Federal Contribution: The federal government will allocate $4 billion towards the project’s expenses.
- Projected Daily Ridership: Approximately 400,000 riders are expected to use the line daily.
- Crowding Relief: The line will decrease congestion by up to 15 percent during peak hours for TTC Line 1.
Station Updates and New Names
Several new station names have been confirmed to better reflect Toronto’s neighborhoods. The renaming includes:
- King-Bathurst Station to King West Station
- Queen-Spadina Station to Chinatown Station
- Corktown Station to Distillery District Station
- Riverside-Leslieville Station to Leslieville Station
Current excavation work for the stations is nearing completion at key locations such as King West, Moss Park, and Distillery District, while work at Chinatown approaches its final stages.
Future Plans for Housing Development
The Ontario government has expressed intentions to integrate housing developments around the Ontario Line. Estimates suggest these changes could lead to the addition of 15,000 new homes in the area, supporting the government’s commitment to building transit-oriented communities.
As tunnelling progresses, officials remain cautious, noting the complexities involved in the construction. Michael Lindsay, CEO of Metrolinx, commented that while the civil infrastructure is meeting its milestones, it does not signal the start of major construction advances.
