Crews break ground on Ontario Line launch shaft

Key Takeaways:

• Excavation has begun on a 16-metre-deep launch shaft at Exhibition Station, which will serve as the starting point for tunnel boring machines digging six kilometers eastward. The Ontario Line subway is a major part of Ontario’s largest-ever subway expansion project.
• Once completed, the Ontario Line will provide over 40 connections to other transit services, significantly reducing travel times—for example, cutting a cross-city trip from Exhibition Place to Don Mills Road from 70 minutes to under 30 minutes.
• The Ontario Line is part of the Transportation Plan for the Greater Golden Horseshoe.

The Whole Story:

The Ontario government has officially started excavating the launch shaft for the Ontario Line subway tunnels at Exhibition Station.

“It’s been more than 60 years since the first subway tunnels were built in downtown Toronto,” said Prabmeet Sarkaria, Minister of Transportation. “Under the leadership of Premier Ford, we’re getting the Ontario Line done to tackle gridlock and increase access to fast, reliable and affordable transit for millions of people across the GTA.”

The 16-metre-deep launch shaft will be the starting point for two tunnel boring machines that will dig six kilometres east, from Exhibition Station to the Don Yard, west of the Don River. Once tunnelling is complete, the launch shaft will be repurposed as a tunnel portal where Ontario Line trains will transition from above to below ground.

“The Ontario Line subway is part of one of the biggest partnerships to construct public transportation in Canadian history,” said the Honourable Ahmed Hussen, Minister of International Development, on behalf of the Honourable Sean Fraser, Minister of Housing, Infrastructure and Communities. “Work is progressing and today’s groundbreaking is another step toward affordable, reliable and quick public transit for Torontonians.”

Exhibition Station will be a vital transit hub, serving both the future subway and existing GO rail customers. A trip across the city from Exhibition Place to the Eglinton Crosstown LRT at Don Mills Road will take 30 minutes or less compared to the hour and 10 minutes it takes today. The Ontario Line will offer more than 40 connections to other subway, bus, streetcar and regional train services, bringing hundreds of thousands more people within walking distance of transit.

As part of the Transportation Plan for the Greater Golden Horseshoe, the government is delivering Ontario’s priority transit projects, which include the largest subway expansion in Canadian history – the Ontario Line, the Scarborough Subway Extension, the Eglinton Crosstown West Extension and the Yonge North Subway Extension.
