Toronto has started tunnelling on its new subway route. The Ontario Line will open up 15 stops between Exhibition Place, west of downtown, and Don Valley Station, which was formerly named Science Centre Station. The project is over 15 kilometres long, with more than half of the line running underground.
“The start of tunnelling is a historic milestone for the Ontario Line which, once complete, will help cut travel times for commuters across Toronto by 40 minutes,” Ford said in a press release.
When will it be completed?
“We think we’re still trending towards the early 2030s to be done with civil infrastructure,” Metrolinx CEO Michael Lindsay said at a press conference in February. After that, the subway line would still need to be tested.
How much will it cost?
Metrolinx declined to give an update on the cost of the Ontario Line. However, a senior government source told Global News in 2024 that the cost of the Ontario Line project alone had increased to $27.2 billion.
How will construction affect traffic?
Beginning Sunday, lanes and sidewalks along the west side of Don Mills Road between Eglinton Avenue East and St. Dennis Drive will close for about five weeks, allowing construction teams to build a new temporary platform. The intersection at Don Mills Road and Gateway Boulevard will be particularly affected through May, as construction starts on a new station

How did construction go on previous transit projects?
The Line 5 budget was originally set at $11 billion in 2007 but it grew by $2 billion over 15 years. In all, the Ontario government spent $13 billion.
