Ontario Premier Doug Ford says building a 50-kilometre tunnel, one of the longest in the world, under Highway 401 would relieve gridlock for the Greater Toronto Area.
Ford announced the plan to complete a feasibility study for the project at a news conference in September.
Construction industry leaders applaud the premier for the plan because it will boost employment.
“This will boost thousands of construction jobs for LiUNA members and skilled trades workers while building resilient infrastructure to meet the growth, connectivity and, if feasible, provide innovative solutions to our transit infrastructure,” said Victoria Mancinelli, a spokeswoman for the Labourers’ International Union of North America, Canada, which represents about 70,000 construction workers in Ontario.
No cost estimates or timeline was provided for the project.
“This is something we are going to get done,” Ford said, noting LiUNA has a training centre for tunnel construction training. “We have the skillset. We have the skilled trades right here ready to go. We have great unions like LiUNA and the carpenters and the plumbers and everyone else that is excited about this project.
“We’re tunneling experts now. We’ve tunnelled kilometres and kilometres of subways.”
The 401 tunnel could stretch from Mississauga in the west to Markham in the east. Calling it a visionary project, the premier said the new infrastructure would last decades.
The Ontario Sewer and Watermain Construction Association (OSWCA) is supporting Doug Ford and the government of Ontario’s decision to provide relief for commuters in the Greater Toronto and Hamilton Area (GTHA) with the launch of a technical evaluation for the proposed transportation tunnel expressway under Highway 401.
“Today’s announcement is a part of the Ford Government’s ambitious plan to build Ontario,” said Patrick McManus, executive director of the OSWCA. “The proposed transportation tunnel expressway under Highway 401 will create thousands of good paying jobs and will help get people and goods moving faster across the busiest transportation corridor in North America.”
The Residential and Civil Construction Alliance of Ontario (RCCAO) is also on board, calling the tunnel proposal an innovative approach to transportation infrastructure.
“Congestion in our region isn’t just a nuisance—it’s a crisis impacting businesses, people’s daily lives, and their health and well being,” said Nadia Todorova, Executive Director of RCCAO. “Other jurisdictions regularly use tunneling technology to address similar challenges.
“This expressway proposal shows that Ontario is ready to be proactive and innovative in finding solutions that benefit everyone.”
RCCAO will support the government throughout the feasibility study, bringing the expertise and technical knowledge of its members to the table.
“We will collaborate with the government to ensure this project is executed efficiently and achieves its intended goals,” Todorova said. “RCCAO has long advocated for infrastructure solutions that address the needs of today while anticipating the challenges of tomorrow.”
The GTHA loses about $11 billion annually due to gridlock.
While supporting the exploration of a transportation tunnel under Highway 401, a model that has shown to be successful in other jurisdictions, construction industry leaders are warning that investments to rehabilitate and expand much-needed water and wastewater infrastructure are also critical to account for the rapid population growth in the GTHA.
“For decades, we have neglected building the critical transportation and highway infrastructure needed to address Ontario’s growing population,” said Stephanie Bellotto, manager of government relations. “We are pleased to see that the Ford Government has a bold vision for tackling traffic congestion, which is already costing the GTHA $11 billion per year in lost economic opportunity and is continuing to deliver on critical infrastructure projects such as Highway 413 and the Bradford Bypass.”
