Mississauga mayoral candidate Bonnie Crombie is pledging to make a western extension of the TTC’s Line 2 subway into the city a priority, unveiling additional details surrounding her push to begin work toward a direct connection between Toronto’s subway network and the city centre.

Under the proposal, Crombie said she would work with the province, Metrolinx, the City of Toronto and the TTC to develop a joint business case for extending Line 2 west from Kipling Station through the Sherway Gardens area and into the heart of Mississauga.

The plan does not include a construction timeline or cost estimate. Instead, it focuses on advancing the planning required to determine whether the project is feasible and how it could be delivered.

If elected mayor, Crombie said she would convene meetings with government and transit partners within her first 100 days in office and seek federal participation in the planning process.

She also pledged to bring a motion before council within the same timeframe to formally launch Mississauga’s participation in a business case study and identify funding for the city’s share of planning work.

The plan

According to the proposal, the study would examine potential routes and station locations, including options serving Sherway Gardens and Mississauga City Centre. It would also assess connections to the Hazel McCallion Line, GO Transit, MiWay and the Mississauga Transitway.

Other areas of study would include projected ridership, travel-time savings, accessibility, housing and employment growth opportunities near stations, construction and operating costs, environmental impacts and requirements for integrating the extension with the TTC’s existing Line 2 network.

Crombie said she wants the jointly funded study underway within the first year of her term, with a goal of completing the initial business case within two years.

A key element of the proposal is a commitment to evaluate elevated sections along parts of the route rather than relying entirely on underground tunnelling.

Other transit projects to be prioritized

Crombie said the business case would compare elevated construction, tunnelling and hybrid options, examining factors such as project costs, construction timelines, service reliability, noise and impacts on surrounding communities.

The mayoral candidate also said a future funding and delivery agreement would need to determine which government or agency would lead the project, how costs would be shared and who would ultimately own, operate and maintain the extension.

While pursuing the subway proposal, Crombie said she would continue advocating for other transit improvements, including better bus service, completion of the Hazel McCallion Line and all-day, two-way GO Transit service on the GO Transit Milton train line.

The plan calls for regular public reporting on the project’s progress, including updates on spending, funding commitments and major decisions as planning work continues.

Reaction to push for subway extension

Three of the leading mayoral candidates in Mississauga were skeptical about the proposal to extend Line 2 to Square One from Etobicoke on Tuesday when asked about the issue.

Dipika Damerla said the proposal is “so hypothetical” that it was “kind of hard to comment,” adding she wouldn’t object if the provincial government wanted to proceed with such an initiative.

“The real gap right now is along Lakeshore, where we are building a city, the town (the size) of Collingwood,” she said while calling for the Ontario government to build two new GO Transit Lakeshore West stations in the city to accommodate demand.

Carolyn Parrish echoed the call for overhauling service on GO’s Milton line to help the west end of Mississauga. She said she doesn’t think the subway extension is a good idea, citing the potential multi-billion-dollar cost. Parrish said while she awaits the completion of the Hazel McCallion LRT by the private-sector consortium hired by the province, she has been looking at ways to use micro transit buses to expand transit service.

Alvin Tedjo said if he is elected, he wants to proceed with his plan to add five new bus rapid transit routes by the end of his term to help expedite bus travel. He also supported additional Milton line service.

“[Crombie has] had 10 years to propose this $20-billion plan that’ll take 20 years to build that really doesn’t have a realistic chance of getting supported and funded by this provincial government,” Tedjo said.

CityNews contacted representatives for Ontario Premier Doug Ford and Transportation Minister Prabmeet Sarkaria Tuesday morning to ask about the proposal and if it was being considered, but a response wasn’t received as of Tuesday evening.

Crombie said she hasn’t spoken with Ford nor City of Toronto and TTC officials about the proposal in the absence of a mandate, but added she hasn’t heard negative feedback from the Province. She said spoke with engineers who estimated the cost could be $700 million a kilometre — down from recent instances where costs have hit nearly $1 billion a kilometre.

“We have a premier who loves to build subways and I agree with him. It’s time that Mississauga has subway stops. We are larger than the city of Vaughan. Vaughan has subways. Markham and Richmond Hill are getting them, so is Scarborough,” Crombie said.

“We are moving forward with feasibility study to understand exactly, examine the routes, the cost, the ridership, etc. We will do a full business case before we proceed and present it to the Province for consideration for funding.”

Matti Siemiatycki heads up the University of Toronto’s Infrastructure Institute. When asked about the pitch for extending Line 2 potentially by several kilometres, he said a lot more study is needed to determine the need.

“We’re in the magic marker phase of this election when it comes to transit proposals. People are drawing lines on all sorts of maps and maps that actually aren’t even theirs to fund,” Siemiatycki told CityNews.

“Ideas generated during an election are good, but they can often distract from the more detailed necessary work of making sure that maintenance is being done on the local transit system and really setting priorities for transportation in a municipality.

“This provincial government has picked up on campaign promises and other priorities in the past, so it’s not out of the question. But it’s definitely not a slam dunk, depending on who gets elected.”

Meanwhile, Mississauga’s election will be held on Monday.
