The TTC has unveiled new details about its $1.5 billion overhaul of Bloor-Yonge Station, including a plan to install platform edge doors along the Line 1 subway platform.

The detail was included in a wider update, outlining some of the work planned for the downtown subway station.

The TTC also shared a number of new renderings in the post.

“It is a great new development that we will be adding those platform edge doors to the northbound and southbound platforms on Line 1 and we are also going to make Line 2 platforms ready for platform edge doors so once the Automatic Train Control is finished on Line 2 – it has already been completed on Line 1 – we will have those platform edge doors pn both Line 1 and 2 at Bloor-Yonge Station,” Chris Joseph, the TTC’s manager of community and stakeholder relations, told CP24 on Friday afternoon.

Transit advocates, including the group TTCRiders, have long called for the installation of platform-edge across the TTC in order to improve safety.

Several mayoral candidates have also said that the TTC needs to act now to install platform-edge doors in at least some stations.

The cost, however, has been a roadblock so far.

While the project was included in the TTC’s 15-year capital plan in January its estimated $2.86 billion price tag still remains entirely unfunded.

“As with everything, retrofitting a system that is aging, and that's already built and that's in use is much more expensive and much more complicated than trying to build something in a system that's being built from scratch,” Matti Siemiatycki, the director of the Infrastructure Institute at the University of Toronto, told CP24 in April. “So the question, I guess, is one of feasibility and one of costs and priority.”

As part of its overhaul of Bloor-Yonge Station, the TTC is planning to build a new dedicated platform for eastbound passengers on Line 2 and expand the existing platforms utilized for Line 1.

It is also planning to build a new exit to Bloor Street and replace the existing escalators, elevators and stairs.

"It is going to be a completely new station that is going to be renovated top to bottom," Jones said. "It is going to look modern, bright and will also have improved accessibility which is really important."

Major construction is expected to begin in late 2024 and wrap up sometime in 2031, according to the TTC.
