Mayor John Tory has accepted a challenge from a disgruntled subway rider who says that the temperatures on non-air-conditioned subway cars are literally too hot to handle.

Tory’s office has confirmed that the mayor will take a ride with transit user Bianca Spence on the entire stretch of Line 2 in an un-air-conditioned subway car sometime soon to feel the heat for himself.

Spence first issued the challenge to Tory in a July 14 tweet.

“I hereby challenge @JohnTory to ride Line 2 in a train with no A/C from Kennedy to Kipling. I'm serious,” she wrote.

Since then she has repeated the challenge in a number of tweets, sometimes as the city sat under heat warnings because of soaring temperatures.

The TTC has been grappling with the loss of air conditioning on a number of older subway cars running on Line 2 this summer. The transit agency has said that less than 20 per cent of cars on the line are affected and has encouraged customers who have trouble with the heat to switch cars at a subway stop or wait for the next train.

“The TTC is aware of this problem and has a program in place to fix air conditioning units as quickly as possible when they fail,” the TTC says on its website.

However that has not satisfied many customers who have been riding the line this summer amid record-breaking hot temperatures.

Speaking with reporters Monday, Tory acknowledged that riders are frustrated and said he’d like to see the air conditioning units fixed more quickly on the affected cars.

“I’m not happy with a status quo that has had us take as long as has been taken to get all of the cars fixed in terms of their air conditioning,” Tory said in a scrum.

Tory said it has taken roughly four days per car to fix the air conditioning problem.

“Of course that means it has taken the entire summer so that the work on completing the air conditioning repairs will be done just about the time it starts to turn cool and I don’t accept that,” Tory said.

Tory’s office said the ride on the un-air-conditioned car from Kennedy Station to Kipling Station has not yet been scheduled.
