A TTC guard employee has been fired and is being blamed for the door being left open on a moving TTC subway car, according to TTC union head Bob Kinnear.

A passenger recorded the harrowing ride over the Bloor Viaduct as the subway travelled on the Bloor-Danforth line with the door completely open on May 27.

The firing comes as the results of an investigation into the incident are being presented to the TTC board Tuesday afternoon.

TTC spokesperson Brad Ross said the door was not a mechanical issue, but rather the fault of the TTC guard for leaving the station with the door open.

According to Kamal Javed, who shot the video on the train, a TTC employee attempted to fix the problem but after a few minutes he left. Then the train started moving towards the next station.

“We thought he’s coming back but the train literally left the station with the door open,” Javed told CityNews on Saturday.

“Everybody was saying ‘oh my God, what’s going on, why they are moving the train?’”

Subway trains cannot start driving unless a green light is on and in this case, the guard would have had to take the door offline but didn’t close the barricade before leaving the station, Ross said.

“When a door is taken off line the driver gets a green light in his operator booth to proceed,” Ross said. “He had no way of knowing that the door was left open.

“Everything told the operator it was safe to proceed.”

Kinnear told CityNews the union is planning to fight the firing of the employee.

The train was taken out of service to be looked over by mechanics and according to Ross they didn’t find any issues with it.
