The TTC workers’ union says a bus driver fired for running a red light and almost hitting a pedestrian last week should be reinstated.

A dashboard camera video posted on YouTube shows a TTC bus driving through an intersection 15 seconds after the light turned red. A middle-aged man crossing the street speeds up to avoid being hit and looks back in disbelief. Other drivers honk at the bus.

The incident occurred at midday on Oct. 21 at Lake Shore Blvd. W. and Superior Ave. in Etobicoke.

“The reality is, is you’ve got human being in operation. And when you work in the industry that we do with the long-hour days that we have and the repetition that we have — and I’m not making excuses . . . mistakes will occur,” said Bob Kinnear, president of the Amalgamated Transit Union.

Kinnear said the TTC fired the driver and the union and the TTC are currently involved in a grievance procedure.

“He’s in the process but there’s been no conclusion to what the actual discipline will be,” he said, adding that he hopes the issue will be resolved in a week or so.

TTC spokesman Brad Ross, however, stated in an email that he didn’t believe the driver had been fired, though the transit commission launched an internal investigation after the video was submitted as part of a complaint last week.

Kinnear said he wants the driver back at work. He said it’s evident from the video there was an infraction but added any person can have a “mental lapse.”

Ross would not provide details of the disciplinary action, saying that comments could jeopardize a possible future arbitration hearing, but he called the incident an “obvious and preventable” violation of the Highway Traffic Act and a “blatant violation” of the red light.

In July, a rookie TTC bus driver was fired after she ran a red light and swerved to avoid hitting a pedestrian. The incident was also caught on a dash cam.

Const. Victor Kwong said Toronto police don’t normally initiate investigations based on dash cam footage. A video alone is not usually enough for a probable conviction, he said.

“There’s so many different things that aren’t visible in a video,” such as whether a sign is obstructed and whether the driver made an attempt to stop, he said.
