A TTC driver was pulled over on the weekend by Toronto police after witnesses reported erratic driving.
The woman was pulled over just before 3 p.m. Friday while she was driving a TTC bus in the city's east end, police in 55 Division told CTV Toronto.
The woman was given a breathalyzer test after she was pulled over on Dawes Road. Police say the woman did not fail the test by blowing over the .08 blood alcohol limit, but alleged the woman registered in the "warning range" which is between .05 and .08.
The woman had her license suspended for 72 hours and has been suspended from work without pay pending an investigation by TTC management and the union. She will also face a disciplanary hearing which will decide if she should be fired.
"We are continuing the investigation but obviously we expect to have operators report (for work) fit for duty," said TTC Chair Adam Giambrone in a written statement to the media Tuesday morning.
The incident comes in the midst of a public relations blitz by the TTC to improve relations with public transit commuters.
Community consultations are being held throughout the Greater Toronto Area to give TTC officials a chance to listen to public complaints.
On Tuesday, TTC riders said they were shocked to hear about the latest allegations.
"They are carrying so many people around," said one woman waiting for the bus. "We're in their hands."
Another rider said she was "disgusted" by the news.
"It's a job," she said. "You would think there's more expectations and more accountability on that end."
Public disapproval came to a head in January after a TTC ticket collector was photographed taking a nap on the job.
Tensions continued to boil between TTC staffers and riders after a commuter took a video of a bus driver taking an unscheduled break during his route.
