The driver worked four routes for four days, from March 10 to 13, the city said.
The routes include 11 Steeles, 51 Hereford, 53 Ray Lawson and 57 Charolais.
The driver reportedly told the city about testing positive on Tuesday evening. The operator is self-isolating at home for the next 14 days, the city said.
“Peel Public Health indicates there is no additional risk to the riders on the transit bus than there would be in the general community,” city officials said in a statement, adding that employees who were in close contact with the operator are being told to self-isolate.
“People on the buses in review on the above days who are feeling well, with no symptoms, should continue to go about their daily routines and not call public health. If you develop symptoms, please call Peel Public Health.”
The city said enhanced cleaning and disinfecting still remains in effect. The cleaning and disinfecting of all hard surfaces, operator compartments and seats was previously scheduled for every 48 hours but has now been increased to every 24 hours.
Only half of the seating capacity is allowed on Brampton Transit buses, city officials said, and the transit service is also taking additional measures, such as rear-door boarding and allowing passengers to ride for free.
