An OC Transpo bus driver who tested positive for COVID-19 may have driven for two days after they first experienced symptoms of the virus, according to a city memo released Thursday.

The employee's last day at work was March 31, according to the memo sent to members of city council and the transit committee by John Manconi, the city's general manager of transportation services.

The driver called in sick April 1 and has not returned to work, Manconi said. On Wednesday, the driver was tested for the coronavirus and the results were confirmed Thursday.

Ottawa Public Health (OPH) is looking for all possible contacts of the driver.

The key period, OPH said, is the two days before the employee showed symptoms, along with the days after they became ill.

"The operator may have first showed symptoms on March 29," Manconi said in the memo.

The driver worked March 27, as well as two dates after possibly having symptoms, on March 30 and March 31. The driver was off March 28 and 29.

If a rider has concerns about exposure, the city says they can contact OPH at 613-580-6744 and speak to a public health nurse.

"OC Transpo is identifying vehicles and facilities that may require additional cleaning above our enhanced cleaning process," noted Manconi.

This is the second OC Transpo driver who has tested positive. OC Transpo reported April 1 a driver who had already been in self-isolation had tests confirm COVID-19.
