TORONTO -- Three TTC employees all working out of different divisions received positive COVID-19 tests on Wednesday.

All three cases were confirmed by ATU Local 113, the union representing nearly 12,000 public transit workers in Toronto and York Region.

The first of the three employees is a Toronto bus operator who came into work for one hour on Wednesday and tested positive for COVID-19 the same day.

“We received unfortunate news today that an ATU Local 113 member, a bus operator at Arrow Road Division, has tested positive for the coronavirus (COVID-19),” ATU Local 113 President Carlos Santos said in a statement.

“I spoke with the member who is recovering at home. On behalf of all ATU Local 113 members, we wish them a quick and full recovery.”

The employee’s last shift was on Sept. 23 from 10:15 a.m. to 11:15 a.m. The union said they received the positive test result the same day.

It is not clear when the employee received the diagnosis.

A spokesperson for the Toronto Transit Commission said that the agency is cooperating with Toronto Public Health. They did not say what route the employee was working either in the lead up to the test result or on the day that he received the diagnosis.

“(Public health) will determine next steps with respect to potential risk or exposure as well as advice for any known contacts,” spokesperson Stuart Green said in a statement.

Green said he couldn’t provide more details due to “privacy and personnel matters.” However, he stressed that employees must self-isolate if they are waiting for results after being tested for COVID-19 because they are experiencing symptoms, have been in close contact with a positive COVID-19 individual or have been contacted by health officials.

ATU also confirmed on Wednesday that a customer service agent tested positive for the disease. That employee last worked on Sept. 15 and received their test results on Sept. 23

The final case was a general body repairman at Harvey Shop, located near Bathurst and Dupont streets.

“The member’s last shift was on Thursday, September 17 and received a positive test result on Wednesday, September 23,” Santos said. “Please practice physical distancing as much as possible before, during and after your shifts – and stay home if you feel unwell.”

According to the ATU, there have been 70 members and 13 other TTC employees who have tested positive for COVID-19
