Canada's largest airport has seen a number of COVID-19 cases this month, both among passengers and staff.

Fifty-five flights with infected passengers on board passed through Toronto's Pearson Airport in the past two weeks.

Pearson also confirmed that pre-board screening officers tested positive for the disease in October.

2 Pearson Screening officers with covid-19 in October

The officers tested positive on October 3 and 12. The last time they were at the airport was on September 27 and October 10.

Three other Pearson employees have also contracted the virus this month — two in general operations and one employee of Chart Right, a private charter company.

Pearson has a voluntary airport-wide case log that records cases anonymously among workers.

The case log does not specify whether these employees are self-isolating at home.

Pearson has been ramping up its cleaning protocols in recent months.

The airport recently unveiled machines that wipe germs from your devices in seconds.

Sanitization at the airport occurs every two hours and a passenger disinfection corridor is currently being tested.
