VANCOUVER -- Three screening officers have tested positive for COVID-19 at Vancouver International Airport, the Canadian Air Transport Security Authority has confirmed.

CATSA did not say when the employees tested positive, but said there are more than 700 screening officers working at the airport.

"CATSA's priority is the well-being of screening officers and those working in and travelling through Canadian airports while offering the highest levels of security to the travelling public," CATSA media spokesperson told CTV News Vancouver in an emailed statement.

"There has been no impact on our screening operations."

CATSA says the screening officers are employed by a third-party company, G4S Secure Solutions.

In an emailed statement, G4S Canada confirmed three of its officers tested positive.

"In accordance with guidance from local health authorities, G4S also confirms that the proper quarantine and reporting policies have been followed. G4S management is in constant contact with the three employees to monitor their health," a spokesperson said.
