A little more than a month after pausing the measure, the PHAC announced Thursday it will be re-implementing random testing for fully vaccinated air travellers arriving into the country at four major Canadian airports: Vancouver, Calgary, Montreal and Toronto.

“It is a critical as an early warning system for our public health agency, for healthcare in Canada, and for Covid-19 detection and surveillance.

The mandatory random testing only applies to fully-vaccinated travellers. Unless exempt, unvaccinated travellers will still have to test on days one and eight of their mandatory 14-day quarantine. If a fully-vaccinated traveller tests positive, a 10-day isolation is required, regardless of the province or territory in which the traveller resides.

PHAC´s statement did not explain specific reasons but came as several provinces are presently facing up the seventh wave of Covid-19 and experiencing a speedy increase in cases due to the omicron BA.5 subvariant.
