Within the last two weeks -- the 14-day window believed by scientists to be the incubation period of COVID-19 -- at least 26 flights have arrived in Canadian airports with confirmed cases of the virus onboard.
We still seem to be being pretty lax in dealing with travellers. Some provinces are not even reporting information on air travellers. ie. not calling you and saying, there was a positive case on the flight you flew home on. As long as there are a limited number of travellers, we may be able to contain any clusters but if travel increases we will be back where we started. That's where they all came from originally remember.
