The federal government has imposed travel restrictions for foreign nationals entering Canada by air. But an order in council in late March extended a number of exceptions from the ban — 19 of them, in fact. They include temporary foreign workers, foreign students and family members of Canadian citizens or permanent residents.
There are also likely to be a number of travellers who are in transit to other countries — again CBSA does not break out the number.
But it is entirely possible we are continuing to import the disease.
The question about a lockdown that is not a lockdown is particularly relevant as restrictions start to ease. Transmission of COVID-19 from travellers and those exposed to travellers constituted more than 90 per cent of cases in mid-March, before community transmission took hold.
