Of the 8.6 Million Arrived in Canada, Only a Small Portion Actially Reuquired to Quarantine While Exempted Are Not Being Tested at Border: Canada's Covid Bungle

"...But there were still 8.6 million arrivals total (land and air) between then and the end of January 2021, and 74 per cent of them — about 6.2 million — were exempt from the previous requirement to isolate at home for 14 days, according to Canada Border Services Agency (CBSA) statistics.

...The National Post first asked the Public Health Agency on Feb. 1 for data on the number of coronavirus cases identified among international travellers exempted from quarantine versus the minority actually required to isolate. The agency had yet to provide that information by deadline Tuesday.

Dr. Jeff Kwong, a University of Toronto public health professor, said he simply doesn’t know how much of a problem the exempted travellers pose.

But even if it’s impractical to force them to quarantine, it would likely make sense to use some of the 38 million rapid COVID tests obtained by the federal government to screen truck drivers and others, he said.

“Why aren’t we doing testing of them every time they cross into Canada?” asked Kwong. “Every time they cross into (Canada), maybe they could get a rapid test. Then they’d know if they are safe to go home to their families.”
