Canada has seen nearly a 30-percent drop in active COVID-19 cases over the past two weeks, but chief public health officer says strict measures should remain in place as more contagious variants of the virus threaten to derail this downward trend.
In a daily update Thursday, Dr. Theresa Tam said there are 48,221 active COVID-19 cases in Canada, down from more than 68,400 cases two weeks ago.
