Cautions accompany Canada’s slow emergence from COVID-19 lockdown
OTTAWA — As Canada slowly emerges from COVID-19 lockdowns, its chief public health officer told the country on Wednesday to temper expectations and continue to take precautions to prevent a resurgence of the illness.
Dr. Theresa Tam’s caution — which included an updated recommendation for Canadians to wear non-medical masks in public — came as Alberta announced more intense screening for international travellers.
Prime Minister Justin Trudeau also struck a tougher tone, saying stricter border controls would likely be needed to prevent long-term economic damage. Alberta Premier Jason Kenney and Trudeau emphasized the need to prevent a second wave of the novel coronavirus in Canada.
The heightened vigilance, Tam said, is necessary to buy time so that a vaccine and other therapies could be found to better curtail the spread of the virus over the coming months.
