Dr. Theresa Tam recommends using non-medical masks when maintaining physical distance might not be possible

Canada's chief public health officer says there has been a social, cultural shift around the wearing of masks during the COVID-19 pandemic.

After first suggesting wearing a mask, Dr. Theresa Tam is now recommending covering your face when maintaining physical distance might not be possible.

She says thinking it of as protecting each other from being exposed to the virus is a key concept for Canadians.

Dr. Tam is again stressing that for summer, outside activities are better than inside and keeping a physical distance and hand washing will continue to be key.
