Canada's top doctor says non-medical masks can help stop the spread of COVID-19

Canada's chief public health officer now says that wearing a non-medical mask can help stop the spread of COVID-19.

Dr. Theresa Tam, the top doctor at the Public Health Agency of Canada, said today that Canadians can use non-medical masks in tandem with social distancing measures to limit the transmission of the deadly virus when out grocery shopping or at a pharmacy.

The recommendation represents an about-face for the public health officer — who until now has resisted the idea of non-health care professionals wearing masks.

"Wearing a non-medical mask is an additional measure that you can take to protect others around you," Tam said — while warning that a non-medical mask doesn't necessarily protect the person wearing it.

"A non-medical mask can reduce the chance of your respiratory droplets coming into contact with others or landing on surfaces," Tam said.
