The Public Health Agency of Canada does not recommend that healthy people wear masks as they go about their daily lives in the community.
There is no evidence to suggest that wearing masks will prevent the spread of infection in the general population. Improper use of masks may in fact increase the risk of infection. Masks do not act as an effective barrier against disease when they are worn for extended periods of time. In addition, removing your mask incorrectly can spread virus to your hands and face.
