Dr. Theresa Tam, Canada's Chief Public Health Officer, has issued advice on the wearing of masks outdoors.
"You asked: Should I wear a mask when I’m jogging or walking outdoors?" her Tweet begins. "#MaskOn when you’re active outdoors in areas where #PhysicalDistancing is hard to maintain. Tip: Choose routes that make it easy to keep your distance from others."
The CDC recently said it OK for Americans to not wear masks outdoors provided they are vaccinated and not in a large crowd.
President Biden, who is vaccinated, has continued to wear his mask outdoors, calling it a "patriotic responsibility" to do so.
