So...1 in 24 Canadians has Covid, XBB1.5 (kraken) variant is projected to be at 22% in Ontario by the end of the week, people are still dying of Covid (279 in Canada in the first week of January), and though voluntary mask wearing is low, 69% of Canadians support mask mandates if necessary.

Public health in many regions recommends or strongly recommends mask wearing.

But no mask mandates?
Not even in education and the workplace?
Nothing?

Mandates would make it so much easier for the caring majority to normalize wearing a mask again. Many people understandably don't want to unless it is clearly necessary. are necessary to get mask wearing in public up to >80%, which IHME estimates would halve deaths from covid with a month.

In the absence of clear direction from public health, and protect yourself and those around you as best you can.
