It's a hot topic why I'm not ordering a requirement to wear #masks at this time. To be clear, in alignment with @WHO, @PHAC_GC, & @CPHO_Canada, I absolutely recommend we wear #FaceCoverings when we can't keep 2 m #PhysicalDistancing. Here are 3 reasons why I don't require it: 1/8
1. Enforcement. A public health order requires a court filing and an appearance before a judge every time one wishes to enforce it on a person/business. An order would be basically unenforceable. If we don't enforce, it's effectively just a recommendation (already done that). 2/8
2. Strength of science. While science increasingly supports #facecoverings are likely effective at slowing #COVID19 spread, research is still weak. E.g. @TheLancet systematic review finds much potential benefit, but only “low certainty” that effective. thelancet.com/journals/lance… 3/8
