TWEETED: Ottawa Public Health explains the change in face covering policy

In the days of late winter and early spring Ottawa Public Health and other health officials in Canada were saying face masks were not a necessity in the fight against COVID-19.

In the early summer, things changed and the message essentially became “face coverings are a good idea.” Now, in July, the policy has changed with a new order for mandatory face coverings at indoor public spaces. With many questions on why the policy has shifted, Ottawa Public Health took to Twitter to explain the reasoning. You can read their Twitter thread here or by clicking the tweet below.

THREAD: MANDATORY MASKS. Please read

Public Health is about following evidence, so when we call for change, that change is the result of what our evidence is telling us. Lately evidence has been coming at great speed & volume. We've been doing our best to keep you informed (1/7)
