As refurb said, this is completely wrong. Canada is decentralized (yes, including its healthcare system) like the US. Ottawa didn't mandate the Atlantic Bubble (https://en.wikipedia.org/wiki/Atlantic_Bubble), for example; the Atlantic provinces set it up on their own. Ontario's recent lockdown—far stricter than occurred anywhere in the US, as I understand it—is just that, in Ontario.
