In terms of school closures, it was pretty uniform across Canada, but some provinces reopened schools a bit faster. In Quebec we reopened schools a bit faster than elsewhere. Then again, it wasn't that much faster, so it didn't make a big difference. I know schools in Ontario were closed a bit longer than elsewhere, especially in southern Ontario, where in January 2021 they were closed for a while.
Thinking about it, I love this about Canada. We're able to do different things and learn from each other, and I think we really should try to learn from what we did. The problem is that we don't have data to learn from all of this, because we didn't collect data on kids over the last three years.
Yes, there were some provinces that were marginally better, but there was nothing fantastic.
