I live in Canada so am quite aware. If we're talking about comparisons then let's not cherry pick ones without considering the whole context.
Schools have been open for the most part in Ontario and Alberta since Fall 2020.
> Canada has way lower vaccine hesitancy.
New York City has 82.5% of population vaccinated, about as much as Ontario [1]. Yet schools were closed for most parents throughout the pandemic.
> On average Canadians have fewer comorbidities.
Where the hell are you getting this from? Health Canada numbers say 64% adults are overweight or obese [2].

Ontario also had outbreaks that aligned with the removal of lockdown (https://en.wikipedia.org/wiki/COVID-19_pandemic_in_Ontario?w...)
> In early September 2020, the province showed a significant increase in new cases, beginning the second wave of the pandemic.
> From late November to mid-December 2020, the province began placing regions in rolling lockdowns, culminating in a province-wide shutdown beginning Boxing Day
So I'm not sure your use of Ontario is the greatest.
I have families in western Canada and except early Spring and summer of 2020, schools remained open and are still open. They didn’t have much different outcome if not better than us in US.
