Some provinces there literally have curfews and police patrolling the street to arrest anyone breaching curfew. Just because it's justified as an attempt to slow the spread ot covid, doesn't make it any less totalitarian.
Temporary emergency measures don't make a totalitarian government. For that matter, similar measures were temporarily taken and then rescinded in the past; proof of non-totalitarianism. Further proof is minority governments and recent changes in governing parties. Totalitarian governments don't have these.
I think further burden of proof on wether Canada is a totalitarian state reasonably falls on those who believe it is. It seems reasonable to accept that Canada isn't totalitarian as a premise, when I say that some restrictions on freedom of speech don't inevitably lead to totalitarianism.
