There is room for two failures. The province should have enforced the provincial law, and the feds should not have have taken action through the banking sector.
My preference would be that the fed enforce the laws on the books themselves (if they have the power to do so), or pressure the province to do so (using the democratic leverage available).
There’s no federal police, the government can make their resources available but it’s up to the province to use them or not. And sure, you could use funding, but there’s no guarantee that that would have solved the problem. The province could have kept digging their heels in.
I don't know exactly how Federalism works in Canada but the answer is their jobs. If that doesn't entail stepping in to provincial business, they shouldn't do anything.
Trudeau was the one who triggered the protests in the first place.
The liberal, moral, fast and peaceful solution to the trucker protests was simple: stop forcing people to take experimental drugs against their will. The vaccines didn't reduce transmission, and there is no rule against living life in a risky way (even if you believe the vaccines worked at all), so there was never any moral argument for the mandates. The truckers were right to protest, as Trudeau and the Canadian people were doing them a severe injustice.
Every single vaccine or gathering mandate I experienced was either provincial (Conservatives) or municipal (also conservative for Toronto and georgetown where I live).that they barked up the completely wrong tree is the breathtakingly depressing stupidity behind the whole thing.
Don't believe me? Alberta Conservatives did not have same policies. Then they begged BC and Saskatchewan for ICU beds but that's besides the point - provinces and municipalities had freedom to enact different policies.
Also in Ontario. I am still very confused how none of this seems to have affected Doug Ford. This was the most mandated, school-closed, shut-things-down jurisdiction in North America at the time. And somehow Trudeau is apparently to blame for it all, and Ford is still... electable?
Meanwhile the feds only had jurisdiction over borders and airports. They acquired the vaccines, but it was the provinces that doled them out and set the policies for what would require them.
At the height of covid Ford even had outdoor ski hills shut down. Crazy times. Some of it made sense, some of it didn't. But I can tell you my neighbours with F Trudeau stickers were very angry about the vaccines, but still somehow are voting for Ford. Confusing.
Provincial governments were a mistake - the average Canadian fundamentally misunderstands the division of powers and responsibilities between federal and provincial governments, and this is remarkably useful for bad actors.
I personally think Chrétien was a terrible offender, since his balanced budgets in the 90’s were a result of pushing responsibilities on the provinces. The current wave of conservative provincial governments have similarly created their own problems (particularly with the international student explosion) while placing all of the blame of the federal government.
Harris/Klein + Chretien was a deadly combination, and more intimately connected than people will admit. Supposed ideological opponents, but the latter created the conditions for the former to thrive.
