Nothing worse than most other administrations in Canadian history (some scandals, some corruption, nothing that I would consider unusual or extreme). Some people are salty because, like most politicians, Trudeau didn’t deliver on all of his campaign promises.
The thing is, Prime Ministers (and Premiers) seldom stay in power for more than two consecutive terms in Canada. That’s when voters seem to insist on going to look for a new magic wand to fix things (never mind that it’s never worked in the past).
In the end, it’s all a popularity and media manipulation contest.
