The next bill can ban more, fix the bugs, etc, but the flag has been planted: there's no room for those weapons in Canada.
A huge number of people have wanted to ban weapons like these since Ecole Polytechnique [1] -- and probably much further back. We've been lucky to have few enough such mass murders to remember many by name, and it also makes them horrifying enough that we're not going to sit back and pray the crime away. The Liberal Party (currently in power) ran on banning these weapons. Then they banned the weapons. They did the job they were elected to do.
I don't think that's a good example tbh.
[edit] Let's be super clear when you say "pushed through by a minority government during a pandemic" -- you're seeming to imply that the minority is somehow strong-arming the majority. That's the exact opposite of how that works in the Canadian parliamentary democratic system. A minority government is in a very weak position and can be removed at any time. If this was at all controversial the next confidence motion would be swiftly defeated and the government would fall. A minority government wouldn't do something like this without absolute confidence.
Unlike a majority government a minority government must rule by consensus or face immediate removal. I think they normally don’t even make it past the 3 year mark.
