Canada already has good gun control. We've had it for decades. Very, very few lawful gun owners commit crimes with their guns.
The last government has been great at announcing ever longer lists of guns to ban but has yet to seize a single one. The list gets longer, the date it takes effect keeps getting pushed out too.
Focus on the source of guns used in crimes: our neighbors to the south. Performative bans of experimental guns and historic rifles makes no one safer.
