Canada has the same rates of gun ownership as America and you don't see cops come up with guns blazing like they do here
Let’s bring data:
Civilian firearms per 100 people: - US = 120.5 vs Canada = 34.7
Share of adults with guns: - US = 32% vs Canada = 19%
Share who CARRY a gun: - US = 26% of handgun owners carry all the time and 32% most of the time vs Canada = almost nobody carries

If Canada is like New Zealand, which also has a similarly high rate of gun ownership - it's largely different types of guns - that is, guns for hunting, not for killing people - very hard to conceal a rifle or shotgun compared to a pistol.
