Those restrictions didn’t do anything because they targeted the groups of guns and owners who aren’t actually being used in crime or shooting people.

There are sane things you can do that actually help, like requiring safety courses and having regular background checks. Canada already does this and the Conservatives didn’t touch this.

Then there are things which arguably do not increase safety but do increase burdens on gun owners and society, like forcing people to register bolt-action hunting rifles (used very rarely in crime), or secure an ATT (Authorization To Transport) every time you want to move a gun literally anywhere, including to hunt or shoot at the range. These are the things the Conservatives changed to make less overbearing because no one could prove they actually help and they were costing a great deal of money. Fun fact: restricted guns are still registered in Canada, and that includes nearly all legal handguns.
