My personal opinion is that if you make guns easily accessible to unstable young people especially unstable young men - they end up acting on impulses that otherwise they wouldn’t be able to and hence we get the constant shooting sprees

The mental health issues would still be there but it would be more difficult to act on those impulses without access to guns.

And all honesty, it's the easy access to assault weapons more than anything. It isn't impossible in Canada to get a single shot hunting rifle, but the fact that it usually stops there is a big reason they don't have mass shootings at comparable levels to America.
