Canada DOES have a law that would somewhat have hindered this attack if it were 100% effective, which is limiting rifle magazines to only five rounds.
LMAO are you for real? I can repair a pinned magazine in 30 seconds with a Dremel. The only reason I don't is that unlike murderous terrorists, I obey the law. I am pretty sure that murdering 50 people and wounding another 50 or so might not be 100% legal.
