Canadian here. I've come to say that I have no problem with this. Specifically:

• Taking away the firearms licenses of those involved in acts of domestic violence or criminal harassment, such as stalking - No argument here
• Requiring long-gun magazines to be permanently altered so they can never hold more than five rounds - They're already not allowed to hold more than 5, but all they do now is put an easily removable screw in the higher capacity magazines so it stops people from loading more. The new legislation looks like it will only allow mags that can't be altered.
• The freeze on handgun ownership looks like it is aimed at people not being able to buy a gun and sell it to an unlicensed owner. Not sure how much of that it a problem, as most of the criminal guns in Canada seem to be smuggled in from the US. Also, it's worth noting that if you own a handgun, it has to be stored in a safe at a gun club. I don't think you're allowed to keep it at home.
• The buyback looks like it is for AR-style weapons, which have already been banned.

I know other Canadians here will disagree with my opinions, and more power to you. I was the first in line to register my rifle when there was a long gun registry, and I'd do it again. As the article says, in Canada gun ownership is a privilege, not a right.
