Is it a bad idea to look at how other people, companies, states, countries do things to see if perhaps what is done by you, your company, your state or country could be improved?
Now lets look at the overall arguement
Canada and the US both regulate food and auto's for safety, some differences, and both are generally safe for people to eat, or be around in the case of cars. I expect overall death rates for Canadians and Americans when it comes to food and cars are generally the same
Canada has stricter gun regulations. You can get rifles and shotguns, go hunting with them without too much of an issue. Just get a license/permit requiring a fairly easy background check and pass a firearms course. There are restrictions on magazine size however, and if wanted you can get a tacticool AR15 with all the toys.
Handguns are more difficult, requiring a background check (that is actually checked) before being able to purchase one legally. The use of a handgun is quite restricted however, the carrying of one is generally limited to between your home and the gun range. When travelling with one it has to be in a locked case, and you have to take with you your approved route to the gun range. So stopping at Costco on the way home or to the range can get you in trouble.
Canada does have gun deaths and murders from guns, we have gangs in our cities (some of our smaller cities in Sask have very serious gang issues) but our overall violence from guns is much lower. Canadian culture is probably the most similar to that of the US. So comparing Can culture to that of the US is the most apt, if discussing cultural aspects of why gun violence.
So why not look at what make Canada's gun violence rate so much lower than that of the US, as a possible means to address the issue of gun violence in the US
