If more guns make you safer, then the US should be the safest country on earth yet last year there were 12,236 deaths and a further 24,755 injuries from shootings(3.53 per 100,000). This casualty toll includes 640 children aged 0-11 killed or injured by guns.
Canada has outstandingly low gun casualty statistics. In 2009, there were 0.5 deaths per 100,000 from gun homicide — only 173 people. Still, the ownership is comparatively high — there are 23.8 firearms per 100 people in the country.
There is no legal right to possess arms in Canada. It takes sixty days to buy a gun there, and there is mandatory licensing for gun owners. Gun owners pursuing a license must have third-party references, take a safety training course and pass a background check with a focus on mental, criminal and addiction histories.
Licensing agents are required to advise an applicant's spouse or next-of-kin prior to granting a license, and licenses are denied to applicants with any past history of domestic violence. Buyers in private sales of weapons must pass official background checks.
Canadian civilians aren't allowed to possess automatic weapons, handguns with a barrel shorter than 10.5 cm or any modified handgun, rifle or shotgun. Most semi-automatic assault weapons are also banned. As a result of exemptions, several kinds of assault weapons are still legal in Canada, although this has been the source of some controversy.
You would think there would be more crime in Canada as almost no one carries a concealed weapon yet the per capita rate of all crimes is much lower than the US
