With a quick google search, I found this site.
http://www.nationmaster.com/graph/cr...rms-per-capita
I have not tried to verify any to the numbers, but it does not appear to be a site with any particular agenda. It looks more intrested in selling advertising by attracting readers to an encyclopedia service.
Looking at a couple of the statistical compilations they have available showed that the per capita murder rate in the US is nearly three times greater than in Canada, and the the firearm murder rate is nearly five time higher. Another website that I did not cite, because it appears to have an agenda, cited statistics showing a greater possibility of suffering a handgun death in a home where firearms are owned than otherwise. It also showed that the greatest cause of death by firearm is suicide. I suppose a bullet through the head is going to be the last time a suicide victim changes his mind.
