We, in Canada, also count simple assault (slapping, spitting, pushing, etc, which result in no serious bodily harm) where the US does not. From the US wiki article:
"The reported US violent crime rate includes murder, rape and sexual assault, robbery, and assault, whereas the Canadian violent crime rate includes all categories of assault, including Assault level 1 (i.e., assault not using a weapon and not resulting in serious bodily harm). A Canadian government study concluded that direct comparison of the 2 countries' violent crime totals or rates was "inappropriate"."
From the articles you linked to, it looks as though Ontario has the lowest rate of violent crime (900/100K residents) with Nunavut as the highest (10K/100K) with an overall rate of 1100/100K. Again, these rates include all forms of assault, not just ones that cause injury like the US does. The US has an overall rate of 386/100K, but does not include simple assault nor sexual assault in that total. Looking at the overall numbers paints Canada as a lot less safe than the US, but digging in a bit suggests that we're actually over-reporting in relation to the US. After having lived in the most violent city in Canada (Winnipeg) for 20+ years, and in some of the most violent places in the US (Baltimore, DC, Richmond) I can say, anecdotally, while I may've been more worried about getting a punch in the mouth in Winnipeg for telling someone to go fuck themselves, I was a lot more worried about getting shot so kept my mouth shut in Baltimore.
