It absolutely can and has been. [1]
> Photos of the teenager’s corpse show a deep cut on his right arm, horrific bruising on his neck and chest. His face is swollen and covered with cuts. A silhouette of violence runs from the corner of his left eye over the cheekbone to his jaw, and his legs are pocked with small burns the size of a lighted cigarette. But police in Japan’s Aichi prefecture saw something else when they looked at the body of Takashi Saito, a 17-year-old sumo wrestler who arrived at a hospital in June. The cause of death was “heart disease,” police declared.

The murder rate in most areas of the US is under 5 in 100,000.
There's less than 50 police departments in the US where you can expect even 50 murders per year. With numbers that small, you'll run into a lot of noise.

Your data is for the Greater Toronto Area. The commenter above you was referring to the City if Toronto (which is one of several municipalities in the Greater Toronto Area).
Murder rates don’t include “justifiable homicide”, because police departments are not required to report officer-involved shootings or killings to the federal government, nor the outcomes of any investigations into them. Which can also be gamed.
I’m not saying that radically transforms the statistic—I have no idea. But it’s a factor.
Having a deaths count -- which itself definitely has error bars, otherwise what the heck are missing persons estimates -- doesn't mean you have a correct attribution of those deaths. Never trust data in the absence of auditing how it got there.
