"Between 1982 and February 2020, 64 out of the 116 mass shootings in the United States were carried out by white shooters...Broadly speaking, the racial distribution of mass shootings mirrors the racial distribution of the US population as a whole."
Mass shootings are indeed, almost without exception, carried out by men.

As to socio-economic factors, one study reports "Counties with growing levels of income inequality are more likely to experience mass shootings. We assert that one possibility for this finding is that income inequality fosters an environment of anger and resentment that ultimately leads to violence."

While it may be true in general, IMO income inequality doesn't apply in this case.
There are far fewer mass shootings in Canada, the list is very short:

I'm not willing to compile statistics, but IMO, almost none of the other shooters fit the profile of a PWG: It includes people from immigrant backgrounds many young men under age 20, several who complained they'd been bullied, etc
I think possibly there is a tendency to read about and remember the few mass shootings by PWGs, because there's more media coverage, and possibly because their actions have more impact on other PWGs and PWW. IMO, that's not a problem with the legal or other system, IMO that's a problem of believing that crime is something that never should never occur in privileged white society.
Note: The crime of family annihilator is a separate category, and doesn't fint in this case.
The page you linked, for mass shootings in Canada, shows that the racial breakdown is similar to the population census. Unlike the US, though, there are no female shooters listed. 60% of the Can shooters are white male, but as you point out, almost none are PWG. Vietnamese immigrant, Phu Lam, who shot mainly members of his family, and ?Dene? Randan Fontaine, who shot his cousins and people at school, don't fit either, given the family connections.
My point was, however, about the treatment of the PWG by LE. Nowhere did I assert that most of the shooters are PWG. I focused specifically on PWGs - which, as you've shown, needed to be expanded, since they're in the minority statistically. If you want to include white males of lower statuses, such as the poor, working, and professional classes, yes, they too are given privilege when compared to BIPOC (Black Indigenous, People of Color). You can compare how LE dealt with
white mass shooter academic James Holmes, who actually killed other people, to
black George Floyd, who alleged attempted to pass off a counterfeit $20 at a corner store.
Let's look inside Canada, where two Metis-Cree,
Jake Sansom and Maurice Cardinal, were allegedly ambushed and shot by two white working/skilled trades class men. In this region, like most across Canada, where Metis/First Nations interact with white settlers, POC experience frequent racist harassment, and, in the case of
Thunder Bay, murder, especially if you're a FN student from the north. Reports of death threats and racial harassment from random working/skilled trades white men against BIPOC were made to the RCMP in the Glendon region, where Sansom and Cardinal resided. The RCMP ignored the systemic racist intimidation and only acted when they were faced with 2 deaths determined by the coroner as homicide. Couldn't write it off as another drunken native teen, all alone, drowning in TBay's McIntyre River.
The white male privilege goes far beyond PWG and mass shootings. It's systemic in both Canada and the US. Maybe because of the one percenters' status and the not-so-wealthy but still rich, like GW, people like me tend to single them out.
