AFAIK, the "defund the police" chant was supposed to be in response to American police forces buying army vehicles and gear. That is not a thing in Canada. I also get the general impression that whoever came up with "defund the police" has anarchist inclinations. It's basically doublespeak. They keep saying that "defund the police" only means "reform the police", but what they actually want is to dismantle the police, which is exactly what "defund the police" sounds like.
