This is hyperbole, I live in one of the rougher neighborhoods. The city gov especially the mayor and his cronies have done nothing to actually fix problems, they just do expensive sweeps and cleanup without addressing root causes.
This is a joke, right? Like, either you live in a small town not large enough to have distinct neighbourhoods, or you are so isolated as to not see the abject poverty that many live here. Take Toronto, for example. Right on Mt. Pleasant Rd. and St. Clair you have Rosedale, one of the wealthiest neighbourhoods in all of Canada. If you walk down a street there, you won't find a person making less than $100K. You'll have perfectly maintained roads, bike lanes, and very good private schools (like Upper Canada College), where every kid there pays $50K a year. Go down Mt. Pleasant until it becomes Jarvis St., and continue going down until you hit Dundas St., where the average person makes minimum wage and can barely afford their apartment. And that's just a 2km difference!
Ask anyone whether they would rather live in Forest Hill (again, Toronto) or on Jane and Finch, and you'll get the same answer any time. For Montreal, ask anyone whether they would live in Westmount, or in Sainte-Marie, and again, you'll get the same answer. There absolutely are "good" and "bad" neighbourhoods in Canada, and in some cases, they're just as bad as in the United States (speaking from experience here).
As for being insulated in your upper middle class community. I mean... every country has that. my neighborhood which is a mile and a half from downtown Portland had private security during the entirety of the riots of 2020. These are far left people (which I know based on conversations with my neighbors, yard signs, and who they vocally proclaim they're voting for) and they all collectively decided to hire private companies to ensure the rif-raf doesn't get in. It's exactly like that now. In my own neighborhood, there's nothing, but if you cross the street to the 'wrong side of the tracks' so to speak, it's like an apocalypse (getting better thankfully, due to the recent increase in policing)
And what root causes should they be addressing that they have the means to address?
