Well, not all of those millionaires are "insanely rich", as in "having a million dollars fluid", but are upper middle class and have some ground or something similarly worthwile. I know quite a few millionaires, but many of these are just farmers or owners of a flat in or near a major city. They surely don't live a bad live, but they don't have thousands to pour in dogecoin or casinos.
My point is, take these numbers with a grain of salt.
I'm actually surprised at how low those numbers are. Only 1322 millionaires in Canada? Really? I know most people get a mortgage, but there are a ton of houses in Toronto and Vancouver that are over $1m.
