Because 80% of most desirable US city Denver (like as what I'm gathering is also true of Canadian cities) is ghetto. This is what capitalism and dirtmocracy has brought. Congratulations motherfuckers!
USA is number one when it comes to ghettos pal. Canada can't compete on that front.
What Canadians consider ghetto (in a Canadian city) is much different from America.
For example, Windsor is considered by some to be a ghetto because its mostly working class. We don't have actual "ghettos" like in the USA.
We also don't have a huge number of African Americans and there are no "black" neighborhoods in Canadian cities like in the US.
Windsor is a great example. According to a not too dated census:
In 2016, Windsor's population was 217,188. 10,675 are blacks. ~5%
Across the river in Detroit African Americans make up 82.7% of the total population.
Canadas black population is approx 3.5%. This includes mostly blacks of Jamaican & Haitian heritage.
According to the 2011 Census, 945,665 Black Canadians were counted, making up 2.9% of Canada's population.
In the 2016 Census, the black population totaled 1,198,540, encompassing 3.5% of the country's population.
