For some reason it baffles me that there's a riding in Canada with a whopping 86% minority electorate. Or that there are 8 districts where they are a majority!
This is just in Alberta, too.
But Canada I believe has a slightly higher percentage of non-white people than the U.S. does (this is including First Nations, etc., who strictly speaking are not included in "Visible Minorities") and way more of course than anywhere in Europe. As a result, it's not surprising that there are many ridings that are majority VM/non-white. The UK has a much lower non-white population (around 13% in the UK vs. 27% in Canada) but also has a number of overwhelmingly non-white constituencies.
