You are correct. Thanks for speaking out against this myth that Canada is some holyland. There is a lot of racism in Canada based on what I've seen and what I've studied in Sociology of Inequality at University.
It's no accident that many minorities, especially including the first nations population, fill those short-term, unskilled, vocational jobs. It's no accident there are many professionals with degrees still working as taxi drivers in Canada. It's no accident that the white population, typically male as well, are healthier, attain more promotions, and do not fill those short-term, unskilled labor as plentifully.
