Generally, in cities you won't have really any problems. My fiancee is Turkish and we live in the prairies and she's never had anything happen. Folks stumble on her name sometimes but it's not really racism.

If you go rural, you always up your chances of encountering more racism. Rural PEI/NB will be accidentally racist, rural AB/SK will not care if they're racist. Generally this is true unless you're camping/hiking, when you wrap back around to people who are generally just happy to see fellow outdoorsmen.

Much of North American racism isn't from individual people but in systems. My fiancee's experience is that European systems are more likely to be equitable but the people will be racist. In general, if you visit Canadian cities from Vancouver to Montreal, I wouldn't expect you to have any racist encounters.
