Corporal Ainsworth Dyer, PPCLI was a black man born in Canada. Until I saw pictures in the paper, I didn't know he was black. The army, the press, and I didn't care. He was army green, just like everyone else who does their job in the army, and he was one of ours.
I wouldn't expect you to see too many more racists in the CF than anywhere else in Canada. Any stories I have heard about people in the army meeting racist types were mostly of the "you wouldn't believe this guy..." kinda stories. On deployment, there may be a certain amount of cross-cultural friction that is normal for all human beings, but it's nothing you wouldn't be used to seeing anywhere else.
The beauty of Canada as a whole is that we are culturally insensitive in the best possible sense. We don't really believe that anyone is different because of the colour of their skin, preferring instead to judge people on the content of their character.
