To directly answer your question, I -- a brown man -- have never had a bad interaction with police. I assume Canadians are also annoyed when given tickets, but really police have been nothing but helpful, and I feel free to approach police officers and ask questions.
My dad -- also brown -- has also had the police called on him (usually because he's berating someone at a store or something), and the cops have only ever diffused the situation, never added to it.
