"More dangerous" here than in the U.S.? Not nearly, not if you count up the fatalities. Also "out in the open" in some states are firearms, that sure helps. Racism is often said to be more subtle in Canada, and I don't doubt it, but that is obviously the lesser of evils given the alternative to the south. Always to be a dreadful part of the human story, like tribalism, even as the best people work against it. 
(By the way, there's at least one very moving music video on youtube, Sam Cooke's original and still best 1964 version of his "A Change Is Gonna Come" with various newsreel scenes from the civil rights struggles of the time -- and the dignity is without exception with the black people not the white, how telling is that.)
