Did she contribute a lot?
It sounds like a copycat Rosa Parks story. Which is just another example of Canada trying to piggyback the American narrative of race relations on to Canada. The truth is Canada was far less diverse than the States prior to Trudeau Sr. I know about the famous African-Canadian community in N.S. and some in Ontario etc. but there was nothing comparable to the millions of former slaves in the USA. Canada was less than 1% non-white in 1961. So now we get immigrant populations in Canada who have learned to imitate the African-American grievance identity and will act out based on that when they are in fact immigrants or the children of immigrants.
 Very irritating.
