Lincoln Alexander, although he's no longer a politician or lecturer (retired). When I was in HS (1984-88) you were only required to take grades 9 & 10 history, and that covered mosty North American history (Champlian, Cortez, Natives and then the world wars), where as the Canadian histoy wasn't taught in depth until grades 11 & 12. Political classes were optional. We learned about Lincoln Alexander, and other prominent African-Canadian political figures in Canadian history/politics. I have no idea what the history requirements are anymore, but if they are anything like when I went, obviously if the kids are not taking the classes that teach them about Canadian history and politics they are not going to know many (if any) politicians, of any race or gender through our history.
