They say there is white privilege. There surely is also black privilege among the lefty progressives. They bend over backwards to showcase black achievement. Come on! This woman will be a face on our currency for decades? 
I'm sorry they had discrimination in N.S. but this is just ridiculous. There are surely more notable people to put on our money. What about Joseph Brant or Tecumseh? Both were Native leaders who fought alongside the British during the creation of Canada. What about Riel or Gabriel Dumont or something? 
If you want a woman suffragette example there are plenty who devoted their lives to the cause. Im sure there are even more notable Black woman. Why not Herriet Tubman. Didn't she also spend some time in Canada and she was a major figure in the underground railroad and devoted her whole life to the cause.
