I have a couple of other candidates lined up for erasure: an former "Indian Agent" (and therefore a supporter of residential schools) and MP from Port Albernie BC, elected to parliament 6 times, who was an avowed racist who tried very hard to have Asians barred from Canada. Who publicly declared the Japanese request for voting rights "claptrap."  His name is on a street in Port Alberni and--wait for it--an elementary school in the city. City Hall moved to change the name--and there was a firestorm of protest from residents.   A. W. Neill's name remains on street and school. 

There is a "Famous Five" statue of Nellie McLung in a downtown Calgary park, opposite the city hall, celebrating this pioneer champion of women's rights.  She also championed prohibition, too. Worse, she took payments for speaking on behalf of the "Drys."  Not so incidentally, she was also a public advocated of Eugenics, which advanced the notion that the mentally ill should be sterilized. Tens of thousands were.
