Tommy Douglas certainly had an impact - mind you, I was split between Douglas, Terry Fox and Trudeau ...
Here's Tommy's bio - Canada's "Father of Medicare" as well as the first premier of a socialist party in North America.
(On a side note - Tommy's grandson is none other than Kiefer Sutherland (Shirley Douglas, Tommy's daughter, married Donald Sutherland)
