David Kilgour

David Kilgour was an Alberta politician who served as an MP from 1979 to 2006. He is one of the few Canadians to have crossed the floor twice: first from the Progressive Conservatives to the Liberals in 1990 over Meech Lake, and later from the Liberals to sit as an independent in 2005 over the sponsorship scandal. He went on to become a prominent international human rights advocate, particularly regarding organ harvesting in China.
