John Ellwood Madill (15 January 1915 – 5 December 1999) was a Progressive Conservative party member of the House of Commons of Canada.
[1] Elwood Madill was an insurance agent in Orangeville, Ontario when he won the local Progressive Conservative nomination for the Dufferin—Simcoe riding on 16 February 1963.
Due to riding boundary realignments in 1966, Madill campaigned in the newly formed Peel—Dufferin—Simcoe riding in the 1968 election but lost to Bruce Beer of the Liberal party.
Beer only served one term in Parliament before Madill won back Peel—Dufferin—Simcoe in the 1972 federal election.
Besides his insurance practice, Madill was also a businessman and farmer during his career.
