Ellwood Madill

John Ellwood Madill (15 January 1915 – 5 December 1999) was a Progressive Conservative party member of the House of Commons of Canada. He was born in Melancthon, Ontario.

From 1952 to 1957, he was a municipal councillor for Mono Township, subsequently its deputy reeve to 1959, then reeve from that point until 1963. In 1962, he was warden of Dufferin County. Madill won that seat in the federal election later that year. He was re-elected to a second term in 1965.

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. However, after his term in the 29th Parliament, Madill left federal political office after his defeat to Ross Milne in the 1974 federal election.

Besides his insurance practice, Madill was also a businessman and farmer during his career.
