William Proudfoot

William Proudfoot, KC (February 21, 1859 – December 3, 1922) was an Ontario politician and barrister.

He was born in Colborne Township, Huron County, Canada West, the son of Robert Proudfoot, an immigrant from Scotland.

Proudfoot was challenged as Liberal leader at the party's first leadership convention in June 1919 and was replaced by Hartley Dewart.

The 1919 election saw the Liberals and their allies drop from 30 seats to 27 with Proudfoot himself defeated in his riding of Huron Centre by the Labour candidate.

No doubt due to Newton Rowell's influence, he was then appointed to the Senate of Canada where he sat until his death in 1922.
