William Henry Sims

William Henry Sims (January 6, 1872 – 1955 Sims was married twice: first to Catherine Emily Marsh and then, in 1909, to Christina S. M. Mounsey.

He was first elected to the Manitoba legislature in the 1914 provincial election, defeating Conservative candidate W.J. Stewart by thirty-three votes in the constituency of Swan River. The Conservatives won this election, and Sims served with his party in opposition.

The Conservative administration was forced to resign in 1915 as the result of a corruption scandal, and the Liberals were called to form government. A new election was called, which the Liberals won in a landslide. Sims was re-elected by an increased majority, and served as a backbench supporter of premier Tobias Norris's government for the next five years.

He was defeated in the 1920 provincial election, losing to Farmer candidate Robert Emmond by 619 votes. He sought to return to the legislature in the 1927 election, but finished third against Progressive candidate Andrew McCleary.
