W. E. N. Sinclair
William Edmund Newton Sinclair (June 28, 1873 – November 26, 1947), known as W.E.N. Sinclair, was a Canadian barrister, solicitor and politician.
He was born in Whitby Township, Ontario, the son of John Sinclair, and was educated at Toronto University, receiving a bachelor's degree in law. In 1907, he married Ella Minerva Montgomery; he married Edna Worden in 1918 after his first wife's death.
Sinclair ran for the leadership of the party in the 1922 leadership convention, but lost to Wellington Hay. Hay resigned following a disastrous election result, and Sinclair served as interim leader of the Ontario Liberal Party from 1923 to 1930 and also as Leader of the Opposition in the provincial legislature. He was interim leader for that length of time (and through the elections of 1926 and 1929) because of the party's state of disorganization and inability to hold a proper leadership convention.
The Liberals remained at the 14 seats they had in 1926, and dropped to 13 seats in the 1929 election. Sinclair initially decided to run for the permanent leadership in 1930, but because of the party's failure to make gains during his tenure, he attracted little support, and withdrew before balloting began. He remained Leader of the Opposition until the 1934 election because the newly elected leader, Mitchell Hepburn, did not have a seat in the provincial legislature. Sinclair was re-elected in the 1934 election that brought the Liberals to power but Hepburn, the new Premier of Ontario, did not appoint him to Cabinet. Sinclair sat as a government backbencher for three years and then retired from the legislature at the 1937 provincial election.
Sinclair also served as mayor of Oshawa from 1910 to 1911, in 1915 and from 1932 to 1934.
