About Robert James Manion

Lived 1881 – 1943 (aged 61). Robert James Manion was a Canadian physician and politician.

Robert James Manion (19 November 1881 – 2 July 1943) was a Canadian politician who led the Conservative Party of Canada from 1938 to 1940. Prior to his leadership of the party, he served in Prime Minister Arthur Meighen and R. B. Bennett's cabinets.

A Liberal prior to World War I, Manion was elected to the House of Commons in 1917 as a member of the pro-conscription Unionist Party led by Prime Minister Robert Borden. After the war, he served as a Conservative Member of Parliament until his defeat in 1935. In 1938, Manion was elected leader of the Conservatives, which was shortly relabeled as National Government. Despite his pro-conscription stance in World War I, Manion campaigned against conscription in World War II in the 1940 federal election. Manion also ran on a platform of forming a wartime coalition national unity government. In the election, the National Government lost in a landslide, keeping their seat count exactly the same as in the 1935 federal election. Manion also lost his seat of London, and subsequently resigned as leader. Shortly after, Manion was appointed director of Civilian Air Raid Defence. He died in 1943 in Ottawa.

Early life

Manion was born in Pembroke, Ontario, of Irish Catholic descent, the son of Mary Ann (O'Brien) and Patrick James Manion. He studied medicine at Queen's University, Kingston, Ontario, and at the University of Edinburgh before settling in his hometown of Fort William, Ontario, where his parents had lived since 1888.

In 1915, he enrolled in the Canadian Army Medical Corps. Attached to the 21st Canadian Battalion, he was awarded the Military Cross for heroism at the battle of Vimy Ridge.

Political career

Manion was elected to the House of Commons during the conscription election of 1917 as a Unionist Member of Parliament (MP) for Fort William, Ontario. A member of the Liberal Party before the war, he supported Conservative Prime Minister Robert Borden's pro-conscription Union government that was formed as a result of the Conscription Crisis of 1917. Manion remained with the Conservative Party after the war. The new prime minister, Arthur Meighen, appointed him Minister of Soldiers' Civil Re-establishment in 1921. He spent most of the 1920s on the opposition benches, except for a few months in 1926 when he served as a minister in the second Meighen administration, including the position of Postmaster-General.

Following the federal election of 1930, the new Conservative Prime minister R. B. Bennett appointed Manion Minister of Railways and Canals. However, the economic crisis of the Great Depression destroyed the Bennett government, and Manion, with many others, lost his seat in the 1935 election. According to historian Roy Piovesana, Manion's loss was partly attributable to his failure to cultivate his Fort William riding.

Conservative Party leader Despite not having a seat, Manion won the Conservative leadership convention with backing of an "improbable coalition" of Orange Order delegates from Ontario and delegates from Quebec. Conservative Party members hoped that his Catholicism and marriage to a French-Canadian, Yvonne Desaulniers, would help the party in Quebec where the perception of the Tories as being anti-French and anti-Catholic Orangemen had hurt their prospects. Manion entered the House of Commons through a by-election in 1938 in London.

Following his by-election win, Manion subsequently campaigned against conscription despite the fact that he had joined the Unionists in 1917 because he favoured the draft. Manion moved the Conservatives to the left and was criticized as a socialist due to his call for action against unemployment and his desire to, in his words, "bring a greater measure of social justice to all our citizens."
