William James Major (November 10, 1881—August 13, 1953) was a politician in Manitoba, Canada. He served in the Legislative Assembly of Manitoba from 1927 to 1941, and was a prominent cabinet minister in the government of John Bracken.
Major was born in Yeovil, Somerset, England, worked in the law office of Athelstan Rendall and migrated to Canada in 1901. He was educated in Manitoba, was called to the Manitoba Bar in 1913, and worked as a barrister-at-law. He also became active as a freemason.
Major was chosen as a star candidate of the governing Progressive Party in the 1927 provincial election. In this period of Canadian history, newly appointed cabinet ministers were required to resign their seats and seek the renewed support of their electorate. This was inconvenient for most government leaders, who frequently circumvented the regulation by appointing or shuffling cabinet ministers just before general elections. Major, despite his lack of political experience, was named as Bracken's Attorney General on April 29, 1927, and fought the election in this capacity. He proved an effective campaigner and was elected for Winnipeg, which returned ten members through the single transferable ballot voting method.
As Attorney General, Major oversaw construction of the Headingly jail and designed a liquor control act that lasted into the 1950s. He began an extensive revision project of the province's magisterial system in 1930, and was finally able to present his finished report to the legislature in 1940.
In 1929, Major and fellow cabinet minister William Clubb became caught up in a conflict-of-interest controversy involving the Winnipeg Electric Company (WEC). Both ministers had purchased shares in the company while negotiations for a government lease were still pending. It may be noted that opposition legislators had also purchased WEC stock during this period, and that Clubb's shares were in fact purchased by prominent Conservative legislator John Thomas Haig. Bracken initially defended both ministers, but was forced to call for their resignations on February 22, 1929.
