In 1921, Clubb served with John Bracken on a special committee to review the prices of oil and gas for Manitoba's agricultural community.
[1] The United Farmers and their allies won an unexpected majority government in the 1922 election, and took office as the Progressive Party of Manitoba.
At the end of the meeting, the only others candidates still under consideration were federal Members of Parliament Thomas Crerar and Bob Hoey.
Re-elected by a landslide in the 1927 election,[1] Clubb helped oversee a controversial leasing arrangement with the Winnipeg Electric Company (WEC) in the late 1920s.
This arrangement provoked a scandal in 1929, when Clubb acknowledged before a royal commission that he had purchased WEC shares the previous year, when negotiations were still in progress.
In fact, his share purchase was arranged by John Thomas Haig, a prominent Conservative legislator and personal friend.
This policy of cooperation led to a formal alliance in 1932, and Clubb was re-elected in that year's provincial election as a supporter of the "Liberal-Progressive" government.
[1] Clubb faced a difficult re-election in the 1936 campaign, and resigned from cabinet in 1940[1] with the creation of an all-party coalition government.
