The unity movement included Communists, members of the Co-operative Commonwealth Federation (despite objections from the CCF leadership), supporters of the Canadian social credit movement, and other populists and reformers opposed to the Liberal and Conservative parties.
It was part of an effort in Saskatchewan and Alberta by the Communist Party of Canada to create a united front bringing together the Co-operative Commonwealth Federation, Communists, other leftists and even the populist Social Credit movement against the Liberals and Conservatives.
Clergyman Walter George Brown won election to the House of Commons as a United Reform Movement candidate in a 1939 by-election in the riding of Saskatoon City, and was re-elected in the 1940 general election with the endorsement of the National Government party (as the Tories were called in 1940).
The URM recruited Agnes Macphail, a longtime Member of Parliament (MP) who had been defeated in the 1940 election to run in the by-election to fill Brown's vacancy.
There was also a "United Reform" candidate in the Saskatchewan riding of Weyburn who ran in the 1940 general election against Tommy Douglas of the CCF.
