United Progressive

Unity or Progressive Unity and United Reform was the name used Canada, by a popular front party initiated by the Communist Party of Canada for the 1940 Canadian election. Dorise Nielson was elected in North Battleford under the Unity label while Walter George Brown was elected as a United Reform MP in Saskatoon City.

Nielson was a supporter of the Communist Party and ran for re-election in 1945 federal election as a Labor-Progressive Party candidate (the name adopted by the Communist Party after it was banned) and was defeated.

In the 1940 federal election, William Halina sought election to the Canadian House of Commons in the riding of Vegreville, Alberta under the United Progressive banner. Halina won 2,727 votes, or 19.4% of the total cast, placing third behind the Social Credit and Liberal candidates, but ahead of the Co-operative Commonwealth Federation candidate.

His campaign may have been related to the Progressive Unity platform that elected communist Dorise Nielsen in Saskatchewan in the same election. Halina ran for the communist Labor-Progressive Party in the 1945 election.
