The Union des électeurs (UE) (in English: "Union of Electors") was founded in 1939 by Louis Even and Gilberte Côté-Mercier. It was the first créditiste political movement to be active in Quebec. It ran two candidates, Even and Armand Turpin in the 1940 federal election as part of the Canada-wide New Democracy movement. Even won 17% of the vote and placed third in the riding of Lake St-John—Roberval. Turpin placed second with over 31.8% of the vote in Hull. Even and the Union attended the founding convention of the Social Credit Association of Canada in 1944 and opposed the bid of the western Canadian based Social Credit federal caucus to establish a central party under the leadership of Solon Low. While Even's group ran candidates in the 1945 federal election under the national Social Credit banner and again in subsequent by-elections, by 1949 the Quebec créditistes were again running candidates under the Union des électeurs banner as they were also doing in the Quebec provincial elections.
The Union was accused of anti-Semitism and of distributing the Protocols of the Elders of Zion in Quebec. The Canadian Jewish Congress referred to it as "fast becoming the rallying point of the numerous Jew-haters in French Canada".
The Union des électeurs electoral philosophy was that it was not a partisan political party but an organization which marshals voters to enforce their wishes on their elected representatives. Even's belief, like that of social credit originator C.H. Douglas, was that parties were corrupt and that the party system should be replaced by a "union of electors" who would compel elected officials to follow the popular will. Even and the Union broke with the national Social Credit organization in 1947 due to Ernest Manning's increasingly hostile attitude towards them and his purge of anti-Semites from the movement. The Union influenced some Social Crediters outside of Quebec, including the Social Credit Association of Ontario which stood its candidates in the 1948 Ontario elections under the name "Union of Electors". In British Columbia, there was a "Union of Electors" party which ran as a rival to the British Columbia Social Credit League in the 1949 provincial election.
With Réal Caouette and then P. Ernest Grégoire as leader, the Quebec provincial party contested seats in the 1944 provincial election but won no seats and the 1948 provincial election when it managed to get 9.25% of the popular vote, but again won no seats. It also ran candidates federally: Caouette was elected to the House of Commons of Canada in a 1946 by-election under the Social Credit banner. He failed to win re-election in the 1949 federal election as a Union des électeurs candidate, when the party ran a total of 56 candidates. None were successful.
