The party was left without any parliamentary seats following the 1980 federal election, and thereafter declined into irrelevance, though it nominally continued to exist until 1993.
The ideology was embraced by the Reverend William Aberhart ("Bible Bill"), who formed the Alberta Social Credit League in 1934.
Social Credit won the 1935 provincial election in a massive landslide, and Aberhart became Premier of Alberta.
This measure was disallowed by the Supreme Court of Canada on the basis that only the federal government was authorized to issue currency.
In 2017 it was renamed to the Pro-Life Alberta Political Association, which has only tenuous connections to its social credit heritage.
The British Columbian movement was largely at odds with the Albertan wing and sought to distance itself from William Aberhart's religious preaching.
Social Credit's first government in British Columbia was a very small minority, but they were elected to a majority a year later.
The party collapsed in the 1996 election when it failed to win a single seat in the legislature, and received only 0.4% of votes cast.
He and Gilberte Côté-Mercier founded a lay Christian group called the "Pilgrims of Saint Michael", based in Rougemont, Quebec, that promotes social credit monetary policy coupled with conservative Catholicism.
Even and Côté-Mercier also founded the Union des électeurs in 1939 as a provincial party based on social credit theories and recruited Réal Caouette to the movement.
The movement was able to win a post World War II by-election under the Union des électeurs label, with Caouette being sent to the House of Commons of Canada.
Caouette ran for re-election as a union des electeurs candidate and lost his seat in the 1949 federal election.
Caouette continued to run in elections unsuccessfully through the 1950s over the objections of Even and Côté-Mercier and split with them on May 4, 1958 to form Ralliement des créditistes as the Quebec wing of the Social Credit Party of Canada with himself as leader.
Although BC and Alberta would elect a few Social Credit Members of Parliament (MPs) in that decade, it would be Quebec that maintained the party's national presence after 1962.
In the 1962 election, Social Credit won 26 of 75 seats in Quebec, beating the Progressive Conservative Party.
They continued to finish in second place in terms of federal seats from Quebec until their last MPs fell with the minority government of Joe Clark in 1980.
The party formed a provincial wing in 1970, the Ralliement créditiste du Québec, which benefited as the UN declined after the death of Premier Daniel Johnson in 1968.
In Ontario, the party unsuccessfully ran candidates in most provincial elections from 1945 until 1975, never obtaining electoral support beyond a negligible level.
