He was born in Shawinigan, Quebec, to Wilbroy Samson, a journalist and farmer, and Irène Carle.
[1] In 1963 and 1964, he was the president of the Jeunesse créditiste du Canada, the youth wing of the Ralliement créditiste, a political party that nominated candidates in federal elections and promoted social credit theories of monetary reform.
In the 1970 Quebec election campaign, in an unfortunate moment of rhetorical transport, delivered this line in reference to the government against which he was running: "Ladies and gentlemen, the Union Nationale has brought you to the edge of the abyss.
The créditistes nonetheless benefited from the decline of the conservative Union Nationale party and made a modest breakthrough, winning 12 seats in the National Assembly and 11.2% of the vote; Samson was elected in the riding of Rouyn-Noranda.
However, the speaker of the National Assembly recognized Armand Bois as parliamentary leader of the Ralliement créditiste du Québec.
He ran again for the leadership of the party at its convention on February 4, 1973, but was defeated by former federal Liberal cabinet minister Yvon Dupuis.
Because Dupuis was not a sitting member of the National Assembly, Samson served as parliamentary leader of the renamed Parti créditiste from March 15 to September 25, 1973.
