At the federal level it was led by
Maxime Raymond, who had been Member of Parliament (MP) from the province of
Quebec since the
1925 federal election. He and two of his
Liberal colleagues (
Édouard Lacroix and
Pierre Gauthier)
crossed the floor to sit as Bloc populaire canadien MPs. The Bloc populaire won a federal by-election in 1943. The Bloc populaire's entry into provincial politics antagonized Quebec Premier
Maurice Duplessis, leader of the
Union Nationale, who henceforth transferred his party's federal support to the "Independent Group" of anti-conscription MPs led by
Frédéric Dorion in the
1945 federal election. In the
1945 federal election, the Bloc nominated 35 candidates. All of them except two ran in
Quebec-based ridings. (Lionel Campeau, ran in the district of
Nipissing in
Northern Ontario and Léandre Maisonneuve ran in the
Eastern Ontario riding of
Prescott. Only two candidates were elected as Members of Parliament:
Maxime Raymond and
René Hamel. Though former Montreal mayor
Camillien Houde was officially listed as an independent candidate, he was reported to be the Bloc populaire's co-leader in the 1945 election. In addition to the Bloc populaire, there was also an "Independent Group" of five anti-conscription MPs led by
Frédéric Dorion which included
Liguori Lacombe,
Wilfrid Lacroix,
Sasseville Roy and
Emmanuel D'Anjou (D'Anjou had joined the Bloc in June 1944 but had left to join Dorion's group by the time of the 1945 election). Additionally,
Arthur Cardin quit Mackenzie King's cabinet in May 1942 over the conscription issue to sit as an anti-conscription independent MP. ==Decline==
