He was first elected to Parliament at the Rimouski riding in the 1917 general election, initially under the "Laurier Liberal" banner used as a result of the Conscription Crisis of 1917 which split the Liberals into pro-conscription Liberal Unionists and anti-conscription "Laurier Liberal" factions. He was re-elected there in 1921 as a Liberal. d'Anjou resigned on 4 October 1924 to open the seat for Eugène Fiset.
