He was elected to the House of Commons of Canada as a Laurier Liberal in the 1917 wartime election held during the Conscription crisis of 1917 and defeated Secretary of State Pierre Édouard Blondin. He represented Laurier—Outremont in parliament for four years and did not stand for re-election in 1921.
In 1925, he was appointed to the Legislative Council of Quebec which was the upper house of the provincial legislature as a member of the Liberal Party of Quebec. He sat in the body until 1942 when he was appointed to the Senate of Canada as a federal Liberal. He remained in the body until his death in 1955 at the age of 76.
In his business life he served as president of La Prévoyance insurance company from 1930 to 1936 and was also involved with publishing as president of the newspaper La Presse from 1932 to 1955 and president of the newspaper La Patrie from 1933 to 1955. He was also president of the Canadian Printing and Lithographing Co Ltd and of Provident Adjustment and Investing and was also a director of the Canadian Forestry Association.
