A native of the city of Québec, he studied first at the College of the Brothers of the Sacred Heart of Montmagny, then at “l’École des Hautes Études Commerciales” in Montréal where he obtained a degree in Commerce in 1934. He went to Paris to study at the Faculty of Law of Paris. In that same city, he graduated also from “l'École Libre des Sciences politiques” where, in 1937, he supported a thesis under the direction of André Siegfried. He spent all his academic career teaching at “l’École des Hautes Études Commerciales” in Montréal, this from 1938 to 1974, year when he retired. He also taught at “L’École des Relations industrielles” of the Sherbrooke University. He acted as director of the magazine “L'Actualité économique” and was, since 1949, director of the “Service de la Documentation économique” which became, in 1959, “l’Institut d’Économie appliquée”. Very solicited as an economist, he served as advisor for the Inquiry Board on Constitutional Problems Commission d'enquête on the constitutional problems (Commission Tremblay) this from 1953 to 1956, and from 1955 to 1959, as technical director of the Economic Orientation Council of the Chamber of Commerce of the Province of Quebec. From 1970 to 1980, he served as President of the Ludger Duvernay Foundation. He chaired also the Canadian Society of Economic science, from 1968 to 1971, and the International Centre of Research on Public enterprises and cooperatives, from 1975 to 1981.

A strong believer of the importance of the cooperative way for the economic development of Québec, he served as a member of the board of the Consumers Cooperative of Montréal. His action was also imbearing in the nationalist mediums in which he insufflated his passion for Québec and the French language. Thus, he chaired the “Ligue d’Action nationale” from 1955 to 1985 and was director of the magazine “L’Action nationale”, from 1959 to 1968. He held the helm of the Saint-Jean-Baptiste Society of Montréal, from 1969 to 1973, and also the “Mouvement Québec Français”, from 1972 to 1980. He left to posterity a very imposing scientific production. He spent the last years of his life to the development and the promotion of the great economist Esdras Minville’s works, a man he considered his true mentor. He died in the LaSalle borough of Montréal and had asked to be buried in his beloved region of Charlevoix, beside his parents.
