Appointed Rector of College Mathieu in Gravelbourg in 1927, he was still at this post when named titular bishop of Zerta and Vicar Apostolic of Grouard, Alberta on December 19, 1929.
Consecrated in Ottawa on May 1, 1930, he served the Grouard vicariate for seven years before his appointment as Bishop of Gravelbourg on June 2, 1937. Due to commitments in the vicariate, the new bishop was installed only on October 25.
His episcopate saw the end of the Great Depression and drought years, and the beginning of a world war.
Ill health forced him to submit his resignation, which was accepted early in December, 1942.
He returned to Montreal to take on the procuratorship of the Oblate missions in Canada.
