Alphée operated a sewing workshop from 1950 to 1966, at first on the second floor of the garage. In 1954 he acquired the old school no. 1 of rue Dupont of the "Commission scolaire de Sainte-Thècle" (School Board) to make a sewing workshop (in the basement), a linoleum shop on the 1st floor, the funeral home on the 2nd floor. After an experience as municipal councilor since 1945, Alphée is named the 20th mayor of the parish municipality of Sainte-Thècle. He completed three mandates until 1957, when the "village d'en bas" (village from below) merged with the municipality of the village.
