Sénart founded and conducted several Montreal choral groups, including the Choeur Kattialine (1962-74), the Ensemble vocal de Montréal (1976) and the Choeur de Montréal (1981-90). The last-named, numbering over 100 choristers, gave many concerts in the region, collaborating with, among others, the Musiciens de l'Archipel, a chamber orchestra also founded by Sénart in 1981, the MSO, the Orchestre métropolitain (for a performance of Jean le Précurseur, 1988) and the OJQ (Caïn, 1988). Sénart coached the MSO choirs during its 50th season (1983-4), including the performance of Mahler's monumental Symphony of a Thousand at the Forum. In 1984 he became the director of the newly-founded Ensemble Vocal de Sherbrooke. As orchestra conductor, he has led the OJQ (assistant conductor, 1979-80), the MSO (Matinées symphoniques), the CBC Quebec Chamber Orchestra and the Sherbrooke Symphony Orchestra (artistic director, 1985-6). He published Le Geste Musicien (Montreal 1988), an abstract on conducting which received a National Choral Award from the Association of Canadian Choral Conductors in 1990.
Sénart was a teacher and conductor of the orchestra and choir 1969-77 at the St-Laurent Cegep, director of the orchestral class and director of choral activities 1973-90 at the École Vincent d'Indy, and choral conducting teacher 1973-86 and orchestra conductor 1987-8 at the University of Montreal. In 1990 he settled in Aix-en-Provence.
