After he abandoned his original career intent of becoming a priest, he studied dance with Maurice Morenoff in Montreal and later with prominent teachers in New York City, London, and Paris.
After twenty-one years with the company, he returned to Montreal in 1965 and accepted the invitation of Ludmilla Chiriaeff to become co-artistic director and resident choreographer of Les Grands Ballets Canadiens.
[1] Nault's best-known work is probably his spectacular production of Casse-Noisette (The Nutcracker), which has been performed annually during the Christmas season in Montreal for many years.
Nault was also choreographer and ballet master for the École Supérieure de Danse du Québec, the school established by Madame Chiriaeff in 1966.
He remained active with Les Grands Ballets Canadiens for many years and in 1990 was named choreographer emeritus, a title he held until his death.
