In 1945, Dallaire returned to Canada. He taught painting at the École des beaux-arts in Québec City from1946-52, and worked for the National Film Board in Ottawa from 1952-57, where he illustrated short educational films. Many works from this period were also commissioned murals. The works show varied stylistic influences and are recognized for their draftmanship and spontaneity in subject and use of colour. Dallaire was inspired by Italian theatre, mythological figures, surrealism, synthetic cubism and art brut.In 1959, Dallaire returned to France where he spent the last years of his life in Vence. The works from this period show a very personal approach to modernism. They are characterized by their festive air, and highly schematized forms and rich colours. Dallaire discovered the liberating qualities of abstraction.
In 1968 the first retrospective exhibition of his work was held at the Musée d’art contemporain, Montreal and the Musée du Québec, Quebec."(klinkhoffart.com)
