Born in Louiseville (Mauricie), Quebec, Canada, she was an early member of Paul-Émile Borduas's Automatistes art movement.
She signed the manifesto Refus global, a watershed event in the Quebec cultural scene, in 1948. In 1953, she moved to Paris, where she worked for 13 years in drawing and painting and was introduced to the art of stained glass, for which she would become best known. One of her stained-glass windows is at Champ-de-Mars metro station in Montreal.
It was one of the first non-figurative works to be installed in the metro, in defiance of the didactic style present in other works of the period, and signalled a major shift in public art in Montreal between the policies of then art director Robert Lapalme and future art director and fellow automatiste Jean-Paul Mousseau.
