She held her first solo exhibition in 1949 at Librairie Tranquille on Sainte-Catherine Street in Montreal, one of the few venues at the time dedicated to avant-garde painting. In 1953, she moved to Paris with her three daughters. During her thirteen-year stay, she took part in numerous exhibitions, expanding the reach of her work. It was also in France, under the guidance of Michel Blum, that she discovered the art of glasswork. In 1957, despite living abroad, she received a major grant from the Canada Council for the Arts. In 1961, she won the silver medal at the São Paulo Biennale. Her left-wing political views, however, caused some difficulties; notably, her association with an anti-Franco activist led to her expulsion from France in 1966. Upon returning to Quebec, she taught at Laval University and created the stained-glass installation at the Champ-de-Mars metro station in Montreal, regarded as one of her masterpieces. In 1972, she was inducted into the Royal Canadian Academy of Arts, and in 1983, she received the Paul-Émile-Borduas Prize, the highest honor in visual arts awarded by the Quebec government.
