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. She was particularly inspired by the work of French glass artist, Michel Blum and his innovations. Ferron returned in 1966 to Quebec, where she worked exclusively with stained glass for the next two decades. One of her stained-glass windows is at
Champ-de-Mars metro station in
Montreal, Quebec. 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. Other examples of her works can be seen at
Vendôme metro station,
Centre hospitalier universitaire Sainte-Justine, and the
ICAO headquarters, in Montreal; the
Place du Portage in
Gatineau, Quebec; and the
Granby, Quebec courthouse. ==Awards and honours==
