Born in Montreal, Jean Gareau has been educated as an architect at the then École des Beaux-Arts de Montréal where the cursus included art studios. He had been practicing painting earlier and had studied with sculptor Louis Archambault and painter Jacques de Tonnancour. After a career as architect, he has resumed painting which he had temporally abandoned. More recently, he has worked with David Gillanders at the Montreal Museum of Fine Arts and in the studio of Pierre Lafleur, painter and muralist. Now an autonomous artist, he works in his own studio. His favourite mediums include acrylic paint and pastel.
Jean Gareau’s works have been shown in solo exhibitions in Paris, Montreal, Outremont and Ile d’Orléans. He has also taken part in 20-odd exhibitions throughout Québec.
A number of works are part of private collections, mostly in Quebec and in France.
