Born in Valleyfield, Quebec, Ainsley studied painting and printmaking at the University of Quebec, Montreal (1975-79) under Suzanne Duquette. She taught at the Musee d'art contemporain de Montreal (1996 -97), and has been active in the commercial art and design field since 1981. Ainsley works with mixed media, acrylic, pastel and serigraphy. Her subject matter is varied, very colourful and usually abstract. She often uses forms, cut from masonite and paper, that stand as individual works or part of a larger composition. She has exhibited at the MAC and EBAM, and is represented in the MQ and MAC.
