Leach studied at the Ontario College of Art, 1969 She has participated in group and solo exhibitions, at the Art Gallery of Ontario, The Power Plant, Contemporary Art Gallery, Vancouver, and the Edmonton Art Gallery. Gordon Hatt, director at the time of the Cambridge Galleries, organized a major exhibition of her work, which traveled nationally to public galleries including the Doris McCarthy Gallery, University of Toronto, Scarborough. Leach also had two major paintings selected by the curators for the 2005, important international exhibition, Extreme Abstraction, at the Albright-Knox Art Gallery, Buffalo.
