York Wilson (1907–1984) was a Canadian painter and muralist known for his transition from social realism to geometric abstraction. Trained at Central Technical School, he began his career as a commercial artist before shifting to fine art in the 1940s. Wilson’s time in Mexico deeply influenced his work, introducing him to mural techniques and materials such as pyroxylin. His notable murals include those at Toronto’s O’Keefe Centre (now Meridian Hall), the Imperial Oil Building, and the Salvation Army Headquarters. A member of the Royal Canadian Academy of Arts, he also served as president of the Ontario Society of Artists. His legacy is preserved through the York Wilson Foundation for Visual Arts, which has donated hundreds of his works to public collections.
