Arthur Lismer's style was influenced by his pre-Canadian experience (primarily in Antwerp), where he found the Barbizon and post-impressionist movements a key inspiration.

Collaborating with the group of artists who would, in 1919, become the Group of Seven, Lismer exhibited the characteristic organic style, and spiritual connection with the landscape that would embody that group's work. During the Centennial of the City of Toronto, in 1934, Lismer was on the Pictures Committee. His work in art education was effective; and this service to the wider community caused Lismer to become influential in ways not achieved by his artist colleagues. For example, he started a children's art program at the Art Gallery of Toronto which became successful in the 1930s.

In 1967, he was made a Companion of the Order of Canada. Lismer died on March 23, 1969 in Montreal, Quebec.
