In addition to his work with the Group of Seven, his long career included serving as a war artist during World War I (1917–19) and teaching at the Banff School of Fine Arts.
Jackson made a significant contribution to the development of art in Canada, and was successful in bringing together the artists of Montreal and Toronto.
His art nouveau style highlighted the Canadian countryside, showing visions of a land many had thought barren and boring.
His easy style, featuring rolling rhythms and rich, full color, exerted a strong influence on Canadian landscape painting.
A.Y. Jackson‘s artwork can be found in galleries all across the Internet.
