Abell taught at Acadia University in Wolfville, Nova Scotia, Canada from 1928 to 1943. He was one of the first professors of fine art at a Canadian university. Abell helped to found the Maritime Art Association, and was founding editor of Maritime Art. The first issue of Maritime Art, the first magazine in Canada devoted to the visual arts, appeared in October 1940. The Carnegie Corporation provided a small grant to help with starting up, and the Maritime Art Association gave organizational support. Abell was editor, but Violet Gillet was responsible for production of the first issues. In the late 1930s Abell saw Canadian modernists, particularly women such as Pegi Nicol and perhaps Paraskeva Clark, as a "very important group of young Canadian painters... more important than the Group of Seven." André Charles Biéler organized the first conference of Canadian artists in Kingston, Ontario. Abell told the delegates at the Kingston conference that Canada was a "cultural plutocracy... determined by a small group possessing great wealth." He proposed that experiments in children's art, folk art and amateur creative workshops were "movements of modern art that have broken old forms and prepared the way for new ones, with increasing emphasis upon the creative possibilities in the common man. The Kingston conference led to the foundation of the Federation of Canadian Artists in 1941. The Federation was divided into regions, each with a regional organizer. Abell was head of the Maritimes region. Walter Abell's journal Maritime Art became Canadian Art in 1943 when Abell moved to Ottawa to join the staff of the Art Centre of the National Gallery of Canada. Abell moved on to Michigan State University where he taught from 1943 to 1956. He died in 1956 in East Lansing, Michigan.
