 Seath soon realized that by forming a unified alliance, the women painters stood a greater chance of attracting art curators and collectors to view their works.Therefore, in 1940, with the Beaver Hall painters’ support of each other, Seath joined a four-woman show with Prudence Heward, Sarah Robertson, and Anne Savage at the Art Gallery of Toronto.She took part in several more group exhibitions, one in 1944 (December 4-30) at the Art Association of Montreal, another in 1945 at the Willistead Art Gallery, as well as a daunting six-woman show in 1950 (May 3-24) at the Montreal Museum of Fine Arts, Gallery XII.
