Over time Carr's work came to the attention of several influential and supportive people, including Marius Barbeau, a prominent ethnologist at the National Museum in Ottawa. Barbeau in turn persuaded Eric Brown, Director of Canada's National Gallery, to visit Carr in 1927. Brown invited Carr to exhibit her work at the National Gallery as part of an exhibition on West Coast Aboriginal art. Carr sent 26 oil paintings east, along with samples of her pottery and rugs with Indigenous designs. The exhibit, which also included works by Edwin Holgate and A.Y. Jackson, traveled to Toronto and Montreal.
It was at the exhibition on West Coast Aboriginal art at the National Gallery in 1927 that Carr first met members of the Group of Seven, at that time Canada's most recognized modern painters. Lawren Harris of the Group became a particularly important support: "You are one of us," he told Carr, welcoming her into the ranks of Canada's leading modernists. The encounter ended the artistic isolation of Carr's previous 15 years, leading to one of her most prolific periods, and the creation of many of her most notable works. Through her extensive correspondence with Harris, Carr also became aware of and studied Northern European symbolism.
