In 1970 Sullivan walked from the Musée d’art contemporain de Montréal, then located at Cité du Havre, to the Musée des beaux-arts de Montréal on Sherbrooke Street. In the 1970s many artists were questioning the role of art and its commodification. Although Sullivan agreed with this position, she was uncomfortable when artists suggested museums were no longer needed. Her response was to move away from sculpture, but to maintain her appreciation of museums as places where art ideas could be developed and appreciated.
