The Dennis Tourbin Members Gallery (DTMG) was created in 1996. It was named after a founding member of NAC, renowned for his charisma, wit, and energy. After playing a key role in the establishment of NAC and in the successes of early NAC projects like the Johnny Canuck Miniature Show, and the Twelve Mile Creek publications, Dennis went on to help found Art Space in Peterborough and later became a key figure at the SAW Gallery in Ottawa. His work has been collected by the National Gallery of Canada.
The DTMG is available for exhibits, installations, performance and screenings by NAC members in good standing. Work in the space can also be made for sale. NAC takes a commission of 15% to help defray costs related to gallery upkeep. It is a do-it-yourself space and all presentations are produced, promoted, and installed by the featured NAC member artist.
