The City of Gatineau corresponds entirely to the territory of the City of Gatineau. It differs from other RCMs in the Outaouais in that it is made up of a single municipality, which assumes both municipal responsibilities and the regional powers typically assigned to RCMs.
Its territory includes the sectors of Aylmer, Hull, Gatineau, Buckingham, and Masson-Angers, resulting from the 2002 municipal merger. This unified structure gives Gatineau expanded capacity for regional planning and management.
