National Defence Headquarters (NDHQ) (French: Quartiers généraux de la Défense nationale (QGDN)) was created through the integration of the Canadian Armed Forces Headquarters (CAF HQ) with the civilian Department of National Defence (DND) staff in October of 1972. NDHQ is not a specific location, but is instead housed throughout a collection of offices in buildings across the National Capital Region, although it is most commonly identified with the Major-General George R Pearkes Building on Colonel By Drive in Ottawa.
From 2017, various locations have been consolidating at National Defence Headquarters, Carling Campus on Carling Avenue.[1]
