National Defence Headquarters (Canada)

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.

[1] During the Cold War, the threat of nuclear attack on the National Capital Region saw an Emergency Government Headquarters constructed 30 km west of Ottawa at CFS Carp; this facility was to house a scaled-down NDHQ, along with the federal cabinet and other political, military and government leaders.

Completed in 1974, the George R Pearkes Building was originally built for Transport Canada, until a plan for a new NDHQ in LeBreton Flats was cancelled.

Transport Canada instead moved to the newly completed Place de Ville Tower C (1972).

Carling Campus was originally Nortel's research and development site, until it was purchased by the Federal Government in 2010.
