History of Diefenbunker: Canada’s Cold War Museum
Commissioned during the height of Cold War tensions between NATO and the Soviet Union, the bunker was constructed from 1959 to 1961 as Canadian Forces Station Carp. It served as a top-secret underground fortress housing the Prime Minister, war cabinet members, and essential military and government staff. Designed to support 535 people for 30 days straight, the Diefenbunker was equipped with offices, living quarters, kitchens, communication centres, and emergency supplies.
Though it never had to serve its emergency role, the bunker was fully operational until being decommissioned in 1994 following the end of the Cold War. In 1998, a local group and volunteers transformed the complex into a museum to preserve Canada’s Cold War heritage. Now, it serves as an immersive learning space exploring the global political tensions, military technology, and human stories from that fraught period.
