About Canada’s Cold War Museum

The Diefenbunker is a massive four-story underground bunker, built between 1959 and 1961. During the Cold War, top officials were to take shelter here in the event of a nuclear war. It was active as Canadian Forces Station Carp until 1994.

Today, it operates as a not-for-profit, charitable museum with award-winning tours and programs.

Let’s learn more about the Diefenbunker from home with our collection of online activities and resources. You can explore:

If you have questions, let’s connect on Facebook, Instagram, or Twitter. We will happily answer any of your questions.

About the Cold War

The Cold War is the period between the end of the Second World War in 1945 and ends with the fall of the Berlin Wall in 1989, followed by the collapse of the Soviet Union in 1991. It was a period of tense conflict between the United States and the Soviet Union and each country’s respective allies.

Learn more in this 2-minute video from Historica Canada explaining the Cold War and Canada’s role.

The Machine Room Virtual Tour

Did you know?

The bunker ran on hydroelectric power during its years of operation, much like it is today. In the event of a lockdown situation it was important that the bunker continued to be powered.
The machine room had 4 diesel generators to power the bunker. Only 2 generators were required to keep the bunker powered in an outage. The first generator would provide power to communications only. The second was to provide power to the rest of the bunker.

Click on the image to learn more about the machine room and all its functions. We also interview one of the employees who worked in the machine room.
