Diefenbunker tours lead visitors through a once top-secret facility that includes government offices, living quarters and cryptographic areas.
Can also see the Prime Ministers suite, the War Cabinet Room, the CBC radio studio, the Bank of Canada vault, and the Emergency Government Situation Centre.
Other Cold War paraphernalia on display include a community fallout shelter, a display of Cold War era toys and a special exhibit on Hiroshima and Nagasaki.
At the height of the Cold War in the early 1960s, the Canadian government built a series of Emergency Government Headquarters nicknamed Diefenbunkers by the government opposition as nuclear fallout shelters for government officials.
The largest of these bunkers spanning more than 100,000 square feet is located in Carp, Ontario, just outside of Ottawa.
Today, it has been converted into a public museum.
