Go underground on an 11-step guide to surviving the Cold War

  • 01 top secret 533-room underground bunker
  • 100,000 square feet of Cold War history
  • 11 step guide to surviving a nuclear threat

Imagine the worst has happened; a full-scale nuclear attack. Along with elite Canadian government officials, you scramble underground to a secret 100,000 square foot nuclear bunker built during the height of the Cold War between 1959 and 1961. Re-live the eerie sensation and tensions of the Cold War-era, when the threat of nuclear annihilation was imminent.
On this two-hour guided tour, you'll learn to carry out each step of the official 11 Steps to Survival guide issued to citizens by the Canadian Government. Learn about radioactive fallout, how to take shelter, and survive on army rations. Touch 1960s-era typewriters and phones. Have your photo taken in the iconic Blast Tunnel, then be "treated" to your own personal military ration pack. Get comfortable in the Prime Minister's Suite with its single bed - no family allowed. Touch the period operating room, War Room, bank vault and see a full-size replica A-bomb.
