The final gallery, "From the Cold War to the Present", explored Canada's role during the Cold War, and the threat of nuclear war in the public eye. In 2017, the concluding portion of the fourth gallery was updated to include post-Cold War conflicts involving members of the Canadian Armed Forces. The final portion of the gallery was designed to confront visitors with the problematic nature of warfare; and features an interactive space for visitors to leave their own reflections on war, peace, and remembrance.
