The Military History Research Centre's oral history archive contained nearly 400 interviews in 2007. The oral history collection was started by the museum in 1999. The program devised topic lists to guide interviews towards certain areas of interests; although the framing of the topics are designed to allow for in-depth conversation, one free of bias. Interviews were either conducted by the museum's research team, or ex-military officers, and averaged 90 minutes in length. Subjects of interviews includes service members who served in the Second World War, United Nations Emergency Force, Canadian Forces Europe, Yugoslav Wars, and the War in Afghanistan. Specific subjects interviewed include Airborne Intercept Navigators in NATO and NORAD, deputy commanders of NORAD, and all former Canadian commanders of STANAVFORLANT.
