51 Aerospace Control and Warning Operational Training Squadron is a Royal Canadian Air Force unit based at 22 Wing/CFB North Bay. It is responsible for all operational and general training at 22 Wing. Operational and conversion training for RCAF personnel destined to work in the Canadian Sector Air Operations Centre (SAOC) is provided by the squadron.[1]

In July 1994, the role of the squadron changed to an Operational Training (OT) squadron and it is now responsible for all operational and general training at 22 Wing.
