51 Aerospace Control and Warning (AC&W) Squadron was originally formed in Comox, BC, in November 1954 and disbanded in June 1958. Re-formed at North Bay in 1989, 51 AC&W Sqn became one of 22 Wing’s three units. 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.
