Officially known as the Canadian Forces 431 Air Demonstration Squadron, the Snowbirds are Canada's military aerobatics or air show flight demonstration team whose purpose is to "demonstrate the skill, professionalism, and teamwork of Canadian Forces personnel". The squadron is based at 15 Wing, near Moose Jaw, Saskatchewan. The Snowbirds are the first Canadian air demonstration team to be designated as a squadron. Although the CL-41 Tutor has been retired from active training, 22 Tutors continue to fly with the Canadian Forces Snowbirds and the Aerospace Engineering Test Establishment at CFB Cold Lake. A number of airframes are held in reserve for future deployment as replacement Snowbird aircraft.
