The home based squadrons are overshadowed by the 400-block squadrons. Though some of the home based squadrons were transferred overseas to become 400-block squadrons, most remained in Canada performing a multitude of tasks. Several home based squadrons were involved in active combat and many others helped protect Canada's sea coasts.
Because of the large number of Dominion squadrons which were to be formed in the United Kingdom under RAF control, and to avoid confusion with low-numbered RAF squadrons, the British Air Ministry assigned the numbers 400-445 to Canadian squadrons in the UK. After the war the RCAF continued to use the wartime squadron codes in the 400 series. In the early sixties Australia which had been given the codes 446 - 467 released squadrons 446 - 450 to the RCAF.
There have also been other units/squadrons in the RCAF and Canadian Air Force. These units may have comprised units organized for special duties ie/ 115 and 116 Flights which flew Caribou and Otter aircraft on Middle East Peacekeeping duties, the also included holdover squadrons after unification like VU 32 and VU 33 which were holdover naval units. Unfortunately not much has been written about these units and we would appreciate any help anyone could provide on a short operational history of many of these units.
