In addition to the BCATP in Canada, there were several out of the norm training schemes going on. For example, the Norwegians trained at Toronto island airport, with a satellite field at Emsdale Ont ( known affectionately as Little Norway). The Royal Navy established a training field at Kingston Ont, and RAF Ferry Command established a facility at North Bay Ont to train pilots and navigations in the art of Trans Atlantic flying, after a successful test around 1940 involving 7 bombers to be ferried from Canada to UK ( using the methodology of the time, it was to be considered a success if at least 4 of the 7 bombers made it- and all 7 did!).
While a hangars and facilities were built at North Bay, it remained a civil airport with no official RCAF or RAF designation until the mid 1950, when the Cold War escalated. While facilities were expanded, it still remained a civil airport, with the now established ATC also being civilian. The added benefit to this was that they were *ahem* a bit more relaxed in their handling of clearances, and many an impromptu airshow resulted!
