Strategy Page looks at a recent mini-scandal when it was noted by Canadian media types that the Royal Canadian Air Force was — shock! horror! — actually recruiting foreign pilots:
Canada has a long history of allowing foreigners to join its armed forces. This happened on a large scale with Americans in the years before the United States entered World War I and World War II. But Australians and British recruits continue to be welcomed, as well as those from other parts of the old British Empire.
The big advantage of recruiting foreign pilots in the last five years was the need to obtain experienced personnel with lots of flying time in aircraft (like transports) Canada was operating all over the world. Canada has lost a lot of their experienced pilots for these aircraft to retirement or more attractive offers from commercial airlines. The incentive for British military pilots was keeping some of the high rank and credit for time already served in the British military. The British recruits will also be able to become Canadian citizens quickly, which is what many British citizens have been doing regularly since Canada became independent in 1867.
The RCAF also reminded the media that it has long used foreign pilots, often as instructors, on a “loan” program. The foreign country continued to pay the salary of their pilot but the RCAF picked up all other expenses while the foreign (often American) pilot was working in Canada. The loaner pilots are most frequently used when Canada is buying a new type of aircraft and needs pilots experienced with the new aircraft in order to speed the training of Canadian pilots.
