How do you get a record of Canadian Air Force Personnel?

If you are that person, you apply to Veteran's Affairs. They willl supply you with the record.

If you are asking about a current surving RCAF member (and you are not that person) or on who is still alive, you don't. Canada has strict privacy laws that prohibit you from access someone's records.

If you are related to an RCAF member who has died, and can prove it, you can apply via Veteran's Affairs. They may be able to supply you with the records.

Otherwise go to Collections Canada and do a search. Some records are available to the public. You will recieve the enlistment papers, but will have to pay to see the rest.
