Hoping someone can help.

Is there anyway of checking where and when a pilot carried out his pilot training in Canada. Flight Lieutenant Peter Francis Dunham DFC 42957 RAF carried out his first tour as an airgunner on No.214(B) Squadron, his second tour as an Observer with No.218(B) Squadron. He then was posted to Canada to carry-out pilot training returning for a third tour with No.218(B) squadron in October 1944.

Any help or pointers welcome
