In August 1945, after a period on operational staff duties, during which he managed to fly a few more operations in Spitfires, Fox returned to Canada. He was released from the RCAF a month later. In the peace that followed he joined the RCAF Auxiliary and served with No 420 Reserve Squadron flying Harvards, Mustangs and the early jet fighters. He later transferred to fighter controller duties, finally completing his service in May 1961. Fox was appointed an honorary colonel with 412 Squadron in April 2004, and presented with a painting by Lance Russwurm of his Spitfire attacking Rommel's car.
