Thomson was posted to 20 Squadron RFC on1918-03-28. He ended the war as one of the highest scoring two-seater pilots with 26 victories. He was de-mobbed and returned to Canada early in 1919 and returned also to Lachine Quebec where he died in 1986.
I cannot, however, find anything about him post WWI, including a burial place.
