Hamilton Gault Barracks Memorial Gate was officially opened on the evening of 16 September 1964 by Mrs. Dorothy Hamilton Gault, widow of the Founder of Princess Patricia’s Canadian Light Infantry, Brigadier A. Hamilton Gault, DSO, ED, CD. The gate was financed and sponsored by the Princess Patricia’s Canadian Light Infantry Jubilee Wives’ Club.

The gate was damaged in 1968, removed, repaired and shipped to Calgary. It was returned to Edmonton in 1971 and raised back into position by the Canadian Airborne Regiment. The gate was again damaged, this time irreparably and was replaced by the Hamilton Gault Memorial Cairn.
