As a memorial to staff who gave their lives in the Great War, the Bank of Nova Scotia commissioned about 60 bronze tablets, between July 1920 and February 1921, to be placed on the wall of the branch where each known staff member was employed when they joined the military forces. These plaques listed the names of staff killed on the field, as well as those who died from their wounds after they returned home from the war.

This plaque honours Duncan MacPherson and Andrew Edward Hector Hugh MacKay former officers of the Bank of Nova Scotia Main Branch in Calgary, Alberta, who were was killed in service during the Great War.
