In addition to the monument at its head office in Toronto, the Canadian Bank of Commerce honoured employees from each branch who served in the First World War. This plaque was commissioned shortly after the war and dedicated to the bank's 1701 employees who served in the war, 321 laid down their lives. The names of 21 employees of the Ottawa Canadian Bank of Commerce who served in the war are listed on the plaque. This plaque was erected when this CIBC building was first opened to the public – January 1922.
The plaque features the caduceus logo of the bank - two snakes winding around a winged staff at the upper left, and three poppies intertwined with a symbolic olive branch at the base of the staff. The Canadian Bank of Commerce went to great lengths to commemorate its staff that served in the war including a two-volume book of staff profiles and accounts of their war experiences.
