Long before the arrival of the first European settlers, Canada's Aboriginal peoples had discovered the edible properties of maple sap. In 1860, at a public meeting held in Toronto, the maple leaf was adopted as the national emblem of Canada for use in the decorations for the Prince of Wales' visit. Red and white were designated as Canada's official colours in 1921 by His Majesty, King George V, in the proclamation of the Royal Arms of Canada.
During the First World War, badges of the Canadian Expeditionary Force were often based on a maple leaf design. The use of the maple leaf as a regimental symbol extended back to the 1800s, and Canadian soldiers in the Second Boer War were distinguished by a maple leaf on their sun helmets.
