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.
It's believed that the maple leaf became a Canadian symbol as early as the 1700's. Indians have been using the sap of the trees for food long before Canada saw ships on its horizon. Several groups used the Maple Leaf as a symbol in the 1800's, including its use on the badge of the 100th Regiment. The same year (1860) it was used as a decorative theme for the Prince of Wales visit. Alexander Muir wrote The Maple Leaf Forever in 1867 as a song for Confederation.
