The coat of arms of Canada, also known as the Royal Coat of Arms of Canada or, formally, as the Arms of His Majesty The King in Right of Canada, is the arms of dominion of the Canadian monarch and, thus, also the official coat of arms of Canada. In use since 1921, it is closely modelled after the royal coat of arms of the United Kingdom, with French and distinctive Canadian elements replacing or added to those derived from the British version.
The maple leaves in the shield, blazoned "proper" (i.e., in natural colour), were originally drawn vert (green), but were redrawn gules (red) in 1957 and a circlet of the Order of Canada was added to the arms for limited use in 1987. The arms are registered with the Canadian Heraldic Authority and protected under Crown copyright; they are used to signify national sovereignty and the federal government uses the arms to represent the state under the Federal Identity Program. Elements of the coat of arms are also used in other designs, with the shield being used in the various royal standards belonging to members of the royal family and the crest of the arms serving as the focal point of the governor general's flag.
