Canadian sovereignty in the context of "Canadian provinces"

The monarchy of Canada is Canada's form of government embodied by the Canadian sovereign and head of state. It is one of the key components of Canadian sovereignty and sits at the core of Canada's constitutional federal structure and Westminster-style parliamentary democracy. The monarchy is the foundation of the executive (King-in-Council), legislative (King-in-Parliament), and judicial (King-on-the-Bench) branches of both federal and provincial jurisdictions. The current monarch is King Charles III, who has reigned since 8 September 2022.

Although the sovereign is shared with 14 other independent countries within the Commonwealth of Nations, each country's monarchy is separate and legally distinct. As a result, the current monarch is officially titled King of Canada and, in this capacity, he and other members of the royal family undertake public and private functions domestically and abroad as representatives of Canada. However, the monarch is the only member of the royal family with any constitutional role.

Patriation is the political process that led to full Canadian sovereignty, culminating with the Constitution Act, 1982. The process was necessary because, at the time, under the Statute of Westminster, 1931, and with Canada's agreement, the British Parliament retained the power to amend Canada's British North America Acts and to enact, more generally, for Canada at the request and with the consent of the Dominion. That authority was removed from the UK by the enactment of the Canada Act, 1982, on March 29, 1982, by the Parliament of the United Kingdom, as requested by the Parliament of Canada.

A proclamation bringing the Constitution Act, 1982, into effect was signed by Elizabeth II, as Queen of Canada, Prime Minister Pierre Trudeau, and Minister of Justice Jean Chrétien on April 17, 1982, on Parliament Hill in Ottawa. The patriation process saw the provinces granted influence in constitutional matters and resulted in the constitution being amendable by Canada only and according to its amending formula, with no role for the United Kingdom.

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.
