The monarchy of Canada forms the core of each Canadian provincial jurisdiction's Westminster-style parliamentary democracy, being the foundation of the executive, legislative, and judicial branches of government in each province. The monarchy has been headed since 6 February 1952 by Queen Elizabeth II who as sovereign is shared equally with both the Commonwealth realms and the Canadian federal entity. She, her consort, and other members of the Canadian Royal Family undertake various public and private functions across the country. However, the Queen is the only member of the Royal Family with any constitutional role.
