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 8 September 2022 by King Charles III who as sovereign is shared equally with both the Commonwealth realms and the Canadian federal entity. He, his consort, and other members of the Canadian royal family undertake various public and private functions across the country. He is the only member of the royal family with any constitutional role.
Royal assent and the royal sign-manual are required to enact laws, letters patent, and Orders in Council. The Constitution Act, 1867, leaves the monarch's direct role in the provinces in question and many royal duties in these regions are specifically assigned to the sovereign's provincial viceroys, known as lieutenant governors, who are appointed by the King's federal representative, the governor general. Further, within the conventional stipulations of constitutional monarchy, the Crown's direct participation in any of these areas of governance is limited, with most related powers entrusted for exercise by the elected parliamentarians, the appointed ministers of the Crown generally drawn from amongst them, and the judges and justices of the peace. The Crown today primarily functions as a guarantor of continuous and stable governance and a nonpartisan safeguard against the abuse of power, the sovereign acting as a custodian of the Crown's democratic powers and representing the "power of the people above government and political parties."
