The Government of Canada (French: Gouvernement du Canada), officially Her Majesty's Government (French: Gouvernement de Sa Majesté), is the federal administration of Canada. In Canadian English, the term can mean either the collective set of institutions or specifically the Queen-in-Council. In both senses, the current construct was established at Confederation through the Constitution Act, 1867—as a federal constitutional monarchy, wherein the Canadian Crown acts as the core, or "the most basic building block", of its Westminster-style parliamentary democracy. The Crown is thus the foundation of the executive, legislative, and judicial branches of the Canadian government. Further elements of governance are outlined in the rest of the Canadian Constitution, which includes written statutes, court rulings, and unwritten conventions developed over centuries.The monarch (currently Queen Elizabeth II) is personally represented by the Governor General of Canada (currently Julie Payette). The Queen's Privy Council for Canada is the body that advises the sovereign or viceroy on the exercise of executive power. However, in practice, that task is performed only by the Cabinet, a committee within the Privy Council composed of ministers of the Crown, who are drawn from and responsible to the elected House of Commons in parliament. The Cabinet is headed by the prime minister (currently Justin Trudeau), who is appointed by the governor general after securing the confidence of the House of Commons.
