Justices of the Supreme Court of Canada are appointed by the Governor General-in-Council, a process whereby the governor general, the viceregal representative of the Queen of Canada, makes appointments based on the advice of the Queen's Privy Council for Canada. By tradition and convention, only the Cabinet, a standing committee in the larger council, advises the governor general and this advice is usually expressed exclusively through consultation with the prime minister. Thus, the provinces and Parliament of Canada have no formal role in such appointments, sometimes a point of contention.
