The King's Privy Council for Canada, sometimes called His Majesty's Privy Council for Canada or simply the Privy Council (PC), is the full group of personal consultants to the monarch of Canada on state and constitutional affairs. Practically, the tenets of responsible government require the sovereign or his viceroy, the governor general of Canada, to almost always follow only that advice tendered by the Cabinet: a committee within the Privy Council composed usually of elected members of Parliament. Those summoned to the KPC are appointed for life by the governor general on the advice of the prime minister of Canada, meaning that the group is composed predominantly of former Cabinet ministers, with some others having been inducted as an honorary gesture. Those in the council are accorded the use of an honorific style and post-nominal letters, as well as various signifiers of precedence.

Responsible government is a conception of a system of government that embodies the principle of parliamentary accountability, the foundation of the Westminster system of parliamentary democracy. Governments in Westminster democracies are responsible to parliament rather than to the monarch, or, in a colonial context, to the imperial government, and in a republican context, to the president, either in full or in part. If the parliament is bicameral, then the government is responsible first to the parliament's lower house, which is more representative than the upper house, as it usually has more members and they are always directly elected.
