For practical reasons, the Cabinet is informally referred to either in relation to the prime minister in charge of it or the number of ministries since Confederation.
However, the Privy Council—composed mostly of former members of parliament, current and former chief justices of Canada, and other elder statesmen—rarely meets in full; as the stipulations of responsible government require that those who directly advise the monarch and governor general on how to exercise the Royal Prerogative be accountable to the elected House of Commons, the day-to-day operation of government is guided only by a sub-group of the Privy Council made up of individuals who hold seats in Parliament.
In the context of constitutional monarchy and responsible government, the ministerial advice tendered is typically binding; though, it is important to note that the royal prerogative belongs to the Crown, not to any of the ministers,[6][7] and the royal and viceregal figures may unilaterally use these powers in exceptional constitutional crisis situations.

Members of the Cabinet receive assistance from both parliamentary secretaries—who will usually answer, on behalf of a minister, questions in the House of Commons—and deputy ministers—senior civil servants assigned to each ministry in order to tender non-partisan advice.
Combined with a comparatively small proportion of bills originating with individual members of Parliament, this leads to Cabinet having almost total control over the legislative agenda of the House of Commons.

"[40] John Robson criticised the use of the prime minister's name to identify the Cabinet, calling it a "bad habit" that "endorses while concealing the swollen pretension of the executive branch.
