The Constitution Act of 1867 stipulates that Lieutenant Governors are appointed by the Governor General in Council and remain in office "during the Pleasure of the Governor General." The standard term of office is five years. Traditionally, the Prime Minister of Canada consults with his or her provincial counterpart to name the Lieutenant Governor, who is then officially appointed by the Governor General.
