The following is a list of the governors and governors general of Canada. Though the present-day office of the Governor General of Canada is legislatively covered under the Constitution Act, 1867 and legally constituted by the Letters Patent, 1947, the institution is, along with the institution of the Crown it represents, the oldest continuous and uniquely Canadian institution in Canada, having existed in an unbroken line since the appointment of Samuel de Champlain in 1627.^[1]

Following the Seven Years' War, control passed from France to Great Britain in the terms of the Treaty of Paris, creating the British Province of Quebec. Governors subsequently served under the British monarchy.
