A deputy of the governor general (French: gouverneur général suppléant)[1] is, per the Constitution Act, 1867,[2] one of any individuals appointed by the governor general of Canada, with the Canadian monarch's consent, to act in their stead, exercising any powers so delegated to them by the governor general—generally all save for dissolving Parliament,[3] granting royal assent, signing orders in council, issuing royal proclamations, or receiving the credentials of newly appointed ambassadors to Canada.[4]
Currently, the secretary to the governor general, the deputy secretary to the governor general, and the justices of the supreme court are called upon to act as deputies of the governor general;[5] when the latter are acting in this capacity, they are addressed as The Honourable the Deputy of Her Excellency the Governor General.[4] The deputy's commission will read as follows:
KNOW YOU that being well assured of your loyalty, fidelity and capacity, I, the Right Honourable [Name], Governor General of Canada, under and by virtue of and in pursuance of the power and authority vested in me by the Commission of His Majesty King Charles III, under the Great Seal of Canada, dated the [day] of [month] in the year of Our Lord [year], constituting and appointing me to be Governor General of Canada do hereby nominate, constitute and appoint you, [Name], to be my Deputy within Canada and in that capacity to exercise, subject to any limitations or directions from time to time expressed or given by His Majesty, all the powers, authorities and functions vested in and of right exercisable by me as Governor General, saving and excepting [any powers excluded from the delegation, which will include, at a minimum,the power of dissolving the Parliament of Canada].[4][failed verification]
