Canada East. Office of Deputy Adjutant General : The first Militia Act for United Canada (9 Vict. Cap. 28), passed in 1846, provided for the appointment of a Deputy Adjutant General in Canada East who was to assist the Adjutant General. The Deputy Adjutant General in Lower Canada (the old provincial name was retained within the militia) had the power to issue Militia General Orders, to grant commissions, as well as the responsibility for the organization, training, management and discipline of the militia. The Deputy Adjutants General in Lower Canada and Upper Canada, and their small staffs, were the only full-time officers in United Canada. As the office of the Adjutant General of Militia was often vacant for lengthy periods, the Deputy Adjutants General were frequently responsible for looking after militia matters in their respective halves of the Province.
