The Department of Militia and Defence was responsible for Canadian Army purchases and the Department of Naval Service, for those of the Royal Canadian Navy (RCN).2 The early months of the war, however, revealed serious deficiencies in the defence procurement process in place. [...] The powers of the War Supply Board extended beyond those of the Defence Purchasing Board and included the mobilization and organization of Canadian industry for the war effort. [...] The new department was responsible for planning, acquiring, and supplying the goods and services required by all federal government departments and agencies, including DND and the armed forces.27 6.4.2 THE DEPARTMENT OF NATIONAL DEFENCE (MATERIEL GROUP) The Glassco Commission also ushered in a period of reform and reorganization for DND and the armed forces.
