Figure 10-5: Overview of the acquisition process in Canada
The DND Investment Plan Framework forms the basis of planned capital expenditure, informed by the DND Campaign Plan and Strategic Capability Roadmap.
Approvals are sought from Cabinet and/or the Treasury Board (a statutory cabinet committee). Cabinet approval is generally required where an acquisition raises regional, economic, industrial, or policy issues and where its expenditures exceed $100 million (Major Crown Project)147 148. The Minister of National Defence sponsors the Major Crown Project in Cabinet and at Treasury Board.
Ultimately, once fully approved, DND takes on overall responsibility for managing project implementation (aided by PWGSC and IC staff) until project completion.
