DND (Department of National Defence)

DND is the standard abbreviation for the Department of National Defence, the federal department responsible for defence policy, military capabilities and support to the Canadian Armed Forces (CAF). The department uses the abbreviation in its own procurement material, including its published defence purchases and upgrades process.

In procurement, DND appears as a buyer, as an end user and as the client on whose behalf another department contracts. It works with the CAF, Public Services and Procurement Canada (PSPC) and Innovation, Science and Economic Development Canada (ISED) to acquire equipment and services. Suppliers who read DND notices correctly can tell which organization runs the solicitation and which one will manage the resulting contract.

How DND and PSPC divide defence buying

DND conducts some procurement under its own contracting authority. PSPC also buys goods and services for DND using federal tools such as Standing Offers and Supply Arrangements, as described in the 2025-2026 DND public safety annual report.

The two departments share an agreed procurement responsibility matrix, published on CanadaBuys under agreements with the Department of National Defence. The matrix sets out which department acquires which categories of goods and services.

Naming DND as the client does not make a contract a defence contract. CanadaBuys treats the client department and the classification of the contract as separate questions in its guidance on defence contracts and defence supplies.

DND's role in the Defence Procurement Strategy

DND is one of four core federal departments in the Defence Procurement Strategy, alongside PSPC, ISED and the Canadian Coast Guard. Under the strategy, DND identifies military capability requirements, develops specifications, assesses options and costs, obtains policy and funding approvals, and provides technical expertise and integration support. PSPC describes these duties on its defence procurement strategy page.

DND follows a five-stage process to acquire military equipment and services that address CAF capability deficiencies or emerging requirements. The department sets out each stage in its defence purchases and upgrades process.

Urgent requirements, task authorizations and routine contracts

DND uses several mechanisms beyond large capital projects:

• Urgent Operational Requirements (UOR): DND can procure essential equipment on an accelerated timeline, as noted in its procurement background notes.
• Routine, low-value contracts: DND administers the award of these contracts. It also manages the performance of all DND contracts, including those awarded on its behalf, according to its audit of contract amendments.
• Task-authorization contracts: CanadaBuys lists a contract titled DND Engineering and Manufacturing Services, which supported engineering and research-and-development requirements through task authorizations.
• Standing Offers and Supply Arrangements: DND buys through these PSPC tools as well as under its own authority.

DND's supply chain also relies on NATO systems. It includes approximately 1.2 million NATO Stock Numbers (NSNs), according to the 2025-2026 annual report.

What DND means for a supplier bidding on Canadian public contracts

Start by working out DND's role in the opportunity. DND may be the buying department, the end user, or the client for a PSPC solicitation. Then confirm who issues the solicitation and which contracting vehicle it uses: a Standing Offer, a Supply Arrangement, a task authorization or a competitive bid.

Check the requirement type, whether goods, services, engineering, research and development, sustainment or an urgent need. Look for defence-specific conditions such as an NSN, technical specifications or security requirements. The abbreviation DND does not by itself create a certification or compliance obligation. Take those obligations from the individual solicitation and contract documents.
