Client Departments and Agencies

"Client departments and agencies" is standard Canadian federal government usage. It refers to the federal organizations that receive services from a central service provider, or that use instruments the provider has put in place for them. In procurement, the provider most often named is Public Services and Procurement Canada (PSPC), and the clients are the departments and agencies that need goods and services to carry out their mandates.

PSPC describes its own role in these terms. Its mandate page says the department supports federal departments and agencies in achieving their mandated objectives, and it names added value for its client departments and agencies as a goal. For a supplier, the phrase identifies who the government buyer or end user is, which is not always the same as who runs the procurement.

How PSPC uses the term as central purchasing agent

PSPC describes itself as the central purchasing agent for federal departments and agencies. In its briefing material for the Standing Committee on Government Operations and Estimates, PSPC states that it puts contracts in place on behalf of client departments and agencies.

PSPC also sets up shared instruments. According to its briefing material for the Standing Committee on Public Accounts, it establishes and administers standing offers and supply arrangements that client departments and agencies can access directly. That gives clients two routes: PSPC can run a procurement for them, or they can buy through a PSPC instrument within the limits of that instrument and their own authorities.

The scale of the client base

PSPC's deputy minister transition material states that the department supports more than 140 federal client departments and agencies. The group is large and varied, and it covers organizations with very different mandates and purchasing needs.

Use of the term outside PSPC

PSPC is not the only organization that uses the phrase. Justice Canada refers to the federal organizations it provides legal services to as client departments and agencies, as shown in its 2026-27 departmental plan material. The phrase also appears in descriptions of other shared government services, such as accounting, treasury and real property.

A Justice Canada evaluation page lists the clients supported in its Public Safety, Defence and Immigration portfolio:

• Public Safety Canada
• Canada Border Services Agency
• Canadian Security Intelligence Service
• Royal Canadian Mounted Police
• Correctional Service Canada
• Parole Board of Canada
• Department of National Defence and the Canadian Armed Forces
• Communications Security Establishment

A procurement example: ArriveCAN

PSPC's committee briefing material shows the arrangement in practice. PSPC provided procurement support to the Canada Border Services Agency to procure professional services used for several purposes, including the development of the ArriveCAN application. The agency was the client with the requirement, and PSPC supplied the procurement support.

What it means for a supplier

When a solicitation or contract refers to a client department or agency, treat that organization as the government client or end user. Then check the solicitation documents to see who the contracting authority is. PSPC may be running the procurement on the client's behalf, or the client may be buying directly through a PSPC standing offer or supply arrangement.

This affects who you address with questions, who evaluates your bid and who manages the resulting contract. It also affects which instrument you need to be on to reach a particular client. Reading the client and the contracting authority separately lets a bid team target the right organization at each stage.
