Data through November 2026. Source: Publicus analysis of CanadaBuys and federal proactive disclosure records (CPD build ur-20261108T082027Z).
Method: Federal contracts signed from 2021-04-01 to 2026-03-31, grouped by the department that owns the requirement and by fiscal year (April to March) of the signing date. Each contract's value counts once: its latest amended value as published, in Canadian dollars. Standing-offer ceilings, undisclosed amounts and unverified amounts above $1 billion are not counted, and a CanadaBuys copy of a contract the department also disclosed is counted once. Suppliers that Publicus does not name are left out of the top-supplier lists.
The other 85 departments and agencies signed $342.8 million together. 22,867 contracts signed in the window had no countable value and are not in these totals. A dash means no counted contract value that year.
Reading the ranking
Contract value follows mandate. The departments at the top look after large assets and government-wide services: ships, aircraft and equipment, federal buildings, and the networks and data centres other departments run on. A department lower on the list can still be the largest buyer in its own field, and the yearly columns matter as much as the total, because a single large contract can lift one fiscal year well above the others.
For a supplier, the ranking is a way to size where federal demand sits before choosing which buyers to get to know, and each department's page shows what it contracts for and who it already works with. For a public servant, it is a plain view of how a department's contracting compares with its peers, useful when planning a requirement, benchmarking a program's contracting or explaining the numbers in a briefing.
Every figure comes from records departments publish themselves. Browse every federal buyer or see contracts by category.
