NMSO (National Master Standing Offer)

A National Master Standing Offer is a standing offer established for use by eligible federal users across all of Canada, rather than in a single region. It is an offer from a supplier to provide goods or services at pre-arranged prices — not a contract — and it becomes a contract only when an identified user issues a call-up against it.

What it is

Per Public Services and Procurement Canada's standing offer records, an NMSO authorizes identified users to make call-ups against the standing offer, and for a national master standing offer those users typically include any government department, agency or Crown corporation listed in Schedules I, I.1, II or III of the Financial Administration Act. That breadth is what separates an NMSO from a regional standing offer: one competition, pre-arranged prices, and a national scope — often paired with an electronic catalogue the identified users order from. NMSOs are commonly used for frequently ordered, commercially available commodities, such as aviation fuel or travel services, and some NMSOs also extend to organizations eligible under the Canadian Collaborative Procurement Initiative.

Call-up limits

The call-up limit is not one-size-fits-all: it is written into each NMSO. A common ceiling is $249,999.99 (applicable taxes included) per individual call-up, as seen in PSPC's air charter NMSO, while other NMSOs set different limits — the into-plane aviation fuel NMSO authorizes users to issue call-ups up to $1 million, with the PSPC standing offer authority handling anything above. When a requirement exceeds the stated limit, the identified user must seek an increase from the Standing Offer Authority or route the call-up through PSPC, and call-ups are documented on the PWGSC-TPSGC 942 form, Call-up Against a Standing Offer.

What it means for vendors

Winning an NMSO positions your firm in front of buyers across the federal system for the offer period, but revenue only arrives one call-up at a time, and buyers may direct a call-up to any offeror in the NMSO. You remain bound by the prices and terms in your offer for the full period, so pricing discipline matters: you cannot raise rates mid-period just because demand spikes. Monitor the offer period and refresh cycles — standing offers lapse when the period ends, and being an incumbent does not carry over automatically into the next solicitation.

Common questions

Is an NMSO a contract?

No. A standing offer is an offer from your firm to supply at set prices. Each call-up issued under it is an individual contract, subject to the call-up limit and the terms of the standing offer.

How is an NMSO different from a supply arrangement?

A standing offer fixes your prices in advance and lets users order directly by call-up. A supply arrangement only pre-qualifies you to bid — each requirement under a supply arrangement still needs a competitive solicitation before any contract is awarded.
