How to Sell to the Government of Canada
The federal government is one of the largest buyers in the country, and small businesses win most of its everyday contracts. This is the plain-English path from "never sold to government" to your first federal contract, updated for how the system actually works in 2026.
See the 6-step path →To start selling to the federal government, register as a supplier on SAP Business Network (Ariba) through the CanadaBuys portal, then tag your business with the right commodity codes so federal buyers can find you. From there, search and follow tender notices on CanadaBuys, submit compliant bids, and meet the award conditions if you win. Registering, searching, and bidding are all free — and small businesses win the large majority of the government's lower-value contracts.
Why sell to government at all
Governments are unusually good customers. They pay their invoices, they buy in every category imaginable — from software and consulting to catering, cleaning, translation, and construction — and they buy predictably, year after year. The Government of Canada alone procures on the order of $37 billion a year in goods and services, and a single won contract is often worth far more than a grant, while a standing offer can turn into repeat orders for years.
The myth that government contracting is only for large incumbents is exactly that — a myth. The overwhelming majority of federal requirements are modest in dollar value, and small businesses win the large share of those lower-value contracts. If you have already looked at grants and funding for your business, selling to government is the natural second lane: instead of applying for money to build something, you get paid to deliver something the government already needs.
Grants vs. contracts: two different lanes
They are easy to confuse, but they ask opposite things of you. A grant funds something you want to build; a contract pays you to deliver something the government already needs. The same business can pursue both — here is the difference side by side:
Grants
You apply for money to build something- Fund your project or idea
- Report back on outcomes and how you spent it
- Non-repayable — it is not a sale
- You compete for the money up front
Contracts
They pay you to deliver a requirement- Deliver the government's requirement, to spec
- Get paid for the work, like any customer
- Repeatable — a standing offer can mean years of orders
- You compete on best value or price
The 6-step path to your first federal contract
Here is the whole journey at a glance. The rest of this guide expands each step. None of it costs money — registering, searching, and bidding are all free.
Get your CRA Business Number
You need a Canada Revenue Agency Business Number (BN) tied to your GST/HST account — the same nine-digit number you already use for taxes. You do not need it to search opportunities, but you will need it before a contract can be awarded.
Register on SAP Ariba via CanadaBuys
Create a free supplier account through the CanadaBuys onramp to SAP Business Network (Ariba). Using the CanadaBuys-provided link matters — it adds Public Services and Procurement Canada to your customer list so you can actually see and respond to federal opportunities.
Tag commodity codes (GSIN / UNSPSC)
Complete your profile with the goods-and-services categories that describe your business — the government's GSIN codes, now transitioning to the international UNSPSC system. Accurate codes are what get you matched to relevant tender notices instead of noise.
Find & follow opportunities on CanadaBuys
Search CanadaBuys for open tenders, standing offers, and supply arrangements in your categories, and set up notifications so new ones come to you.
Submit a compliant bid
Read the solicitation's instructions like a checklist and answer exactly what it asks, meeting every mandatory criterion. A technically strong bid that misses one mandatory requirement is disqualified before anyone reads the rest.
Meet award conditions (PBN + any clearance)
Before a contract is awarded you will need a Procurement Business Number (PBN) and, for some contracts, a security clearance. Neither is usually required just to bid.
Start with a small, sub-$40,000 contract — not the perfect big one. Small first wins build the past-performance record that bigger bids demand, and the lower-value end is where the field of competitors is thinnest.
Registering as a supplier in 2026
This is the step that trips up newcomers, because the system changed recently. The old Supplier Registration Information (SRI) system was retired in mid-2026. Today, the front door for federal suppliers is SAP Business Network (Ariba), reached through the CanadaBuys portal.
What to do
- Go to CanadaBuys and use its "register on SAP Ariba" link specifically — not a generic SAP signup — so Public Services and Procurement Canada is attached to your account.
- Build your company profile: the product and service categories you supply, your ship-to address and service locations, and your number of employees.
- Keep your commodity codes accurate and reasonably broad. This is your matching engine; too narrow and you miss work, too broad and you drown in irrelevant notices.
Note that professional-services work can run through its own supplier path (the Centralized Professional Services System), so if you are a consultant you may register there in addition to the main network.
How to actually register on SAP Ariba (and the mistakes that stall it)
The single most important detail: use the CanadaBuys "register on SAP Ariba" link, not a generic SAP Business Network signup. The CanadaBuys onramp is what attaches Public Services and Procurement Canada to your account. Register through a plain SAP link and you end up technically registered but invisible to federal buyers — the most common reason a new supplier "signed up" and then never sees an opportunity.
Then build the profile out fully: the product and service categories you supply, your ship-to address and service locations, and your number of employees. The part that stalls people is the commodity codes (GSIN, transitioning to UNSPSC). Too narrow and relevant notices never reach you; too broad and you drown in irrelevant ones. Treat them as your matching engine, set them deliberately, and revisit them as your offering grows.
Two numbers trip newcomers up. You need a CRA Business Number for tax purposes, but you only need a Procurement Business Number (PBN) before a contract is awarded — not to browse or bid. And consultants can register separately through the Centralized Professional Services System (CPSS) in addition to the main network, which is where a lot of professional-services work is sourced.
Where the opportunities are
CanadaBuys (canadabuys.canada.ca) is the single official place where all federal tender notices, standing offers, and supply arrangements are published. If it is a federal opportunity, it is there. Larger requirements are posted openly; smaller "low-dollar-value" purchases can be sourced more directly by a contracting officer, which is one reason relationships and a complete supplier profile matter.
Source: CanadaBuys (canadabuys.canada.ca), the Government of Canada's official tendering service.The important caveat: CanadaBuys is federal only. It does not carry provincial, territorial, municipal, or the "MASH" sector (municipalities, academic institutions, schools, hospitals). Those run through a scatter of separate portals — provincial systems like BC Bid and SÉAO, plus commercial aggregators. That fragmentation across levels of government is exactly the kind of problem GrantCompass exists to solve, and it is where we are heading next (see the note further down).
Register and tag your commodity codes before you have a specific bid in mind. It is free, it takes an afternoon, and it is what puts standing-offer invitations and the new set-aside streams in front of you — instead of leaving you to hunt for them by hand.
Contracts, standing offers & supply arrangements
Not every opportunity is a one-off contract. Two vehicles are worth understanding early because they are how a lot of repeat government work actually flows:
| Vehicle | What it is | Why it matters to you |
|---|---|---|
| Standing Offer | A pre-arranged price and terms the government can "call up" when it needs the goods or service. Not a contract until a call-up is issued. | Get on one and you can receive orders repeatedly with no new competition each time. |
| Supply Arrangement | A pre-qualified pool of suppliers. The department then runs a smaller competition among the pool for each actual job. | Being in the pool is your ticket to bid on a stream of future work others can't see. |
The one-line way to remember it: a standing offer is a pre-set price you just call up; a supply arrangement is a pre-qualified pool that still competes for each job. We break down every solicitation type — RFP, RFQ, ITT, RFI, and the rest — in the companion guide: Government contract types explained.
Set-asides & the new SMB program
Some contracts are reserved for specific kinds of business, which can work strongly in a small firm's favour:
FY2023–24 reached about $1.24B — 6.1%, above the mandatory minimum.
over five years for the Small & Medium Business Procurement Program, launching 2026 — it reserves contract streams for Canadian SMBs. Not a cash grant.
Indigenous business
The Procurement Strategy for Indigenous Business (PSIB) supports a mandatory target that at least 5% of the value of federal contracts go to Indigenous businesses. In 2023–24 that reached about $1.24 billion (6.1%). If your business qualifies and is listed in the Indigenous Business Directory, this is a meaningful advantage. (A broader modernization of this strategy is planned for 2027.)
The new Small and Medium Business Procurement Program
Announced in Budget 2025 and funded at $79.9 million over five years, the Small and Medium Business Procurement Program is a dedicated on-ramp for Canadian SMBs, launching in 2026. It is not a cash grant — it reserves streams of contracts for smaller Canadian businesses, provides navigation support, and gives Canadian content extra weight in evaluation. The practical takeaway: register and get your commodity codes right now, so you are notified as these set-aside streams open.

Many contracts need no clearance at all. When one does — because the work touches protected or classified information, assets, or sites — it is handled through the Contract Security Program (CSP), run by Public Services and Procurement Canada.
Two things ease the worry for newcomers: for federally led processes you generally have until contract award to obtain the clearance rather than needing it at bid closing, and a provisional clearance is available to Canadian organizations for the bidding stage. So a security requirement should rarely stop you from bidding — it is a step you complete if you win.
The Buy Canadian shift (2025–2026)
The rules recently tilted toward domestic suppliers. Under the Policy on Prioritizing Canadian Suppliers and Canadian Content in Strategic Federal Procurements, effective December 2025 and broadened in June 2026, being a genuine Canadian supplier is now a scoring advantage on larger strategic-sector procurements — not through excluding foreign bidders, but via evaluation credits for Canadian suppliers and Canadian content.
Source: Policy on Prioritizing Canadian Suppliers and Canadian Content (effective December 2025, broadened June 2026).For most small everyday contracts this mid-market policy is not the main lever — the forthcoming SMB program matters more to you — but the direction of travel is unmistakably in favour of Canadian small businesses. We cover exactly how it works, and who it helps, in Buy Canadian Policy: what it means for small businesses.
Common first-timer mistakes
- Treating a bid like a pitch. Government evaluators score against stated criteria, not enthusiasm. Answer the criteria, in their order, in their language.
- Missing a mandatory requirement. One missed "must" and you are non-compliant before your quality is ever judged. Build a compliance checklist from the solicitation itself.
- Registering with codes too narrow (or too broad). Your commodity codes are your matching engine — tune them.
- Waiting for the perfect large contract. Small first wins build past performance, which is often itself an evaluation criterion. Start small on purpose.
- Ignoring standing offers and supply arrangements. Getting on these is where repeat, lower-competition work lives.
What's changed in 2026
Federal procurement has moved more in the past year than in the decade before it. A few of these shifts change exactly how you register and where the advantage now sits.
The supplier front door changed. The old Supplier Registration Information (SRI) system was retired in mid-2026. Suppliers now register on SAP Business Network (Ariba) through the CanadaBuys portal — if a guide still tells you to "register in SRI," it is out of date.
OSME has a new name. The Office of Small and Medium Enterprises is now Procurement Assistance Canada. Same free seminars, webinars, and one-on-one coaching from six regional offices — just a new name to search for.
Being Canadian became a scoring advantage. Under the Policy on Prioritizing Canadian Suppliers and Canadian Content, effective December 2025 and broadened in June 2026, genuine Canadian suppliers earn an evaluation credit — a roughly 10% weighting advantage — on larger strategic-sector procurements. It works through the scoring, not by excluding foreign bidders.
A dedicated SMB on-ramp is arriving. Budget 2025 funded a new Small and Medium Business Procurement Program ($79.9 million over five years) that reserves streams of contracts for Canadian SMBs and launches in 2026 — one more reason to register and set your commodity codes now, so you are notified as those set-asides open.
