How to register as a supplier on CanadaBuys: a step-by-step guide

CanadaBuys is the federal government's main online marketplace for buying goods and services. If you want to sell to federal departments, you almost always need an account there first. The registration itself is free, but it asks for details many small business owners don't have ready to go — so a bit of prep saves you a lot of stop-start frustration.

What CanadaBuys actually is

CanadaBuys is the Government of Canada's central procurement website. It replaced the old Buyandsell.gc.ca portal and now hosts almost every open federal tender (a public request for businesses to bid on a contract). Departments post their needs there, businesses respond, and buyers use the same system to manage the process from posting to award.

Having an account does two things. First, it lets you view and respond to tender notices that require registration. Second, it puts your business into the pool that buyers can search when they're looking for suppliers for smaller, lower-risk purchases that never get formally posted. If you're not registered, you're invisible for both.

Registering is not the same as pre-qualifying. It doesn't guarantee you'll win anything, and it doesn't replace the standing offers or supply arrangements some departments require for certain categories of work. Think of it as the front door — you still have to walk through the rest of the building yourself. For a broader sense of what's on the other side of that door, browse live tender search once your account is set up.

What you need before you start

Have these ready before you open the registration form. Stopping halfway through to go hunting for a document is the single biggest reason people abandon the process.

What you need	Why it's asked for	Where to find it
Legal business name and address	Must match your government registration exactly	Your incorporation or business licence documents
Business Number (BN)	Links your account to your CRA tax records	CRA business account or your incorporation paperwork
NAICS codes	Tells the system what industry you're in, so you're matched to relevant tenders	Look up your closest match at the registration stage
A working email you check often	All notices and updates arrive here	—
Banking details for payment	Needed if you're ever awarded a contract	A void cheque or direct deposit form
Basic company description	Buyers use this to understand what you offer	Write two or three plain sentences about your business

You don't need a lawyer or a consultant to do this. Most businesses can complete registration in under an hour once the documents above are on the desk.

Step-by-step: creating your account

1. Go to the CanadaBuys website and choose to register as a supplier rather than a buyer — the two paths look similar at first glance, so check you're on the right one.
2. Create your login credentials. You'll set up a username and password, and you may be asked to verify your email before continuing.
3. Enter your business identity details. This includes your legal name, any operating or trade name, your Business Number, and your mailing address. Small mismatches here (a missing suite number, an old address) can cause verification delays later, so copy these exactly from your official documents.
4. Select your NAICS codes. These are standard industry classification numbers used across North America. Pick every code that genuinely describes something you do — this is what determines which tender notices you get matched to. If you're unsure how these codes work, our plain-language explainer on NAICS and procurement codes walks through how to choose the right ones.
5. Build your Supplier Registration Information profile. This is often called your SRI profile — a structured record of your certifications, size, ownership status (including Indigenous or women-owned business status if applicable), and areas of expertise. It's more detailed than a basic sign-up form, and it's worth doing properly the first time. See our guide on what an SRI profile is and why you need one for a full breakdown.
6. Add banking information, so you're ready to be paid without a delay if you win a contract.
7. Review and submit. You'll typically get a confirmation email, and your account becomes active shortly after.

Getting your profile ready to actually win work

A completed registration is not the same as a strong profile. Buyers — and increasingly, automated matching tools — read your profile to decide whether to invite you to bid or shortlist you for smaller purchases. A thin, generic description gets skipped over.

Spend extra time on:

• Your company description. Say plainly what you do, who you've done it for, and what makes you a safe choice. Avoid vague marketing language; buyers are scanning for specifics.
• Every relevant NAICS code, not just your primary one. Many businesses lose out on smaller opportunities simply because they only listed one code.
• Certifications and set-aside status. If your business qualifies for Indigenous procurement programs or other set-asides, make sure that's reflected accurately — it can open doors to opportunities reserved for qualifying suppliers.
• A capability statement you can attach or reference. This is a short document summarizing your experience, past work, and qualifications in a format buyers expect. If you don't have one yet, our guide on how to build a capability statement that wins government contracts is a good next stop.

What's changing through 2026

Canadian procurement rules are shifting, and some of it affects registration directly. A federal Buy Canadian Policy began rolling out in December 2025, giving Canadian suppliers an evaluation advantage on certain federal contracts — currently focused on large strategic-sector purchases, with the threshold expected to widen through 2026. Large projects are also seeing new Canadian-content expectations for materials like steel, aluminum and wood.

More directly relevant to a first-time registrant is the Small Business Procurement Program, which is being introduced through 2026. It aims to make it easier for smaller suppliers to compete, including simpler, proportional requirements sized to smaller contracts and plain-language summaries of what a tender is actually asking for. Alongside it, a shared "Tell Us Once" attestation system is being built so you won't need to re-submit the same standard declarations — about your legal status, insurance, or eligibility — on every single bid. Once it's live, your CanadaBuys registration becomes even more valuable, since it's the record that system will draw from. We cover this in more detail in how to use the "Tell Us Once" attestation system to bid faster.

There's also a broader push to open up reciprocal procurement rules and reduce interprovincial trade barriers, which matters if you're weighing whether to focus on federal work, provincial work, or both. None of this changes how you register today, but it's worth registering with an accurate, complete profile now so you're positioned when these programs take effect.

Common mistakes that slow you down

• Using a business name that doesn't match your legal registration. This is the most common cause of verification delays.
• Picking only one NAICS code. It narrows what you get matched to far more than people expect.
• Leaving the company description blank or generic. "We provide quality services" tells a buyer nothing.
• Forgetting to update the profile after registering. Businesses change — new certifications, new services, a new address — and a stale profile stops reflecting reality.
• Registering and then never checking back. An account alone doesn't win contracts. Pair it with a regular habit of checking live tender listings for notices that match your NAICS codes.

After you're registered

Once your account is active, registration becomes a maintenance task rather than a one-time job. Revisit your profile every few months, especially after you add a new service line, win a new certification, or complete a notable project worth mentioning. It's also worth getting familiar with how individual departments operate and what they tend to buy, before you commit time to a bid.

Registering on CanadaBuys is a small, mechanical step compared to what comes next: finding the right opportunities, reading them properly, and putting together a bid that actually wins. But it's the step everything else depends on, and it's one you only need to get right once. Treat it as the start of a habit, not a box to tick, and the rest of the process gets easier from here.
