What is CanadaBuys, exactly?
CanadaBuys is a website. When a federal department needs to buy something, whether that's IT services, office furniture, a road resurfacing job, or translation work, they post a tender notice on canadabuys.canada.ca. Any qualifying supplier can read it, ask questions during the official Q&A period, and submit a bid by the closing date.
The platform combines three functions that used to live in separate systems:
- Publication. Every federal tender notice and award notice is posted here.
- Sourcing. Many (but not all) bids are submitted electronically through the platform.
- Supplier registration. Businesses register so federal buyers can find them, and so they can receive notifications when relevant tenders are published.
Registration affects more than eligibility. The product and service categories in your profile decide which opportunity notifications reach you, and an incomplete Government of Canada questionnaire blocks you from submitting a bid at all.
Who runs CanadaBuys, and why does it exist?
CanadaBuys is operated by Public Services and Procurement Canada (PSPC), the federal department that manages roughly $20 billion in annual purchasing on behalf of the rest of government. PSPC is, in practical terms, the federal government's central buyer. For the full end-to-end picture (procurement methods, instruments, trade agreement thresholds, evaluation, and CITT/OPO recourse), see our pillar guide on the Canadian government procurement process.
The portal exists for two reasons. First, Canada's trade obligations under agreements like the Canadian Free Trade Agreement (CFTA), CUSMA, CETA, and the WTO Government Procurement Agreement require that federal procurements above certain thresholds be advertised openly. CanadaBuys is the Government Electronic Tendering Service (GETS), which is the official channel Canada uses to meet that obligation. Second, the federal government wanted a single modern system to replace the patchwork of legacy platforms (Buyandsell.gc.ca, the old MERX-hosted federal feed, and various siloed tools) that suppliers had to juggle.
So CanadaBuys is not a marketplace in the Amazon sense. It's a regulated tendering system that Canada is legally obligated to operate.
What can you actually do on CanadaBuys?
Four things, primarily.
You can search open tender opportunities across all federal departments and agencies, plus a growing number of broader public sector entities (provinces, municipalities, hospitals, and academic institutions that opt in). You can set up saved searches and email alerts so new tenders matching your keywords arrive in your inbox. You can find the links to register your business in SAP Business Network. And you can submit bids electronically for tenders that are run through the platform's e-bidding system, though not every tender uses it.
You can also download awarded contract data, request a contract history letter if you've sold to the government before, and find the UNSPSC commodity codes that classify what you sell. UNSPSC replaced the older GSIN system in recent years, and is what notices, supplier profiles, and search filters use to classify work.
Do you have to register on CanadaBuys to bid?
Yes, in almost every practical case.
Searching tenders and reading documents is free and requires no account. The moment you want to submit a bid or receive notifications, you need to register. The registration process changed in 2026, and older advice is still circulating, so this is where most first-time bidders get tangled up.
SRI is retired: registration now runs through SAP Business Network
For years, federal registration meant two parallel systems: the Supplier Registration Information (SRI) directory, which issued a Procurement Business Number (PBN), and SAP Ariba for tenders that had moved onto the new e-procurement platform. Earlier versions of this guide told you to register in both. That advice is now out of date.
The practical answer for an SMB starting today is one registration, not two. Create your SAP Business Network account, then complete the Government of Canada questionnaire before your first bid. The full step-by-step, including what to do if a notice still asks for a PBN, is in how to register to bid on CanadaBuys.
There's a third channel worth knowing about. Some tenders still require physical bid submission through Canada Post Connect or a designated bid receiving unit. These are the minority, but they exist, and missing the submission method is one of the more painful disqualifications a contractor can earn.

How CanadaBuys fits with MERX, BC Bid, and provincial portals
A common point of confusion: CanadaBuys is federal only. Despite the broad name, it does not cover provincial, territorial, or most municipal procurement.
If you're an SMB contractor in Canada, the public-sector landscape you actually have to monitor looks something like this:
- CanadaBuys for federal departments, agencies, most Crown corporations, and broader public sector opt-ins
- MERX, a private commercial portal that aggregates federal, provincial, and municipal opportunities. It was once the federal default, but is now a third-party tool
- BC Bid, SaskTenders, Alberta Purchasing Connection, the Ontario Tenders Portal, and equivalents in other provinces, each running on its own system
- bids&tenders, Bonfire, Biddingo, which are software platforms that many municipalities use to host their tenders
At a glance, here's how the four categories compare:
If you're trying to figure out which one matters for your business, three guides in this series cover it directly: MERX vs CanadaBuys, BC Bid vs CanadaBuys, and Ontario Tenders Portal vs CanadaBuys.
What changed under the Buy Canadian Policy?
Many CanadaBuys explainers still predate these rules. As of December 16, 2025, federal procurement operates under the new Buy Canadian Procurement Policy Framework, and the rules that affect SMBs are still rolling out through 2026.
The pieces that matter most for a contractor reading a CanadaBuys tender notice today:
A 10% bid-price discount applies to Canadian suppliers on procurements covered by the Policy on Prioritizing Canadian Suppliers and Canadian Content in Strategic Federal Procurements. For evaluation purposes, your price is treated as 10% lower than what you actually bid, which is a meaningful advantage in close competitions.
A 25% Canadian-content evaluation weighting applies to those same covered procurements, either as a scored criterion or a credit. The more Canadian value-added your bid commits to, the better you score.
The covered-procurement threshold dropped on June 15, 2026. The policy launched at $25 million and up; it now applies at $5 million and up in covered sectors (defence and security, health and pharmaceutical, infrastructure and construction and transportation, ICT, and consumer and industrial goods). PSPC estimates that puts roughly five times more federal procurements under Canadian preference measures, including ones SMBs realistically bid on as primes or subs. The separate Policy on Prioritizing Canadian Materials (steel, aluminum, and wood in construction and defence) stays at $25 million.
The Interim Policy on Reciprocal Procurement, in effect since July 14, 2025, restricts most federal procurements above $10,000 to suppliers from Canada or from countries that give Canadian suppliers reciprocal market access through trade agreements. Ottawa signalled a permanent version for 2026, but as of September 2026 the interim policy is still the one in force. Existing standing offers and supply arrangements were brought under it at renewal by July 14, 2026.
PSPC launched the Small Business Procurement Program on July 6, 2026. It defines a small business as one with 499 or fewer employees, including affiliates. The first phase (summer 2026) requires federal buyers to design procurements proportionally with small businesses in mind, expands standardized procurement documents, and upgrades Procura, the CanadaBuys AI assistant. The second phase, promised by the end of 2026, adds plain-language tender summaries, a "Tell Us Once" approach so you submit common documents once, structured response formats, pre-submission completeness checks, and a recognition program for trusted Canadian small suppliers.
If you're a Canadian-based SMB, the net effect is that the federal market in 2026 is structurally more favourable to you than it was 18 months ago. The flip side is that "Canadian supplier" now has a specific legal definition. It means a place of business in Canada operating on a permanent basis, registered and tax-filing in Canada, with personnel or day-to-day activities here. You'll need to be able to demonstrate it.
What does this mean for your bid strategy?
Three practical takeaways for an SMB starting from zero.
First, treat CanadaBuys as the source of truth, not your only intel channel. The portal is where the official notice lives, but tender amendments, Q&A responses, and submission rules all need active monitoring. Saved searches with email alerts are a starting point, not the whole solution.
Second, register in SAP Business Network now, even if you're not bidding yet. Setting up the account and completing the Government of Canada questionnaire takes an evening, and doing it the week a tender closes is how bids get missed. The registration is free.
Third, read the tender notice top to bottom before you commit any bid effort. The notice tells you which submission system to use, what mandatory criteria apply, whether the procurement is covered by Buy Canadian rules, and which trade agreements govern it. The single most common reason SMBs lose federal tenders is missing or misreading information that was in the notice the whole time.
