How to bid on Canadian government contracts (2026)

In 2024–25 the Government of Canada awarded $66.9 billion in contracts for goods, services, and construction—and provinces, cities, schools, and hospitals buy on top of that. This guide covers how Canadian government procurement works, and how AI procurement software like Sidona helps you find, read, and pursue the right tenders.

What is CanadaBuys?

CanadaBuys is the Government of Canada's official source for federal tender and award notices. It took over from Buyandsell.gc.ca in 2022 (Buyandsell was fully decommissioned in 2025), and federal bidding runs through the SAP Ariba tools behind it.

Federal departments publish Requests for Proposals (RFPs), Requests for Quotations (RFQs), Advance Contract Award Notices (ACANs), and other instruments on CanadaBuys. Notice data is published as open data under the Open Government Licence — Canada.

The platform is free to use, but it covers only part of the market. Provinces, cities, schools, and hospitals publish on their own portals—which is why tools like Sidona aggregate multiple sources into one searchable workspace.

How Government Procurement Works in Canada

Canadian federal procurement follows strict rules designed to ensure fairness, transparency, and value for taxpayers. It is governed by the Government Contracts Regulations, Treasury Board's Directive on the Management of Procurement, and trade agreements: the Canadian Free Trade Agreement (CFTA) at home, and internationally the WTO Agreement on Government Procurement, CETA, CPTPP, and other free trade agreements. (CUSMA's procurement chapter does not apply to Canada.)

The procurement lifecycle

  1. 1

    Planning

    A department identifies a need and develops requirements. Large procurements may start with RFIs or Letters of Interest to consult industry before a formal solicitation.

  2. 2

    Solicitation

    The opportunity is published on CanadaBuys or a provincial portal. The package includes scope, evaluation criteria, mandatory requirements, and submission instructions.

  3. 3

    Bidding period

    Suppliers prepare proposals before the closing date. Questions submitted during this window are answered via published amendments visible to all bidders.

  4. 4

    Evaluation

    Proposals are scored against published criteria—technical merit, price, or best value. The process is standardized and auditable.

  5. 5

    Award

    A contract is issued to the selected supplier. Award notices are published for transparency.

  6. 6

    Contract management

    Work is delivered, accepted, and paid according to contract terms. Amendments and change orders follow the same public rules.

Key procurement methods

  • Open bidding: Available to all qualified suppliers—the default above certain thresholds.
  • Selective / limited tendering: Only pre-qualified suppliers are invited. Used when specific qualifications are required.
  • Standing offers & supply arrangements: Pre-established agreements the government can call up as needed—like a pre-approved vendor list.
  • Advance Contract Award Notice (ACAN): The government signals intent to award to a specific supplier and gives others a chance to challenge the decision.

Types of Tenders

CanadaBuys sorts tenders into procurement categories. Understanding your category—and your UNSPSC (or older GSIN) codes—helps you find opportunities that match your business.

CNST

Construction

Building, renovation, repair, and maintenance of structures—roads, bridges, buildings, and marine works. Often requires bonding and security clearances.

GD

Goods

Physical products from office supplies and IT equipment to vehicles and scientific instruments. Trade agreement thresholds apply.

SRV

Services

Professional, consulting, and support services—IT, translation, training, janitorial, and more. The largest category by volume.

SRVTGD

Services tied to goods

Services bundled with a goods component, such as IT implementation with hardware or maintenance contracts that include parts.

How to Register as a Government Supplier

Before you can bid on federal contracts, you need to get set up:

Step 1

Register in SAP Business Network

Create a Standard account and complete the Government of Canada supplier questionnaire. Since July 2026 this is how federal suppliers register—the old Supplier Registration Information (SRI) system is retired. Then use CanadaBuys to find and bid on opportunities.

Step 2

Have a CRA business number

You need a Canada Revenue Agency business number before a contract can be awarded—not to submit a bid. Businesses outside Canada can register for a non-resident one.

Step 3

Get security clearances (if required)

Defence, IT, and construction contracts often require organization and personnel clearances through the Contract Security Program. Clearances can take months, so start before you need them.

Step 4

Pre-qualify where possible

Some work is only available through pre-qualified vehicles—such as PSPC supply arrangements and standing offers. Getting on these lists means call-ups without competing from scratch each time.

Pro tip

Registration is free. Do not pay third parties that promise to “register you as a government supplier”—the process is straightforward and you can do it yourself.

How to Find Relevant Tenders

Finding the right opportunities is half the battle. Here are the main approaches:

Option 1: Browse portals directly

Search CanadaBuys and provincial sites by keyword, commodity code, category, and contracting entity. The interfaces are functional but fragmented—you check each portal manually and there is limited smart alerting.

Option 2: Use Sidona

Sidona pulls federal and provincial opportunities into one feed, syncs on a schedule, and gives you better search, filters, and a saved watchlist. From the dashboard you can:

  • Keyword or AI semantic search across all sources
  • Filter by level, province, closing date, and chat-ready documents
  • See new tenders and ones closing in the next 14 days on Home
  • Save opportunities to a shortlist and revisit from Saved

Option 3: Network and industry events

Attend procurement conferences and industry days. PSPC and other departments often discuss upcoming requirements before formal solicitations are published—giving you a head start on bid preparation.

Read RFQs Faster with Sidona

Government solicitations can run hundreds of pages. Sidona's Talk to the Tender feature lets you ask questions directly against the official RFQ—but only when the source portal provides the document as a PDF and Sidona has finished processing it.

When Talk to the Tender is available

No PDF

Metadata and source link only—no chat.

PDF processing

Document detected; Sidona is ingesting and embedding it.

Chat ready

Ask about requirements, deadlines, and eligibility with page citations.

On the Contracts page, enable the Chat Ready filter to show only tenders where document Q&A is live. Look for the Chat badge on contract cards.

Example questions to ask

  • What are the mandatory security or certification requirements?
  • When is the submission deadline and what format is required?
  • What evaluation criteria carry the most weight?
  • Are there Canadian-content or Buy Canadian requirements?

Tips for Writing Winning Bids

Government bids are won on substance, not style. The fundamentals:

  1. 1

    Read the entire solicitation

    Government RFPs are long for a reason. Every requirement, clause, and evaluation criterion matters—including annexes and referenced standards.

  2. 2

    Answer exactly what is asked

    Evaluators score against a checklist. If the RFP asks for three references from the last five years, provide exactly that—not two, not older projects.

  3. 3

    Mirror the RFP structure

    Use the same section numbers and headings as the solicitation. A well-organized response signals professionalism and makes scoring easier.

  4. 4

    Demonstrate past performance

    Government buyers are risk-averse. Show similar work with measurable outcomes—dates, dollar values, and client names where permitted.

  5. 5

    Price competitively, not cheaply

    Lowest price does not always win. Many procurements use best-value scoring where technical merit carries significant weight.

  6. 6

    Submit on time

    Late bids are rejected without exception. Submit at least 24 hours before the deadline to account for portal or upload issues.

Keep going

Do not be discouraged if you do not win your first bids. Ask for a debrief after every loss—each one teaches you how evaluators score.

Common Mistakes to Avoid

  • Bidding on everything instead of opportunities where you have genuine expertise.
  • Ignoring mandatory requirements—missing ISO certification or clearances makes your bid non-compliant regardless of quality.
  • Copy-pasting from previous proposals instead of tailoring to the specific solicitation.
  • Not asking questions during the bidding period when requirements are unclear.
  • Underestimating preparation time—quality proposals often take weeks, not days.
  • Forgetting security clearance lead times, which can take months through the Contract Security Program.
  • Skipping debriefs after a loss—you can ask where you scored well and where you fell short.

The Buy Canadian Policy and What It Means for Suppliers

The Buy Canadian Policy took effect on December 16, 2025. It changes who can win federal work and what goes into it:

  • Canadian suppliers and content: Strategic procurements prioritize Canadian suppliers and reward Canadian content. It started with procurements of $25 million and up, and since June 15, 2026 covers those of $5 million and up.
  • Canadian materials: Major federal construction and defence projects must use Canadian-produced materials.
  • Reciprocal procurement: Since July 14, 2025, new non-defence federal procurements over $10,000 are open to foreign suppliers only when a trade agreement between Canada and their country covers the procurement. To count as Canadian, a supplier needs a permanent, identified place of business in Canada.
  • Small Business Procurement Program: Announced in July 2026, it asks federal buyers to keep requirements proportionate to the opportunity and expands standard solicitation and contract templates.

Trade agreement thresholds (2026–2027)

For federal departments and agencies, a procurement at or above these values is covered by the agreement—which also decides which foreign suppliers may compete. Below the CFTA values, departments have more flexibility in how they compete the work.

  • Goods — CFTA

    $34,700

  • Services & construction — CFTA

    $139,000

  • Goods & services — WTO-GPA, CETA, CPTPP

    $239,200

  • Construction — WTO-GPA, CETA, CPTPP

    $9,200,000

Source: Contracting Policy Notice 2025-8, in effect January 1, 2026 to December 31, 2027. Crown corporations have higher values.

Indigenous procurement

The Procurement Strategy for Indigenous Business (PSIB) sets aside contracts for Indigenous businesses listed in the Indigenous Business Directory, and federal departments have a target of at least 5% of contract value going to Indigenous businesses. If you qualify, this is a significant competitive advantage.
