How to bid on Canadian government contracts

The federal government spends over $25 billion a year on goods, services, and construction. Provinces and cities add billions more. This guide covers how the process works — and how Sidona helps you find, read, and pursue the right opportunities.

What is CanadaBuys?

CanadaBuys is the Government of Canada's official electronic procurement platform. Launched in 2023 to replace the legacy MERX system and Buyandsell.gc.ca, it is the single window for federal procurement opportunities.

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

The platform is free to access, but it can be difficult to navigate, offers limited alerting, and does not always present information in a business-friendly format. Provincial and municipal portals add another layer of fragmentation—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. The process is governed by the Government Contracts Regulations, Treasury Board policies, and Canada's obligations under trade agreements such as CFTA, CPTPP, and CUSMA.

The procurement lifecycle

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
Solicitation
The opportunity is published on CanadaBuys or a provincial portal. The package includes scope, evaluation criteria, mandatory requirements, and submission instructions.
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
Evaluation
Proposals are scored against published criteria—technical merit, price, or best value. The process is standardized and auditable.
5
Award
A contract is issued to the selected supplier. Award notices are published for transparency.
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

Government tenders are categorized into procurement categories. Understanding your category—and your GSIN or UNSPSC 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.

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

Get a Business Number

Obtain a Business Number (BN) from the Canada Revenue Agency. This is your unique identifier for all interactions with the federal government.

Step 2

Register on CanadaBuys

Create a supplier account with your business details, areas of expertise, and GSIN/UNSPSC codes for the goods and services you offer.

Step 3

Get security clearances (if required)

Defence, IT, and construction contracts often require personnel clearances through the Contract Security Program. Plan for two to six months.

Step 4

Pre-qualify where possible

Some vehicles require pre-qualification—such as PSPC Supply Arrangements. 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, GSIN 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 RFQs
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 a tender PDF and Sidona has finished processing it.

When Talk to the Tender is available

No RFQ 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 geographic or Canadian-content requirements?

Tips for Writing Winning Bids

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

Read the entire solicitation

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

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.

Mirror the RFP structure

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

Demonstrate past performance

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

Price competitively, not cheaply

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

Submit on time

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

Success rate

Do not be discouraged if you do not win your first bids. Many seasoned government contractors report a 15–25% win rate. Each bid teaches you something about the process.

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 two to six weeks.
Forgetting security clearance lead times, which can take months through the Contract Security Program.
Skipping debriefs after a loss—you have the right to learn where you scored well and where you fell short.

The “Buy Canadian” Policy and What It Means for SMEs

The Canadian government has strengthened support for domestic businesses through procurement. The evolving Buy Canadian framework is designed to give Canadian companies—particularly small and medium-sized enterprises (SMEs)—a competitive advantage in federal procurement.

What this means in practice

Set-asides for Canadian businesses: Certain procurements below trade agreement thresholds are restricted to Canadian suppliers.
SME procurement targets: The government has committed to awarding a percentage of contracts to small businesses, Indigenous businesses, and social enterprises.
Simplified procurement: Lower-value contracts use processes more accessible to smaller firms.
Regional considerations: Some procurements include regional economic benefit requirements favouring local suppliers.

Trade agreement thresholds (2026)

Below these thresholds, the government has more flexibility to prioritize Canadian suppliers—where SMEs often have the biggest opportunity:

Goods
~$30,300 (CFTA) to ~$100,000+ (international)
Services
~$105,700 (CFTA) to ~$130,000+ (international)
Construction
~$264,400 (CFTA) to ~$13M+ (international)

Indigenous procurement

The Procurement Strategy for Indigenous Business (PSIB) sets aside specific contracts for Indigenous-owned businesses. If you qualify, this is a significant competitive advantage.
