How small businesses can sell to governments across Canada

Many small businesses think government contracts are out of reach. In fact, governments in Canada buy billions of dollars in goods and services each year. A large share is open to small and medium-sized enterprises (SMEs). The starting point for federal contracts is CanadaBuys, the Government of Canada’s official procurement platform.

This guide explains how your business can sell to governments across Canada. It focuses on registering as a supplier, finding opportunities, and avoiding common mistakes.

How government buying works in Canada

Government procurement is decentralized. There is no single portal for every contract in the country.

Here’s how it works:

Federal government: Uses CanadaBuys to publish tenders and manage supplier registration.
Provincial and territorial governments: Each runs its own tendering system.
Municipal governments and agencies: Often use regional or third-party portals.

For most small businesses, federal procurement is a good entry point. Registration is free and standardized across departments.

Registering as a supplier with CanadaBuys

To sell to the federal government, you must register on CanadaBuys — Register as a supplier.

CanadaBuys lets you:

Register your business as a federal supplier.
Receive a Procurement Business Number (PBN).
Search and bid on active federal tenders.
Access standing offers and supply arrangements when eligible.

What you need to register

Registration is free. You will need:

Legal business name and operating name.
Business number (BN) if you have one.
Contact information for your business.
Basic details about the goods or services you sell.

Once registered, your PBN is used across federal departments. You only do this step once.

If you want to find grant programs that support your business growth, GrantHub’s eligibility matcher can help you filter options by province and industry.

Finding contract opportunities on CanadaBuys

After registering, you can search open opportunities directly on the CanadaBuys portal.

Common federal procurement types include:

Open tenders: Any qualified supplier can bid.
Standing offers: Pre-qualified supplier lists used for repeat purchases.
Supply arrangements: Multi-supplier frameworks for future contracts.

Most opportunities include:

A detailed statement of work.
Mandatory technical and financial criteria.
Clear submission deadlines and formats.

Missing even one mandatory requirement can disqualify your bid. Pay close attention to every detail.

Provincial and territorial tender portals

Besides CanadaBuys, many provinces and territories operate their own systems:

Ontario Tenders Portal – Central portal for Ontario public sector buyers.
New Brunswick Opportunities Network (NBON) – Tenders Online for New Brunswick.
Prince Edward Island Tenders – Provincial procurement opportunities.

Each system has its own supplier registration and rules. If your business sells nationally, expect to manage several vendor profiles.

Grants and programs that support selling to government

Selling to government is not the same as receiving a grant. However, some programs help businesses enter public-sector supply chains.

One example is the Business Scale-up and Productivity (BSP) program, delivered by PrairiesCan.

Based on program details:

BSP supports Prairie-based SMEs aiming to scale up, including those looking to enter government supply chains.
Funding may be repayable or non-repayable, assessed case by case.
Projects can include capability upgrades, certifications, or production capacity tied to procurement.

Programs like BSP often pair well with federal procurement, especially for manufacturing, technology, and dual-use products. If you want to find similar programs in your region, GrantHub lists hundreds of active grants across Canada.

Common mistakes to avoid

1. Registering but not setting up search alerts

Many businesses register on CanadaBuys and stop there. Without saved searches or alerts, you may miss relevant tenders.

2. Ignoring mandatory criteria

If a tender lists a requirement as “mandatory,” partial compliance is not enough. Missing one document can disqualify your bid.

3. Underestimating timelines

Government contracts move slowly. Plan your cash flow carefully, especially if you are a first-time supplier.

4. Bidding beyond your capacity

Winning a contract you cannot deliver can harm your supplier record. Start with smaller opportunities that match your current capacity.
