Five essential facts about the Ontario Business Registry search, based on official government sources.

How to check someone’s business registration in Ontario?

The official starting point is the Ontario Business Registry (OBR) portal operated by ServiceOntario. You don’t need an account to search — just a browser.

Using the Ontario Business Registry website

1. Go to ontario.ca/page/ontario-business-registry (Ontario.ca – Government of Ontario)
2. Click “Search for a business” from the main menu
3. Choose search by business name or Ontario Corporation Number (OCN)

Entering the business name or registration number

For a name search, enter the full or partial legal name. The system returns matching records. If you have the 7- or 9-digit OCN, searching by number gives an exact match (Pacific Legal – Ontario Corporate Search Guide).

Interpreting the search results

• Active status means the business is legally registered and in good standing (Pacific Legal – Ontario Corporate Search Guide)
• Dissolved or Inactive means the entity is no longer valid
• Basic results show the business name, status, incorporation date, and registered office address

The implication: A simple free search lets you confirm whether a company actually exists as a legal entity in Ontario — the first step in any due diligence check.

How to check if a business is legit in Ontario?

Registration in the OBR means a business has satisfied legal requirements to operate in Ontario. But “legitimate” goes beyond a simple status check.

Cross-referencing with the Ontario Business Registry

• Confirm the business name and registration number match official records
• Verify the status is “Active” and not “Suspended” or “Dissolved” (Pacific Legal – Ontario Corporate Search Guide)
• Check the registered office address matches where the business claims to operate

Understanding the limits of registry data

An active registration does not guarantee financial solvency, ethical practices, or customer satisfaction. The OBR is a legal registry, not a consumer review platform. Always combine registry results with other verification methods like checking for complaints or requesting references.

The trade-off: The OBR gives you legal certainty but not commercial certainty. Use it as a starting point, not a final verdict.

How to search business names in Ontario?

If you’re starting a new business, checking name availability is crucial before incorporation.

Conducting a name search on the OBR

• Use the free name search on the OBR website to see if any existing business has a similar name
• For incorporated businesses, a NUANS search is required to check against existing corporate names and trademarks (Ownr Platform Tutorial)

Using the NUANS search for corporate names

The NUANS (Newly Updated Automated Name Search) system compares your proposed name against a database of existing corporations and trademark registrations. This is a mandatory step for incorporating a business in Ontario.

Reserving a name

Once you find an available name, you can reserve it for up to 90 days by filing a name reservation request through the OBR. A fee applies.

Why this matters: Even if a name is available provincially, it may conflict with a federal trademark. A simple OBR search can’t catch that — a full NUANS search is your safety net.

How do I find the owner of a company in Ontario?

Finding ownership information depends on the business structure.

Accessing corporate profile reports

For corporations, purchase a detailed corporate profile report ($8) through the OBR. This report lists directors, their addresses, and sometimes officers (Ontario.ca – Official Government of Ontario).

Identifying directors and officers

The profile report shows the names and addresses of current directors. For a sole proprietorship or partnership, this information is not publicly listed in the OBR.

Understanding privacy limitations

The OBR does not disclose shareholders or beneficial owners. Only directors’ names appear on public records. If you need deeper ownership details, you may need to request documents such as annual filings.

How to check if a business name is registered in Canada?

Business names can be registered provincially or federally. Here’s how to check across jurisdictions.

Using the Canadian Business Registry (MRAS)

• The Business Registry Search (formerly MRAS) allows you to search multiple provincial registries at once
• It covers participating provinces and territories, including Ontario

Searching provincial registries individually

Each province has its own registry. For Ontario, the OBR is the primary source. If a business is federally incorporated, search the Corporations Canada database (ISED – Innovation, Science and Economic Development Canada).

Understanding federal vs provincial registration

A federally incorporated business has a different registration number and must be searched on the federal registry. A name may be available in Ontario but taken federally (OpenCompany – Business Registration Guide).

The pattern: A name might be available in Ontario but already registered federally or in another province. Always search both the provincial and federal registries before finalizing your business name.

“The Ontario Business Registry enables public access to business information, supporting transparency and due diligence for consumers and businesses alike.”

— Ontario Ministry of Public and Business Service Delivery

“When verifying a business, always start with the official provincial registry. It’s the only place you’ll find legally confirmed data.”

— Canadian Consumer Verification

For anyone dealing with a new business relationship — whether as a customer, partner, or investor — the Ontario Business Registry is the first and most reliable verification tool. It won’t tell you if a business is trustworthy, but it will tell you if it’s legally real. For Ontario consumers, the choice is clear: use the free OBR search to confirm registration before committing money or signing a contract, or risk dealing with an entity that may not even exist on paper.
