Ontario Business Name Registration at a Glance

What Is a Trade Name in Ontario?

A trade name, sometimes called an operating name or “doing business as” (DBA) name, is a name a business uses publicly that differs from its legal name.

For example:

• A sole proprietor named Maria Chen operating as Chen Design Studio is using a business name rather than only her legal name.
• A corporation legally named 1234567 Ontario Inc. operating as Northside Coffee Co. is using a business or trade name.
• A general partnership operating as Lakeview Contracting is using a registered firm name.

The underlying legal person or entity does not disappear when a trade name is registered. A sole proprietor remains the individual operating the business, while a corporation continues to exist under its legal corporate name.

The registered business name is the name the business can use publicly for activities such as marketing, signage, contracts, and banking, subject to applicable legal requirements.

Ontario’s Business Names Act covers several related registrations:

The Ontario Business Registry handles these registrations.

Do You Need to Register a Trade Name in Ontario?

Ontario’s Business Names Act generally requires a business name to be registered when a person or corporation carries on business under a name that differs from the applicable legal name.

You generally need to register if:

• You’re a sole proprietor operating under a business name rather than your own name
• You’re operating a general partnership under a firm name
• Your corporation operates a store, division, service or brand under a name different from its registered corporate name

For example, if 1234567 Ontario Inc. wants to operate publicly as Northside Coffee Co., the corporation would generally register Northside Coffee Co. as its business name.

You may not need a separate business name registration if:

• You’re an individual carrying on business strictly under your own legal name
• Your corporation operates only under its exact registered corporate name

Ontario’s Business Names Act sets out the statutory requirements for when corporations, individuals, and partnerships must register the names under which they carry on business.

For the current government requirements, see the Ontario Business Registry.

Trade Name vs. Business Name vs. Master Business Licence

These terms are often used interchangeably, but they have important distinctions.

Business Name Registration

Business Name Registration is Ontario’s current terminology for registering business names under the province’s registry system.

It includes registrations for sole proprietorships, partnerships, and business names used by corporations.

Master Business Licence

Master Business Licence, often shortened to MBL, is the older term that many Ontario business owners, banks, and service providers still use.

Ontario now refers to the document and process as a Business Name Registration, but searches for “Master Business Licence Ontario” are still common.

Trade Name

A trade name or operating name generally refers to a name an existing business or corporation uses publicly that differs from its legal name.

For example:

• Legal corporate name: 1234567 Ontario Inc.
• Trade name: Northside Coffee Co.

The corporation remains 1234567 Ontario Inc. legally, but it can conduct business under its registered trade name.

Incorporation

Incorporation is different.

Incorporating creates a separate legal corporation. Registering a trade or business name does not.

Ontario’s current online government fee to incorporate a business corporation is $300, compared with $60 for many Business Names Act registrations.

If you’re deciding whether you need a simple business registration or a corporation, compare the legal, liability, tax, and compliance differences before choosing based on filing cost alone.

How to Register a Trade Name in Ontario

You complete trade name and business name registrations through the Ontario Business Registry (OBR), the province’s official online system for business registrations and corporate filings.

Step 1: Search Your Proposed Business Name

Before registering, search the Ontario Business Registry to see whether the proposed business name is already being used.

A preliminary search can help you spot obvious conflicts before you spend money on branding, signage, a domain, or marketing materials.

However, registering a business name does not guarantee exclusive rights to that name or confirm that it is free of trademark or other legal conflicts.

For a more extensive name search, you may also consider a Nuans® report. See our guide to Nuans® searches and name requirements for more information about when a broader name search can be useful.

Step 2: Create Your Ontario Registry Access

To use the Ontario Business Registry online, you may need:

• An Ontario.ca login
• An Ontario Business Account
• Your company key when linking an existing business or corporation

If you’re creating a new registration, the system will guide you through the required account setup.

If you’re trying to access an existing entity in the registry, you may need its company key to link that business to your Ontario Business Account.

Step 3: Gather Your Registration Information

The information you need depends on the type of registration, but you should generally have:

• The exact business or trade name you want to register
• Business address information
• A description of the business activity
• Owner or partner information, where applicable
• Corporate information if an existing corporation is registering a business name

Make sure the information is accurate before submitting the registration.

Step 4: Complete the Registration Online

Enter the required information through the Ontario Business Registry and review it carefully before submission.

For online Business Names Act registrations, Ontario currently lists immediate service for standard registrations.

Step 5: Pay the Registration Fee

The Ontario government fee for online registration is currently $60 for:

• Sole proprietorships
• General partnerships
• Business names registered by corporations

Other entity types can have different fees.

Step 6: Save Your Registration Documents

After registration, keep your Business Name Registration documents with your business records.

You will also receive or use an Ontario Business Identification Number (BIN) associated with the registration.

Do not confuse the Ontario BIN with the federal Business Number (BN) issued by the Canada Revenue Agency. They are different identifiers used for different purposes.

How Much Does Trade Name Registration Cost in Ontario?

For many common Ontario business name registrations, the government fee is $60 when filed online.

Ontario currently lists standard online Business Names Act registrations as immediate.

If you file through a third-party registration service, the service provider may charge an additional fee to prepare, review, and submit the filing.

Ontario Business Name Rules and Restrictions

Registering a business name does not mean the Ontario government has given you exclusive ownership of that name.

The Registrar can refuse a name that does not comply with the Business Names Act or other requirements, and Ontario restricts certain words, expressions, and types of names.

More importantly, registration does not eliminate the possibility of a conflict with another business name, corporate name, or trademark.

Ontario’s Business Names Act provides legal remedies in certain circumstances involving the use or registration of the same or deceptively similar names.

That is why a name search should be treated as part of your due diligence rather than as a guarantee that the name is legally available.

Before investing significantly in a brand, consider checking:

• Ontario business registrations
• Corporate names
• Nuans® search results where appropriate
• Canadian trademarks
• Domain names
• Existing businesses using similar names

The more important the brand is to the long-term business, the more important this research becomes.

Does Registering a Trade Name Give You Trademark Protection?

No.

Registering a business or trade name in Ontario and registering a trademark are two different legal processes.

A Business Name Registration allows you to register the name under which you carry on business in Ontario. It does not automatically give you exclusive rights to that name across Canada.

Trademark registration is handled federally through the Canadian Intellectual Property Office and covers trademark rights.

This distinction matters if you are building a brand that you expect to use long-term, expand outside Ontario, licence to others, or invest heavily in promoting.

A business can therefore have both:

• Business Name Registration: establishes the name under which it carries on business.
• Trademark Registration: provides broader legal protection for a qualifying brand, name, logo, or other trademark.

How Long Is a Trade Name Registration Valid in Ontario?

An Ontario Business Name Registration is valid for five years.

Ontario allows you to renew a business name registration starting six months before its expiry date and up to 60 days after it expires.

How to Renew an Ontario Business Name

To renew through the Ontario Business Registry:

1. Sign in using your Ontario.ca Login.
2. Select the applicable business name.
3. Choose the renewal option under “Make changes.”
4. Review the registration information.
5. Pay the applicable renewal fee.

For a sole proprietorship, general partnership, and many business-name registrations, the renewal fee is currently $60.

What If the Registration Has Been Expired for More Than 60 Days?

If the Business Name Registration has expired for more than 60 days, Ontario does not allow it to be renewed.

Instead, you need to complete a new Business Name Registration.

Ontario states that the new registration will result in a new Business Identification Number (BIN) and a new company key.

Because of this, it is worth tracking the five-year expiry date rather than waiting until after the registration has expired.

If other business information changes before renewal, see MD Legals’ Update Your Business Online service for information about updating existing business records.

What a Trade Name Registration Does Not Do

A trade name registration serves an important compliance purpose, but it has limits.

It Does Not Incorporate Your Business

Registering a sole proprietorship or trade name does not create a separate corporation.

If you operate as a sole proprietor, you remain personally responsible for the business subject to applicable law.

It Does Not Automatically Give You Exclusive Rights to the Name

Business name registration should not be confused with trademark protection.

Another business name or trademark issue may still arise, even if your registration is accepted.

It Does Not Replace Tax Registrations

An Ontario Business Identification Number is different from the CRA Business Number used for federal tax programs.

Depending on the business, you may also need separate CRA accounts for GST/HST, payroll, corporate income tax, or other programs.

It Does Not Eliminate Ongoing Filing Requirements

If information associated with your registration changes, you may need to update the Ontario Business Registry.

You must also renew your business name registration every five years to keep it active.

Common Trade Name Registration Mistakes

• Assuming registration gives you exclusive ownership of the name. It doesn’t. Registering the business name and protecting a brand through trademark law are separate issues.
• Skipping the name search. Finding a conflicting business or trademark after investing in a website, signage, and marketing can be far more expensive than researching the proposed name beforehand.
• Confusing your BIN with your CRA Business Number. The Ontario Business Identification Number and the CRA Business Number are different identifiers. Keep records of both if your business has them.
• Forgetting the five-year renewal. Business Name Registrations expire after five years. Ontario provides a renewal window that begins six months before expiry and extends up to 60 days afterward.
• Waiting more than 60 days after expiry. Once the registration has expired for more than 60 days, it can no longer be renewed. A new registration is required.
