Master business license in Ontario, the current official term is Business Name Registration. It is commonly required when a sole proprietor, partnership, or corporation operates under a registered business name. Registration is completed through the Ontario Business Registry, generally costs $60 online, and is valid for five years.
What Is a Master Business License in Ontario?
A Master Business Licence is the former name commonly used for what Ontario now calls a Business Name Registration. It records a business name and associated information with the provincial government.
This distinction matters because someone searching for a “Master Business Licence application” may expect to find a government service using that exact name. The current Ontario Business Registry instead provides services for registering and renewing a business name. Ontario’s own OBR guidance explicitly describes a Business Name Registration as “formally known as a Master Business Licence.”
Registration can apply to several business arrangements, including sole proprietorships, partnerships, and corporations that operate under a business or trade name.
When registering through Ontario’s system, a business may also receive a 9-digit Ontario Business Identification Number (BIN) from ServiceOntario. This should not be confused with the federal Business Number (BN) associated with the Canada Revenue Agency.
Master Business Licence vs. Business Name Registration
| Term | What it means |
| Master Business Licence | Former and still commonly used name |
| Business Name Registration | Current Ontario terminology |
| Ontario Business Registry (OBR) | Online system used to register and manage Ontario businesses |
| BIN | Ontario Business Identification Number issued through ServiceOntario |
| BN | Federal Business Number associated with the Canada Revenue Agency |
The terminology has changed, but someone who says they need to obtain or renew an Ontario Master Business Licence will usually be looking for the province’s Business Name Registration service.
Who Needs to Register a Business Name in Ontario?
Whether you need a Business Name Registration depends primarily on your business structure and the name under which you operate.
Under Ontario’s Business Names Act, an individual generally cannot carry on business or identify their business to the public under a name other than their own name unless that name is registered. Partnerships are also subject to business-name registration requirements, while corporations generally must register a name when operating publicly under a name other than their corporate name.
Consider a hypothetical sole proprietor named Maria Chen. If she operates simply under her personal name in circumstances covered by the statutory exception, her registration requirements can differ from those that apply if she markets the business as “Chen Creative Studio.” The latter introduces a separate business name and may therefore trigger registration requirements.
A corporation presents a different situation. Suppose a company is legally incorporated as “12345678 Ontario Inc.” but sells its services publicly as “North Shore Renovations.” The corporation generally needs to register the operating name because it differs from its corporate name.
The important question is therefore not simply, “Do I own a business?” It is also, “What legal structure do I have, and what name am I using to identify that business to the public?”
What Does an Ontario Business Name Registration Actually Give You?
A Business Name Registration creates a provincial record of the registered business name and related information. It can provide documentation that banks, government programs, suppliers, or other organizations may request when dealing with the business.
It should not, however, be treated as a universal licence allowing the business to conduct every possible commercial activity.
A business may still require municipal, provincial, or federal permits and licences depending on its location and activities. Restaurants, construction businesses, regulated professionals, childcare operations, transportation businesses, and other specialized activities can face requirements beyond basic business-name registration.
Registration also should not be confused with incorporation. A sole proprietorship does not become a corporation simply because the owner registers a business name.
That distinction affects liability, ownership, taxation, and business continuity. Entrepreneurs deciding between a sole proprietorship and corporation should evaluate the business structure separately rather than assuming a Master Business Licence provides the protections associated with incorporation.
How to Get a Master Business License in Ontario
The current route is to register the business through the Ontario Business Registry. Ontario states that businesses with employees, facilities, or offices in the province must register using the OBR.
1. Choose Your Business Structure
Determine the legal structure before beginning the registration process.
Common options include:
- Sole proprietorship
- General partnership
- Limited partnership
- Limited liability partnership
- Corporation
The choice has consequences beyond the registration fee. Ownership, personal liability, tax treatment, administrative obligations, and financing needs can differ significantly between structures.
For someone starting a small one-owner business, a sole proprietorship may be comparatively simple. A growing business with greater liability exposure or multiple shareholders may need to evaluate incorporation with professional legal or accounting advice.
2. Choose and Search Your Business Name
Before submitting a registration, search the Ontario Business Registry to determine whether the proposed name is already being used.
Ontario provides a free OBR search for checking business names.
Do not assume that successfully registering a name automatically gives you broad trademark protection. Business-name registration and trademark rights are separate legal issues.
If the brand name will become a valuable commercial asset, particularly if the business will operate beyond Ontario, trademark considerations may deserve separate attention.
3. Gather the Registration Information
The exact information required depends on the type of business.
For an individual registering a business name, Ontario regulations require information that includes the name being registered, the individual’s full name, relevant business and service addresses, the fact that the activity is being carried on as a sole proprietorship, and a North American Industry Classification System (NAICS) code describing the activity carried on under the name.
Preparing these details beforehand reduces the chance of having to stop midway through the registration.
4. Create the Required Online Accounts
Ontario’s current system uses an Ontario.ca Login and an Ontario Business Account to access the Ontario Business Registry.
For an existing business that needs to be linked to an OBR profile, a company key may also be required. Ontario describes the company key as a confidential 9-digit code unique to the business. The business identifier together with the company key allows an authorized user to link and manage the business through the registry.
Keep the company key confidential. It can give an authorized person, such as an accountant or lawyer, the ability to perform transactions on behalf of the business.
5. Complete the Registration and Pay the Fee
Submit the required information through the Ontario Business Registry and pay the applicable government fee.
Ontario currently lists the following online registration fees:
| Business structure or filing | Ontario online fee |
| Sole proprietorship | $60 |
| General partnership | $60 |
| Ontario limited liability partnership | $60 |
| Extra-provincial limited liability partnership | $60 |
| Ontario limited partnership | $210 |
| Business corporation | $300 |
These amounts are government fees listed by Ontario and can change. Additional costs can also arise depending on the filing. For example, an Ontario business corporation using a named rather than numbered corporation requires an Ontario-biased or weighted Nuans name search report, according to Ontario’s registration guidance.
For Business Names Act registrations such as a new sole proprietorship, general partnership, or business name for a corporation or partnership, Ontario currently lists online processing as immediate and the fee as $60.
How Much Does a Master Business License Cost in Ontario?
For the registrations most people mean when searching for an Ontario Master Business Licence, the government fee is generally $60 for a new online registration of a sole proprietorship, general partnership, or business name for a corporation or partnership.
A renewal of these registrations is also currently $60 when filed online with the ministry. Amendments and cancellations are listed at $0 for these Business Names Act filings.
Be careful when comparing prices online. Private service providers can assist with registrations and charge their own service fees. Those charges are separate from the Ontario government’s filing fee.
The total cost can also be higher when the entrepreneur is actually incorporating a company rather than simply registering a business name. Incorporation is a different filing with different requirements and fees.
How Long Does It Take to Get a Business Name Registration?
Ontario currently lists online new Business Names Act registrations as immediate. Mail filings have a longer listed service time.
That makes online filing the most direct option for many applicants.
However, “immediate” government processing does not necessarily mean the business is ready to start every regulated activity immediately. You may still need other registrations, permits, tax accounts, municipal approvals, insurance, or industry-specific licences before beginning operations.
Think of business-name registration as one part of setting up the business, rather than the final approval for every aspect of its operation.
How Long Is a Master Business License Valid in Ontario?
A Business Name Registration, formerly called a Master Business Licence, is valid for five years.
Ontario currently allows renewal during a window beginning six months before the expiry date and extending to 60 days after expiry.
If the registration remains active or has been expired for fewer than 60 days, the owner can renew through the Ontario Business Registry. The renewal option appears in the account six months before expiry.
This deadline is worth tracking carefully. Ontario states that if a business name has been expired for more than 60 days, the owner will need to complete a new business name registration and register the same business name again rather than simply using the normal renewal process.
How to Renew a Master Business License in Ontario
Renewal is handled through the Ontario Business Registry.
For an existing OBR profile, the basic process is to sign in using your Ontario.ca Login, select the registered business name, and choose the renewal option under the available changes.
Businesses without an existing OBR profile may first need to create the appropriate profile and link the business. A company key can be required for linking an existing business to the account.
The current government fee for renewal of a sole proprietorship, general partnership, or business name for a corporation or partnership is $60 online.
A simple internal reminder several months before the five-year expiry date can prevent a registration from slipping beyond the renewal window.
Master Business Licence vs. Incorporation
A Master Business Licence and incorporation solve different problems.
Registering a business name tells Ontario who is conducting business under that registered name. Incorporation creates a corporation, which is a distinct legal structure.
For example, suppose Alex starts “Alex’s Mobile Detailing” as a sole proprietorship and registers the business name. The registration does not turn the operation into a corporation. Alex remains a sole proprietor.
If Alex instead incorporates an Ontario business corporation, the company is governed by corporate requirements and receives an Ontario Corporation Number. If that corporation then operates under a different public-facing trade name, it may also need to register that business name.
This is why “registering a business” can mean different things depending on context. Someone may be registering a business name, incorporating a corporation, or completing both types of filings.
Ontario BIN vs. CRA Business Number
One of the easiest mistakes for new business owners to make is confusing an Ontario Business Identification Number (BIN) with a federal Business Number (BN).
Ontario specifically states that the 9-digit BIN issued by ServiceOntario is different from the Business Number provided through the Canada Revenue Agency.
The distinction matters when completing government forms or dealing with banks and other organizations. If someone asks for your “business number,” determine which identifier they actually require rather than automatically providing the first number you find on your registration documents.
Does a Master Business License Include HST Registration?
Business-name registration and federal tax registration should be treated as separate processes.
Registering a business name with Ontario does not mean every federal tax account the business might need has automatically been addressed. The federal Business Number system is distinct from Ontario’s Business Identification Number, and tax obligations depend on the business’s circumstances.
A new owner should therefore review applicable Canada Revenue Agency requirements separately, including GST/HST, payroll, corporation income tax, and other accounts where relevant.
This distinction can prevent a common startup error: finishing the provincial name registration and assuming that every tax and regulatory requirement has also been completed.
Do You Need Other Licences After Registering the Business?
Possibly. A Business Name Registration does not eliminate industry-specific or location-specific licensing requirements.
A home-based consultant may have a relatively simple regulatory profile, while a restaurant, contractor, childcare provider, transportation company, or other regulated operation can face additional requirements.
Before opening, check requirements based on:
- The municipality where the business operates
- The products or services being sold
- Whether employees will be hired
- Whether the business operates from a commercial or residential property
- Whether the occupation or industry is regulated
- Whether federal permits or registrations apply
The safest approach is to separate business-name registration from permission to conduct a particular regulated activity. They are not necessarily the same thing.
Common Mistakes When Registering a Business in Ontario
One frequent mistake is assuming that a Master Business Licence is a general licence for every type of business activity. It is primarily a business-name registration, while separate permits or licences may still apply.
Another is confusing a BIN with a CRA Business Number. The abbreviations look similar, but the numbers belong to different government systems.
Business owners can also overlook the five-year expiry period. Because renewal is not an annual task, it can be easier to forget. Recording the expiry date in a compliance calendar helps avoid losing the normal renewal option.
Other problems arise when owners assume registering a name gives them the same legal protection as incorporating or the same brand protection as registering a trademark. These are separate legal concepts with different purposes.
Finally, avoid paying an unnecessary third-party markup without understanding what you are purchasing. A private filing service may be useful if you want assistance, but its service charge is not the same as Ontario’s government filing fee.
Practical Checklist for an Ontario Business Name Registration
Before registering, confirm your intended ownership structure and the exact business name you plan to use. Search the Ontario Business Registry, collect the owner’s or partners’ information and required addresses, determine the appropriate NAICS code, and have a valid payment method ready.
After registration, save your registration documents and relevant Ontario identifiers in a secure location. Determine whether CRA accounts are required, investigate municipal and industry-specific licences, and record the five-year expiry date.
For an existing business, also protect the company key and ensure that the correct people have authority to manage the business through the Ontario Business Registry.
This approach turns registration from an isolated filing into part of a broader compliance process.
Conclusion
A master business license in Ontario is now officially handled as a Business Name Registration through the Ontario Business Registry. For common registrations such as a sole proprietorship or general partnership, the current online government fee is $60, and the registration is generally valid for five years.
Before filing, choose the correct business structure, confirm whether the name must be registered, and gather the required information. After registration, remember that the document is not a substitute for incorporation, CRA tax registrations, trademarks, or industry-specific permits and licences.
Because business registration requirements and government fees can change, verify the current requirements through the Ontario Business Registry and Ontario business registration guidance before submitting a filing. For situations involving liability, ownership structure, taxes, or legal rights to a business name, professional legal or accounting advice may also be appropriate.
