A Master Business Licence in Ontario is the historical name for what is now officially called a Business Name Registration. It allows an individual, partnership, or corporation to legally operate under a registered business name and is valid for five years. This registration is required for most Sole Proprietorships, General Partnerships, and trade names registered under existing corporations.
Master Business Licence Registration in Ontario: What It Is, Who Needs It, & How to Get One
If you’re starting a business in Ontario, you may have come across the term Master Business Licence. While the Province now officially refers to this as a Business Name Registration, many entrepreneurs, banks, and institutions still use the older term. Both refer to the same registration under Ontario’s Business Names Act.
A Master Business Licence (Business Name Registration) allows you to legally operate a business under a name that is not your personal legal name. It is required for most Sole Proprietorships, General Partnerships, and trade names registered under an existing corporation.
Below, we explain exactly what a Master Business Licence is, who needs one, how to register, renewal requirements, and when incorporating may be a better option.
What Is a Master Business Licence in Ontario?
A Master Business Licence (MBL) is the historical name for what is now called a Business Name Registration in Ontario. It registers a business name with the Province and creates a record in the Ontario Business Registry.
This registration:
- Links your business name to its owner(s)
- Issues a Business Identification Number (BIN)
Allows the business to operate legally under that name
Although the terminology has changed, “Master Business Licence” remains a widely searched and commonly used phrase, which is why it’s still referenced today.
Who Needs a Master Business Licence?
You are required to register a Master Business Licence (Business Name Registration) if you are operating as:
- A Sole Proprietorship using a business name other than your full legal name
- A General Partnership
- A trade name under an existing corporation (also called a “business name under a corporation”)
If you are operating solely under your exact personal legal name with no additions, registration may not be required. However, most businesses choose to register to ensure clarity, professionalism, and compliance.
What Does a Master Business Licence Allow You to Do?
Registering a Master Business Licence allows you to:
- Operate legally under your chosen business name
- Open a business bank account
- Register for tax accounts (HST, payroll, import/export, where applicable)
- Enter into contracts under the business name
- Provide proof of registration to banks, suppliers, and institutions
What a Master Business Licence Does Not Provide
It’s important to understand the limitations:
- ❌ No name protection — other businesses may register similar or identical names
- ❌ No limited liability — the owner(s) are personally responsible for debts and obligations
- ❌ No corporate tax advantages
This is one of the most common reasons business owners later transition from a Sole Proprietorship to a Corporation.
Types of Master Business Licence / Business Name Registration
When you register an Ontario business licence, there are three structures available. Here’s how to get a business license in Ontario for each option.
- Sole Proprietorship: For a single business owner operating individually. Registering a sole proprietorship is often the simplest option for small businesses.
- General Partnership: For two or more owners sharing responsibilities in the business.
- Trade Name: For an existing corporation that wishes to operate under an additional business name.
A master business license in Ontario is easy and affordable to obtain. The Government of Ontario provides the documents directly by email. You can apply through Service Ontario for a Master Business Licence online, making it simple to register and operate legally in the province.
How to Register a Master Business Licence in Ontario
Registering a Master Business Licence (Business Name Registration) is straightforward. The process includes:
How to Register a Master Business Licence in Ontario
- Choose your business structure
- Confirm your business name meets Ontario requirements
- Submit the registration electronically
- Receive your Business Name Registration document
- Save your Company Key for future updates and renewals
What Information is on a Master Business Licence?
Once your Business Name Registration or Master Business License is complete, you’ll receive a PDF document. This includes your business name, address, owner name(s), and your specific business activity. Additionally, it will list a Business Identification Number (BIN), which is unique to each Ontario Master Business License. Use this number to make amendments or renew the Master Licence in Ontario every five years.
If you have a Trade Name, the document will show the corporate entity linked to it. A BNR does not provide name protection in Ontario. It may be beneficial to conduct a company name search in Ontario before registering to avoid potential conflicts.
We often receive the question “Do I need a business license in Ontario?”. If you operate using anything other than your legal name, your business requires a registration to use that name.

Benefits & Limitations of a Master Business Licence or Business Name Registration
A Master Business License in Ontario, Canada allows small business owners to access essential business services and resources. While a MBL or Business Name Registration provides benefits, it’s important to know its limitations too.
Benefits
- 5-Year Registration: With simple renewals every five years, this is a straightforward option for most.
- Proof of Business Operations: You can use your MBL to open a business bank account, apply for tax accounts, and qualify for wholesale pricing with suppliers.
- Access Government Support: You may be eligible to apply for business grants with a registered business name.
Limitations
- No Name Protection: Unlike incorporated businesses, sole proprietorships and general partnerships don’t have exclusive rights to their business name.
- No Limited Liability: Unlike a corporation, a MBL is not a separate legal entity from the business owners. It does not offer protection from personal liability, which may be a consideration for some businesses.
- No Corporate Tax Benefits: Some tax advantages apply only to corporations, not sole proprietors or partnerships.
Master Business Licence vs Corporation
Many entrepreneurs ask whether they should register a Business Licence or incorporate.
A Business Licence may be suitable if:
- You are just starting out
- Your business is low risk
- You want minimal setup costs
Incorporation may be better if:
- You want limited liability protection
- Your business is growing
- You want tax deferral or income-splitting options
- You want stronger name protection
The right choice depends on your business goals, risk level, and long-term plans.
| Master Business Licence | Corporation |
| No liability protection | Limited liability |
| No name protection | Name protection |
| 5-year validity | Continuous |
| Personal tax rates | Corporate tax rates |
If you decide that incorporating is the better option for your business, Ontario Business Central can also assist with completing an Ontario incorporation and help you through this process.
New Requirements in the Ontario Business Registry (OBR)
Ontario’s Business Registry system issues a unique company key with each new registration. Store this company key securely, as it functions like a password. With the company key, you can easily update business information, renew your registration, or change your business activity. Businesses with a master license in Ontario that do not have a company key can apply to receive a key.
What Is a Company Key & Why Does It Matter?
Since the launch of the Ontario Business Registry (OBR), every Business Name Registration is issued a Company Key.
The Company Key is required to:
- Renew a registration
- Update business details
- Cancel a registration
Without the company key, filings cannot be completed. If misplaced, it must be retrieved before proceeding.
How Much is a Business License in Ontario?
The government fee for registration is $60.00. The total price can vary depending on if you include options like a preliminary name search or tax account set up. Our Business Name Registration page allows you to build your own package to see the total price.
How to Get a Copy of a Master Business License in Ontario?
Replacement copies of your Business Name Registration are only available if you registered or renewed after October 19, 2021. You can find these replacements under Due Diligence Searches listed as “Ontario Business Name Searches”.
Help with CRA Accounts
When you register your master business license, Ontario Business Central can assist with setting up your CRA accounts. This includes obtaining a Business Number (BN), GST/HST registration, or payroll accounts. For Sole Proprietorships and Partnerships, your personal SIN links to the BN.
For Trade Names, the corporation links to the CRA accounts instead. This difference influences how you report your business income and expenses. When you incorporate in Ontario, the Service Ontario Business Registry requests a BN from the CRA on your behalf.
Renewing Your Master Business Licence
Your Ontario Master Business Licence or Business Name Registration in Ontario is valid for five years before it must be renewed.
A 60-day grace period after the expiration date allows for late renewal without penalty. After this period, the license expires, requiring a new registration with a new BIN and creation date. Ontario Business Central will notify you before the expiry date to help you renew on time. Our website offers the option to renew your Master Business License in Canada using our service.
