The short answer: only if you use a business name that differs from your legal name. “Master Business Licence” is an Ontario-specific term that has since been officially renamed — but the requirement and its purpose remain the same across Canada.
What Is a “Master Business Licence”?
In Ontario, the document issued when you register a business name used to be called a Master Business Licence (MBL). As of 2021, Ontario officially renamed it the Business Name Registration certificate. The document serves the same purpose — it is proof that you have registered a trade name with the provincial government.
Other provinces have their own equivalent documents:
- British Columbia: Statement of Registration (Sole Proprietorship)
- Alberta: Certificate of Trade Name Registration
- Quebec: Immatriculation certificate from the Registraire des entreprises
Regardless of province or what it is called, the function is the same: it proves your business name is registered and authorizes you to operate under that name.
When Do You Actually Need One?
You need a Business Name Registration (or equivalent) in your province if:
- You operate under any business name other than your own full legal name
- You want to open a business bank account under a business name (banks require proof of registration)
- You want to sign contracts as a registered business entity
- You plan to accept payments made out to a business name rather than your personal name
You do not need one if:
- You freelance exclusively under your own legal name (“Jane Smith”)
- You are incorporated — incorporation already registers your corporate name (though you may separately register a trade name if the corporation operates under a different name)
Is It Required by Law?
Yes — in most provinces, operating a business under a trade name without registering it is a legal offence under provincial business names legislation. In Ontario, for example, the Business Names Act requires registration of any trade name used in business, with fines for non-compliance.
In practice, enforcement against small freelancers is rare. But the practical consequences of not registering are real: banks will not open accounts under unregistered names, and some clients will not pay invoices from unregistered businesses.

Business name registrations expire in most provinces and must be renewed:
- Ontario: 5 years — renewal costs $60
- Quebec: 5 years — renewal required through REQ
- Manitoba: 3 years
- Saskatchewan: 10 years
- BC and Alberta: No expiry, but must be updated if name or address changes
An expired registration can prevent you from renewing a business bank account or cause issues with client contracts. Set a calendar reminder for renewal at least 3 months before expiry.
Frequently Asked Questions
Does my Business Name Registration give me exclusive rights to my name?
No. Sole proprietorship name registration does not give you exclusive rights — another business can register the same or a similar name in the same province. For exclusive rights to a name, you need to incorporate (which grants name protection within the province or nationally for federal corporations) or register a federal trademark.
Can I use a Business Name Registration certificate to open any Canadian bank account?
Most Canadian banks accept a valid provincial Business Name Registration certificate to open a business bank account. Some banks may also accept incorporation documents for incorporated businesses. Always call ahead to confirm what documentation your specific bank branch requires.
Is the Ontario Business Identification Number (BIN) the same as a CRA Business Number?
No. Ontario’s BIN (on your Business Name Registration certificate) is a provincial identifier for Ontario registry purposes. The CRA Business Number is a separate 9-digit identifier for federal tax purposes. You may have both — they are issued by different governments and serve different functions.
