As of May 2026, if your Ontario Master Business Licence (now known as a Business Name Registration) has expired and is cancelled, it cannot simply be renewed. You must file a completely new registration through the Ontario Business Registry (OBR), which generally incurs a provincial government fee of $60 CAD.
Operating a sole proprietorship or a general partnership under a business name requires strict compliance with provincial registration laws. Whether you run a local bakery in Mississauga, a consulting firm in Toronto, or a landscaping service in Ottawa, your business name must be actively registered. Under the Business Names Act, these registrations are only valid for five years, and failing to renew them on time results in an automatic cancellation.
When a cancellation occurs, you lose your legal right to operate under that specific name until the situation is rectified. 📝 This guide outlines the exact step-by-step process to secure your business identity once again, ensuring your commercial banking, tax accounts with the CRA, and daily operations face minimal disruption.
Step-by-Step Process in Ontario
Restoring a cancelled business name is fundamentally the same process as starting a new one. Because the previous registration has officially lapsed, the provincial registry treats your application as a brand-new entity claim. You must be proactive to prevent another entrepreneur from legally taking your established brand name while it is unprotected.
Step 1: Verifying the Cancellation Status
Before proceeding, you should confirm that your registration is genuinely cancelled and not just pending a grace period. You can do this by searching your business name or Business Identification Number (BIN) / Entity Number on the online Ontario Business Registry (OBR). If the status is marked “Inactive” or “Cancelled,” you must immediately prepare for a fresh filing.
Step 2: Conducting a New Name Search
Because your old name is now technically back in the public pool, it is highly recommended to perform a new preliminary name search. 📎 This ensures no other corporation or individual has registered the exact same or a confusingly similar name in Ontario during the time your licence was lapsed. You can utilize the Enhanced Business Name Search tool on the OBR platform to verify availability.
Step 3: Gathering Required Documentation
Prepare the essential details needed for the new application. You will need your personal contact information, a valid primary address in Ontario (P.O. boxes alone are generally not accepted), and a brief description of your core business activities. If you are registering a general partnership, you must also gather the full legal names and addresses of all acting partners.
Step 4: Filing the New Business Name Registration
With your details ready, navigate to the ServiceOntario or OBR online portal to file the “Register a Business Name” form. 💻 You must input the exact name you operated under previously. Once you pay the provincial government fee and submit the application, the system typically generates a new Master Business Licence (now a digital Business Name Registration document) and assigns you a new Business Identification Number (BIN).
Step 5: Updating Your Bank and the CRA
Because your newly registered business will have a different BIN than your old one, you must notify your commercial bank and the Canada Revenue Agency (CRA). Most financial institutions will require a copy of the new registration certificate to keep your business checking accounts active. You must also link this new provincial registration to your existing federal CRA Business Number for GST/HST and payroll purposes.
How Much Does it Cost in Ontario?
The costs to re-register a cancelled business name are relatively straightforward and primarily consist of government filing fees. Below is a breakdown of what you can expect to pay in Canadian dollars (CAD) as of May 2026.
| Expense | Estimated Cost (CAD) | Details |
|---|---|---|
| OBR Registration Fee | $60 | Provincial fee for a 5-year registration. |
| Name Search Fee | $8 – $15 | Optional but highly recommended database search. |
| Law Firm / Agent Service Fee | $150 – $300 | If you hire a professional to file on your behalf. |
| Bank Update Fees | $0 – $25 | Possible administrative fees from your local bank branch. |
How Long Does the Process Take?
If you utilize the Ontario Business Registry online portal, the process is incredibly fast. In most cases, a new Business Name Registration is issued immediately upon payment clearance, allowing you to download the digital certificate within minutes. If you choose to apply via physical mail to the Ministry of Public and Business Service Delivery, processing can take 4 to 6 weeks, which is not recommended if you need immediate banking access.
Frequently Asked Questions (FAQ)
What happens to my old Business Identification Number (BIN)?
When a Master Business Licence is cancelled, the BIN associated with it becomes permanently inactive. Your new registration will generate a brand-new 9-digit BIN, which you must use for all future provincial compliance.
Can someone else register my cancelled business name?
Yes. Once your registration expires and is cancelled, the name loses its legal protection. Any other resident or corporation in Ontario can legally register that name, which is why acting swiftly to re-register is critical.
Does a cancelled licence affect my CRA tax accounts?
Your federal CRA Business Number (used for HST and corporate taxes) remains active even if your provincial name registration lapses. However, you must inform the CRA once you receive your new provincial registration to ensure their records reflect your current legal operating status.
Do I need a lawyer to register a business name?
Generally, you do not need a lawyer to file a simple sole proprietorship or general partnership registration. However, if your business structure is complex, or you wish to incorporate to gain better liability protection, consulting a business law firm is highly recommended.
Can I backdate my new registration to cover the lapsed period?
No. The Ontario Business Registry does not allow retroactive registrations. Your new licence will be effective from the exact date your application is processed and approved.
