Business name registration in Ontario is generally required when a sole proprietor, partnership, or corporation operates under a name different from its legal name. It highlights that registration is completed through the Ontario Business Registry, currently costs $60 for a sole proprietorship or general partnership, and is separate from incorporation, CRA registration, and trademark protection.
When Do You Need to Register a Business Name in Ontario?
Ontario’s Business Names Act generally requires an individual to register a business name when carrying on business under a name other than the individual’s own name. A partnership must register its firm name, and a corporation must register a separate operating name if it carries on business or identifies itself to the public under a name other than its corporate name.
For example, suppose Sarah Chen starts providing bookkeeping services simply as Sarah Chen. Depending on how she operates, she may not need a separate business name registration merely to use her own name. If she instead markets the business as Maple Ledger Bookkeeping, that operating name generally needs to be registered.
A corporation can face the same requirement. If 12345678 Ontario Inc. runs a retail business using the public-facing name Northern Trail Outfitters, the corporation would generally register Northern Trail Outfitters as a business name.
Business name registration does not change the underlying legal structure. A registered sole proprietorship remains a sole proprietorship, and registering an operating name for a corporation does not create a second corporation.
How Much Does Business Name Registration Cost in Ontario?
The Ontario government currently charges $60 for online registration of a sole proprietorship or general partnership through the Ontario Business Registry. Other business structures have different filing fees.
| Business type | Ontario government registration fee |
| Sole proprietorship | $60 |
| General partnership | $60 |
| Ontario limited liability partnership | $60 |
| Extra-provincial limited liability partnership | $60 |
| Ontario limited partnership | $210 |
| Business corporation incorporation | $300 |
These are Ontario government filing fees. Third-party service providers may charge additional service fees if you use them instead of filing directly with the province.
A sole proprietor who only needs a business name should therefore distinguish the $60 business name registration from the $300 Ontario incorporation fee. Incorporation establishes a corporation as a separate legal entity, while registering a sole proprietorship’s business name does not.
Choose Your Business Structure Before Registering the Name
Before filing a business name registration in Ontario, decide whether the business will operate as a sole proprietorship, partnership, or corporation. The structure affects ownership, tax reporting, liability, administrative obligations, and registration costs.
A sole proprietorship is an unincorporated business owned by one individual. The Canada Revenue Agency explains that the owner receives the profits, claims the losses, makes the business decisions, and assumes the risks of the business. The business does not have separate legal status from its owner.
A partnership involves two or more parties carrying on business together. Depending on the circumstances, a partnership agreement can be valuable for defining ownership percentages, decision-making authority, profit distribution, responsibilities, and procedures for a partner leaving the business.
A corporation is legally distinct from its shareholders. Registering a business name is therefore not a substitute for incorporation if your objective is to establish a corporation.
Business Name Registration vs. Incorporation
| Issue | Registering a sole proprietorship name | Incorporating in Ontario |
| Creates separate corporation | No | Yes |
| Ontario government filing fee | $60 | $300 |
| Separate legal entity | No | Yes |
| Owner generally reports business income personally | Yes | No, corporation files its own corporate return |
| Name registration may expire | Yes | Corporation continues subject to applicable corporate requirements |
| Personal liability protection from corporate structure | No | Generally available, subject to important exceptions |
| Named Ontario corporation normally needs Ontario-biased/weighted Nuans report | No | Yes, unless using a numbered name |
The choice should be based on the actual business circumstances rather than the attractiveness of a business name. Businesses with significant contractual risk, multiple owners, investors, employees, valuable assets, or complex tax considerations may benefit from professional legal or accounting advice before choosing a structure.
Search the Business Name Before You Register It
Ontario recommends searching the Ontario Business Registry before registering a business name. The government’s online registration guidance states that users can search the registry for free to determine whether a business name is already taken.
A name appearing available in one search should not automatically be treated as legally safe to use. Business names, corporate names, trademarks, and domain names are different forms of identification, and conflicts can arise beyond the provincial business registry.
Canada’s business-name guidance recommends checking national corporate names and trademarks through resources such as Nuans and Canada’s business registries when choosing a name.
Before committing to branding, consider checking:
- The Ontario Business Registry.
- Canada’s business registries.
- The Canadian Trademarks Database or relevant trademark searches.
- Common internet search results.
- Relevant domain-name availability.
- Social-media usernames if those channels will be important to the brand.
This broader search is particularly useful if you intend to invest substantial money in signage, packaging, advertising, a website, or branded inventory.
Do You Need a NUANS Report to Register a Business Name?
A Nuans report is generally associated with incorporating a named Ontario corporation, rather than registering an ordinary sole proprietorship or general partnership business name.
Ontario states that a person incorporating a business corporation under a name rather than a numbered designation must obtain an Ontario-biased or Ontario-weighted Nuans name search report. A federal Canada-biased Nuans report is not accepted for that Ontario incorporation process.
Ontario regulations also require the relevant Nuans report supporting a proposed corporate name to be dated no more than 90 days before the articles are submitted.
That distinction prevents a common mistake:
Registering “Blue Pine Consulting” as a sole proprietorship: generally does not require the corporate Nuans process described above.
Incorporating “Blue Pine Consulting Inc.” as an Ontario corporation: generally requires the Ontario-biased or weighted Nuans report unless a numbered corporation is used.
If your goal is simply to register a business name for an unincorporated business, do not assume you need to purchase a Nuans report merely because you have seen it mentioned in incorporation guides.
Gather the Information Needed for Ontario Business Registration
The exact information requested can depend on the business structure, but you should prepare the core details before starting the online filing.
Ontario’s online registration system requires a working email address and an accepted form of payment. Users registering through the Ontario Business Registry are also guided through creating an Ontario.ca Login and Ontario Business Account.
For a typical sole proprietorship registration, prepare information such as:
- Your proposed business name
- Business activity or description
- Principal place of business address
- Owner’s legal name and required identifying information
- Contact information
- Email address
- Payment method
- Effective or relevant business information requested during the filing
Review every entry carefully before submitting it. The name, spelling, ownership details, and address you file become part of the business’s official registration information.
Register the Business Through the Ontario Business Registry
Ontario business registrations are handled through the Ontario Business Registry.
The basic process is:
1. Create or Sign In to Your Ontario.ca Login
An Ontario.ca Login provides secure access to provincial online services. Once signed in, you can create an Ontario Business Account and use the Ontario Business Registry.
2. Search Your Proposed Business Name
Search the Ontario Business Registry to identify existing businesses using the same or similar names. A registry search does not replace a broader trademark and brand-clearance review, but it is a sensible first step.
3. Select the Appropriate Business Type
Choose the structure you are actually registering, such as a sole proprietorship or general partnership.
Do not select “Business Corporation” simply because you want a professional business name. Incorporating and registering an unincorporated business name have different legal consequences.
4. Enter the Requested Business Information
Provide the business name, address, ownership and other required filing information accurately.
Consistency matters. For example, if your official registration says Green Harbour Media, avoid unnecessarily switching between versions such as Green Harbor Media, Green Harbour Marketing, and GreenHarbour Media on legal or financial documents.
5. Pay the Registration Fee
For an Ontario sole proprietorship or general partnership, the provincial online registration fee is currently $60. Ontario accepts online payment by Debit, Visa or Mastercard for applicable services.
6. Save Your Registration Documents and Identification Information
Keep electronic and backup copies of the registration confirmation and related identifiers. You may need your business information later when dealing with government services, banking providers, insurers, payment processors, vendors, accountants, or other organizations.
Ontario issues a nine-digit Business Identification Number (BIN) through ServiceOntario. This is different from the federal Business Number (BN) administered by the Canada Revenue Agency.
Ontario BIN vs. CRA Business Number: Do Not Confuse Them
Business owners frequently encounter two identifiers with similar names.
An Ontario Business Identification Number (BIN) is associated with the provincial registration.
A federal Business Number (BN) is administered by the Canada Revenue Agency and is used for CRA program accounts and other government interactions.
| Identifier | Issued by | Typical purpose |
| Business Identification Number (BIN) | ServiceOntario | Ontario business registration identification |
| Business Number (BN) | Canada Revenue Agency | Federal business identification and CRA program accounts |
| GST/HST account | CRA | GST/HST registration, built around the BN |
| Payroll program account | CRA | Payroll deductions and remittances |
Not every unincorporated business needs a CRA Business Number immediately. CRA states that an unincorporated business generally needs a BN when it registers for a CRA program account, such as GST/HST or payroll. A corporation, by contrast, needs a BN as part of its tax and government-account framework.
This means completing Ontario business name registration does not necessarily complete every tax registration your business may require.
How Long Is an Ontario Business Name Registration Valid?
An Ontario business name registration is effective for five years from the date the Registrar accepts it.
You can renew the registration before it expires. Ontario’s current registry guidance states that renewal costs the same as a new registration for the relevant business type, including $60 for a sole proprietorship or general partnership.
If the registration has been expired for more than 60 days, Ontario says it can no longer be renewed through the normal renewal process. Instead, the business name must be registered again. The new registration results in a new BIN and company key.
A practical approach is to record the expiry date somewhere other than your registration document, such as in a business compliance calendar.
Update Your Registration When Business Information Changes
Registration is not necessarily a one-time administrative task.
Ontario’s Business Names Act requires a registrant to file an amended registration when information contained in the registration changes. The legislation specifies that the amended registration must generally be made within 15 days after the change.
Changes could involve information such as an address or other registered particulars, depending on the business and filing.
The Ontario Business Registry supports transactions including updating company information, renewing a registration, and cancelling or dissolving applicable business registrations.
Maintaining current records is particularly important if government notices or other official communications depend on information associated with the registration.
Does Registering a Business Name Give You Trademark Protection?
No. Registering an Ontario business name should not be treated as equivalent to obtaining a registered trademark.
The Canadian Intellectual Property Office distinguishes trademarks from business and company names. CIPO states that registering a domain name or incorporating a business does not itself provide trademark rights. A trade name can potentially be registered under the Trademarks Act when it is also used as a trademark to distinguish goods or services.
Federal business-name guidance likewise explains that provincial or territorial trade-name registration does not provide exclusive federal rights to that name.
Consider the practical difference:
A business owner registers Northstar Garden Supply as an Ontario sole proprietorship. That registration records the business name provincially, but it should not be interpreted as a nationwide monopoly over every use of “Northstar Garden Supply.”
If the name will become an important brand asset, a trademark search and, where appropriate, professional advice about trademark registration may be worthwhile before investing heavily in the brand.
Do You Need to Register for HST After Registering the Business?
Business name registration and GST/HST registration are separate processes.
For most businesses, CRA’s current small-supplier rules generally mean mandatory GST/HST registration begins when taxable revenues exceed the applicable $30,000 threshold, subject to the way and period in which the threshold is exceeded and other exceptions.
A small supplier making taxable supplies can generally register voluntarily before reaching the mandatory threshold. Once voluntarily registered, the business assumes obligations such as charging, collecting and remitting GST/HST on taxable supplies and filing GST/HST returns. CRA states that a voluntarily registered business generally must remain registered for at least one year unless it stops its commercial activities.
Some industries and activities have different GST/HST rules, so do not rely on the $30,000 figure without considering the nature of the business.
For example, registering an Ontario sole proprietorship today does not automatically mean the owner must immediately charge HST simply because the business name has been registered.
What Should You Do After Registering Your Ontario Business Name?
Registration establishes the provincial business-name record, but it is only one part of setting up a functioning business.
After registering, consider whether you need to:
- Obtain a CRA Business Number or CRA program accounts
- Register for GST/HST
- Open a payroll account before paying employees
- Obtain municipal licences or permits
- Obtain industry-specific provincial licences
- Open an appropriate business bank account
- Arrange commercial insurance
- Create contracts, estimates, invoices and payment terms
- Set up bookkeeping and tax records
- Check trademark risks
- Register relevant domain names
- Update contracts or registrations when business details change
Which steps apply depends heavily on the business.
A freelance designer working alone from home may have relatively few additional regulatory requirements. A restaurant, construction contractor, childcare provider, transportation company, regulated professional, or employer may face substantially more licensing, insurance, tax, zoning, safety, or employment obligations.
Business name registration should therefore be viewed as one registration within a wider compliance process, not as a general licence to conduct every type of business activity.
Common Business Name Registration Mistakes to Avoid
Assuming Registration Means the Name Is Legally Exclusive
A registered Ontario business name is not the same as a registered trademark. Search for potential conflicts before building substantial brand value around the name.
Incorporating When You Only Intended to Register a Sole Proprietorship
The $60 sole-proprietorship registration and $300 Ontario incorporation are different filings with different legal consequences.
Confusing the Ontario BIN With the CRA BN
The provincial Business Identification Number and CRA Business Number serve different purposes. Record both clearly if your business eventually has both.
Forgetting the Five-Year Expiry Date
Ontario business name registration does not remain active indefinitely. Track your renewal date so you do not accidentally allow it to lapse.
Missing the 60-Day Late-Renewal Window
Once a registration has been expired for more than 60 days, Ontario says you must register the business name again rather than renew the old registration.
Failing to Update Changed Information
The Business Names Act generally requires amended registration information within 15 days after a relevant registered detail changes.
Assuming Registration Covers Taxes and Licences
Registering a name does not automatically satisfy CRA, municipal, professional, zoning, employment, or industry-specific requirements.

Conclusion
Business name registration in Ontario is relatively straightforward for most sole proprietors and general partnerships: choose the appropriate business structure, check the proposed name, create access to the Ontario Business Registry, provide the required information, and pay the current $60 provincial registration fee.
The more important decisions happen around the registration itself. Confirm whether you actually need a sole proprietorship, partnership or corporation, distinguish your Ontario BIN from a CRA Business Number, assess GST/HST and licensing requirements separately, and remember that registering a business name does not automatically provide trademark protection.
Once registered, record the five-year expiry date and keep your information current. Those simple compliance steps can prevent a small registration task from turning into a larger administrative problem later.
