An Ontario trade name registration – also called a business name – lets you operate and market your company under a name that isn’t your personal legal name or your corporation’s registered legal name. It gives you a consistent, ownable identity to build customer recognition around, and it’s a legal requirement under Ontario’s Business Names Act the moment you use anything other than your own full name to do business. If you use any name other than your full legal name, you must register that name under the Business Names Act. Skipping this step doesn’t just create a legal gap – it undercuts the entire branding effort you’re trying to build.
What Exactly Is a Trade Name in Ontario?
A trade name is the public-facing name customers see, use, and remember – think “Jane’s Catering” instead of “Jane Smith,” or “Maple Leaf Web Studio” instead of a numbered corporation. It’s distinct from your legal name (for sole proprietors) or your corporate name (for incorporated businesses).
Here’s the distinction that trips up a lot of new entrepreneurs:
- Legal name / corporate name: The name on your official government filing. For a corporation, this is what appears in your Articles of Incorporation.
- Trade name / operating name: The name on your storefront, website, invoices, and marketing. It has no legal status on its own unless registered.
A corporation that only uses its official corporate name does not need a separate Business Names Act registration at all – but the second that corporation starts marketing under a different brand name, that name has to be registered too.
How Does a Trade Name Help You Set Up Your Brand?
A registered trade name gives your brand three things a legal or corporate name usually can’t: memorability, ownership, and legitimacy. It lets you separate your personal identity from your business identity, choose a name that actually communicates what you do, and put a real, searchable record behind it that banks, suppliers, and customers can verify.
From a branding standpoint, this matters more than most entrepreneurs expect. Notes that a clean, registered trade name is often the first trust signal a small business gives a potential client – before a website, before a logo, before a single sale. When a customer searches your business name and finds it correctly registered on the Ontario Business Registry, that small detail quietly answers the “is this a real business?” question before you ever have to.
A trade name also gives you room to reposition. If your legal name is “Kowalski Consulting Inc.” but you want to market under “Northline Strategy,” registering that trade name lets your brand evolve without touching your corporate structure, contracts, or tax filings.
📝 How Do You Register a Trade Name in Ontario? (Step-by-Step)
Registering a trade name in Ontario is completed through the Ontario Business Registry. Whether you're starting a sole proprietorship, partnership, or corporation, the registration process follows the same basic steps.
1️⃣ Choose Your Business Name
Select a name that is distinctive and not easily confused with existing businesses. Avoid generic or misleading names that could create legal or branding issues.
2️⃣ Search the Ontario Business Registry
Use the free Ontario Business Registry search to check whether your proposed business name is already registered before submitting your application.
3️⃣ Choose Your Business Structure
Decide whether you're registering a sole proprietorship, partnership, or corporation, as this determines the registration process and applicable government fee.
4️⃣ Create Your Ontario.ca Account
Set up an Ontario.ca Login and an Ontario Business Account to access the Ontario Business Registry and complete your filing online.
5️⃣ Submit Your Application & Pay
Government fees currently start at approximately $60 for sole proprietorships and partnerships, while corporations generally pay $300. Online applications are usually processed quickly.
6️⃣ Receive Your Master Business Licence (MBL)
Once approved, you'll receive your Master Business Licence, confirming your business name has been officially registered in Ontario.
7️⃣ Renew Every 5 Years
Trade name registrations are valid for five years. ServiceOntario generally sends a renewal reminder about 90 days before the registration expires.

How Much Does It Cost to Register a Trade Name in Ontario?
| Business structure | Government fee | Validity period | Renewal fee |
|---|---|---|---|
| Sole proprietorship | $60 CAD | 5 years | $60 CAD |
| General partnership | $60 CAD | 5 years | $60 CAD |
| Limited Liability Partnership | $60 CAD | 5 years | $60 CAD |
| Ontario Limited Partnership | $210 CAD | 5 years | $210 CAD |
| Corporation (operating name) | $60 CAD (only needed if operating under a name different from your corporate name) | 5 years | $60 CAD |
Note that a corporate registration itself, separate from a trade name, costs $300 online and covers the legal entity – not the brand name it markets under.
What Happens If You Don’t Renew Your Trade Name?
This is the part that quietly damages brands more often than people realize. If your MBL expires without renewal, your business name registration lapses. You can re-register under the same name if it’s still available, but there is no grace period – once lapsed, the name is available to others.
In practice, this means a competitor – or anyone else – can legally register your exact trade name the day after it lapses. Years of brand equity, Google reviews, signage, and word-of-mouth can be tied to a name you no longer have exclusive claim to. Set a calendar reminder well before the 90-day renewal notice arrives; don’t rely on ServiceOntario’s mail as your only trigger.
Trade Name vs. Trademark: What’s the Difference?
A registered trade name is not the same as a trademark, and this is one of the most common misconceptions among Ontario entrepreneurs.
- Trade name registration confirms you’re operating under that name in Ontario and satisfies the Business Names Act. It does not grant exclusive rights to the name across Canada or prevent someone in another province from using it.
- Trademark registration (through the Canadian Intellectual Property Office) gives you exclusive national rights to use that name, logo, or slogan in connection with specific goods or services.
If your brand strategy depends on the name itself – not just local operation – a trade name registration alone won’t protect it. Many growing Ontario businesses register the trade name first to start operating, then pursue a trademark once the brand has traction worth protecting.
💡 A Practical Example
A common pattern: a sole proprietor starts under their own name, tests the business idea with minimal setup, then registers a trade name once they've validated demand and want a name that's easier to market and remember.
The trade name search step matters here - a name that's technically available on the Ontario registry can still infringe an existing trademark elsewhere.
A quick check of the Canadian Trademarks Database alongside your Ontario search is worth the extra ten minutes, especially if you plan to sell online or expand beyond Ontario.
Frequently Asked Questions
What is an Ontario trade name search, and why do I need one?
An Ontario trade name search checks the Ontario Business Registry to confirm your desired business name isn't already registered by another entity. Provincial registration is only the first layer of protection, so this search reduces - but doesn't eliminate - the risk of naming conflicts.
How long does Ontario trade name registration take?
Online filings are processed almost immediately once submitted through the Ontario Business Registry, provided your documentation and name search are complete.
Do I need a trade name if I'm a corporation?
Only if you operate under a name different from your corporate name. A corporation that only uses its official corporate name does not need a separate Business Names Act registration at all.
Can someone else take my trade name if I forget to renew it?
Yes. There is no grace period - once your registration lapses, the name is available to others to register.
Is a registered trade name the same as a trademark?
No. A trade name registration satisfies Ontario's Business Names Act and confirms provincial operation; a trademark, filed federally, protects exclusive use of the name across Canada. Many businesses need both as they grow.
