An Ontario trade name (also called a business name) is simply the legal label you put on invoices, signage, and government forms so the province knows who’s operating behind the name. A trademark is a completely different tool — it’s intellectual property protection for the brand elements (names, logos, slogans) that customers use to distinguish you from competitors. Registering a trade name in Ontario does not give you any ownership rights over that name; only a trademark does that.
This mix-up trips up a huge number of new business owners, and it’s an expensive one to get wrong. Below is exactly what each registration does, what it doesn’t do, and how to decide which one (or both) your business needs.
What Is an Ontario Trade Name, Exactly?
An Ontario trade name is the name you register with the province under the Business Names Act when you operate as a sole proprietorship, partnership, or when a corporation does business under a name other than its legal corporate name. It’s an administrative registration, not a legal monopoly.
Think of it this way: registering a trade name tells Ontario’s government (and anyone who searches the public registry) who is legally responsible for a business operating under that name. It does not stop another business — even a direct competitor two blocks away — from using the same or a confusingly similar name, as long as they’ve registered it separately.
What a trade name registration actually gives you:
- Legal permission to operate, invoice, and open a bank account under that name
- A public record linking the name to a real person or corporation
- Compliance with Ontario’s Business Names Act (required if you’re not using your own legal name)
What it does NOT give you:
- Exclusive rights to the name anywhere in Canada
- The ability to stop someone else from using it
- Any protection for your logo, slogan, or brand identity
What Is a Trademark, and How Is It Different?
A trademark is a form of intellectual property registered federally through the Canadian Intellectual Property Office (CIPO) under the Trademarks Act. It protects the word, logo, sound, or combination used to identify your goods or services and legally distinguish them from everyone else’s — across the entire country, not just Ontario.
Once registered, a Canadian trademark gives you the exclusive right to use that mark nationally for the goods or services you registered it under, and the legal standing to sue for infringement if someone else uses a confusingly similar mark. That’s the core distinction: a trade name registration is about administrative compliance, while a trademark registration is about ownership and enforcement rights.

How Do You Register a Trade Name in Ontario?
Registering an Ontario trade name is done through the Ontario Business Registry, the province’s online portal that replaced the older ServiceOntario paper-based system. Here’s the process from start to finish:
- Search the Ontario Business Names Registry to confirm your proposed name isn’t identical to an existing registration in the same jurisdiction. This search does not check trademark databases — a clean result here says nothing about federal trademark conflicts.
- Decide your business structure — sole proprietorship, general partnership, or a corporation registering an operating/trade name.
- Create or log in to your Ontario Business Registry account using a ONe-key ID.
- Complete the registration form, including the business address, the names of owners/partners, and the North American Industry Classification System (NAICS) code that best describes your activity.
- Pay the registration fee — currently around $60 CAD for online registration.
- Receive your Master Business Licence (MBL), which confirms the registration and is typically required by banks to open a business account.
In my experience helping clients through this at Biz Ontario, the single most common error isn’t the registration itself — it’s assuming the name search step means the name is “theirs.” A clean trade name search only checks for exact or near-exact duplicates in the provincial registry; it says nothing about whether a company in Vancouver already holds a registered trademark on that same name nationally.
If you’d rather not navigate the Ontario Business Registry yourself, you can register your trade name through a trusted service provider like Biz Ontario. Biz Ontario has helped more than 5,000 business owners register their businesses across Canada, walking clients through the name search, structure decisions, and NAICS code selection so the registration is done correctly the first time — which matters, since errors at this stage are what typically cause delays or rejected filings.
Where Do You Check the Ontario Trade Name Registry?
The Ontario trade name registry is searchable directly through the Ontario Business Registry at ontario.ca, or through a Business Name Search on ServiceOntario’s Companies and Personal Property Security Branch records. Most incorporation service providers, including Biz Ontario and Online Business Registry offering, also pull from this same underlying provincial database.
It’s worth noting this registry only covers Ontario. If you plan to operate or sell in other provinces, you’ll need to check each provincial registry separately, or search the federal NUANS (Newly Upgraded Automated Name Search) database if you’re incorporating federally.
When Does an Ontario Trade Name Need to Be Renewed?
Ontario trade name registrations are valid for five years from the date of registration. Ontario sends a renewal reminder notice before expiry, but the legal responsibility to renew sits with the business owner, not the province.
If a trade name renewal lapses:
- The registration becomes inactive, and technically your business is no longer in compliance with the Business Names Act
- Someone else could register the identical name in the interim
- Banks and vendors that periodically verify your MBL may flag the account
Renewal is done through the same Ontario Business Registry portal, and as of the current fee schedule costs roughly the same as the original registration fee.
Do You Need Both a Trade Name and a Trademark?
For most small Ontario businesses, a trade name registration is the mandatory minimum — it’s a legal requirement to operate under a name that isn’t your own. A trademark is optional but strategic, and becomes worth the investment once your brand has real value to protect.
Consider registering a trademark when:
- You’re building a brand you plan to franchise, license, or scale beyond Ontario
- Your logo, product name, or tagline is a genuine differentiator in a competitive market
- You’ve had a direct experience — or seen a competitor experience — a copycat using a similar name in another province
- You’re investing significant marketing spend and want legal recourse if someone free-rides on your brand recognition
A trade name alone is usually sufficient when:
- You’re a local service provider (a plumber, consultant, small retailer) with no near-term plans to expand nationally
- Your business identity isn’t central to your competitive advantage
- Budget is tight and the immediate priority is legal compliance to open a bank account and start invoicing
One thing I tell every client at Biz Ontario: registering a trade name gives you a false sense of security. I’ve seen business owners spend two years building a customer base under a name, only to receive a cease-and-desist letter because a company in another province held the federal trademark the entire time. The trade name registration didn’t protect them from that — it never could.
How Does Business Name Registration Interact With Incorporation?
If you incorporate in Ontario, your corporation automatically gets a legal corporate name (which can end in Inc., Ltd., or Corp.). If you then want to operate under a different, shorter, or more marketable name — for example, “1234567 Ontario Inc.” operating as “Maple Leaf Bakery” — you still need to separately register that operating name as a trade name under the Business Names Act, even though you’re already incorporated.
This is a distinct step from Ontario business name registration for a sole proprietorship, but it uses the same Ontario Business Registry system and the same $60 CAD fee structure.
Quick Definitions Recap
- Trade name (business name): A provincial administrative record of who operates a business under a given name. No exclusivity.
- Trademark: Federal intellectual property protection giving exclusive national rights to a brand identifier.
- Legal name: Your personal name (sole proprietor) or your corporation’s registered legal name.
- NUANS report: A federal/multi-jurisdictional name search tool used mainly during incorporation, distinct from the Ontario trade name registry.
- Master Business Licence (MBL): The document ServiceOntario issues confirming your trade name registration.
Frequently Asked Questions
Does registering an Ontario trade name protect my logo?
No. A trade name registration only records the business name itself with the province. It provides no protection for logos, slogans, colours, or other visual brand elements. These may require trademark protection or, in some cases, copyright registration.
Can two businesses in Ontario have the same trade name?
The Ontario Business Registry will generally reject an identical registration within the same name search results, but slight variations can and do get through, and different business structures may register similar names. Without a trademark, there is no legal mechanism to stop a near-identical name from operating elsewhere in the province or country.
How much does it cost to register a trade name in Ontario?
Online registration through the Ontario Business Registry currently costs approximately $60 CAD, with renewal at a similar rate every five years. This is separate from and less expensive than a federal trademark application, which starts at $458 CAD per class of goods or services through CIPO.
Is a trade name the same as incorporating a business?
No. Registering a trade name does not create a separate legal entity and does not offer liability protection. Incorporation creates a distinct legal entity with its own liability protection, while a trade name is simply the name under which a sole proprietor, partnership, or existing corporation operates.
What happens if I don't renew my Ontario trade name registration?
The registration lapses and your business may fall out of compliance with the Business Names Act. This can cause issues with banks or vendors that verify your Master Business Licence, and it may allow someone else to register a similar or identical name during the lapse.
