Every business must have a distinct name that legally identifies itself. A business may operate under multiple names, but not all names serve the same purpose. In Canada, it’s important to understand the differences between a corporate name, a trade name, and a trademark —especially when launching or expanding your business.
Corporate Name: Your Legal Identity
A corporate name is the legal name of your corporation and must be used in contracts and invoices. It can take one of two forms:
- Numbered name: Assigned by the government (for example, 1234567 Canada Inc.), this format includes your corporation number, jurisdiction (such as Canada or Ontario), and a legal suffix like Inc., Ltd., or Corp. If your business does not interact with customers directly or you prefer to maintain a low profile, a numbered name may be perfectly suitable. In fact, many holding companies and special purpose companies use numbered names.
- Word name: A custom name chosen during incorporation (for example, Maple Tech Solutions Inc.). In some provinces like Ontario, you must run a NUANS search to check for name conflicts. Federally, this search is integrated into the incorporation process.
Business Name: Your Public-Facing Brand
If you incorporate under a numbered name but want a more memorable identity, you can register a trade name or business name with the province where you operate. This is the name customers see on storefronts, websites, and marketing materials.
However, you should be mindful that:
- Business name registration does not grant exclusivity. Other businesses may register the same or similar name, which could lead to legal disputes.
- Business names expire and are subject to renewal. In Ontario, they expire every five years. Corporate names do not expire.
- Business names must be registered separately in each province or territory where you do business.
Trademark: Your Brand Protection
A trademark protects the unique identity of your products or services. Unlike corporate or trade names, trademarks help customers recognize and distinguish your offerings in the marketplace.
Key points to note:
- A corporate or trade name does not automatically qualify as a trademark.
- Trademarks must be distinctive and non-descriptive.
- Registration is optional but provides stronger legal protection.
- Trademarks are examined and registered by the Canadian Intellectual Property Office (CIPO).
Final Tips
Before choosing a name for your business, consider the following steps:
- Run a NUANS search to check for similar corporate names.
- Search the CIPO’s trademark database to avoid potential trademark disputes.
- Choose a name that is memorable, brand-worthy, compliant with naming requirements.
A thoughtful naming strategy helps protect your business and build lasting recognition. It’s worth taking the time to get it right.
