How to Register a Company Name in Canada: A Step-by-Step Guide

Before you launch your business, you’ll have to go through one of the most fun and infuriating challenges: giving your business an official name. While there’s no exact science to coming up with a great company name, keep in mind that it does more than just appear on invoices and signage. It protects business identity, establishes legal recognition, and builds trust with customers.

Once you’ve come up with something you love, registering your company name is a crucial step toward compliance. Without it, you can’t open a business bank account, apply for permits, or access tax accounts. Your business name and business number (BN) also work hand in hand: the name defines your brand, while the BN connects you to government services like GST/HST, payroll, and import/export.

This guide will walk you through the process of registering your company name in Canada, including selecting a distinct name, conducting a NUANS search, determining whether to register at the federal or provincial level, and submitting your application.

Key Takeaways

• Registering your company name is essential for compliance, credibility, and building a trusted brand.
• NUANS searches are required only for incorporations, not for sole proprietorships or partnerships.
• Federal registration provides legal nationwide protection, while provincial registration is simpler for local businesses.

Step 1. Choose a Unique and Distinct Name

Your business name must be unique to prevent name conflicts with other businesses. When brainstorming, consider names that are creative yet professional. Ask yourself:

• Does it reflect what my business offers?
• Could it grow with me as I expand?
• Is it easy to spell and remember?

Pick a name people won’t forget. It’ll help you stand out now and make it easier to protect your brand with a trademark later.

Step 2. Conduct a Name Search or NUANS Report

Once you’ve shortlisted names, you’ll need to verify if they’re available. This involves checking name availability through databases like:

• The Nuans® (Newly Upgraded Automated Name Search) system is required for federal incorporations and provinces such as Ontario, Alberta, New Brunswick, and PEI.
• Provincial registries like the Ontario Business Registry or BC’s name request service.
• Trademark searches through the Canadian Intellectual Property Office (CIPO).
• Domain name registries (for securing your .ca or .com).

Important: A NUANS report lists existing corporate names and trademarks similar to your proposed name. It highlights exact matches (which will block approval) and near-matches that might cause confusion. This report is valid for 90 days only and must meet legal guidelines before submission.

If your name is rejected, you can modify it by adding distinctive descriptors (e.g., location or service) and order a new NUANS report.

Step 3. Decide on Federal or Provincial Registration

Where and how you register determines the scope of your name’s protection. 

• Federal Registration: Handled by Corporations Canada, it provides nationwide protection and is linked to the corporate registry at the national level. This option is best if you plan to operate in multiple provinces. However, it requires annual filings and extra-provincial registrations where you do business.
• Provincial Registration: Limits protection to one province, but it is usually faster and more cost-effective. For example, if your business operates only in Ontario, registering through the Ontario Business Registry is sufficient.

Understanding the pros and cons of incorporating a business in Canada will also help guide your decision. Federal incorporation offers stronger protection but comes with more compliance, while provincial registration suits businesses with local operations.

Step 4. Submit Name Registration Application

After choosing your jurisdiction, you’re ready to file your application. This step requires submission to the provincial authority or Corporations Canada if registering federally. View the complete list of provincial registries here.

You’ll typically need to provide:

1. Proposed company name (and NUANS report if required)
2. Business address
3. Owner identification details
4. Articles of Incorporation (for corporations)
5. Declaration of Trade Name or Partnership (for sole proprietorships/partnerships)

Double-check your details before submitting. Errors can cause delays, and fixing them often means extra time and fees. 

After your name is approved and registered, you may also need a business number (BN) from the Canada Revenue Agency (CRA). If you’re unsure, check our guide on how to get a business number in Canada so you’re set up for compliance from the start.

Step 5. Pay the Required Fees

Registration fees vary depending on your jurisdiction and structure. Check the fee details for each provincial registry here.

• Federal: $200 (online) or $250 (paper), plus NUANS ($13.80–$45)
• Ontario: $60 for a business name; up to $300 for incorporation
• British Columbia: $30 for a name request, $100–$350 for incorporation
• Alberta: Starts at $160, including name approval
• Quebec: $26–$39 for name reservation, $40–$389 for registration

Most provinces fall within the $30–$500 range. Fees are non-refundable, so ensure your documents are accurate before paying. Keep your receipt for records, as it will be essential for future business operations.

Registering a Name for Different Business Structures

Whether you’re a sole proprietor, part of a partnership, or incorporating, the process of registering a name also depends on your business structure. 

Sole Proprietorship and Partnership Name Registration

For sole proprietorships and partnerships, name registration is generally simpler. If you operate under your exact legal name (e.g., “John Smith”), no registration is required. But if you use a different business name (e.g., “John Smith Consulting”), you need to register that trade name with the government through your provincial registry.

Unlike corporations, sole proprietorships and partnerships do not require a NUANS report, since NUANS searches are only required for incorporations. Instead, you simply file your trade name registration with the appropriate registry.

Corporation Name Registration

Corporations face stricter naming rules than sole proprietorships or partnerships. A corporate name must include three elements:

1. Distinctive (something unique to your business)
2. Descriptive (what the business does)
3. Legal ending (e.g., Ltd., Inc., Corp.)

If you choose a named corporation, you’ll need to complete a NUANS search, and a report must be submitted along with the Articles of Incorporation. This step ensures the name is distinct and avoids conflicts with existing corporations or trademarks.

Alternatively, you can register a numbered corporation (e.g., “1234567 Canada Inc.”). Numbered corporations don’t require a NUANS search because the number itself provides uniqueness.

Operating Under a Trade Name (Doing Business As)

A trade name, also known as “Doing Business As” (DBA), is an operating name that’s different from your legal business name. For example, a corporation registered as “1234567 Canada Inc.” may also operate as “Bright Path Consulting.”

Even if you’ve already incorporated, you must register a trade name with the provincial or territorial registry if you plan to use it publicly on signage, contracts, or marketing materials. This also doesn’t require a NUANS report, since the registration is tied to your existing legal entity.

What are the Different Types of Business Names?

In Canada, businesses can operate under different types of names, each serving a different role in compliance and branding. Here’s how they compare.
