Registering a Defensive Trademark in Canada: Is It Legal?

7 Jul 2026 5 min read No comments Copyright, Trademark & Patents Canada
💡

Generally, filing a trademark purely to block competitors without intending to use it is highly risky in Canada. Under the Trademarks Act, a mark must be actively used in commerce, otherwise it can be cancelled after three years. Filing a basic application at the Canadian Intellectual Property Office (CIPO) currently costs $491.06 CAD.

Canada boasts incredibly vibrant business hubs, from bustling tech sectors in Toronto to heavy industry in Calgary. 🏢 When launching a new company, some entrepreneurs attempt to file multiple trademark applications for brand names they never actually intend to use. This strategy, known as “defensive trademarking” or “trademark squatting,” is designed purely to block competitors from entering the market or using specific product names.

While the Canadian Intellectual Property Office (CIPO) allows you to file an application before you officially launch a product, hoarding trademarks is not a viable long-term legal strategy. The foundation of Canadian trademark law is built on “use.” If you simply register a name and let it sit dormant, the law provides a very straightforward mechanism for your competitors to legally strip that trademark away from you, rendering your defensive investment completely worthless.

Step-by-Step Process in Canada

Whether your business operates in Vancouver or Halifax, the rules surrounding trademark registration and enforcement are federal. 📋 If you are considering registering a brand name, you must follow the proper legal steps to ensure your intellectual property rights are genuine and defensible.

Step 1: Conducting a CIPO Database Search

Before filing anything, your trademark agent will search the CIPO database to ensure the name is not already registered or confusingly similar to an existing Canadian brand. This step is critical, as filing a defensive trademark that accidentally infringes on an active business can result in immediate cease-and-desist letters and costly litigation.

Step 2: Filing the Application with Genuine Intent

When you file your application, you must list the exact goods and services you plan to offer. 📝 While Canada removed the requirement to file a “Declaration of Use” prior to registration, the law still requires you to have a genuine intent to use the mark in Canadian commerce. Filing a massive list of completely unrelated goods just to block others is strongly discouraged.

Step 3: Proving Use in Commerce

Once your trademark is officially registered, the clock starts ticking. To maintain your legal rights, you must actively use the trademark in the normal course of trade. This means selling products bearing the logo, advertising services in Canada, and generating real commercial activity. Printing one fake invoice to a friend does not satisfy the legal definition of use.

Step 4: Surviving a Section 45 Non-Use Proceeding

The greatest risk of a defensive trademark occurs on the third anniversary of its registration. 🚨 Under Section 45 of the Trademarks Act, any person or competitor can pay a fee to CIPO and request that your trademark be expunged (cancelled) for non-use. If challenged, you must provide sworn affidavits and strict physical evidence proving you have sold goods or services under that name in the past three years. If you cannot, you lose the trademark.

How Much Does it Cost in Canada?

Securing and defending a trademark requires a financial commitment. If you are filing defensively, you risk losing these non-refundable expenses:

  • CIPO Filing Fees: The basic government fee to file an application online in the first class of goods or services is $491.06 CAD. Each additional class costs an extra $149.04 CAD.
  • Trademark Agent Fees: Hiring an experienced Canadian intellectual property lawyer or registered agent to draft and file the application typically costs between $1,000 and $2,500 CAD.
  • Section 45 Defence Costs: If a competitor challenges your dormant trademark, paying a law firm to draft affidavits and fight the expungement proceeding can easily cost $5,000 to $10,000 CAD.

Ultimately, paying thousands of dollars to register and defend a brand name you do not use is a poor allocation of corporate capital.

How Long Does the Process Take?

The Canadian trademark system has become significantly more efficient. ⏱ A standard trademark application currently takes approximately 8 months from the date of filing to be reviewed by an examiner. Once registered, the trademark is protected for 10 years, but it becomes legally vulnerable to a Section 45 cancellation proceeding exactly 3 years after the registration date.

Frequently Asked Questions (FAQ)

Does CIPO automatically cancel trademarks if I stop using them?

No, CIPO does not actively monitor the marketplace to see if you are using your trademark. A cancellation almost always happens because a competitor explicitly files a Section 45 proceeding requesting that CIPO investigate your non-use.

Can I register a trademark just to sell it to someone else later?

While trademark assignments (sales) are legal and common, registering a mark in bad faith solely to extort a brand owner (cybersquatting or trademark squatting) can lead to your application being successfully opposed and struck down.

What if I have a valid reason for not using the trademark?

If a competitor launches a Section 45 proceeding, you can sometimes save your trademark if you prove that “special circumstances” prevented you from using it. This is usually limited to things like sudden government regulatory bans or severe factory fires, not just a lack of business funding.

Can I stop an American company from entering Canada with a defensive mark?

If an American company already has a massive global reputation that spills over into Canada, trying to register their name here defensively is considered bad faith. They can easily file an opposition to block your application before it even registers.

Do I need a lawyer to file a trademark?

You are not legally required to have a lawyer. However, drafting the specific “classes of goods and services” requires precise legal language. Most applicants hire a registered Canadian trademark agent to ensure the application is not rejected for technical errors.
