How to Legally Expunge a Competitor’s Trademark in Canada

If a competitor registers an invalid trademark, you can apply to the Federal Court of Canada to expunge it. Under Section 18 of the Trademarks Act, grounds include bad faith or lack of distinctiveness. Legal fees for this Federal Court process can easily exceed $20,000 CAD.

In the highly competitive Canadian business landscape, your brand is your most valuable asset. But what happens if a competitor aggressively registers a trademark that rightfully belongs to you, or they trademark a generic term just to bully others in the industry? Many business owners feel helpless when they receive a cease-and-desist letter based on a questionable registration, or when they try to register their own brand only to find a “trademark troll” has beaten them to it. Fortunately, Canadian law provides a powerful remedy. You can apply to have that trademark completely erased from the public record through a process known as expungement.

Unlike a simple administrative cancellation for non-use at CIPO, expunging a trademark based on its invalidity is a serious legal battle. It is governed by Section 18 of the Trademarks Act and generally requires launching an application in the Federal Court of Canada. Whether the mark was registered in bad faith or it simply causes widespread confusion, the court has the authority to strike it down. If you find yourself in this situation, finding a seasoned intellectual property lawyer from our local directory is the first and most crucial step.

Step-by-Step Process for Federal Court Expungement

Taking a competitor to the Federal Court is a formal, highly structured procedure. Whether your business operates in Ottawa, Halifax, or Calgary, the Federal Court has national jurisdiction over intellectual property matters. Here is how the process unfolds.

Step 1: Identify the Grounds for Expungement

Before filing a lawsuit, your lawyer will assess whether you have legal grounds under Section 18 of the Trademarks Act. 🔍 Common grounds include “bad faith” (e.g., an ex-employee registered your brand to extort you), “lack of distinctiveness” (the word is too generic to be owned by one person), or “prior use” (you were using the brand in Canada long before they registered it).

Step 2: File a Notice of Application

The legal process begins when your lawyer drafts and files a Notice of Application with the Federal Court registry. This document outlines exactly why the competitor’s trademark is invalid and requests an order to direct the Registrar of Trademarks to strike it from the Canadian Intellectual Property Office (CIPO) database.

Step 3: Serve the Competitor and Exchange Evidence

Once filed, the Notice must be officially served to the competitor. Both sides will then begin compiling and exchanging evidence in the form of sworn affidavits. 🗂 For example, if you claim “prior use,” you will need to submit historical sales receipts, old advertising materials, and client testimonies proving you established the brand first.

Step 4: Cross-Examinations and the Hearing

After the affidavits are submitted, the lawyers will have the opportunity to cross-examine the witnesses out of court, producing written transcripts. Finally, both parties will appear before a Federal Court judge for a hearing. The judge will review the evidence, listen to legal arguments, and issue a binding decision on whether the trademark should be expunged.

How Much Does Federal Court Expungement Cost?

Litigating in the Federal Court is a major financial commitment. Costs can escalate depending on how aggressively the competitor defends the trademark.

  • Filing Fees: The base Federal Court filing fees are very low, often under $150 CAD.
  • Legal Fees: The true cost lies in professional legal representation. A fully contested expungement hearing can easily cost between $20,000 and $50,000 CAD.
  • Cost Awards: Keep in mind that in Canada, the “loser pays” principle generally applies. If you win your expungement case, the judge will likely order the competitor to reimburse a portion of your legal fees.

How Long Does the Process Take?

Federal Court proceedings are not swift. From the moment the Notice of Application is filed, setting a timetable for evidence and cross-examinations takes time. Generally, a straightforward expungement application will take between 12 to 18 months to reach a hearing. ⏳ If the case is highly complex, involves massive amounts of historical evidence, or is appealed, the battle can easily stretch to 2 to 3 years.

Frequently Asked Questions (FAQ)

What is the difference between Section 18 and Section 45?

Section 45 is a cheaper, administrative process at CIPO strictly for cancelling marks that haven’t been used in three years. Section 18 is a Federal Court procedure used to invalidate a trademark for deeper legal reasons, like bad faith or confusion.

Can I represent myself in Federal Court?

If you operate as a sole proprietor, you technically can represent yourself. However, if your business is incorporated, the Federal Court Rules generally require a corporation to be represented by a licensed lawyer. Due to the complex rules of evidence, DIY litigation is highly discouraged.

What is considered a “bad faith” trademark registration?

Bad faith occurs when someone registers a mark primarily to harm a competitor, extort money, or block a legitimate business from expanding, knowing they have no genuine right to use the brand themselves.

Will CIPO refund my fees if I win the case?

No. CIPO does not refund trademark application fees or Federal Court filing fees. However, the Federal Court judge has the power to order the losing competitor to reimburse you for a portion of your legal expenses.

Can I stop a competitor from using the mark while we are in court?

You can ask the court for an “interlocutory injunction” to stop them temporarily. However, these are extremely difficult and expensive to win, as you must prove you will suffer “irreparable harm” if they aren’t stopped immediately.
