10 Things to Know About Passing Off and Unfair Competition in Canada

Businesses of every size invest substantial time and money into developing their brand, trade names, and goodwill. Whether it’s a distinctive logo, a well-recognized label, a slogan that resonates with customers, or even a unique style of packaging, these assets help a business establish its identity and build a loyal consumer base. When others attempt to imitate or capitalize on this reputation—confusing the public in the process—the law of passing off and unfair competition in Canada comes into play.

Introduction

Businesses of every size invest substantial time and money into developing their brand, trade names, and goodwill. Whether it’s a distinctive logo, a well-recognized label, a slogan that resonates with customers, or even a unique style of packaging, these assets help a business establish its identity and build a loyal consumer base. When others attempt to imitate or capitalize on this reputation—confusing the public in the process—the law of passing off and unfair competition in Canada comes into play.

Although they are often discussed together, passing off and unfair competition each have distinct legal elements and remedies. A passing off claim typically arises when one business misrepresents its goods or services as those of another—thus misleading the public and damaging the rightful business’s goodwill. Unfair competition, a broader concept, can encompass a wide spectrum of deceptive or unethical business practices meant to mislead consumers or sabotage competitors.

If you operate in a competitive market and suspect another business is infringing your hard-earned brand reputation, it’s essential to understand your options. Likewise, if you are expanding your product line or rebranding, it pays to know the legal limits so you can avoid landing in hot water. Below, you’ll find a detailed look at 10 key insights about passing off and unfair competition in Canada, from what these concepts entail to how you can seek or defend legal remedies. We’re a Toronto-based firm dedicated to safeguarding clients’ market identity and fair competition rights.

1. The Legal Foundations of Passing Off

Passing off is deeply rooted in common law principles that safeguard goodwill in a brand, product, or service. Before the introduction of modern trademark legislation, passing off was one of the primary ways businesses protected their unique market identity. Even now, when trademarks are governed by the federal Trademarks Act, passing off remains a robust and independent cause of action.

A successful passing off claim usually requires proving three core elements:

  1. Goodwill – The plaintiff must demonstrate that their product, service, or mark enjoys a certain level of recognition or reputation in the marketplace.

  2. Misrepresentation – The defendant’s conduct must be likely to cause confusion about the source or identity of goods or services; it need not be deliberate, but it must have the effect of misleading the public.

  3. Damage – The plaintiff must show they suffered—or are likely to suffer—damage as a result of the misrepresentation, such as lost sales or harm to their brand’s reputation.


Ontario courts, as well as courts across Canada, assess these criteria flexibly, taking into account how an average consumer might be misled. If you believe another business is using a name, logo, or branding too similar to yours, it’s often advisable to seek legal counsel promptly to protect your interests.

2. Unfair Competition: Beyond Passing Off

While passing off is a well-known tort, unfair competition is a broader concept that can encompass various deceptive or unethical business practices. In Canada, the Competition Act sets out some provisions against misleading representations. However, the phrase “unfair competition” in the commercial litigation context is often used to describe a range of actions that hamper fair marketplace activity. These can include:

  • Misappropriation of trade secrets

  • False or misleading advertising

  • Trademark infringement

  • Cyber-squatting or domain name hijacking

  • “Ambush marketing” aimed at associating a product with a competitor’s event or brand


Sometimes, “unfair competition” is used as a catch-all term to capture commercial activities that are not necessarily passing off but still harm a rival through unethical means. The remedies can include damages, injunctions, and corrective advertising orders. Businesses in highly competitive industries (e.g., technology, consumer goods) should be vigilant about any conduct that could be construed as unfair competition—both to avoid potential liability and to protect themselves from unscrupulous competitors.

3. The Intersection of Trademarks and Passing Off

One of the most common contexts for passing off claims arises when businesses have not registered a trademark under the Trademarks Act or are waiting for registration to be completed. A trademark (like a brand name or logo) can be protected under both statutory and common law. Owners of a registered trademark enjoy the advantage of a presumption of validity and nationwide protection, whereas owners of an unregistered mark must rely on the common law action for passing off in their particular geographical area of reputation.

Even if a business has an unregistered mark, the key is proving that the public has come to associate that mark with its goods or services. If a competitor’s mark is confusingly similar and is likely to lead consumers to mistakenly believe they are buying your goods or services, a passing off claim may be successful. This makes the passing off action a powerful tool for protecting unregistered marks—though the burden of proof is somewhat higher than for a registered trademark owner, who can simply assert infringement under the Trademarks Act.

Trademarks and passing off claims often go hand in hand. If your competitor is infringing on a trademark that you have registered, you might be able to bring a dual claim of infringement under the Trademarks Act and passing off under common law. This approach can bolster your chances of securing an injunction or damages award, as the separate legal avenues reinforce the seriousness of the infringement.

4. Goodwill and Reputation: The Heart of Passing Off

Goodwill is the intangible yet highly valuable asset tied to a brand’s reputation. Courts often focus on whether the plaintiff has established goodwill in a particular market or with a certain group of consumers. This can be demonstrated by factors such as:

  • Length of Use: How long the brand or mark has been in use.

  • Geographic Scope: Where the goods or services have been sold or marketed.

  • Advertising and Marketing: The scale and nature of promotional activities.

  • Sales Data: Evidence of commercial success linked to the mark or brand.

  • Consumer Recognition: Testimonials, surveys, or media references that show customers specifically associate the mark with the plaintiff.


Once goodwill is established, any misrepresentation by a competitor that creates confusion can give rise to a passing off action, if damages or the likelihood of damage can be shown. Many Ontario-based companies invest heavily in establishing their brands regionally—For clients needing guidance on deceptive business practices, our commercial litigators in Toronto can help.

5. Likelihood of Confusion: The Keystone of Misrepresentation

In a passing off or unfair competition case, courts examine whether the defendant’s branding, packaging, or advertising is likely to cause confusion among the general public. The test is not whether the plaintiff’s loyal fans would be fooled, but whether a typical consumer, somewhat in a hurry and with imperfect recollection, might mistake the two offerings. Important considerations include:

  • Overall Impression: Courts look beyond side-by-side comparisons and assess how the marks appear in real-world contexts.

  • Nature of the Goods or Services: Similarity in product lines or industries can heighten confusion.

  • Customer Base: Even if both parties’ products differ, confusion might still arise if they target similar demographics.

  • Visual and Phonetic Similarities: Logos, trade dress, and brand names can mislead consumers if they look or sound alike.

  • Geographic Overlap: Local or regional factors play a part in how confusion arises for the average customer.


Establishing confusion is often the crux of the claim. The more evidence you have (e.g., customer inquiries, mistaken social media mentions, or market surveys) demonstrating actual confusion, the stronger your passing off or unfair competition case becomes.

6. Damages and Other Remedies

When facing a passing off or unfair competition dispute, businesses often concentrate on obtaining immediate relief—usually an injunction to stop the damaging conduct. However, damages are also a crucial component. Courts in Ontario can award compensatory damages to reflect the business losses and reputational harm caused by the misrepresentation. In egregious cases, punitive damages may be granted if the defendant’s conduct is especially reckless or malicious.

Other common remedies include:

  • Accounting of Profits: The defendant must turn over any profits made through the wrongful use of the plaintiff’s goodwill.

  • Delivery Up: The defendant may have to surrender infringing products, advertising materials, or other items that mislead the public.

  • Corrective Advertising: In some situations, courts order statements that clarify the true source of a product or service.


Compared to standard breach-of-contract disputes, a passing off or unfair competition lawsuit can be more complex to quantify because it’s not always easy to measure lost goodwill.

7. The Role of the Competition Act in Unfair Competition

Many people assume the Competition Act applies only to large-scale antitrust issues such as price-fixing or mergers. However, the Act also contains provisions on deceptive marketing practices, which prohibit false or misleading representations to the public. Although individuals and businesses typically bring passing off claims through civil courts, the Competition Act can be leveraged by regulators like the Competition Bureau in cases where the conduct at issue is widespread, harmful to consumers, or intentionally deceptive.

For example, a business engaging in false advertising about its competitor’s products or intentionally sowing confusion in the marketplace could face investigations or proceedings under the Competition Act. The penalties include administrative monetary penalties, injunctions, and orders to publish corrective notices. While private citizens cannot directly bring a cause of action under the Competition Act in most cases, they can file a complaint with the Competition Bureau, which can decide to investigate.

Unfair competition claims sometimes go hand in hand with allegations of Competition Act breaches, especially if the offending conduct includes misrepresentations that harm not only one competitor but also the public at large. If your competitor is marketing in a way that seriously misleads customers—perhaps about product quality, origin, or price—consulting a lawyer who understands both passing off and the Competition Act can be instrumental in crafting a comprehensive legal strategy.

8. Online Passing Off and Domain Disputes

In today’s digital age, much of the brand identity and goodwill a company creates moves online—through websites, social media, and e-commerce platforms. As a result, online passing off has become a significant concern. Common situations include domain name “squatting,” where a third party registers a domain name nearly identical to a known brand, or uses meta tags and keywords that mimic another business’s trademarks. These tactics can divert online traffic, harm a brand’s SEO standing, and confuse consumers about who is truly behind a given website or product listing.

Canada offers specific domain resolution processes, such as the Canadian Internet Registration Authority (CIRA) Dispute Resolution Policy for .ca domains, which can be a quicker alternative to litigation if you meet certain criteria. For other domains (like .com or .net), the Uniform Domain-Name Dispute-Resolution Policy (UDRP) might apply. Although these policies don’t always allow for monetary damages, they often enable brand owners to gain control of a misleading domain name more rapidly than through the court system.

Nevertheless, domain disputes often go hand in hand with formal passing off or trademark infringement claims in court. If the defendant’s domain usage aligns with other forms of misrepresentation, seeking an injunction through traditional legal channels may be warranted. Because online brand protection is vital for businesses of all sizes, working with local Toronto commercial litigation lawyers experienced in digital disputes is crucial when you encounter suspicious websites or domain name conflicts.

9. Defending Against Passing Off and Unfair Competition Claims

Not every similarity or competitive manoeuvre automatically amounts to passing off or unfair competition. If your business is accused of these practices, there are various defences you might raise:

  • No Likelihood of Confusion: Arguing that differences in branding, packaging, or market positioning are sufficient to avoid consumer confusion.

  • Descriptive Fair Use: Demonstrating that the words or symbols used are merely descriptive or generic, not pointing specifically to the plaintiff’s brand identity.

  • Concurrent Use and Honest Practices: In some rare instances, you might show that two businesses have used similar marks independently in different geographic areas without confusion.

  • Laches or Delay: If the plaintiff waited an unreasonable time to bring the claim, you might raise a defence that they tacitly accepted the alleged infringement.


A robust defence often requires market surveys, expert testimony on consumer perceptions, and thorough documentation of your branding process. If a case does go to court, your counsel might also challenge the plaintiff’s evidence of goodwill or actual damage. By highlighting the differences between the brands and the minimal risk of misrepresentation, you can weaken the plaintiff’s claim. Nonetheless, this area of law is nuanced, and each case turns on its specific facts.

10. Practical Tips and Proactive Measures

Proactive steps can mitigate risks related to passing off and unfair competition, both from an offensive and defensive standpoint. For business owners seeking to protect their brand:

  • Register Trademarks: Although you can assert unregistered rights, having a registered trademark simplifies the legal burden for infringement claims.

  • Monitor the Market: Regularly audit online platforms, competitor listings, trade publications, and social media to detect unauthorized uses of your brand early.

  • Establish Clear Branding: Distinctive logos, colour schemes, and product packaging can reduce the risk of confusion and strengthen your goodwill in the marketplace.

  • Document Advertising Efforts: Keep detailed records of marketing campaigns, client testimonials, and sales figures to establish evidence of goodwill.


For businesses fearful of inadvertently committing passing off:

  • Conduct Thorough Searches: Before launching a new product name, domain, or logo, research existing uses to avoid similarity with established brands.

  • Obtain Professional Opinions: Engaging lawyers or trademark agents early can help gauge whether your chosen brand elements risk confusion.

  • Implement Clear Labelling: Use disclaimers or unique design elements to differentiate your offerings from any competitors’ goods.

  • Respond Promptly to Allegations: If you receive a cease-and-desist letter, consult counsel immediately rather than ignoring it. Early negotiation can prevent a protracted legal battle.


These measures are not foolproof, but they significantly reduce the likelihood of embroiling your business in a costly lawsuit—or finding yourself undefended when brand misappropriation occurs. Many Toronto-based (and Ontario-based) companies now see these steps as indispensable in safeguarding their market position.

Conclusion

In Canada’s competitive economy, passing off and unfair competition claims address a vital need: ensuring businesses operate on a level playing field and do not ride on the coattails of others’ reputations. Whether you are a plaintiff seeking to protect your established goodwill or a defendant alleged to have engaged in deceptive branding, understanding the underlying principles of passing off and unfair competition is essential. The three pillars of goodwill, misrepresentation, and damage remain the cornerstone of passing off, while unfair competition encompasses a broader range of deceptive market practices.

Although statutes like the Competition Act provide important checks against misleading advertising, common law passing off actions continue to offer a powerful tool for business owners whose trademarks may be unregistered or whose brand identity is too unique to fit neatly into statutory categories. As commerce increasingly shifts online, domain name disputes, social media misrepresentations, and other digital conflicts have added fresh dimensions to these claims—underscoring the ongoing need for up-to-date legal advice.

Wherever your brand stands on this spectrum, a strategic approach is paramount. Maintaining detailed evidence of your market presence and goodwill can be decisive in passing off litigation. Conducting thorough searches and being careful in how you position or label new products can minimize your exposure to unfair competition claims. Most importantly, if you suspect your brand is being infringed—or if you are accused of passing off—seeking prompt legal counsel can help guide you through the complexities of Canadian law.
