Real Scenarios
1
Likelihood of Confusion
The central test for trademark infringement is whether consumers are likely to be confused about the source of goods or services. Courts consider the similarity of marks, the relatedness of goods, the channels of trade, and the sophistication of buyers.
Prompt:
“What factors do courts weigh when assessing likelihood of confusion between trademarks?”
Casey returns decisions applying the statutory confusion factors, how courts evaluated the degree of resemblance between marks, the importance of overlapping trade channels, and when confusion was found despite differences in the marks.
2
Passing Off Claims
Passing off protects unregistered marks and trade dress. A claimant must prove goodwill in the mark, misrepresentation by the defendant, and actual or potential damage. This common law action remains important even alongside statutory trademark protection.
Prompt:
“What evidence is needed to prove passing off for an unregistered trademark?”
Casey surfaces rulings on the three elements of passing off, how courts measured goodwill through sales and advertising evidence, what constituted actionable misrepresentation, and how damages were proven or presumed.
3
Trademark Dilution and Depreciation
Well-known marks may be protected against uses that depreciate their goodwill even without consumer confusion. Section 22 of the Trademarks Act addresses depreciation of goodwill, a remedy distinct from confusion-based infringement.
Prompt:
“How have courts applied the depreciation of goodwill provision for famous trademarks?”
Casey retrieves decisions on section 22 depreciation claims, how courts determined that a mark was sufficiently well-known, what evidence established a link between the defendant's use and reduced goodwill, and how this remedy differed from confusion analysis.
4
Damages and Accounting of Profits
Successful trademark holders may recover damages for lost sales, an accounting of the infringer's profits, or both in certain circumstances. Courts require evidence connecting the infringement to the financial harm and may award punitive damages in egregious cases.
Prompt:
“What damages have courts awarded for trademark infringement in Canada?”
Casey returns decisions awarding compensatory damages, accounting of profits, and punitive damages, how courts calculated lost sales attributable to infringement, and what evidence was required to support or challenge damage claims.
5
Injunctions and Enforcement
Injunctions are the most common remedy in trademark cases, preventing continued unauthorized use. Courts apply the standard interlocutory test for interim relief and may grant permanent injunctions after trial. Enforcement against online infringers raises additional challenges.
Prompt:
“When do courts grant permanent injunctions for trademark infringement?”
Casey surfaces rulings on interim and permanent injunctions, how courts assessed irreparable harm to brand owners, what factors influenced the scope of injunctive relief, and how orders were crafted to address online and cross-border infringement.
6
Counterfeiting and Criminal Remedies
Counterfeiting involves deliberately producing or selling goods bearing a forged trademark. Beyond civil remedies, Canada imposes criminal penalties for counterfeiting. Border measures allow rights holders to request that customs authorities detain suspected counterfeit goods.
Prompt:
“What criminal penalties apply to trademark counterfeiting in Canada?”
Casey retrieves decisions on criminal trademark offences, how courts distinguished counterfeiting from ordinary infringement, what penalties were imposed, and how border enforcement measures were used to intercept counterfeit goods.

Canada's Trademarks Act allows for the seizure of counterfeit goods at the border through a request to the Canada Border Services Agency — a tool that has become increasingly important as online marketplaces make cross-border counterfeiting easier.
