Trademark Litigation FAQs

What is trademark litigation and when do I need it in Canada?

Trademark litigation refers to formal legal proceedings — typically before the Federal Court of Canada — to resolve trademark disputes under the Trademarks Act. You may need a trademark litigator if someone is infringing your mark, you've received a statement of claim, or negotiations have broken down and court proceedings are the only viable path forward.

Which courts handle trademark litigation in Canada?

Trademark litigation in Canada is primarily handled by the Federal Court of Canada, which has exclusive jurisdiction over trademark infringement and passing off claims under the Trademarks Act. Provincial superior courts may also have concurrent jurisdiction in certain matters. Our lawyers are experienced Federal Court litigators with a strong track record in Canadian intellectual property disputes.

What should I do if someone is infringing my trademark?

If you believe your trademark is being infringed, it's important to act quickly. We will assess the strength of your trademark rights, issue cease and desist letters, and if necessary, pursue injunctive relief and damages through Federal Court proceedings to stop the infringing use.

What does it cost to pursue trademark litigation in Canada?

Legal fees depend on the complexity of your case and how far proceedings advance before the Federal Court of Canada. During your initial consultation, we will review the details of your dispute and provide a clear overview of our fee structure, litigation strategy, and anticipated costs. We believe in full transparency so you can make informed decisions about your matter.
