How to Trademark a Business Name in Canada: Step-by-Step

If you've asked "how do I trademark my business name in Canada," the short answer is: you file an application with the Canadian Intellectual Property Office (CIPO) after confirming your name is available and correctly classified. The longer answer — the part that actually determines whether your application gets approved — is everything that happens before and after that filing.

Here's the process in the order it actually happens, from a company that files these every week.

Step 1: Run a clearance search first

Before you file anything, you need to know whether your name is already taken — or close enough to an existing mark that CIPO will reject your application on confusion grounds. A proper clearance search checks the CIPO trademark database, common law (unregistered) marks in use across Canada, and often U.S. and international registers if you plan to expand.

Skipping this step is the single most common reason DIY trademark applications get rejected. CIPO's own database search only shows exact and near-exact matches — it won't catch a confusingly similar mark in a different spelling or a related industry. Professional filers use commercial-grade tools like Corsearch to catch conflicts a basic database search misses.

Step 2: Determine your Nice Classification

Canadian trademarks are filed under the Nice Classification system — 45 international categories of goods and services. Your trademark only protects the classes you file under, not your business generally. A coffee shop filing only under "retail sale of coffee" gets no protection if they later launch a packaged product line under a different class.

Most businesses should file under every class that covers their current operations and any direction they're realistically likely to grow into within the next few years, since Canada is a first-to-file jurisdiction — the earlier you claim a class, the cheaper it is to defend later.

Step 3: Draft your goods & services descriptions

Each class requires a written description of exactly what goods or services you're claiming. Vague or overly broad descriptions get flagged by CIPO examiners and can add months to your timeline through amendment requests. Precise, correctly scoped language is what separates a smooth filing from one that bounces back with an Examiner's Report.

Step 4: File the complete application with CIPO

Once your search is clean and your classes and descriptions are set, the application is submitted through CIPO's online portal. This includes applicant details, the mark itself (word mark, design mark, or both), the classes, and the government filing fee.

Step 5: Your priority date locks in immediately

This is the part most business owners don't realize: your trademark rights and priority date are established the moment you file — not the moment CIPO approves the application. Full examination takes roughly 18–24 months, but you're protected from day one of filing. This is exactly why filing early matters, even though the wait for approval is long.

Step 6: Respond to any Examiner's Report

CIPO may come back with questions or requested amendments before final approval — this is normal and doesn't mean your application failed. You'll have a set window to respond. (We cover this in detail in our Examiner's Report guide.)

Step 7: Registration and renewal

Once approved, your trademark is registered for 10 years and renewable indefinitely. Set a reminder well before the renewal deadline — a lapsed trademark loses its protection and can be claimed by someone else.

Can I file a Canadian trademark myself?

Yes — CIPO's portal is open to anyone. The tradeoff is risk: incomplete clearance searches, incorrect classification, and poorly drafted descriptions are the leading causes of rejected or narrowly-protected applications, and the government fee is non-refundable regardless of outcome.
