TL;DR

• Registering a company name provincially doesn’t protect your brand — trademarks are a separate federal system
• Someone can file a Canadian trademark for your business name right now, even if you’re already using it
• A trademark search takes minutes and costs nothing upfront — skipping it costs thousands later
• Check trademark availability before you spend money on branding, websites, or product packaging
• Run a Canadian trademark search on Demarka before you commit to a name

You picked a name. You Googled it. Nothing came up. You registered the business. You built the website.

Six months later, you get a letter from a lawyer saying someone else owns that name — at least as far as the Canadian trademark system is concerned.

This happens constantly. Not because founders are sloppy, but because there are several different “is this name taken” checks, and most people only do one or two of them.

The Check Most Canadian Founders Skip

When you register a business in Canada, you’re filing with a provincial registry. That gives you the right to operate under a name in that province. It does not give you exclusive rights to the brand across Canada. Two companies in different provinces can legally operate under the same name.

Trademarks are different. They’re governed federally by the Canadian Intellectual Property Office (CIPO). A registered trademark gives you exclusive rights to use a name or logo across Canada in connection with your specific products or services — and the right to stop others from using something confusingly similar.

Here’s the problem: you can have a company registered at the provincial level and a domain bought — and still have zero trademark rights. Someone else could file a trademark for your exact name today. Their filing date would take priority over your “I’ve been using this since 2023” argument in most cases.

What Actually Happens When There’s a Conflict

The cost isn’t the lawyer’s letter. The cost is everything that follows.

You’ve spent money on a logo. A website. Product packaging. Maybe inventory with your name printed on it. A rebrand doesn’t just mean a new logo — it means replacing everything those costs went into, plus whatever SEO equity you’ve built under the name.

Canadian businesses that have rebranded after trademark disputes report costs ranging from $15,000 to well over $100,000 depending on how far along they were. The filing fee for a trademark search and application? A few hundred dollars if you do it yourself. Less than a thousand with professional help.

The math is straightforward. The behaviour isn’t.

What a Real Search Covers

A Google search and a company registry lookup aren’t trademark searches. Here’s what is:

The CIPO database — This shows registered marks and pending applications. Pending matters. An application filed three months ago isn’t registered yet, but it can still block yours if it’s granted.

Similar-sounding names — CIPO doesn’t just look for exact matches. They consider phonetic similarity, visual similarity, and whether two names create the same impression in the minds of consumers. “Brexly” and “Brexley” are similar enough to cause problems. A search that only catches exact matches misses the conflicts that actually create risk.

Common law rights — Canada recognises rights that exist outside formal registration, based on actual use. A business that’s been operating under a name for years in Ontario may have enforceable rights even without a CIPO registration — particularly in that geographic market.

Cross-industry overlap — Same name, different industry doesn’t always mean you’re safe. If consumers could reasonably think the two businesses are connected, there may be a conflict.

Running a Canadian trademark search early catches most of these issues before they cost you anything.

The Actionable Version

Here’s what to actually do, in order:

• Before you name the business: Search 3–5 shortlisted names. Eliminate the ones with existing conflicts. Choose from what’s left.
• Before you invest in branding: If you already have a name, search it now — before you pay a designer or print anything.
• Before you launch: Confirm the name is clear, then file your trademark application. You can operate during the application process.
• After you’ve been trading for a while: If you’ve never searched or filed, do it now. The risk doesn’t go away on its own.

CIPO trademark registration takes 18–24 months on average. It’s a first-to-file system. The sooner you file, the better your position.

One More Thing Worth Knowing

A lot of Canadian entrepreneurs think their prior use protects them. “I’ve been using this name since 2020 — surely that counts for something.”

Sometimes it does. Common law rights are real. But proving them in a dispute is expensive and uncertain. A trademark registration is a clean, enforceable record of ownership. Prior use arguments are litigation.

Your brand is one of the few business assets that compounds over time. The more recognisable it becomes, the more valuable it is — and the more attractive it becomes to anyone who wants to file for it before you do.

Check it early. File when it’s clear. Don’t leave it until you have a problem.

Demarka is an AI-powered trademark screening tool. It helps founders quickly check whether a name is available before committing to it. It’s not a substitute for a trademark attorney — but it’s the right first step.
