Quebec Business Name: Search, Rules and Reservation

If you have incorporated federally or in Ontario before, you already know the drill: run a Nuans report, wait for the name to clear, then file. Quebec works differently. There is no mandatory name search, nobody screens your name against trademarks, and registering it in the enterprise register gives you no rights over it at all. Here is how to check a business name in Quebec and register one that actually holds.

How do you check if a business name is available in Quebec?

Run four checks, not one. The Quebec enterprise register tells you whether an identical name is already registered. The trademarks database tells you whether someone owns rights to it. The domain and social handles tell you whether you can use it commercially. Only the fourth step, an optional reservation, gets the Registraire to pre-validate it.

The sentence that changes everything sits in section 19 of the Act respecting the legal publicity of enterprises: no right to a name is conferred on a registrant solely by recording the name in the register. Quebec's register is a publicity tool, not a title. Meanwhile section 18 of the Business Corporations Act puts the burden squarely on you, since the persons concerned are responsible for ensuring the name complies with the law.

Does Quebec require a Nuans search?

No. Quebec is one of the provinces that does not require a name search with your application, and Corporations Canada says so directly on its own Nuans page. Alberta, New Brunswick and Ontario require one; Quebec, British Columbia, Manitoba, Saskatchewan and several others do not.

That "none" in the trademark row is the trap. When you incorporate federally, your proposed name is compared against existing corporate names, business names and trademarks before approval. In Quebec nobody runs that comparison. You can be granted a name that infringes a registered trademark and only find out when a demand letter arrives.

One current detail worth knowing: for a federal incorporation the Nuans search is now built into the online application, so you should not order a standalone report beforehand. Standalone reports remain required for revivals, amalgamations and continuances.

What are the rules for naming a business in Quebec?

Section 17 of the Act respecting the legal publicity of enterprises lists nine prohibitions. Breaking a single one is enough to get your name refused.

A compliant Quebec name has up to three parts: a generic element describing the activity, which must be in French, a specific element that distinguishes you, and a particle stating the legal form. In Quincaillerie Saint-Jean inc., "Quincaillerie" is the generic, "Saint-Jean" is the specific and "inc." is the particle.

The specific element is what makes a name defensible. A purely descriptive name distinguishes nothing, which is the same standard Corporations Canada applies when it says "Car Manufacturer Inc." lacks distinctiveness. Symbols cannot replace letters either.

What about the French-language requirements?

Section 63 of the Charter of the French language requires an enterprise name to be in French, and section 64 makes a French name a condition of obtaining juridical personality in Quebec. An expression from another language may serve as the specific element provided it is used with a French generic term.

Signage is a separate regime enforced by the OQLF, not by the Registraire, and it tightened on June 1, 2025. A trademark may now appear only in another language on signage visible from outside premises if it is registered under the Trademarks Act, where the previous rule accepted a merely recognized mark. French must also be markedly predominant, which now means the French text occupies at least twice the space in the same visual field, and a non-French mark on exterior signage must be accompanied by French wording such as a generic term, a description or a slogan.

Plenty of articles written in 2024 still describe the old rule. If your brand carries an English trademark and you have a storefront in Quebec, this is the paragraph that matters most to you.

Should you use a numbered company instead?

A numbered company is the fast lane. The Registraire assigns a designating number such as 1234-5678 Québec inc., and because you requested a number, you are not required to file the declaration stating that reasonable means were taken to verify the name's compliance.

It suits a holding company, a corporation created under time pressure, or a founder whose commercial brand is not settled. There is no separate fee: the designating number comes with the certificate of constitution at about $397, and you simply skip the $27 reservation. If you later trade under a commercial name, you must declare that name in the register.

What is a trade name, and when do you declare it?

In Quebec it is called an "other name used in Québec", and an assumed name in everyday speech. The trigger is use: as soon as your enterprise uses it or is about to, it must be declared; once you stop using it, it must be removed. You can hold several at once, and declaring one costs nothing through a current updating declaration.

Two rules catch people out. Under section 21 of the Business Corporations Act, a corporation's trade name cannot contain "compagnie", "s.a.", "ltée" or "inc." And if your constituting documents contain no French version of your name, the French version you use in Quebec must be declared here. Our guide to registration and legal publicity covers the rest of the filings.

What if another business uses a similar name?

The Registraire will not act on confusion by itself. Its own-initiative power covers only the first six prohibitions, so a confusingly similar name is something an interested person must challenge, at a cost of about $660 for the administrative recourse.

The analysis weighs the distinctiveness of each name, visual and phonetic similarity, the ideas each conveys, how each is used, then reputation, actual competition and the territories served. The decision takes effect 30 days after notification unless contested before the Administrative Tribunal of Québec.

If the conflict is with a trademark rather than a registered name, the Registraire has no role at all. That is a Trademarks Act matter, which is exactly why the free CIPO search belongs in your four checks and why an NDA and a proper document set are not substitutes for owning your brand.

Fees and legal provisions reflect the rules in force in August 2026 and the fee schedule updated January 1, 2026. Confirm current amounts before filing.

Frequently asked questions about Quebec business names

How much does it cost to register a business name in Quebec? A sole proprietorship's declaration of registration costs about $41, and a corporation's certificate of constitution about $397. Adding a trade name through a current updating declaration is free. An optional name reservation costs about $27 for 90 days.

Does registering my name in Quebec protect it? No. Section 19 of the Act respecting the legal publicity of enterprises states that recording a name in the register confers no right to it. Only a trademark registered with CIPO gives you rights you can enforce elsewhere in Canada.

Can I use an English-only business name in Quebec? Not as the name declared in the register, which must be in French. An expression from another language can serve as the distinguishing element alongside a French generic term, and an English version may be declared in parallel.

Do I need a Nuans report for a Quebec corporation? No. Quebec does not require a name search with your application. That also means no one screens your name against trademarks, so running the free CIPO database search yourself is strongly advised before you commit to a brand.

What is the benefit of a numbered company? Speed and certainty. You skip the name compliance analysis and the risk of refusal entirely, at no extra cost. The trade-off is a name with no marketing value, so most founders later declare a commercial trade name in the register.

Get your name cleared before you file

A refused name means a delayed incorporation and sometimes fees paid twice. A name that clears but infringes a trademark is worse, because you build a brand on ground that is not yours.
