Direct answer

To register a trade name in Canada, a sole proprietor files a business name registration with the province or territory where they do business; there is no federal registry for sole proprietorships. Registration is usually required when you operate under a name other than your own. Ontario: $60source, valid 5 yearssource. Quebec: $41 ($61.50 priority)source.

What is a trade name for a business?

A trade name (also called a business name or operating name) is the name a business uses with customers when it differs from the owner's legal name. A plumber named Marie Tremblay who invoices as "Tremblay Plumbing" or "North Shore Plumbing" uses a trade name. Alberta's registry sums up when a trade name is in play: When an individual uses a name other than their own, or a corporation a name other than its legal namesource.

A sole proprietorship is the simplest way to run a business: one person, no separate legal entity. The owner earns the profits, reports them on their personal tax return and is personally responsible for the debts. Registering a trade name does not change that; it only records publicly who is behind the name.

When registration is required

Business name registration is provincial and territorial. The rule in most places is the same in substance (register if you use a name other than your own), but the wording and the deadlines differ:

  • Ontario: Required when operating under a name other than the owner's own namesource.
  • Quebec: Required within 60 days when operating under a name other than the owner's first and last namesource.
  • British Columbia: Required within 3 months of first using a business name other than one's ownsource.
  • Alberta: Trade name declaration required when using a name other than one's ownsource.
  • Saskatchewan: Not required under one's own namesource.
  • Manitoba: May not be required under one's own surnamesource.
  • New Brunswick: When carrying on business under a business namesource.
  • Nova Scotia: Required unless operating under your personal namesource.
  • Prince Edward Island: Required unless operating under your own name onlysource.
  • Newfoundland and Labrador: No provincial business name registrysource.
  • Yukon: Required if the business name differs from the owner's given namesource.
  • Northwest Territories: Required unless trading under the owner's exact legal namesource.
  • Nunavut: Required within 60 days of first using a name other than one's ownsource.

Registering a name with a province is separate from tax registration. A sole proprietor may also need a CRA business number for GST/HST once taxable sales pass the small supplier threshold ($30,000 over four consecutive calendar quarters (or in a single quarter)source), plus any municipal licence or permit for the activity.

Using a business name vs your own name

Your own legal name
  • Often no registration needed in your province
  • Nothing to renew with the registry
  • Less distinctive for marketing and online search
  • Adding words such as "Services" or "& Associates" usually turns it into a trade name
A registered trade name
  • Lets you brand the business and open a business bank account in that name
  • Must be registered, and in most provinces renewed
  • Does not give exclusive rights to the name
  • Must not suggest you are incorporated, such as by using Inc. or Ltd.
Registration is not ownership A provincial business name registration records who uses the name; it does not stop someone else from using a similar name, and it is not a trademark. Protecting a brand across Canada is done through trademark registration, which is a separate federal process.

How to register a business name in Canada

  1. 1Confirm the provinceRegister where you carry on business. Operating in more than one province can mean a registration in each.
  2. 2Check the nameSearch the provincial registry for identical or similar names. Some provinces require a name search or reservation first; Manitoba, for example, lists one at registration.
  3. 3File the registrationGive your legal name, home address, the business name, the activity and the start date. Quebec registration also produces a Quebec enterprise number (NEQ)Quebec enterprise number (NEQ)Number assigned by Quebec’s enterprise registrar on registration. Separate from the federal business number (BN).See definition →.
  4. 4Keep it currentReport changes of address or activity, and renew or file the annual update on time so the registration stays active.

What is trade name registration?

Trade name registration is the public filing that links a business name to the person or entity behind it. The registry records the name, the owner's legal name and address, the type of activity and the date the name was first used. Anyone can search the register, which is the point: customers, suppliers and courts can find out who they are dealing with. Plan for the fact that your name and address on the registration are generally publicly searchable.

Corporations use trade names too. A corporation that operates under a name other than its legal name, for example 1234567 Ontario Inc. trading as "Maple Bakery", registers that operating name in the same way. Living elsewhere does not always prevent registration. British Columbia: No B.C. residency requiredsource. Saskatchewan, for an owner who does not live in the province: Power of attorney requiredsource. The rules for the other provinces and territories are being verified.

Business Names Act and provincial rules

Each province has its own statute. In Ontario, trade name registration is governed by the Business Names Act; in Quebec, by the Act respecting the legal publicity of enterprises, under which the registration is called an immatriculation. Other provinces have a business names or partnerships registration act. These statutes generally set the same consequences: a business that operates under an unregistered name may face a fine and may have difficulty enforcing contracts in court until it registers.

Sole proprietorship or corporation: the differences

Sole proprietorship
  • No separate legal entity: you are the business
  • Unlimited personal liability for business debts
  • Profits taxed on your personal return
  • Low cost and few formalities
  • Ends with the owner; the business itself cannot be sold as shares
Corporation
  • Separate legal person that owns its assets and signs its contracts
  • Shareholders' liability generally limited to their investment
  • Files its own corporate tax return
  • Incorporation fee, annual return and a minute book
  • Can issue shares to partners and investors and be sold

Moving from one to the other is common. Incorporating does not transfer the sole proprietorship automatically: the corporation is a new entity, and the business assets, contracts and registrations are moved to it, often with an accountant's help on the tax side. Many businesses start as a sole proprietorship and incorporate when revenue, risk or the arrival of a partner makes a separate entity worthwhile. When that point comes depends on the activity and on tax factors that an accountant can assess.

Frequently asked questions

Do I need to register my sole proprietorship if I use my own name?
In most provinces, no, as long as the name is exactly your legal name with nothing added. Ontario: Required when operating under a name other than the owner's own namesource.
Can I register a trade name federally?
No. Sole proprietorships register with the province or territory where they do business. Federal registration exists for corporations, and trademarks are a separate federal process.
How much does it cost to register a business name?
It depends on the province. Ontario: $60source. Quebec: $41 ($61.50 priority)source. British Columbia: $40 (+ $30 name request)source. Incorpo's service fees are on the Pricing page.
Does a registered business name protect my brand?
No. It records who uses the name in that province; it does not give exclusive rights. Brand protection comes from a trademark registration.
Can a corporation register a trade name?
Yes. A corporation that operates under a name other than its legal name registers that operating name with the province, in the same way as a sole proprietor.
Can I open a business bank account with a registered trade name?
Banks usually ask for the registration document to open an account in the business name. Each bank sets its own requirements.
When should I incorporate instead?
There is no single threshold: liability, revenue, partners and tax all play a role. An accountant can compare both options for your activity.
