Should You Incorporate a Numbered Company in Ontario?

Every Ontario corporation receives a corporation number from the Director under section 8 of the Business Corporations Act, and that number appears on its certificate of incorporation whether or not it has a word name. A numbered company is simply a corporation whose articles did not specify a name. Subsection 8 (2) provides that where no name is set out in the articles delivered to the Director, the corporation is assigned a number name.

The Act defines a number name as the corporation number followed by the word Ontario and one of the legal elements required by subsection 10 (1): Limited, Incorporated or Corporation, or the abbreviations Ltd., Inc. or Corp. The result looks like 1234567 Ontario Inc. Corporations Canada assigns a comparable number name to a federal corporation that incorporates without a word name.

A numbered company is a complete corporation in every other respect. It has the same limited liability, the same directors' duties, the same filing obligations and the same ability to own property, sign contracts and hire staff as a corporation with a chosen name. The only thing it lacks is a distinctive legal name, and that is both its appeal and its drawback. The encyclopedia comparison of named and numbered corporations gives the short version; this article works through the decision.

Speed and certainty. A word name must clear a name search and may be refused if it is identical or confusingly similar to an existing name, misleading or otherwise non-compliant. A number name cannot be refused on those grounds, so a numbered company can be incorporated as soon as the articles are ready. Ontario's online incorporation fee is the same either way, $300 as of October 2026, but the numbered route avoids the cost and delay of a NUANS report.

Holding companies and special-purpose entities. Many corporations never deal with the public. A holding company that owns shares of an operating company, a corporation set up to hold a single rental property or an entity created to hold a family's investments has no customers to impress. A number name is the natural choice, and the encyclopedia entry on holding companies explains the structures in which they appear.

The name is not settled. Founders who are still testing a brand, or who expect to rebrand once the product finds its market, often incorporate as a number and defer the naming decision. Nothing is lost by waiting, because the corporation can adopt a name later.

Privacy and neutrality. A number name discloses nothing about the owners or the business. Investors who are assembling land, or owners who do not want a surname attached to the corporate record, may prefer that.

Several entities at once. An owner who creates a corporation for each project or property avoids inventing and clearing a new word name every time.

Your legal name appears on everything formal. Subsection 10 (5) of the Business Corporations Act requires a corporation to set out its name in legible characters in all contracts, invoices, negotiable instruments and orders for goods or services. If the corporation also operates under a registered business name, subsection 2 (6) of the Business Names Act requires both the registered name and the corporate name to appear on those documents. Customers of a numbered company therefore see 1234567 Ontario Inc. on every invoice and contract, even if the storefront says something else.

Banking and payments. The bank account is opened in the corporation's legal name. Cheques made out to an operating name are usually accepted once the business name registration is on file with the bank, but every new vendor, payment processor and government portal has to be shown both names.

Perception. Some customers, landlords and suppliers read a number name as a sign of a shell or a short-term venture. In consumer-facing businesses that impression costs sales. In business-to-business settings it rarely matters, and sophisticated counterparties are used to dealing with numbered entities.

Brand protection. A number name protects nothing. If the brand matters, the owner must separately register a business name, which gives notice but no exclusive right, and should consider registering a trademark, which does. A named corporation gets a measure of protection against identical Ontario corporate names; a numbered corporation operating under a trade name gets none.

A numbered company that wants to trade as Maple Street Bakery does not need to change its legal name. It registers Maple Street Bakery as a business name. Subsection 2 (1) of the Business Names Act provides that no corporation shall carry on business or identify itself to the public under a name other than its corporate name unless that name is registered by the corporation.

The registration is filed through the Ontario Business Registry. Ontario's fee table lists $60 for a new registration and $60 for a renewal, with amendments and cancellations at no charge, as of October 2026. Under subsection 4 (1.1) of the Act, a registration is effective for five years from the date the Registrar accepts it. Section 5 allows renewal before expiry and, on payment of a late fee, within 60 days after expiry; the Ontario Business Registry notes that the renewal option appears six months before the expiry date and that a registration expired for more than 60 days cannot be renewed and must be registered again. Subsection 4 (4) requires an amended registration within 15 days after any change in the registered information. The registry does not send reminders, so the renewal date belongs on the corporation's compliance calendar.

The consequences of skipping registration are specific. Section 7 provides that a person carrying on business in contravention of section 2 is not capable of maintaining a proceeding in an Ontario court in connection with that business except with leave of the court, which is granted where the failure was inadvertent, nobody was misled and the person is now compliant. Subsection 7 (3) confirms that contracts are not void merely because a party was unregistered. Section 10 makes contravention an offence punishable by a fine of up to $2,000 for an individual and $25,000 for a corporation.

What registration does not do is equally important. It records that a particular registrant is using a name; it does not reserve the name or stop someone else from registering an identical or similar one. Section 6 gives a person whose registered name or own name is copied a statutory claim for compensation against the registrant, limited to the greater of $500 and actual damages, together with an order cancelling the offending registration. That is a remedy, not a shield. Before settling on an operating name, run a preliminary business name search to see who else is using it and whether the matching domains and trademarks are taken.

Many numbered companies eventually adopt a word name, usually because a lender, franchisor or major customer wants the legal name to match the brand. The Business Corporations Act makes this easier than most amendments. Under subsection 168 (4), where a corporation has a number name, the directors may amend the articles to change it to a name that is not a number name. No special resolution of shareholders is required for that particular change, although a shareholder agreement may still call for consent.

The mechanics are the same as any other corporate name change: an Ontario-biased NUANS report supporting the new name, a directors' resolution, articles of amendment filed through the Ontario Business Registry for a government fee of $150 as of October 2026, and a certificate of amendment that fixes the effective date. The corporation then updates its business name registration, the Canada Revenue Agency, its bank, its contracts and its signage. Our guide to changing a corporate name in Ontario sets out each step, including the mistakes that leave the old name on title documents and leases.

The reverse is also available: a named corporation can amend its articles to become a numbered company, which some owners do when a business is sold and the buyer takes the name.

The most common numbered company in Ontario is a holding company sitting above an operating company. The operating company carries the brand, the customers, the employees and the risk. The holding company owns the operating company's shares and receives dividends from it, which can then be reinvested or held away from the operating business's creditors. A number name suits the holding company because nobody outside the family and its advisers ever deals with it.

Two cautions apply. First, a holding company structure has tax consequences, including rules on inter-corporate dividends, the sharing of the small business limit among associated corporations and the treatment of passive investment income, which should be modelled by an accountant before the structure is created. Second, money that moves between the companies must be documented. Our article on intercompany loans explains why informal transfers between a numbered holding company and its operating subsidiary cause problems on audit and on sale.

1. 1.Will the corporation deal with the public under a brand? If yes, a word name or a registered business name is needed; weigh whether the legal name should match.
2. 2.Is the corporation a holding company, a single-asset entity or a vehicle whose name will never be seen? A number name is usually sufficient.
3. 3.Is speed the priority, or is the brand still undecided? Incorporate as a number now and amend later under subsection 168 (4).
4. 4.Will a lender, franchisor, landlord or major customer want the legal name to match the brand? Plan the name change before signing.
5. 5.Whatever you choose, register any operating name under the Business Names Act, note the five-year renewal, and consider a trademark for the brand itself.

This article is general information about Ontario business corporations. Federal corporations, not-for-profit corporations and professional corporations, which cannot have a number name, follow different rules. Lamba Law's incorporation and structuring practice can incorporate a numbered or named company, register operating names and prepare the articles of amendment when the time comes. Our guide to registering a corporation in Ontario covers the full process.
