To register your business as a corporation in Canada, the first step is to search a corporate name. The provinces of Alberta, Ontario, Nova Scotia, New Brunswick and PEI use Nuans search reports for their respective provinces to search and reserve a corporate name for their respective jurisdiction.

We recommend that you pick a short name that has a matching domain name available.

Search for a .com and .org domain names at Uniregistry (a new secure window will open):

Always order a Nuans Pre-search or a Nuans full search before registering a business name. The cost of changing your name later and dealing with lawsuits may cripple your business.

Business Registration

In most provinces in Canada, you may obtain a business registration for a business name by registering a:

The Partnerships Act provides two types of partnerships:

  • General Partnership, and a
  • Limited Liability Partnerships (LLP)

A limited liability partnership (LLP) is a partnership in which limited partners have limited liability. It exhibits elements of both partnerships and corporations. In an LLP, a limited partner is not responsible or liable for another partner’s misconduct or negligence.

In Ontario, the Partnerships Act permits certain professionals to practice in a limited liability partnership if they meet the following criteria:

  • the Act governing the profession expressly permits a limited liability partnership to practice the profession;
  • the governing body of the profession requires the partnership to maintain a minimum amount of liability insurance; and
  • the partnership registers its name under the Business Names Act.

Register A Business Name in Ontario

You may register a business name as either a sole-proprietorship or a partnership and get a Master Business Licence in Ontario, for $60, at the Ontario government website:

You may use your Master Business Licence as proof of your business name registration at financial institutions and in business transactions with the Ontario government. It is valid for 5 years and it must be renewed within 6-months of expiry, otherwise you will lose your business name registration.

Trade Name Registration

A Master Business Licence is proof of ownership of a trade name. Trade names may be used to block future applicants of trademarks for confusingly similar names.

Ontario corporations may register a trade name at:

Only corporations are available for Federal business registration in Canada, through Industry Canada’s website. You may not Federally register a trade name as either a sole-proprietorship or a partnership. Trade names are registered only in the Provinces where you do business.

You may obtain a business registration for a foreign LLC in Canada. Limited Liability Company “LLC” is popular in many US states and in Europe, but they are almost all a little different based on the operating agreement filed for the LLC and the various state laws that they may be registered under.

ULC is a business registration only available in Nova Scotia. Unlimited Liability Company “ULC” entities appear to have no Canadian residency requirements. They are often called CRA “check the box” tax flow through entities for foreign persons doing business in Canada. None of ULC’s members appear to need to be residents of Canada.


DBA and “Operating As”

The phrase “doing business as” (abbreviated DBA, dba or d/b/a) is a legal term used in the United States and sometimes in Canada, meaning that the trade name, or fictitious business name, under which the business or operation is conducted and presented to the world is not the legal name of the legal person (or persons) who actually own it and are responsible for it. In Canada, the expressions operating as (abbreviated o/a) or trading as (abbreviated T/A) are more common.

In Ontario, businesses are often registered as a numbered corporation, such as “1168087 Ontario Inc.” and then the business may operate as “Skin Care Spa” if it also registers “Skin Care Spa” as a trade style, which must be renewed with the Ontario government every five years. Entrepreneurs do this for a number of reasons, such as:

  • The business will operate multiple lines of businesses, each with a different name
  • The desired name might not have been registrable,
  • The business operates as a franchisee, or
  • The business wants flexibility in changing its operating name.
  • Register your DBA at:

Note, all legally binding transactions taking place on behalf of the actual corporation’s name and not the operating as name.

The distinction between an actual and a “fictitious” name is important because businesses with “fictitious” names give no obvious indication of the entity that is legally responsible for their operation.

In Ontario, Canada, when a businessperson writes a trade name on a contract, invoice, or check, he or she must also write the legal name of the business. Ontario mandates this requirement with its Business Names Act.

Legal Ending of a Corporation’s Name
All for-profit corporation names must have a single legal ending, selected from one of the following endings in most Provinces:



Numbered Companies and Trade Styles

Often people will incorporate a business with a numbered name, such as “1908087 Ontario Inc.” or “7935978 CANADA INC.” and then register a trade style as their operating name or DBA, such as “Joe’s Pizza,” which is only a division of the corporation. A trade style is not a separate corporation and you cannot then just add a legal ending to it, such as “Joe’s Pizza Limited,” according to Ontario’s Business Corporations Act:

Unauthorized use of “Limited”, etc.

11. (1) No person, while not incorporated, shall trade or carry on a business or undertaking under a name in which “Limited”, “Incorporated” or “Corporation” or any abbreviation thereof, or any version thereof in another language, is used. R.S.O. 1990, c. B.16, s. 11 (1).

(2) Where a corporation carries on business or identifies itself to the public by a name or style other than as provided in the articles, that name or style shall not include the word “Limited”, “Incorporated” or “Corporation”or any abbreviation thereof or any version thereof in another language. R.S.O. 1990, c. B.16, s. 11 (2).
