How to Register a Business in Ontario (2023): Step-By-Step Guide for New Entrepreneurs

When starting a business in Ontario, you have a lot of things to think about as part of the setup process. One thing you will not want to forget is registering your business with the Ontario provincial government.

By registering, you inform the government about the legal structure you are using with the business. This legal structure plays a role in how much personal liability you have for the operation of the business, as well whether your personal finances intertwine with the business’ finances. It also plays a role in the calculation of your taxes.

Do I Need to Register My Business in Ontario?

According to the Ontario provincial government, you must register your business with Ontario if you have employees, if you are operating facilities, or if you open an office within the province. This applies to almost any kind of business in operation in Ontario.

However, if you are operating a sole proprietorship in Ontario and if you are using your own name as the business name, you do not have to register. You only must register a sole proprietorship in Ontario if you are using a distinct business name.

Types of Business Registration in Ontario

You can select among four different legal structures when registering your new business in Ontario.

1. Sole Proprietorship

The sole proprietorship legal structure works best for a single owner operating a small business. Such businesses are easy to set up and typically do not have a significant amount of expenses and income.

With a sole proprietorship, the finances of the business and your personal finances mix together. No separation exists for the liability of the business and your personal life, either.

2. Partnership

Partnerships in Ontario can have two or more owners. Each partner shares in the profits and losses of the business, typically dividing them equally among all partners. (The partnership agreement can specify a different division, though.) Multiple types of partnerships are available in Ontario, including:

  • General partnership
  • Ontario limited liability partnership
  • Extra-provincial limited liability partnership
  • Limited partnership

Partnerships do not require a lot of time in the setup process. The partners’ finances and liability on a personal level are not separate from the business’ finances and liability.

3. Co-operative

Co-operatives are businesses that typically consist of many owners, each of whom has an equal vote in the operation of the business. Co-operatives can be for-profit or non-profit businesses.

The finances and liability of the owners personally remain separate from the finances and liability of the co-operative.

4. Corporation

A corporation is a common legal structure for a business in Ontario. The corporation requires some extra work in the setup process, and you must file forms annually. However, it offers numerous benefits, including that the owners’ personal finances and liability remain separate from the business.

Corporations can have one or multiple owners, and each owner can have a particular ownership percentage of the business, specified through ownership shares. Ownership shares can be privately held or publicly traded on a stock exchange.

Why Register a Business? Benefits of Registering a Business in Ontario

Although registering your business involves some expense and takes a bit of extra time, there are benefits to fulfilling the process, including:

  • Trust among customers: When you register your business and establish a brand name, customers will be more willing to trust you. Upon registration, your business name will differ from other business names in Ontario. Depending on the type of business you are running, having a unique business name can be extremely important.
  • Trust among suppliers: Suppliers may be more willing to give you a deal or to sign a contract with you when you have a registered business. If you aren’t registered, suppliers may not see you as a serious business.
  • Business banking: If you want to obtain a business banking account, you may need to have your business registered in Ontario. You could qualify for loans or special business credit cards when you officially have a registered business.
  • Planning for growth: Even if you do not want to register initially because you are a sole proprietorship operating under your own name, you will have to register if you grow later and have employees. You might want to register right away, so you don’t have to go through the process later.

When Do You Have to Register a Business in Ontario?

The Ontario provincial government requires that you register your business name within 60 days of opening your business.

    Most people will want to register the business name before opening it, though, as registration is the only way to be certain that you have protection for your business name. With that protection, you then can register a website domain name and social media accounts that match.

    You don’t want to obtain your website domain before officially claiming your business name, because some other business may have already taken your business name for its website.

    Ultimately, if you want the benefits that come with registering your business in Ontario, you cannot receive those until you go through the registration process. So, we recommend registering your business before you open the doors.

    How Much Does It Cost to Register a Business in Ontario?

    • General partnership: $60
    • Limited liability partnership: $60
    • Corporation: $300

    Steps to Register a Business in Ontario: Follow These 3 Steps

    These are the steps to register a business in Ontario:

    • Step #1: Name your business
    • Step #2: Decide the type of business (sole proprietorship, partnership, corporation)
    • Step #3: Register your business – you can register online, in person, or by mail (registering online saves you $)

    Let’s cover each step in detail:

    Step #1: Name Your Ontario Business

    The first thing you’ll want to do is settle on the business name, you’ll need to state it when registering.

    Check if an Existing Business Has the Name

    Before registering, it’s a good idea to know if there are already existing businesses with that name. While Ontario does not prohibit more than one non-incorporated business from having the same name, to avoid confusion and protect yourself from legal liability it’s usually a good idea to have a unique name.

    Restrictions on Business Names

    When deciding on a name, there are a few restrictions on naming your business you should be aware of:

    • Obscene or objectionable words or expressions, or words prohibited under federal or Ontario law.
    • A business name that could deceive regarding the type of business it is, e.g. using “LLC” in your business name if you are a sole proprietorship. “Limited”, “Limitée”, “Incorporated”, “Incorporée”, “Corporation”, or the corresponding abbreviations “Ltd.”, “Ltée”, “Inc.” or “Corp.” are prohibited, unless “limited” is used in the name of a limited liability partnership.
    • The words “college,” “institute” and “university” are prohibited without special permission.
    • Business names cannot imply a connection with the Canadian government or the Crown.
    • Using another person’s name is prohibited without their permission unless the person has been dead for more than 30 years.

    It is your responsibility to make sure your business name doesn’t violate these rules. Even if you are granted a registration, it could be revoked at any time if it is in violation.

    Step #2: Decide the Type of Ontario Business

    When registering your business, you need to understand what kind of legal entity you are registering. You can register a business name as a sole proprietorship, a general or limited partnership, or for an existing corporation.

    1. Starting a Sole Proprietorship in Ontario

    With a sole proprietorship, one individual owns all the assets, is responsible for any debts, and receives all the profit.

    Registering a Sole Proprietorship in Ontario

    If you are running your sole proprietorship under your personal name in Ontario, you do not have to register with the provincial government (although you can). However, if you want to run the sole proprietorship under another name, you must register.

    The registration process for becoming a sole proprietorship involves obtaining a master business licence. You will receive a Business Identification Number (BIN) from the Ontario government with your master business licence. It will describe your business name and address, too.

    Start by selecting a unique name for your business. Log in to your ServiceOntario account and complete the online form, which includes your contact information and other information about the business.

    You then must pay the $60 fee to register the sole proprietorship.

    2. Starting a Partnership in Ontario

    With a partnership, ownership is shared by two or more people who are either general partners or limited partners. The general partner or partners are fully responsible for all debts, liabilities, and obligations, while limited partners have limited liability based on their investment in the business.

    Registering a Partnership in Ontario

    You can register your partnership as a general partnership or as a limited type of partnership online. As with a sole proprietorship, your partnership will obtain a master business licence through the registration process.

    Select your business name and register it through your ServiceOntario account. (With some limited partnerships, you may have to agree to a certain type of naming format.) You’ll need to pay anywhere from $60 to $210 to register your partnership.

    3. Starting a Corporation in Ontario

    Registering a corporation (also called “incorporating” your business) creates a legal entity that separates owners from the business. You can incorporate at the provincial or federal level.

    Registering a Corporation in Ontario

    Registering your business as a corporation in Ontario requires you to obtain a NUANS name search for Ontario.

    Once you have your name selected, sign in to your ServiceOntario account and complete the online form. You also will need to submit your Articles of Incorporation. The fee is $300 to register a corporation in Ontario.

    4. Starting a Co-Operative in Ontario

    A co-operative is a type of business organization that is owned and democratically controlled by its members, who can be either individuals or other businesses. The purpose of a co-operative is to provide goods or services to its members, rather than to generate profits for shareholders.

    In Ontario, co-operatives are governed by the Co-operative Corporations Act, which outlines the rules and regulations that co-operatives must follow in order to operate in the province. Under this Act, co-operatives must have at least three members and are required to have a board of directors that is elected by its members.

    Co-operatives in Ontario can take many different forms, including consumer co-operatives, worker co-operatives, and housing co-operatives. These different types of co-operatives operate in various industries, including agriculture, finance, and retail.

    Registering a Co-operative in Ontario

    The process of starting and registering a co-operative requires following the Co-operative Corporations Act in Ontario.

    You may need to obtain a NUANS name search report to verify the name you want to use with your co-operative.

    You will need to complete the Articles of Incorporation of a Co-operative. The exact form you use will depend on whether you are filing with share capital or without share capital. You also must file a cover letter that includes your contact information, that describes the activity that the co-operative will do, and the company key (if applicable).

    When submitting your registration for an Ontario co-operative, you only can file by mail or email. You cannot file in person or through online forms. The cost is $335 for a for-profit co-operative and $155 for a non-profit co-operative.

    Step #3: Register Your Ontario Business – Online, By Mail, or In-Person

    Once you know your business name and the type of entity you want to form, you can apply for business registration with the government.

    You will need to provide:

    • Name of your business
    • Business address
    • Principle place of business
    • The name of the owner or partners and addresses (you can’t use a PO Box)
    • The types of activity the business conducts
    • The person authorizing the registration (usually the business owner, used if someone else is registering the business on behalf of another)
    • Business activity – A brief description of what makes most of your revenue, e.g., operating a restaurant, house painting, etc.
    Registering Your Ontario Business Online

    Registering your Ontario business online can be done in as little as five minutes. You’ll need a Visa or MasterCard credit card for payment, as well as an email address.

    If you’re going to register your business through the Ontario Business Registry, you need to:

    • See if your business name is available by searching the Ontario Business Registry
    • Create a ONe-key account, which provides an extra level of security for organizations accessing Ontario Government services
    • Register a ServiceOntario account through your ONe-key account
    • Register your business through your ServiceOntario account.

    Some business structures need additional forms, such as Articles of Incorporation when you are incorporating a business. The required forms will depend on the business legal structure you are using.

    Finally, you’ll need to have your registration fee available at the time of registration.

    To register online you use the “Integrated Business Services Application” service. You can register online at any time, however, if it’s done between 8:30 am. – 5 p.m. you’ll get a temporary printable Master Business License you can use right away.

    You’ll receive your MBL via email within 2 days if you provide an email address. If you don’t provide an email it will arrive by mail within 10 business days.

    If you need access to a computer, you can use a ServiceOntario centre to find a public computer near you.

    Registering Your Business by Mail

    To register by mail or in person, fill out Form 1. Complete the form and mail it with a payment of $80 in check or money order made out to “Minister of Finance.” Mail your completed forms and payment to:

    Ministry of Government and Consumer Services
    Central Production and Verification Services Branch

    Other Important Considerations When Registering a Business in Ontario

    Will you have employees or hire contractors?

    During the application process, you’ll have to answer if you have, or plan to have, employees or hire contractors.

    If you answer “yes” to either of those, you’ll need to register with the Workplace Safety and Insurance Board within ten days of hiring a worker. This provides employees with workplace insurance coverage. Note that you will still be able to register your name if you haven’t yet registered for insurance.

    Do you need Employer Health Tax?

    During the registration process, you’ll be asked if your estimated annual payroll is greater than $450,000. If so, you need to file for an Employer Health Tax number. Note that you will still be able to register your name if you haven’t filed yet.

    Potential Issues When Registering a Business in Ontario

    While you are in the process of completing your business registration there are several potential issues to keep in mind.

    • The business name already exists. One of the issues you could face is an already existing business having the same name. Refer to the business name search section above for more information.
    • Name restrictions. Make sure your business name doesn’t conflict with any of the restrictions on business names. Refer to the naming your business section above for more information.
    • Legal requirements. In addition to registering your business, there are likely additional legal requirements to comply with. Make sure you get the appropriate licenses, registration, or certificates needed to operate legally. Depending on the size and type of business, you may need to get a Federal Business Number (BN), Retail Sales Tax Vendor Permit, Employer Health Tax number, or register with the Workplace Safety and Insurance Board.
    • Changes to your business. You will have to submit a new business name registration if you change the name of your business, if there is any change in partners, or if there is a change in business type.
    • Canceling your registration. If you stop operating your business you should cancel your business name online, in person, or by mail. There is no filing fee to cancel a business.
    • Protect your business name. Simply registering your business does not mean you have exclusive rights to that name. This means that another business could use your name. If you want to protect your business name, you’ll have to register as a corporation or register a trademark.

    Make Sure You Renew Your Business Registration

    Business registration expires in five years. The expiration date will be printed on your MBL. It is your responsibility to make sure you renew it, CPVSB does not provide a reminder. Note that you can renew your business up to 60 days after it expires, but don’t let it get to that point!

    Checklist for Registering a Business in Ontario

    • Search the Ontario Business Registry or perform a NUANS name search to find your desired business name that differs from other business names in use in Ontario.
    • Create accounts with One-key and ServiceOntario to obtain the forms you need.

    • Submit any extra forms you need to match the type of legal business structure you are operating.
