How to Register a Business in Ontario Canada (2024)

Ontario, one of Canada’s most prosperous and populated provinces, offers many opportunities for aspiring entrepreneurs. As the business world grows and evolves, so does the importance of ensuring that your entrepreneurial endeavors are grounded in legality and professionalism. Registering your business is not just a formality; it\’s crucial to establish your brand and ensure its protection.

Brief Overview of the Importance of Registering a Business

Starting a business without proper registration is akin to building a house without a solid foundation. Registration not only gives your business a legal identity but also provides legitimacy in the eyes of customers, suppliers, and financial institutions.


Legal Identity and Protection: Registering bestows upon your business a unique identity. It differentiates your brand and ensures that no other entity can operate or stake a claim under the same name. Moreover, registration can shield business owners from liabilities, protecting personal assets from potential business debts or lawsuits.

  • Credibility and Trust: A registered business automatically elevates the trustworthiness of your enterprise. Clients or customers who see that a business is registered are often more inclined to trust its products or services. This is because a registered business gives an impression of professionalism and dedication.

Access to Financial Services: Financial institutions, like banks, often require businesses to be registered before they offer business bank accounts, loans, or other financial services. A registered business can also benefit from government grants, tax benefits, and other incentives.

Benefits of Legally Registering a Business in Ontario

With its booming economy and strategic location, Ontario offers entrepreneurs numerous advantages. Here\’s why registering a business in Ontario is a lucrative decision:

Robust Business Infrastructure: Ontario boasts world-class infrastructure facilities, including transport, technology, and a skilled workforce. This makes it an ideal place for businesses to thrive.

Government Support and Resources: The Ontario government provides a wealth of resources for registered businesses, ranging from startup advice to training and development programs. There are also numerous grants and financial aids available for entrepreneurs to kickstart their ventures.

Network and Market Opportunities: With its diverse and vibrant market, Ontario is home to a multitude of industries. Registering a business here can open doors to collaborations, partnerships, and a vast customer base.

Understanding Business Structures


Before registering a business in Ontario, it\’s essential to understand the different business structures available. Your choice will influence various factors, from how much you pay in taxes to how much of your personal assets are at risk. Here\’s a breakdown:

Sole Proprietorship

A sole proprietorship is the simplest form of business structure where an individual owns and operates the business. The owner is solely responsible for all decisions, profits, liabilities, and debts of the business.

Advantages & Disadvantages:

    • Simplicity and Low Cost: Easier and less expensive to set up compared to other business structures.
    • Direct Control: The owner has total decision-making power.
    • Tax Simplicity: Business income is declared on the owner\’s personal income tax return.
    • Unlimited Liability: The owner is personally liable for all business debts and liabilities.
    • Limited Financial Resources: Raising funds can be more challenging as financial institutions may perceive more risk.



Definition: A partnership involves two or more individuals or entities running a business together. The partners share the profits, losses, and management of the business.

Types of Partnerships: General & Limited:

    • General Partnership: All partners are involved in the day-to-day management of the business and have unlimited liability for business debts and obligations.
    • Limited Partnership: Some partners (limited partners) invest capital but do not participate in daily management. They have limited liability, which means they are only liable up to the amount they\’ve invested. General partners in a limited partnership have unlimited liability.



A corporation is a legal entity separate from its owners (shareholders). It can earn income, incur liabilities, and enter contracts. Owners hold shares of the corporation.

Advantages & Disadvantages:

    • Limited Liability: Shareholders are typically only liable for the amount they invested in the corporation.
    • Capital Acquisition: Easier to raise funds through the sale of stock.
    • Corporate Tax Rates: May benefit from lower corporate tax rates.
    • Complexity and Cost: More expensive and complex to establish and maintain than other business structures.
    • Regulation: Subject to more government regulations.
    • Double Taxation: Corporations pay taxes on their income, and shareholders also pay taxes on dividends received.

Decide on the Most Suitable Structure for Your Business:

Your choice of business structure will be influenced by the nature of your business, your personal preferences, financial capacity, and risk tolerance. Here are some guiding questions:

  • Do you prefer to run the business by yourself or with partners?
  • How much personal liability are you willing to assume?
  • What are your financing needs and how do you plan to raise capital?
  • What are the tax implications for each structure?
  • How much control do you want over the business?

By understanding the characteristics, advantages, and disadvantages of each structure, you can make an informed decision that best suits your business goals and needs in Ontario.

Name Your Business

Importance of a Unique and Memorable Name

Your business name is often the first impression you make with potential customers. A unique and memorable name can set your business apart, reflecting your brand\’s values, essence, and purpose. It aids in brand recognition, generates interest, and can be a vital tool in marketing and brand-building efforts.

Search for Name Availability

Before settling on a name, you must ensure it is available and doesn\’t infringe on existing trademarks.

Using NUANS (Newly Upgraded Automated Name Search): NUANS is a search system used to check the availability of a business name in Canada. A NUANS report provides a list of existing businesses and trademarks that are similar to the proposed name, helping you determine if your desired name is distinguishable from others.

Ensuring Name Doesn\’t Infringe on Trademarks: A trademark is a right granted for a word, symbol, or combination used to identify goods or services. Before finalizing your business name, consult the Canadian Trademarks Database to ensure your desired name isn\’t too similar to an existing trademark, which could lead to legal disputes.

Rules and Regulations for Naming Businesses in Ontario


When naming your business in Ontario, there are certain rules you must follow:

  • The name should be distinctive and not be too general.
  • It should not be misleading or give a false impression about the business\’s nature.
  • Avoid names that suggest connection with the Crown, a government agency, or specific professions unless authorized.
  • Names suggesting affiliation with certain institutions or professions (e.g., \”university\” or \”engineer\”) may have restrictions or require additional consent.

Registering Your Business

Determine If You Need to Register

Before diving into the registration process, it\’s important to determine if registration is even necessary for your business.

Exceptions to Registration Requirements:

Operating under your legal name without any additions does not require registration.

Certain professions (like lawyers or health professionals) might be exempt from typical registration procedures but may have to register with their respective regulatory body.

Gathering Necessary Information & Documents

Be prepared to provide:

  • Your desired business name.
  • A brief description of the business activity.
  • Business address and contact details.
  • Owner\’s name and address.

Choose a Method of Registration:

  • Online Using ONe-Source for Business: The Ontario government\’s online portal streamlines various business-related processes, including registration. This is often the fastest and most convenient method.
  • In-Person at a ServiceOntario Centre: For those who prefer face-to-face interactions, visiting a ServiceOntario centre is an option. Make sure to bring all necessary documents.
  • By Mail or Fax: You can also send your registration details via mail or fax. Ensure all forms are filled out correctly to avoid delays.

Pay the Registration Fee

The cost of registration varies based on the business structure (e.g., sole proprietorship, corporation) and the method of registration. Ensure the payment is made promptly to avoid any delays in the process.

Obtain a Business Identification Number (BIN)

Upon successful registration, you\’ll receive a Business Identification Number (BIN). This unique identifier is essential for various business activities, like renewing your registration or interacting with government agencies.

Other Key Registrations and Licenses

Register for HST (Harmonized Sales Tax) if Applicable

Ontario-owned businesses with sales over a specific threshold must register for and collect HST. Ensure you understand the current limit and register if your business\’s revenue surpasses it. Registering can also allow you to reclaim the HST you\’ve paid on business-related purchases.

Employer Health Tax (EHT) If Hiring Employees

When you hire employees, your business may be subjected to the Employer Health Tax (EHT). This tax is levied on the remuneration paid to employees. It\’s essential to understand the exemptions and rates associated with EHT to ensure compliance.

Workplace Safety and Insurance Board (WSIB) Registration

The WSIB provides no-fault workplace injury insurance for employers and workers. Registering with the WSIB ensures that you have coverage for potential workplace injuries, offering protection and peace of mind for both employers and employees.

Obtain Any Special Permits or Licenses

Depending on the nature of your business, you may require specific permits or licenses. For instance:

  • A liquor license is necessary if you\’re selling or serving alcohol.
  • A food establishment license is required for restaurants, cafes, and some food stalls.
  • Always check local and provincial regulations to ensure you have all the necessary permissions to operate legally.

Business Banking & Finances

Importance of Keeping Business and Personal Finances Separate

For transparency and simplifying tax filing, it\’s crucial to separate personal and business finances. This distinction also offers clarity about your business\’s financial health and shields personal assets from potential business debts.

  • Open a Business Bank Account

With your registration and Business Identification Number (BIN) in hand, approach a bank to open a business account. This step will help you manage business funds, facilitate transactions, and streamline your financial records.

Consider Credit Options for Your Business

Depending on your business needs, consider obtaining a business credit card or line of credit. This can aid in managing cash flow, financing purchases, or expanding operations.

Stay Updated on Regulations and Compliance

Importance of Regular Compliance Checks

Regularly review provincial and federal regulations to ensure your business remains compliant. This proactive approach prevents potential legal and financial pitfalls.

Renewing Business Registration

Ontario business registrations typically expire after five years. Stay vigilant about renewal deadlines to avoid lapses and potential legal consequences.
