Ontario Business Registration: Step-by-Step Guide for 2026

Starting a business in Ontario is exciting. The first critical step is Ontario business registration. This process makes your business official. It creates a legal identity for your venture. Proper registration is not optional. It is a legal requirement in most cases. This guide covers all the steps for Ontario business name registration in 2025. It details how to use the Service Ontario business registration platform. Getting this right sets a strong foundation for your success.

What Is Business Registration in Ontario?

Business registration is the act of formally recording your business with the provincial government. It provides official recognition. This process ensures compliance with the Business Names Act.

When is it required?

You need to register if you are operating under a business name that is not your own legal name. This applies even to sole proprietors. For example, if your name is Jane Doe, you don’t need to register if you operate as “Jane Doe.” However, if you call your business “Jane’s Consulting Services,” business name registration is mandatory. This also applies to partnerships and corporations. This registration is done through the official Service Ontario business name registration process.

Important legal consequence: An unregistered business cannot maintain a legal proceeding in an Ontario court under its unregistered name. That means if a client doesn’t pay you, you cannot sue under your business name until your registration is in order. Don’t let this happen to you.

Ontario Business Registration Cost

Understanding the Ontario business registration cost before you start helps you budget properly. Here is the breakdown of current government fees:

Business Type	Online Fee	Renewal Required
Sole Proprietorship	$60	Every 5 years
General Partnership	$60	Every 5 years
Limited Liability Partnership (LLP)	$60	Every 5 years
Ontario Limited Partnership	$210	—
Corporation (Provincial, online)	$300	Annual filings required
NUANS Name Search Report	$13–$60	Per use (valid 90 days)

Key cost notes:

• All registration fees are non-refundable, regardless of outcome.
• Corporations incorporating with a chosen name must obtain a NUANS report before filing. This confirms your name is unique and doesn’t conflict with existing registered names across Canada. The report is valid for 90 days.
• Choosing a numbered company (e.g., “1234567 Ontario Inc.”) skips the NUANS requirement, reduces cost, and speeds up incorporation. Many businesses start this way and register a trade name separately later.
• Third-party licensed service providers typically charge an additional $100–$400 in service fees on top of government fees.
• Failure to register when required can result in fines of up to $2,000 for individuals or $25,000 for corporations under the Business Names Act.
• Mail-in submissions cost the same as online but take approximately 15 business days to process compared to immediate processing online. There is no good reason to file by mail if you need your registration quickly.

Types of Business Structures in Ontario

Choosing the right legal structure is key. It affects liability, taxation, and administration. Ontario offers three main structures.

Sole Proprietorship

• Definition: This is the simplest structure. It is owned and controlled by one person.
• Liability: You and your business are legally one entity. You are personally responsible for all business debts. This is known as unlimited liability.
• Taxation: Business income is reported on your personal tax return (T1).
• Registration: If you use a name other than your own, you must register the sole proprietorship Ontario business name.

Partnership

• Definition: Two or more individuals share ownership. They operate the business for profit.
• Liability: Similar to a sole proprietorship, partners are personally liable for business debts. Each partner can be responsible for the full amount.
• Taxation: Each partner reports their share of the partnership’s income on their personal tax return.
• Types: There are General Partnerships and Limited Partnerships (LP). LPs offer some limited liability to passive partners.

Corporation

• Definition: This is a separate legal entity. It is distinct from its owners (shareholders).
• Liability: Shareholders have limited liability. Their personal assets are generally protected from business debts.
• Taxation: The corporation pays its own taxes. This is done on a separate corporate tax return (T2). Owners who work for the corporation are taxed as employees.
• Setup: This is the most complex and costly structure to set up. The provincial incorporation fee is $300 when filing online through the Ontario Business Registry. Note that some sources cite $320 for online filing  always verify the current fee on the official Ontario government website before submitting, as fees are periodically updated.

How to Register a Business Name in Ontario

The registration process is largely completed online. The official portal is the Ontario Business Registry (OBR). This ensures a fast and efficient process.

Step-by-Step Registration

1. Choose Your Name: Select a unique name that complies with Ontario’s naming rules. Before registering, search the Ontario Business Registry online for free to check if your name is already taken. This free search is available to anyone, no account required. Also check domain name availability at the same time. For corporations registering with a specific name, a NUANS report is mandatory before filing.
2. Access the Ontario Business Registry: Visit the official OBR at ontario.ca. You will need a My Ontario Account, which links to an Ontario Business Account for managing all transactions. If your business was registered before October 19, 2021 (the OBR launch date), your information was migrated from the old system. You still need to set up an Ontario Business Account and use your company key (a unique 9-digit code) to link your entity to your account going forward.
3. Select Your Filing: Choose the specific transaction. This could be “Register a Sole Proprietorship” or “Incorporate a Business Corporation.”
4. Complete the Form: Enter all required details accurately. This includes the business name, address, business activity, and owner information.
5. Pay the Fee: The fee depends on the business structure. A business name registration for a sole proprietorship is currently $60. Fees are paid online.
6. Get Your Master Business Licence (MBL): Once complete, you receive confirmation and your MBL. This document includes your Business Identification Number (BIN). This is proof of your service Ontario business name registration.
7. Keep Information Updated: You are legally required to update your information in the OBR within 15 days of any change to your business details. The government uses your registered email address for official notices, so keep it current.

Getting Your Ontario Business Number (BN)

The registration process gives you a Business Identification Number (BIN) from the province. However, a separate number is also essential. This is the federal Ontario Business Number (BN).

The BN is a unique 9-digit identifier. The Canada Revenue Agency (CRA) issues it. You need it to deal with federal programs. This includes GST/HST, payroll, and corporate income tax.

How it Links

For corporations, the BN is often automatically assigned after incorporation. For sole proprietorships and partnerships, you may need to apply for it separately. This is done through the CRA. You will use your provincial business registration details (like your BIN) when applying.

Ontario Business Registration for Immigrants and Newcomers

However, there are important eligibility and practical considerations newcomers must understand first.

Who can register a business in Ontario?

You can register if you are:

• A Canadian citizen or permanent resident
• A temporary resident with a valid work permit that authorizes self-employment
• A foreign national operating through a corporation (specific rules apply per your immigration category)

1. Confirm eligibility with IRCC before registering.
2. Check regulated profession requirements. If your field is regulated in Ontario (e.g., engineering, medicine, real estate, accounting), you may need a license or professional certification before operating. Contact Global Experience Ontario at 1-866-670-4094 for guidance.
3. Register through the OBR. The same online portal all Ontario businesses use. There is no separate process.

• Payroll: If you plan to hire employees, you must register a payroll account with the CRA. This is for source deductions.

WSIB Registration

The Workplace Safety and Insurance Board (WSIB) provides insurance. It covers employees for work-related injuries or illnesses. Most Ontario businesses with employees must register with WSIB. There are some industry exemptions.

Permits and Licenses

Provincial registration does not cover local rules. Check your specific municipality for required permits or licenses. Your business activity may also require industry-specific permits.

Proper CRA business registration is the foundation for all future filings. Always keep your registration documents safe.

Maintaining Your Registration

Your Ontario business name registration does not last forever. Sole proprietorships and general partnerships must renew every five years through the OBR.

You will receive a reminder notice, but it is your legal responsibility to file on time. Operating under an expired registration carries the same legal penalties as operating unregistered.

Corporations do not have a five-year renewal, but they must file annual returns through the OBR to remain in good standing. Missing annual filings can result in your corporation being dissolved by the province.
