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.
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.
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
- Choose Your Name: Select a unique and compliant name. Check that it follows naming rules. For corporations, a more extensive NUANS name search report is often required.

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.
