Starting a sole proprietorship is one of the simplest and most common ways to start a business in Ontario. It’s flexible, low-cost, and offers direct control, but it also comes with personal liability. This blog outlines the basic legal steps and key considerations for setting up and operating a sole proprietorship in Ontario.
1. What is a Sole Proprietorship in Ontario?
A sole proprietorship is an unincorporated business owned by one individual. Legally, there is no distinction between the business and the owner. This means:
- The owner reports business income and expenses on their personal tax return
- The owner is personally liable for all business debts and obligations.
Thinking of starting your own business? Start by choosing a name that reflects your brand, but don’t forget to check if it needs to be registered. Need help? We can guide you through that first step.
2. Do I Need to Register My Business?
In Ontario, you only need to register your business name if you’re operating under a name other than your own legal name.
- Registration is done through ServiceOntario, either online or in person.
- Registration must be renewed every five years.
- The governing law is the Business Name Act (Ontario).
Thinking long-term: The way you register your business today can affect future opportunities like incorporation or partnership. We can help you plan for both.
3. What Are Your Tax and License Requirements?
Once registered, you may need to:
- Apply for a Business Number (BN) with the CRA for tax purposes.
- Register for HST if your business makes over $30,000 in annual taxable revenue.
- Obtain municipal licenses or permits, depending on your business type and location.
Are you unsure which registrations apply to your business? Every industry has different tax and licensing needs — we can help you identify what’s relevant before your launch.
4. How is Income Reported?
Sole proprietor must:
- Report business income on their T1 personal income tax return, using Form T2125 (Statement of Business or Professional Activities).
- Keep detailed records of income and expenses, including receipts, invoices, and bank statements.
Sole proprietors are also responsible for:
- Contributing to the Canada Pension Plan (CPP) based on their net income.
- Making installment payments if they owe more than $3,000 in income tax each year.
Planning your first tax filing as a sole proprietor: Speaking with a business lawyer or accounting professional early can help you stay organized and compliant.

6. When Should a Sole Proprietor in Ontario Consider Incorporating?
If your business grows or if liability becomes a concern, you may want to consider:
- Incorporation provides limited liability protection.

Next Steps: Incorporating introduces new legal obligations and reporting requirements, so it’s wise to consult a lawyer before taking that step.
