Starting a business in Ontario is an exciting step toward entrepreneurship and financial independence. However, before you begin operations, one of the most important steps is registering your business. Business registration in Ontario not only makes your business legal but also allows you to open bank accounts, sign contracts, and build trust with customers and partners.
1. Why Register a Business in Ontario?
Registering your business in Ontario is a legal requirement if you operate under a name other than your own. It provides several benefits:
- Legal recognition of your business name
- Access to business banking and financing
- Protection and credibility with customers and suppliers
- Eligibility for tax benefits and government programs
- Ability to hire employees and expand legally
2. Types of Business Structures in Ontario
Before registration, it’s essential to choose the right business structure. The main types include:
a. Sole Proprietorship
- Owned and operated by one person
- Easiest and least expensive to register
- The owner is personally responsible for all debts and liabilities
b. Partnership
- Owned by two or more individuals
- Partners share profits, losses, and liabilities
- Requires a clear partnership agreement
c. Corporation
- A separate legal entity from its owners (shareholders)
- Offers limited liability protection
- More complex and costly to register, but ideal for long-term growth
3. How to Register a Business in Ontario
The process is straightforward and can be completed online through the Ontario Business Registry.
Step-by-Step Process:
- Choose a Business Name
- Search for name availability using the NUANS (Newly Upgraded Automated Name Search) system.
- Ensure your name is unique and doesn’t infringe on existing trademarks.
- Decide on a Business Structure
- Select whether you’re registering as a sole proprietor, partnership, or corporation.
- Register Online
- Visit the Ontario Business Registry website or use an authorized service provider.
- Provide required details such as business name, address, type of activity, and owner information.
- Pay the Registration Fee
- The cost typically ranges from $60 to $300, depending on the structure and method of registration.
- Receive Your Business Number (BN)
- After registration, you’ll receive a Business Number (BN) from the Canada Revenue Agency (CRA), which you’ll use for tax filings, GST/HST, payroll, and import/export accounts.
4. Renewal and Updates
- Sole proprietorships and partnerships must be renewed every five years.
- Corporations do not need renewal but must file annual returns to remain in good standing.
- Any changes to your business name, address, or ownership must be updated with the Ontario Business Registry.
5. Important Licenses and Permits
Depending on your business type and location, you may need additional licenses or permits:
- Municipal business licenses
- Health and safety permits
- Zoning approvals
- Industry-specific certifications
You can check the BizPal website (a Government of Canada service) to identify all required permits for your business.
