Starting a small business is an exciting journey, but for many first-time entrepreneurs, the registration process can seem intimidating. If you’re planning to operate in Ontario, understanding the steps involved — from deciding if you need to register to knowing what comes after — will make the process much smoother. This guide walks you through everything you need to know.
Do I Need to Register My Business?
In Ontario, registration is required if you are conducting business under any name other than your exact legal name. For example:
- No Registration Needed: John Smith operating as “John Smith”
- Registration Required: John Smith operating as “Smith Landscaping”
Even if you aren’t legally required to register, doing so can help you open a business bank account, apply for permits, and present a more professional image to clients.
Why Is Registration Mandatory in Some Cases?
Registration ensures your business name is recorded with the Ontario Business Registry and gives your business a legal presence. It also helps protect consumers by making business information available for public search. Operating without required registration can result in penalties or difficulty accessing business services.
What Legal Structures Are Available in Ontario?
Choosing the right legal structure will affect your taxes, liability, and ability to grow. The most common options include:
- Sole Proprietorship: Owned by one person, easy and inexpensive to start, but the owner is personally responsible for all debts and liabilities.
- General Partnership: Owned by two or more people, sharing responsibilities, profits, and liabilities.
- Corporation: A separate legal entity that provides liability protection, can offer tax benefits, and may attract investors.
Your choice depends on your goals, budget, and tolerance for risk.
| Structure | Cost | Liability | Taxation | Ideal For |
| Sole Proprietor | Low | Personal | Personal | Freelancers, trades |
| Partnership | Medium | Shared liability | Shared income | Family businesses |
| Corporation | High | Limited | Corporate tax | Growth-focused startups |
How to Choose a Business Name
Your business name should be unique, easy to remember, and reflective of your brand. It cannot be misleading or too similar to an existing registered name. Certain words, like “Bank” or “University,” require special permission to use.
To avoid rejection, conduct a NUANS preliminary name search to check availability before registering.
Where to Register Online
You can register directly with the Ontario Business Central, which provides:
- Same-day completion

- Email reminders for renewals
- Live Canadian support by phone, email, or chat
What is a Business Identification Number (BIN)?
When you register a Sole Proprietorship, General Partnership, or trade name in Ontario, you’ll receive a Business Identification Number — a unique nine-digit code used for Ontario government filings. This is different from a Canada Revenue Agency (CRA) Business Number, which you may need for tax purposes.
Licences & Permits You May Need
After registering your business name, you may also require licences or permits depending on your industry and location. Examples include:
- Municipal business licences
- Zoning permits
- Industry-specific certifications (e.g., health permits for food service)
You can use the Government of Canada’s BizPaL tool to identify requirements.
What Happens After Registration?
Once you’ve registered, you’ll receive your official registration documents and BIN. The next steps often include:
- Registering for a CRA Business Number
- Setting up a business bank account
- Registering for HST if your revenue exceeds $30,000/year
- Setting up payroll accounts if hiring employees
- Obtaining any required licences or permits
- Purchasing insurance for protection
