Starting a business is exciting, but it can also feel overwhelming. Maybe you’re unsure how to separate your personal and business finances. Maybe you’re worried about tax rules or feel stuck because bigger clients want to work only with registered businesses. These are common concerns, and the good news is that registering your business in Ontario can help solve them. It gives your business a real identity, makes it easier to open a bank account, collect and remit HST, and apply for funding or government support. Most of all, it shows the world that you’re serious, ready to build something real, professional, and credible.
Choosing the Right Structure Before You Register
Before registering, you’ll need to decide how your business will be structured. In Ontario, your main options are:
Sole Proprietorship
A simple and affordable option where you are the sole owner. You’re personally liable for any business debts. This structure is ideal for freelancers and solo consultants. Registration costs $60 online or $80 by mail.
Partnership
If you’re starting a business with one or more partners, this is a common route. All partners share responsibility for business operations. The fee is the same as for sole proprietorships.
Corporation
A corporation is a separate legal entity, which limits your personal liability. It’s more complex to set up and manage, and registration costs $300 online or $360 by mail. It may offer tax advantages and is often preferred by those planning to raise capital or scale.
Tip: Choose a structure based on your business goals, financial plans, and how much personal liability you’re comfortable with.
What You Need Before Registering a Business in Ontario
Before you start the registration process, make sure you have:
- A unique business name: For corporations, you’ll also need a NUANS report to ensure your name is not already in use (typically costs $25–$50).
- A business address in Ontario (can be a residential or commercial address).
- A short business activity description: Just a line or two about what you do (e.g., web design, online tutoring, etc.).
- A contact person for communication with government offices and CRA.
Step-by-Step Guide to Registering a Business in Ontario
1. Choose Your Business Structure
Decide whether to operate as a sole proprietor, a partnership, or a corporation.
2. Name Your Business
Do a name search using the Ontario Business Registry. If incorporating, order a NUANS report to confirm the name is available.
3. Register with ServiceOntario
Go to the Ontario Business Registry and register your business. It takes around 20–30 minutes if you have everything ready. You’ll receive your Ontario Business Identification Number (BIN) upon completion.
Fees:
- Sole Proprietorship/Partnership: $60 online
- Corporation: $300 online
4. Set Up CRA Accounts
Once registered, apply for a federal Business Number (BN) and register for CRA accounts, such as:
- GST/HST (required once you exceed $30,000 in annual revenue)
- Payroll (if you hire employees)
- Corporate income tax (for incorporated businesses)
This can be done online through the CRA Business Registration Online portal.
5. Get Any Required Licences or Permits
Check if your city or industry requires a business license, zoning approval, or professional certification. For example, food businesses may need a health inspection permit.
What to Do After Registering
- Open a business bank account using your BIN and registration documents.
- Set up bookkeeping to track all income and expenses from day one.
- Register for WSIB (Workplace Safety and Insurance Board) if your business has employees and operates in a covered industry.
- Apply for trademarks or domain names to protect your brand.
- Get insurance suitable for your business activities.
Keeping personal and business finances separate is crucial for both organization and tax compliance.
Common Mistakes to Avoid
- Registering a name without checking its availability first
- Delaying CRA registration for HST or payroll
- Mixing personal and business funds in the same bank account
- Ignoring local permits or industry-specific regulations
- Choosing the wrong business structure for your long-term goals
