You have a business idea and you’re ready to move forward. Then the questions start. Should you register a sole proprietorship or incorporate? Do you need a business number from the CRA? What permits apply to your industry? How much will everything cost?
If you’re starting a business in Ontario, the process isn’t difficult, but there are several steps that need to happen in the right order. Missing one can create delays, extra costs, or tax headaches later. This guide walks you through the entire process, from choosing a business structure to registering with government agencies, opening business accounts, and preparing for your first customers.

What Business Structure Should You Choose in Ontario?
Your first major decision is selecting a business structure.
Think of it like choosing the foundation of a house. Everything else sits on top of it.
Most new entrepreneurs choose one of three options:
Sole Proprietorship
A sole proprietorship is often the simplest and least expensive structure.
Advantages include:
- Lower startup costs
- Simpler administration
- Easier tax reporting
- Faster registration
Potential drawbacks:
- Personal liability for business debts
- More difficulty attracting investors
- Limited separation between personal and business assets
Corporation
A corporation becomes a separate legal entity.
Advantages may include:
- Limited liability protection
- Easier ownership transfers
- Better investor opportunities
- Potential tax planning benefits
Potential drawbacks:
- More paperwork
- Annual filing requirements
- Higher setup costs
Partnership
Partnerships can work well when two or more people start a business together.
However, partnership agreements should be documented carefully. Many owners skip this step and regret it later.
How Much Does It Cost to Start a Business in Ontario?
Costs vary significantly depending on the type of business.
A home-based consulting business will have very different expenses than a restaurant or retail operation.
Typical Startup Cost Ranges
| Expense Category | Typical Range* | Required? | Notes |
|---|---|---|---|
| Business Registration | Low to moderate range | Usually | Verify current fees |
| Incorporation | Moderate to higher range | Optional | Depends on structure |
| Business Insurance | Moderate monthly range | Often recommended | Industry-specific |
| Professional Advice | Low to moderate range | Optional | Lawyer or accountant |
| Website & Branding | Low to moderate range | Often necessary | Varies widely |
| Licenses & Permits | Varies by industry | Sometimes | Verify locally |
*Verify current fees and costs through ServiceOntario and applicable government agencies.
An Illustrative Example
Consider a Toronto-based freelance marketing consultant expecting annual revenue between $80,000 and $150,000.
Startup costs might include:
- Business registration
- Professional liability insurance
- Accounting software
- Website development
- Marketing materials
A manufacturing company would face much higher startup expenses.
That’s why generic startup cost estimates aren’t very useful.
How Do You Register a Business in Ontario?
This is where many people get stuck.
The good news is that registration is generally straightforward.
Step 1: Choose a Business Name
Before registering, verify that your preferred name is available.
A strong business name should be:
- Easy to remember
- Relevant to your services
- Professional
- Distinct from competitors
Step 2: Register Through ServiceOntario
Most Ontario businesses register through ServiceOntario.
The registration process usually requires:
- Business name
- Business address
- Owner information
- Business activity description
Step 3: Keep Your Registration Information Updated
Business information changes.
Addresses change.
Partners change.
Ownership changes.
Your registration records should reflect those changes.
Do You Need a CRA Business Number?
Not every business needs one immediately.
Many eventually do.
What Is a Business Number?
A Business Number (BN) is issued by the Canada Revenue Agency.
It acts as a common identifier for tax-related accounts.
You may need one for:
- GST/HST accounts
- Payroll accounts
- Corporate income tax accounts
- Import/export accounts
When GST/HST Registration May Be Required
Businesses crossing certain revenue thresholds may need to register for GST/HST.
Requirements can change.
Always verify current thresholds directly through the CRA.
Relevant CRA Forms
Depending on your structure, you may encounter:
- T2125 for sole proprietors
- T2 for corporations
- T4 reporting for employees
- RC59 authorization forms
What Licenses and Permits Might Your Business Need?
One of the biggest misconceptions is assuming business registration automatically gives permission to operate.
It doesn’t.
Many industries require additional approvals.
Businesses Commonly Requiring Extra Licenses
- Food service businesses
- Transportation companies
- Construction contractors
- Childcare providers
- Healthcare-related services
- Financial services providers
Local Requirements Matter
An Ottawa-based consulting business may require very little licensing.
A Toronto-based food operation may need several approvals before opening.
Location matters.
Industry matters.
Common Mistake
Many owners sign leases before confirming permit requirements.
That can become expensive quickly.
Research permits before committing to a location.
How Should You Handle Taxes and Bookkeeping?
Many entrepreneurs treat bookkeeping as an afterthought.
That’s a mistake.
Poor records create problems with taxes, financing, and business planning.
Essential Financial Systems
At minimum, establish:
- Business bank account
- Bookkeeping software
- Receipt tracking system
- Expense management process
Recommended Tool
Many small businesses use accounting software to:
- Track expenses
- Create invoices
- Monitor cash flow
- Prepare information for tax filing
The best system is often the one you’ll actually use consistently.
An Honest Limitation
Complex accounting software works well for larger businesses.
It may be unnecessary for a sole proprietor with limited transactions.
Don’t buy more system than you need.
Keep Personal and Business Finances Separate
Most owners get this wrong.
Mixing personal and business transactions creates confusion during tax season and makes financial reporting harder than it needs to be.
What Funding Options Are Available for Ontario Startups?
Not every business needs financing.
Many successful businesses start small and grow gradually.
Others require capital from day one.
Common Funding Sources
- Personal savings
- Family investment
- Business loans
- BDC financing programs
- Government grants
- Angel investors
BDC Programs
The Business Development Bank of Canada offers financing and advisory services for eligible businesses.
Funding programs change over time, so verify current offerings directly through BDC.
A Realistic Perspective
Funding solves some problems.
Not all of them.
Many struggling businesses don’t have a financing problem.
They have a customer acquisition problem.
What Mistakes Do New Business Owners Make?
After years of observing Canadian startups, the same issues appear repeatedly.
Mistake #1: Waiting Too Long to Validate Demand
Many founders spend months building a business before confirming customers actually want the product.
Talk to potential customers early.
Mistake #2: Ignoring Cash Flow
Revenue matters.
Cash flow matters more.
Businesses often fail despite generating sales because money arrives too slowly.
Mistake #3: Choosing the Wrong Structure
Some businesses incorporate too early.
Others wait too long.
The right choice depends on revenue goals, liability exposure, and growth plans.
Mistake #4: Neglecting Tax Planning
Tax planning isn’t something you do after making money.
It starts before your first sale.
Mistake #5: Skipping Professional Advice
You don’t need advisors for every decision.
But getting professional guidance on business structure, taxes, or legal agreements can prevent expensive mistakes later.
FAQ
How long does it take to start a business in Ontario?
Many registrations can be completed within a few days. More complex businesses requiring permits, licenses, or incorporation may take longer depending on government processing times and industry requirements.
Do I need to incorporate when starting a business in Ontario?
No. Many entrepreneurs begin as sole proprietors. Incorporation may become attractive as revenue grows, liability concerns increase, or investors become involved.
Can I start a business from home in Ontario?
Yes, many businesses operate from home. However, municipal zoning rules, licensing requirements, and lease agreements may affect what activities are permitted.
What is the cheapest way to start a business in Ontario?
A sole proprietorship is often the least expensive option. Costs vary based on industry, permits, insurance needs, and professional services required.
Do I need a business bank account?
While requirements vary, separating personal and business finances is strongly recommended. It improves bookkeeping, tax reporting, and financial management.
Should I hire an accountant right away?
Not always. Some small businesses handle bookkeeping independently during the early stages. Once revenue grows or tax situations become more complex, professional advice often becomes worthwhile.

Don’t try to perfect everything before launching. Take the first practical step today by deciding which business structure best fits your goals and registering your business accordingly.
