How Much Does It Cost to Start a Business in Ontario?

5 min read

Starting a business in Ontario costs between $60 and $3,000 depending on structure, insurance, and licensing. Here is the real line-by-line breakdown.

Starting a business in Ontario costs between $60 and $3,000 in the first year. A sole proprietorship is $60, an Ontario corporation is $300, and the rest is insurance, licensing, and banking. Here is the exact breakdown in 2026.

How much does registration cost?

  • Sole proprietorship (5-year term): $60
  • General partnership (5-year term): $60
  • Ontario corporation: $300 (online) + Articles of Incorporation
  • Federal corporation: $200 + extra-provincial Ontario registration (~$330)
  • NUANS name search (for corporations): $13-$26
  • CRA Business Number: free

How much is business insurance in Ontario?

Basic commercial general liability for a small business runs $500 to $1,500 per year. Professional liability (E&O) for consultants and service providers adds another $400 to $1,200. Trades and high-risk industries pay more. A home business endorsement on your existing home policy can start as low as $100/year if your risk is very low.

Do I have to pay for a licence?

Only if your municipality or industry requires one. Most generic consulting, design, and online businesses don't need a municipal licence. Regulated industries (food, personal services, contractors, short-term rentals) do. Toronto licence fees range from $55 to $600. See our Toronto business licence guide.

What are the ongoing costs?

  • Annual return (corporations): $12-$30
  • Bookkeeping software: $0 (Wave) to $360/year (QuickBooks)
  • CRM for client management: $0-$600/year — Threecus offers a free tier
  • HST remittance: neutral if you charge it, but adds admin time
  • Accountant for corporate tax return: $800-$2,500/year

What should I actually budget?

For a sole proprietorship with basic insurance and no municipal licence, budget $700 to $1,500 for year one. For a corporation with insurance and an accountant, budget $2,500 to $4,000. Anything above that is usually inventory, equipment, or a physical space.
