A home-based business is how most Ontario founders actually start — cheap, fast, and low-risk. The catch is that running a business from your house triggers rules most people don't know exist: zoning, insurance, tax, and sometimes your condo board. Here is how to start a home-based business in Ontario in 2026, properly.
Can You Legally Run a Business from Home?
Usually yes — but it depends on your municipality's zoning by-law, your property type (rental, condo, freehold), and the type of business. Toronto, for example, allows most "home occupations" if the business doesn't have walk-in clients, employees coming to the home, outdoor storage, or signage. Check your city's home occupation rules before you register.
Register Like Any Other Ontario Business
Being home-based doesn't change the registration process. You still register a sole proprietorship ($60) or incorporate ($300) through the Ontario Business Registry. You still get a BN, still register for HST at $30K, still keep clean books.
Insurance Is the Thing Most People Miss
Your home insurance almost certainly excludes business activities. If a client trips in your driveway, or business inventory burns in a fire, your home policy won't cover it. Options:
- Home business endorsement — cheap add-on if risk is low
- Standalone commercial general liability — $500-$1,500/year typical
- Professional liability / E&O — if you give advice or services
Home Office Tax Deductions
You can deduct the business-use percentage of home expenses: rent/mortgage interest, utilities, property tax, internet, maintenance. The percentage is based on the square footage of your workspace divided by total home square footage. Keep receipts, keep a floor plan, and don't claim more space than you actually use — CRA audits do happen and this is a common flag.
Operating From Home Without the Chaos
The biggest operational risk of a home business is client communication leaking into personal life. Use a dedicated business phone number (Google Voice, a VoIP line, or a CRM with built-in messaging), a business email, and a CRM like Threecus that keeps inquiries, bookings, and invoices in one place so your kitchen table doesn't become a helpdesk.
