In short
It costs far less than most of the problems it can uncover.
Most buyers make the offer conditional on a satisfactory inspection. If you go firm, consider a pre-offer inspection.
How it works in Ontario
A home inspection is a visual review of a home's main systems and structure: roof, foundation, drainage, heating and cooling, plumbing, electrical, windows, attic and insulation. You get a written report, often with photos.
Most buyers either make the offer conditional on a satisfactory inspection or, in competitive situations, book a pre-offer inspection before submitting a firm offer.
An inspection is not mandatory in Ontario. It is the buyer's choice and the buyer usually pays for it.
For a condo, the inspection usually covers just the unit, while the building's common elements are looked at through the status certificate and reserve fund study.
Are home inspectors licensed in Ontario?
No, not as of 2026. Ontario passed the Home Inspection Act, 2017, which would require inspectors to be licensed, but the government has not brought it into force.
That means anyone can call themselves a home inspector. Ask about training, membership in a professional association, errors and omissions insurance, and to see a sample report before you book.
Some buyers also ask whether the inspector carries insurance and how the inspection contract limits the inspector's liability. Read that contract before the inspection starts.
What an inspection doesn't cover
Inspectors look at what they can see and safely reach. They don't open walls, move furniture or test every component, and they can't predict how long a furnace or roof will last.
If the report flags something specialized, such as a sewer line, a wood stove, knob-and-tube wiring or possible asbestos, you may need a specialist to look closer.
Using the report
An inspection condition gives you time to understand what you're buying. Depending on what's found, buyers may go ahead, try to renegotiate, or let the condition lapse.
Read the summary and the full report, and attend the inspection if you can. It's the best way to learn where the shut-offs are and what to budget for.

What does a home inspection include?
A home inspection is a visual review of the home's structure and major systems. That typically includes the roof, foundation, drainage, heating and cooling, plumbing, electrical, attic and insulation. Inspectors don't open walls, so hidden problems may need a specialist.
What is a pre-offer inspection?
A pre-offer inspection is an inspection done before you submit your offer, usually so you can make a firm offer with no inspection condition. The seller has to allow access. It costs you the fee even if you don't win the house, so weigh that before booking.
