Home Inspections in Ontario: What They Cover, What They Cost, When to Skip
A home inspection is a few hours and a few hundred dollars standing between you and the most expensive surprises a house can hide. Here is what an inspector actually does, what the report can and cannot tell you, and how to handle the inspection when the market is pushing you to waive it.
What an inspection is — and what it isn't
A home inspection is a visual, non-invasive examination of a house's major systems by a trained inspector, usually taking two to three hours, with a written report delivered the same or next day. It is not a pass-or-fail test, not a building-code audit, and not a guarantee. The inspector cannot open walls, so the job is evidence-reading: stains that suggest a past leak, a furnace whose age and service tags tell a story, grading that pushes water toward the foundation instead of away from it.
In Ontario, home inspectors are not provincially licensed, which makes track record and association membership (the Ontario Association of Home Inspectors is the main professional body) worth checking before you book. Your agent will usually have names; the good ones are booked by reputation and stay booked.
What gets inspected
- Structure and exterior — foundation walls for cracks and water entry, roof condition and approximate age, grading, decks, and the state of windows and doors.
- Electrical — panel size and type (100-amp service is the common modern baseline), visible wiring concerns such as knob-and-tube or aluminum branch wiring, which insurers care about too.
- Plumbing — supply and drain materials, water pressure, signs of past leaks, and older materials like galvanized supply lines or kitec in some condo-era builds.
- Heating and cooling — furnace and AC age, service history, and heat distribution; a mid-life furnace is a budgeting item, an end-of-life one is a negotiation item.
- Interior and attic — insulation depth, ventilation, moisture signs in bathrooms and basements, and the small things (sticking doors, sloped floors) that point at bigger ones.
What a general inspection does not cover: septic systems, wells, pools, wood-burning appliances (those need a WETT inspection), and anything behind finished walls. Rural properties often need two or three specialist inspections on top of the general one — budget for that when you write the offer, not after.
What it costs, and who pays
Expect a few hundred dollars for a typical house in the GTA — commonly in the $400–$600 range depending on size and age — paid by the buyer, at the time of the inspection. Condo inspections, where they happen, cost less because the building's major systems belong to the corporation. Treat the fee as part of your closing costs planning rather than an optional extra: it is the cheapest information in the entire transaction.
The condition, the pre-inspection, and the waiver
The traditional route is an inspection condition in your offer: a few business days to bring in an inspector after acceptance, with the right to walk away or renegotiate if the report surfaces something serious. How that condition is worded matters — our guide to firm vs. conditional offers explains the trade you're making when you include it or drop it.
In competitive situations, buyers increasingly pay for a pre-offer inspection — inspecting during the showing window, before offers are due, so they can bid firm with the information in hand. The risk is real: you pay for inspections on houses you may not win. Sellers sometimes commission their own pre-listing inspection and share the report; read it, but remember who paid for it, and note that relying on it doesn't give you the same relationship with the inspector if something is missed.
Skipping the inspection entirely is a legitimate choice in exactly two situations: a new build still covered by Tarion warranty (where your pre-delivery inspection is the structured version of the same idea), and a genuine teardown or gut-renovation purchase where the systems you'd inspect are already in your demolition budget. For everything else, waiving is not confidence — it's a price you're choosing to pay for the house, added on top of the price on paper. The full sequence, so you can see where the inspection sits, is in our guide to the full buying process in Ontario.
Reading the report like an owner
Every report on an older Ontario home lists dozens of items; most are maintenance notes, not defects. Sort what you read into three piles: safety and water (electrical hazards, active leaks, foundation water entry — these matter now), big-ticket lifespans (roof, furnace, windows — these matter to your budget over five years), and cosmetics (everything else). A good inspection doesn't kill deals; it prices them honestly.
