Home Inspections in Toronto: What Is Covered, What Is Not, and How to Use One in a Bidding War

A home inspection is a visual, non-invasive examination of a house by a generalist, on one day, for a fee of a few hundred dollars. It is not a guarantee, it is not a code inspection, and in Toronto it often has to happen before you offer rather than after. Knowing what it can and cannot tell you — and what Toronto’s 100-year-old housing stock tends to hide — is how you make it worth the money.

1. 1.What an inspection is, and is not

   A general home inspection follows a standard of practice (OAHI/CAHPI or InterNACHI in Ontario): the inspector examines the readily accessible, visible components of the house — roof from the ground or ladder, exterior, structure as visible, electrical panel and visible wiring, plumbing fixtures and visible supply and drain lines, heating and cooling equipment, insulation and ventilation as visible, interior surfaces, windows and doors — and reports on their condition and on safety issues. 2–4 hours on site for a Toronto house; a written report with photos the same day or next.

   • Not covered: anything behind finished walls or under carpet, inside sealed systems, or underground (sewer lateral, oil tank, foundation drainage); code compliance; pests; mould testing; appraisal; environmental testing (radon, asbestos, lead); pool and spa equipment unless added; chimneys inside the flue; and whether the basement apartment is legal.
   • Add-on services exist for most of these: sewer-scope camera ($250–$400), thermal imaging (often included), WETT inspection of a wood stove or fireplace ($150–$300), radon test (long-term, 90 days), asbestos sampling, mould air test. In Toronto, a sewer scope on any house built before 1960 is money well spent.
   • Condo inspections are shorter and cheaper ($300–$450): the unit’s systems and finishes, the in-suite HVAC, windows and balcony; the building itself is assessed through the status certificate and reserve fund study, not the inspection.

2. 2.Why Ontario inspectors are not licensed, and how to choose one

   Ontario passed the Home Inspection Act, 2017 to license the profession, but the Act has never been proclaimed into force. As of 2026 anyone may call themselves a home inspector. The quality signals are voluntary: the Registered Home Inspector (RHI) designation from the Ontario Association of Home Inspectors, CAHPI’s national certification, or InterNACHI certification; errors-and-omissions and general liability insurance; years in the Toronto market specifically; and a sample report you can read before you book.

   • Ask: how many Toronto houses of this age and type have you inspected? Do you carry E&O insurance? Will you walk the roof, open the panel and run every fixture? Is thermal imaging included? Can I attend?
   • Attend. The two hours walking with the inspector are worth more than the report; it is where you learn how the house works and which findings are routine versus serious.
   • Inspectors recommended by the listing agent are a conflict of interest; use your own.

3. 3.What Toronto houses hide: the defects by era

   • Pre-1950 (most of the central 416 — the Annex, Riverdale, Leslieville, the Junction, Roncesvalles, the Beaches): knob-and-tube wiring (insurers require removal or an ESA certificate; $8,000–$25,000 to replace), galvanized steel supply plumbing (low pressure, $5,000–$15,000 to repipe), clay sewer laterals (root intrusion; $8,000–$20,000 to replace), rubble or brick foundations with moisture, no insulation in walls, lead water service from the street (City of Toronto has a replacement program for the public side), and balloon framing.
   • 1950s–1970s (East York, North York, Scarborough, Etobicoke bungalows and sidesplits): 60-amp services, aluminum branch wiring in houses built roughly 1965–1976 (insurable with proper connectors; $3,000–$10,000 to remediate), asbestos in vermiculite insulation, floor tiles, pipe wrap and duct tape (leave undisturbed or abate), UFFI foam insulation (1975–1978), buried oil tanks from converted furnaces, and original windows.
   • 1980s–2000s (suburban 905 subdivisions, early condo towers): Kitec plumbing (1995–2007; grey/orange PEX with brass fittings that fail — insurers and lenders care; $5,000–$15,000 to replace in a house, often a building-wide program in condos), poly-B plumbing (less common in Ontario), early window-wall condo envelopes, and settlement cracks in poured foundations.
   • Any era: roof age and layers (a third layer is a code violation), grading sloping toward the house, downspouts discharging at the foundation, basement moisture staining, undersized or dead sump pumps, improperly vented bathroom fans into the attic, and unpermitted basement apartments and rear additions.

4. 4.Pre-offer inspections: how Toronto actually works

   On a competitive freehold listing with an offer date, a conditional-on-inspection offer loses to firm offers almost every time. The Toronto workaround is the pre-offer inspection: you book an inspector during the showing window — often the listing agent arranges a block where several buyers’ inspectors come through — and you offer firm with the knowledge in hand. It costs you the inspection fee whether or not you win; serious buyers spend $450–$800 two or three times before they buy a house.

   • Sellers sometimes provide a pre-listing inspection report. Read it; do not rely on it — the inspector worked for the seller, the report may be weeks old, and you cannot sue an inspector you did not hire.
   • Where the seller allows only a short window, prioritize: panel, basement, roof, visible plumbing, and a sewer scope if pre-1960. Skip the cosmetic walk.
   • If you keep an inspection condition, make it short (2–3 business days) and decide beforehand what finding would make you walk, renegotiate or proceed.

5. 5.Reading the report

   A good report separates safety issues, major defects, items at the end of their service life, and maintenance items, with photos and rough cost ranges or a recommendation to get a specialist quote. Expect 40–80 pages for a Toronto house; most of it is routine. The three questions:

   • What costs more than $5,000 in the next two years? Roof, furnace, electrical service, repiping, foundation water, sewer lateral, windows.
   • What affects insurability or financing? Knob-and-tube, aluminum wiring without remediation, 60-amp service, Kitec, buried oil tank, wood stove without WETT, a roof past 20 years — insurers may refuse or surcharge, and the lender needs insurance to fund.
   • What is a safety issue today? Missing GFCIs, double-tapped breakers, open junction boxes, no CO or smoke alarms, loose railings, a furnace venting issue.

   Nothing in the report is a pass or fail. It is information for a negotiation (a price reduction or a seller repair via a Form 120 amendment), a decision to proceed, or a decision to walk.

6. 6.New homes and pre-construction

   A new house or condo carries the Tarion warranty — one year on workmanship and materials, two on water penetration and major systems, seven on major structural defects — and a Pre-Delivery Inspection (PDI) with the builder before you take possession. Bring your own inspector to the PDI ($300–$500): the builder’s representative lists what you point out, and anything not on the PDI form is harder to claim later. File the 30-day and first-year Tarion forms on time; the deadlines are strict.

7. 7.What happens when the inspector misses something

   Inspection agreements limit the inspector’s liability, commonly to the fee paid, and courts have generally enforced those limits in Ontario where the clause was clear and the buyer signed it. Recovery for a missed defect is therefore rare and small; the realistic remedies are against a seller who concealed a known latent defect (the common-law claim) or, for new homes, Tarion. Treat the inspection as risk reduction, not insurance — and buy the add-on tests (sewer scope, WETT, asbestos sampling) where the house’s era makes the risk real.
