A home inspection report is one of the most misused documents in the Canadian real estate process. Buyers use it as a blunt instrument to demand price reductions on normal maintenance items. Sellers use it as a source of anxiety. Both miss the point. A good inspection report is a detailed condition assessment of a building — useful for making informed decisions about a purchase or a renovation sequence, not a pass/fail test.
What a home inspector actually does
A Canadian home inspector conducts a visual inspection of accessible and observable components of the property. This typically takes two to four hours for an average-sized house. They examine the structure, exterior, roofing, electrical, plumbing, heating and cooling, insulation and ventilation, interior finishes, and built-in appliances. What they do not do: they do not move furniture, lift flooring, remove wall panels, test for mould or asbestos, or operate systems that are shut off. Many significant defects — water intrusion behind drywall, foundation cracks behind insulation, knob and tube wiring behind finished ceilings — are not visible to a surface-level examination.
The report format
Canadian home inspection reports vary in format but most use a condition-by-condition structure with ratings — typically satisfactory, marginal, defective, or safety concern — and narrative explanations. A good report includes photographs and distinguishes between items requiring immediate attention, items to monitor, and normal maintenance. A report for a typical Canadian home might contain 50–150 individual observations. The useful exercise is separating the significant findings from the routine ones.
What actually matters: the five major categories
Foundation and structure. Foundation cracks, signs of settling, wood rot in structural members, or evidence of moisture intrusion below grade are the highest-priority findings. Not all foundation cracks are equal — hairline cracks in poured concrete are normal; horizontal cracks in block foundations or significant diagonal cracks in poured walls warrant a structural engineer's evaluation costing $500–$700.
Roof condition. Inspectors estimate remaining useful life of the roofing material and identify signs of current or past leakage. A roof with five to seven years of life remaining is a near-term capital expense of $8,000–$20,000 for a typical Canadian home.
Electrical panel and wiring. Federal Pacific Stab-Lok panels are a recognized fire hazard — replacement runs $2,500–$5,000 and is often required by insurers. Knob and tube wiring in homes built before 1950 cannot be buried in insulation and often requires updating before adding circuits. Aluminum wiring common in 1960s–70s Canadian homes requires either replacement or remediation by a licensed electrician.
Plumbing system. Inspectors check water pressure, visible supply and drain pipes, water heater age (typical useful life 10–15 years for a tank heater), and signs of active leaks. Polybutylene (Poly-B) piping, installed in many Canadian homes between 1978 and 1995, is known to fail and is often flagged by insurers as a replacement requirement.
HVAC condition and age. A furnace over 20 years old is at or near end of life; budget for replacement ($4,000–$8,000) regardless of current function. A cracked heat exchanger in a furnace is a carbon monoxide risk and requires immediate replacement.
Using the report in negotiations
Not every finding warrants a price reduction. Normal maintenance items are part of buying any existing home and are typically priced into the market. Effective negotiation: focus on two to four significant findings, get written quotes from contractors for the specific remediation, and request either a price reduction or a credit equivalent to the actual repair cost.
When to get follow-up specialists
Conditions warranting follow-up include: any significant foundation finding (structural engineer), active moisture or mould evidence (industrial hygienist), knob and tube or aluminum wiring (electrician quote), Poly-B plumbing (plumber quote), and any indication of environmental concerns in an older home (asbestos test, radon test). These follow-up evaluations typically cost $200–$700 and convert a vague concern into a specific, priced action item.
