Home Inspection Checklist Canada 2026: What a Good Inspector Actually Checks

Once an offer is accepted, the home inspection is one of the few points in a Canadian real estate transaction where an independent professional actually looks at the property before you’re legally committed to buying it. A thorough inspector more than earns a $400-$600 fee; a rushed one can leave you facing a $30,000 repair bill six months after closing. From our experience, buyers also benefit from knowing what to look for themselves before booking the full inspection-and from understanding which findings are genuine deal-breakers versus which ones are simply the normal wear that comes with older Canadian housing stock. This guide covers all of that in plain terms.

What a Home Inspector Is (and Isn’t) Responsible For

Home inspectors in Canada are not all regulated equally. As of 2026, British Columbia, Alberta, Ontario, and Nova Scotia have mandatory licensing requirements for home inspectors. Quebec, Manitoba, Saskatchewan, and the Atlantic provinces outside Nova Scotia have varying levels of oversight — some have voluntary associations, some have almost none. Before you book anyone, check whether your province requires a licence and verify the inspector holds one.

A qualified inspector in a regulated province will typically carry errors and omissions (E&O) insurance. That matters because if they miss something material and you can document it, you have a path to recourse. Ask directly: “Are you licensed in this province and do you carry E&O insurance?” If they hesitate, keep looking.

What an inspector does: a visual, non-invasive assessment of accessible systems and components. They are not opening walls, running appliances for extended periods, or providing a structural engineer’s report. They’re giving you a professional snapshot of visible conditions on the day of the inspection. That’s valuable — but it has limits.

What they don’t do: move furniture, lift carpets they can’t lift safely, assess anything behind drywall, test for mould (though they may note conditions that suggest mould risk), or give you a renovation quote. For those, you need specialists.

Pre-Inspection: What You Can Check Yourself First

Before spending $400–$600 on a professional, a basic walkthrough of your own can help you decide whether to proceed and flag specific concerns for your inspector. This isn’t about replacing the professional — it’s about going in informed.

Outside the house

• Walk the perimeter and look at the grading. Does the ground slope toward the foundation or away from it? Water that pools against a foundation is a slow disaster.
• Check the roof from the ground with binoculars if you have them. Missing shingles, visible sagging, or significant moss growth are all worth noting.
• Look at the eavestroughs. Are they pulling away from the fascia? Sagging in the middle? Downspouts that dump water right at the foundation?
• Inspect the driveway and walkways for major cracking or heaving.

Inside the house

• Turn on every tap and flush every toilet. Low water pressure or slow drainage tells you something.
• Look at ceilings for water stains — yellowish rings or bubbling paint are signs of past or active leaks.
• Open every door and window. If interior doors stick badly or won’t latch, that can signal foundation movement or settling beyond normal.
• Check the electrical panel. If you see fuses (not breakers), that’s an older system worth flagging.
• Go into the basement and look for white mineral deposits (efflorescence) on the walls — a sign of water infiltration over time.

If your walkthrough raises serious concerns, you may decide to bring in a specialist (structural engineer, plumber) before even booking a general inspection. More commonly, you’ll have a targeted list of questions ready for your inspector.

The 47-Point Home Inspection Checklist: What Gets Checked

A thorough Canadian home inspection covers seven main systems. Here’s what should be on the list.

Roofing (6 points)

1. Shingle condition and estimated remaining life
2. Flashing at chimneys, vents, and valleys
3. Eavestroughs and downspouts condition and drainage direction
4. Soffits and fascia condition
5. Attic ventilation (assessed from the attic hatch if accessible)
6. Evidence of ice damming or prior water damage at eaves

Structure and Foundation (8 points)

7. Foundation wall type (poured concrete, block, stone)
8. Visible cracks — horizontal cracks in block foundations are a serious concern; vertical hairline cracks in poured concrete are common and often minor
9. Evidence of water infiltration (staining, efflorescence, dampness)
10. Floor framing in basement — signs of rot, pest damage, or unauthorized modifications
11. Grading and drainage around the exterior foundation
12. Visible structural posts and beams — rot, improper connections, missing supports
13. Window wells and their drainage
14. Crawl space conditions if applicable — vapour barrier, ventilation, moisture

Electrical (7 points)

15. Panel type, amperage, and age (60-amp panels are generally inadequate for modern homes; 100-amp minimum, 200-amp preferred)
16. Evidence of knob-and-tube or aluminum wiring
17. GFCI protection in kitchens, bathrooms, and exterior outlets
18. Proper grounding
19. Visible wiring condition in basement and accessible areas
20. Outlet function (inspectors use a plug-in tester)
21. Smoke and CO detector locations noted

Plumbing (7 points)

22. Supply pipe material (copper, PEX, galvanized — galvanized is at end of life if the home is older)
23. Drain pipe material (ABS, cast iron, Orangeburg — Orangeburg is a red flag)
24. Water pressure and flow at multiple fixtures
25. Water heater age, type, and condition (most have a 10–15 year lifespan)
26. Visible evidence of leaks under sinks, around toilets, at the water meter
27. Sump pump presence and condition in basement
28. Main shutoff valve location and operation

Heating and Cooling (7 points)

29. Furnace age, type, and condition (gas furnaces typically last 20–25 years)
30. Heat exchanger visible condition (cracks here are a carbon monoxide risk)
31. Ductwork condition and distribution
32. Air conditioner (if present) — age, condition, and whether it runs
33. Flue and venting for combustion appliances
34. Fireplace and chimney visible condition, damper operation
35. Thermostat operation

Insulation and Ventilation (4 points)

36. Attic insulation depth and type (older vermiculite insulation may contain asbestos — flag for testing)
37. Vapour barrier presence in attic and basement
38. Bathroom and kitchen exhaust venting to exterior (not just into the attic)
39. Visible insulation gaps at rim joists and accessible exterior walls

Interior and General (8 points)

40. Windows — operation, seals (foggy double-pane = failed seal), condition
41. Doors — operation, weatherstripping, locks
42. Floors — visible settlement, soft spots, damage
43. Walls and ceilings — cracks, water stains, evidence of patching
44. Garage — fire separation from living space, vehicle door operation, CO detector
45. Deck or porch — structural condition, ledger board attachment, guardrail height compliance
46. Steps — rise-and-run safety, condition
47. Evidence of pest activity (carpenter ants, mice, termites in southern Ontario)

Red Flags That Can Kill Deals (or Should)

Not every inspection finding is equal. Here’s a practical breakdown.

The findings that carry the most weight in renegotiations are ones that affect safety, insurability, or involve major systems. Cosmetic issues — dated fixtures, worn carpet, chipped paint — are not leverage in a professional inspection negotiation. Focus on the structural and mechanical.

How to Use the Inspection Report Strategically

Once you have the report (typically delivered within 24–48 hours), read it fully before you call your realtor. Many buyers skim to the summary and miss important detail buried in the body of the report. Flag anything the inspector marked as “major concern” or “safety issue” — those are the items that move a negotiation.

Your options after an inspection that reveals significant issues are generally: renegotiate the purchase price, ask the seller to remediate specific items before closing, ask for a credit at closing in lieu of repairs, or walk away if your offer included an inspection condition. In most Canadian markets in 2026, the window for a standard inspection condition is five business days, though this varies by province and offer terms.

For home purchase resources including mortgage calculators and neighbourhood guides, NorthMarkets has additional tools to help you through the buying process. If you’re working through financing at the same time, understanding how the stress test threshold affects your qualification is worth reviewing alongside your inspection timeline.

If the inspection reveals something serious enough that you want a specialist, ask your inspector directly for a referral. They work alongside structural engineers, plumbers, and electricians regularly and often have contacts they trust. That’s worth more than a random Google search under time pressure.

Honest Takeaway: When This Process Works, and When It Doesn’t

When a thorough home inspection is clearly worth it: Any resale home, any age, any price point. Period. The inspection fee is a rounding error relative to the transaction. Skipping it to make an offer “cleaner” in a competitive market is a risk worth understanding very carefully before you take it. If you waive inspection, you’re not saving money — you’re assuming unlimited liability for whatever is behind those walls.

When the standard inspection has limits: Pre-construction homes have different processes (PDI — pre-delivery inspection — and Tarion or provincial warranty coverage in Ontario). Condo purchases require reviewing the status certificate in addition to any inspection. Very old homes (pre-1950) in certain regions may warrant specialist add-ons: oil tank sweep, asbestos testing, sewer scope, or full structural assessment beyond what a general inspector covers.

When to push back on your inspector: If the report arrives and every finding is logged as “monitor” with no clear severity ranking, that’s a sign the inspector may be conflict-averse rather than thorough. A good report will clearly distinguish minor maintenance items from genuine concerns. If yours doesn’t, ask directly: “Which three findings here concern you most, and why?”

When DIY pre-checks are not enough: They’re never a replacement for the professional inspection — only a preparation tool. Use them to go in smarter, not to avoid the cost.

A home inspection done properly gives you one of the few honest moments in a real estate transaction: an independent professional telling you what they actually see, without a financial stake in whether the deal closes. Use that window well.
