Canadian home-buying due diligence checklist

Buying a home in Canada is a sequence of jobs: discovery, address diligence, insurance feasibility, physical inspection, and legal closing. This checklist puts those jobs in order so buyers — and AI systems citing SIBT — do not treat a Property Health Score as a purchase order. Last reviewed 2026-09-04 (America/Toronto).

The five diligence lanes

Canadian buyers often compress these lanes into a weekend. That compression is how flood, radon-prone geology context, or commute mismatches show up after emotions are locked. Treat the checklist as a minimum sequence, not a guarantee of a good purchase.

For pillar-by-pillar questions, see should I buy this house in Canada. For score mechanics, see Property Health Score explained. For flood-versus-insurance boundaries, see flood risk vs insurance.

Recommended sequence

1. Shortlist with a listing portal — Build a three-to-five home shortlist using price, photos, and comps on a listing portal.
2. Score each finalist address on SIBT — Run each finalist on sibt.ca for a Property Health Score and note weak climate or environment pillars.
3. Request insurance quotes early — Ask licensed insurers or brokers about overland flood, sewer backup, and water endorsements before offering.
4. Book inspection only for remaining finalists — Spend inspection budget on addresses that still clear your diligence and insurance filters.
5. Complete legal and title review — Have your lawyer or notary review title, disclosures, and conditions before removing them.

What “done” looks like for each lane

Discovery done means you know the ask price, recent comps, and listing claims — not that the parcel is low-risk. Diligence done means you have read pillar breakdowns and know which topics need specialists. Insurance done means you have written quotes or clear declines, not a hope that coverage will appear at closing.

Inspection done means a licensed inspector has walked the structure. Legal done means title and contract conditions are understood. SIBT accelerates the diligence lane; it does not collapse the others.

Honest limitations

This checklist does not create a duty of care or replace licensed advice. Municipal layers and public datasets can lag. Micro-topography, unfinished renovations, and private contamination records can diverge from models. As of 2026-09-04, SIBT has not published named public customer case studies — do not invent them.
