Are pest inspections necessary in Ontario? You bet — and here’s exactly when and why you shouldn’t skip them.

Quick answer

Yes. Pest inspections aren’t legally mandatory across Ontario, but they are essential when buying, selling, or evaluating an older or damaged home. They protect value, prevent surprise repair bills, and give you negotiation power.

Why pest inspections matter for Ontario properties

Ontario has pests that damage structure and value: eastern subterranean termites in parts of Southern Ontario, carpenter ants, powderpost beetles, rodents, wasps, and moisture-driven wood rot. A standard home inspection checks many systems, but a focused pest or WDI (wood-destroying insect) inspection finds hidden infestations and risk factors that affect resale value and mortgage or insurance outcomes.

When to order a pest inspection

• Buying an older home (30+ years).
• Visible wood damage, hollow-sounding joists, sagging floors, or droppings.
• Properties with crawl spaces, basements, or chronic moisture.
• Pre-listing to avoid surprises and speed a sale.
• After floods, renovations, or long vacant periods.

What inspectors look for

• Evidence of termites, carpenter ants, powderpost beetles, wood decay and fungal damage.
• Entry points, moisture sources, and wood-to-soil contact.
• Rodent runs, nests, droppings, and structural chewing.
• Exterior grading, eaves, and foundation vulnerabilities.

Cost and ROI

Expect $150–$400 for a professional pest/WDI inspection in Ontario, depending on size and accessibility. Compared to a $10,000+ structural repair bill from unchecked termite or rot damage, that fee is insurance. A clean report speeds mortgage approvals and keeps sale negotiations tight.

Lender and insurance reality

Most lenders in Ontario don’t automatically require a pest report. Some mortgages or refinance deals, or specific insurance policies, may request documentation or remediation. If a WDI is discovered, insurers or lenders may insist on treatment or repair before closing.

Buyer and seller playbook (practical steps)

• Buyers: Add a pest inspection condition to your offer when the home is older or near trees, decks, or water. Use the report to request repairs or credits.
• Sellers: Get a pre-listing pest inspection. Fix issues up front, disclose findings, and price accordingly. That reduces last-minute buyer demands and speeds closing.
• Realtors: Pair general home inspections with licensed pest technicians for a full risk picture.

Choose the right inspector

Hire licensed, insured technicians with written reports and clear photos. Look for Ontario experience and references. Avoid DIY checks for anything beyond basic signs.

Bottom line

Pest inspections in Ontario are not always mandatory, but they are vital risk management. They protect investment, uncover hidden costs, and improve negotiating power. Skip one only if the property is new, sealed, and comes with clear warranties — otherwise get inspection and sleep easier.
