Does Your Commercial Insurance in Ontario Require an Annual Electrical Inspection?

Does Your Commercial Insurance in Ontario Require an Annual Electrical Inspection?

If you manage or own a commercial property in Ontario, your insurance carrier may already expect you to have a documented electrical inspection program in place.

Many facility owners find this out at renewal — when their broker raises questions about preventive maintenance documentation, or when a claim is challenged because inspections were not on record.

Understanding what your insurer actually expects — and when — puts you in a much stronger position.

Key Takeaways

• Many Ontario commercial insurers are requiring or strongly recommending annual infrared electrical inspections as a condition of coverage
• Electrical fires remain one of the leading causes of large commercial property losses in Canada
• Facilities without documented inspection programs may face higher premiums, coverage limitations, or claims disputes
• Infrared thermography is the inspection method most widely recognized by underwriters for electrical risk documentation
• Annual inspections are the standard for most commercial properties, with higher-risk facilities requiring more frequent scans

Why Insurers Are Focusing on Electrical Risk

Electrical fires and equipment failures are among the most costly claims in the commercial property insurance market.

Aging electrical infrastructure, increasing energy demand, and deferred maintenance have all contributed to a rise in electrically-related losses across Ontario commercial and industrial properties.

Insurers have responded by asking harder questions during the underwriting and renewal process:

• When was the last documented electrical inspection?
• Are high-risk electrical assets inspected under load?
• Is there a formal preventive maintenance program in place?
• Can you produce inspection reports from the past 12 months?

For facilities that cannot answer these questions with documentation, underwriters have more leverage — and they are using it.

What Insurers Are Actually Asking For

Insurance carriers in Ontario are not uniformly mandating infrared inspections across all policy types. Requirements vary by insurer, policy type, industry, and risk profile.

However, a clear pattern has emerged across the commercial property market:

• Higher-risk facilities — manufacturing, heavy industry, multi-tenant commercial — face the most scrutiny
• Insurers increasingly ask for thermographic inspection reports as part of the renewal submission
• Some carriers include inspection requirements as policy conditions, not just recommendations
• Facilities with documented programs tend to have smoother renewals and fewer adverse underwriting decisions

The practical reality is that even where infrared inspections are not formally required, the absence of documentation is increasingly being used to justify rate increases or coverage restrictions.

What Type of Inspection Do Insurers Recognize?

Not all electrical inspections satisfy insurer expectations equally.

A visual walkthrough or a standard ESA inspection addresses code compliance but does not detect the developing thermal faults that infrared thermography identifies.

Underwriters are looking for thermographic inspection reports specifically — because thermal imaging detects issues under load, before failure occurs, and produces documented evidence that a facility is actively managing electrical risk.

Key elements insurers expect in a compliant thermographic report include:

• Asset identification and location
• Thermal and visual image pairing
• Temperature differential measurements
• Severity classification of findings
• Repair recommendations
• Evidence of follow-up corrective action

A report that checks these boxes demonstrates proactive risk management — which is exactly what underwriters want to see.

How Often Should Inspections Be Conducted?

For most commercial properties in Ontario, an annual infrared inspection is the recognized standard.

Higher-risk environments may require more frequent inspections:

• Semi-annual inspections for manufacturing, heavy industrial, or high-load facilities
• Post-installation scans following major electrical upgrades or new equipment
• Follow-up scans after corrective repairs have been completed

Consistency is critical. A single inspection provides a point-in-time snapshot. An annual program provides the trend documentation that insurers use to assess whether a facility is genuinely committed to risk management.

The Renewal Conversation

If your policy is coming up for renewal and you do not have a documented inspection program, now is the time to act.

Brokers increasingly advise clients to have current thermographic inspection reports available before the renewal submission. Facilities that proactively provide this documentation are in a stronger negotiating position than those responding to underwriter requests.

Insurers do not automatically reduce premiums for having inspections on record — but facilities with documented programs are demonstrably less likely to experience adverse renewal conditions, coverage restrictions, or claims disputes tied to deferred maintenance.

Frequently Asked Questions

Is an infrared electrical inspection legally required for commercial properties in Ontario?

There is no universal legal requirement mandating infrared inspections for all commercial properties in Ontario. However, the Electrical Safety Authority (ESA) and Ontario Fire Code recognize thermographic inspections as a best practice, and many insurance carriers are making them a condition of coverage for higher-risk properties. The practical impact is that facilities without documented inspections are increasingly at a disadvantage during underwriting and claims review.

What happens if I have an electrical fire and no inspection records?

The absence of documented preventive maintenance can complicate a claim. Insurers may challenge whether the loss was foreseeable and whether reasonable steps were taken to prevent it. While every claim is assessed on its specific facts, having documented thermographic inspection records — including identified findings and corrective actions — provides a much stronger position.

Do all types of commercial properties need annual inspections?

Annual inspections are the recognized standard for most commercial properties. Higher-risk facilities — manufacturing plants, heavy industrial operations, multi-tenant buildings with high electrical loads — may require semi-annual inspections. Lower-risk, lower-load properties may be adequately served by a consistent annual program. IRIS PDM can help assess the right frequency for your facility type.

Will having an infrared inspection reduce my insurance premium?

Insurance carriers do not automatically guarantee premium reductions for thermographic inspections. However, documented preventive programs can help stabilize premiums, reduce underwriting concerns, and strengthen your position during renewal negotiations. The financial benefit varies by insurer, policy type, and risk profile.

How do I know if my policy already requires infrared inspections?

Review your policy conditions and speak with your broker. Some carriers include inspection requirements explicitly in policy language. Others raise the issue informally during renewal. If your policy is silent on the matter, your broker can advise whether your insurer has expectations that are not formally documented in the policy wording.
