Electrical system Safety Assessment of Aluminum Wiring for Insurance Purposes in Ontario
Aluminum wiring is one of the most common reasons Ontario homeowners get flagged by insurance companies. If your home was built between 1965 and the late 1970s, there is a strong chance aluminum branch wiring is present — and insurers often require a Licensed Electrical Contractor (LEC) to perform a formal Electrical Safety Assessment before issuing or renewing a policy.
This assessment ensures the home meets Ontario electrical safety standards and provides the documentation insurers need to approve coverage.
Why Insurance Companies Care About Aluminum Wiring
Aluminum wiring itself is not unsafe — the risk comes from connections. Aluminum expands, contracts, and oxidizes more than copper, which can lead to:
Loose terminations
Overheating
Arcing
Increased fire risk
Because of this, many Ontario insurers:
Add surcharges
Require an electrical inspection
Demand remediation
Refuse coverage until documentation is provided
A proper assessment by a Licensed Electrical Contractor is the only way to satisfy insurance requirements.

What is an Electrical System Safety Assessment
An Electrical System Safety Assessment is a review of your home's electrical wiring and/or devices to identify potential electrical hazards that could lead to a fire and/or shock. An LEC may use an Electrical System Safety Assessment Checklist when evaluating a home’s electrical system.
1. Identification of Aluminum Branch Circuits
Homes built between 1965–1976 are inspected for aluminum conductors at:
Receptacles
Switches
Light fixtures
Junction boxes
Panel terminations
2. Inspection of All Connection Points
The electrician checks for:
Loose or overheated terminations
Discoloration or melting
Oxidation
Incorrect CU‑only devices
3. Panel Termination Evaluation
Panel lugs and breakers are inspected for:
Loose aluminum conductors
Overheating
Improper torque
Corrosion
4. Warning Signs of Unsafe Aluminum Wiring
Common indicators include:
Warm outlets
Flickering lights
Burning smell
Intermittent power
5. Device Compatibility Verification
Aluminum wiring must terminate on:
CO/ALR‑rated devices
Approved connectors
6. Remediation Options
Insurers accept two solutions:
(1) Copper Pigtailing (Most Common)
A short copper conductor is spliced to each aluminum wire using approved connectors.
Full Rewire (Rare)
(2) Complete replacement of aluminum wiring.
7. ESA Permit & Certificate of Acceptance
Insurance companies require proof that:
The work was done under an ESA permit
A Certificate of Acceptance was issued
