The sensible first step is an assessment, not an automatic replacement quote. Aluminum wiring is permitted under the Ontario Electrical Safety Code, but connections, devices and installation condition matter. Great Lakes Electric offers wiring upgrade and aluminum wiring replacement services for Sarnia and surrounding Lambton County properties.

Does my Sarnia home have aluminum wiring?
Aluminum branch-circuit wiring can be found in some homes built or wired from the mid-1960s through the late 1970s. The age of the home is a clue, not proof.
A qualified electrical professional can help establish what wiring is present, how it has been connected and whether defects or unsuitable devices need attention. Don't remove outlets, switches or panel covers to inspect wiring yourself.
Is aluminum wiring unsafe?
Not automatically. Ontario's Electrical Safety Authority explains that aluminum wiring can be safe when proper connections and terminations are made without damaging the conductors and only appropriately approved devices are used.
The concern in an older installation is often the condition and compatibility of connections, rather than the mere presence of aluminum conductors. A professional should assess warning signs such as overheating, loose or deteriorated connections, damaged devices or previous alterations that may not have been completed correctly.
If you notice a burning smell, smoke, sparking or unusual heat, stop using the affected area and seek urgent assistance. See our emergency electrical repair service.
Repair, connection upgrades or full wiring replacement?
There is no one-size-fits-all answer. The correct scope depends on the existing installation, the number and condition of affected circuits, the devices in use, renovation plans and any insurer requirements.
Assessment and targeted repairs
An assessment may identify specific terminations, devices or circuits that need approved corrective work. A qualified contractor should determine what repair methods and components are appropriate under the applicable code and manufacturer instructions.
Partial rewiring during renovations
If walls are already open for a kitchen, basement or other renovation, there may be an opportunity to address part of the wiring in a coordinated way. That doesn't mean every home must be completely rewired.
More extensive aluminum-to-copper replacement
In some homes, replacement of affected wiring is the appropriate option because of its condition, the work being planned or insurer requirements. We'll discuss the trade-offs and scope rather than assume this is necessary in every case.
Aluminum wiring and home insurance in Ontario
Some insurers ask for an electrical inspection or evidence that identified deficiencies have been corrected before issuing or renewing coverage. Some may require replacement instead of repairs.
Contact your insurer first and ask for its exact requirements in writing. That helps avoid paying for work that doesn't satisfy the document it wants. The Electrical Safety Authority says an ESA Certificate of Acceptance may be relevant after corrective work; ask the contractor which documentation will apply.
We can discuss the work required once you know the insurer's position. The electrical contractor cannot guarantee an insurer will approve a policy.
What happens during a wiring assessment?
- Tell us why you're enquiring. Is this for safety, a renovation, a home purchase or an insurance condition?
- Review the installation. The relevant wiring, connections and equipment are assessed by a qualified professional.
- Discuss any deficiencies. We explain what needs attention and which options may be suitable.
- Agree on the scope. That might mean targeted corrective work, partial rewiring or broader replacement.
- Arrange required electrical notifications and documentation. Where work is carried out, applicable ESA processes should be followed.
If your project also involves a full renovation or panel upgrade, ask about coordinating the work.
What determines the cost of aluminum wiring replacement?
The biggest factors are the amount of wiring that needs attention, access to walls and ceilings, the existing circuit layout, panel condition, and whether targeted repairs or extensive rewiring are required. Occupied homes with finished walls can be very different from houses already opened up for renovation.
We'll work from the actual scope rather than give you an attractive but meaningless per-room estimate.
Frequently asked questions
Must all aluminum wiring be replaced in Ontario?
No. Aluminum wiring is not automatically prohibited or unsafe. The condition, connection methods, equipment and any specific insurance requirements determine the work needed.
Can I sell a home that has aluminum wiring?
A property's wiring may affect buyer questions, inspections or insurance, but aluminum wiring alone doesn't dictate the outcome. Get advice specific to the installation and transaction.
Will my insurance company accept a repair instead of a full rewire?
It depends on your insurer. Ask it for the required inspection, repairs, replacement or certificate details before commissioning the work.
Can I tell whether wiring is safe by looking at an outlet?
No. Electrical faults can be hidden and removing covers is hazardous. Arrange an assessment rather than investigating live wiring yourself.
Is it worth combining rewiring with a renovation?
Often, yes. Planned access to walls and ceilings can make it practical to coordinate corrective electrical work with a broader renovation.
