Aluminum wiring does affect home insurance in Manitoba. Many insurers treat it as high-risk, much the way they treat knob and tube, and some will not write or renew a policy until the wiring has been assessed and repaired. The useful news with aluminum is that a documented remediation, usually pigtailing, is often enough to make a home insurable again without a full rewire.
If your renewal has come back with a question about aluminum wiring, or a sale is hung up on it, this guide explains what Manitoba insurers actually do, why, and the fix that gets you back to a normal policy.

Insurers price aluminum wiring as a higher risk, and how each one handles it varies. The trade publication Canadian Underwriter notes that most insurers view homes with knob and tube, aluminum wiring, and 60-amp service as high-risk, which is enough to complicate coverage on its own. The table covers the responses we see most often when a Manitoba homeowner has aluminum wiring.
| How the insurer responds | What it means for you |
|---|---|
| Requires an inspection first | A licensed electrician’s assessment of the wiring is needed before a coverage decision. |
| Covers it at a higher premium | Some insurers will write the policy with a surcharge for the added risk. |
| Requires remediation before coverage | The connections must be repaired, usually by pigtailing, and documented before a policy is issued. |
| Declines the home | A few insurers will not cover active aluminum wiring at all, so you shop elsewhere or remediate. |
Which response you meet depends on the insurer and on whether the wiring has already been remediated. What stays consistent is that ignoring it is rarely an option once an insurer knows the wiring is there, because your mortgage lender relies on that policy too.
Insurers treat aluminum as a risk because its connections can loosen and overheat over the decades, and overheating connections are a known cause of house fires. The U.S. Consumer Product Safety Commission has reported that homes with pre-1972 aluminum wiring are far more likely to have connections reach fire-hazard conditions than copper-wired homes, a figure often cited at 55 times. We explain the mechanism, which sits at the connections, in our aluminum wiring risks guide.
From the insurer’s point of view the reasoning is straightforward. Anything that raises the odds of an electrical fire raises the odds of a claim, so they want to see the wiring either repaired or priced for the risk before they take it on.
A documented, inspected remediation is what turns an aluminum-wired home back into a normal risk for an insurer, and for most homes that means pigtailing rather than a full rewire. The Electrical Safety Authority describes the path plainly: have a licensed electrician assess and repair the wiring, then provide the insurer with the inspection documentation as a record that the work was done. That paperwork is the part that satisfies the insurer.
In Winnipeg, the way you get that record is to have the remediation done under a permit and inspection, so the finished work is signed off to the Manitoba Electrical Code. This is the key difference from knob and tube, where insurers often want the old wiring fully removed. With aluminum, repairing the connections to a documented standard is usually enough, which makes it a far smaller job than a rewire for most homes.
Yes. If you know your home has aluminum wiring, you are expected to disclose it when you apply for coverage and at renewal. It is a material fact, and leaving it off an application can give an insurer grounds to reduce or deny a claim later, which is the opposite of what you are paying for. Disclosing it up front, and dealing with any remediation an insurer asks for, keeps you and the policy on solid ground.
Aluminum wiring tends to surface during a sale, and it can slow one down. When a buyer’s home inspection flags it, the buyer often runs into the same insurance questions you would, and a lender will not finance a home the buyer cannot insure. Handing over documentation that the wiring has been remediated and inspected clears that hurdle for the buyer and their insurer at once. A couple of situations we see in Winnipeg:
If a home turns out to need more than a connection repair, our cost to rewire a house in Winnipeg guide covers what a full rewire runs, and an electrical inspection gives you the written assessment insurers ask for.
Yes. Many Manitoba insurers treat aluminum wiring as high-risk and may require an inspection, charge a higher premium, or ask for the connections to be remediated before they will provide coverage. A few decline it outright. Disclosing the wiring and, where needed, having it remediated and documented is what keeps a home insurable.
Some will, but many will not. A number of insurers cover aluminum-wired homes, sometimes after an inspection or at a higher premium, while a few decline active aluminum wiring entirely. Having the connections remediated and inspected widens the pool of insurers willing to write the policy and usually improves the terms.
For most insurers, yes, when it is done properly and documented. Pigtailing repairs the aluminum connections with copper leads and approved connectors, which addresses the actual risk, and an inspection record proves the work was completed to code. Some insurers have specific requirements, so it is worth confirming what yours will accept before the work starts.
Yes, you can sell a home with aluminum wiring, though it can complicate the sale. Buyers face the same insurance questions, and lenders will not finance a home the buyer cannot insure, so deals can stall on the inspection. Remediating the wiring beforehand, or providing documentation of a completed remediation, keeps the sale moving.
Often, yes. Insurers commonly want proof that aluminum wiring has been assessed and, where needed, repaired, and an inspection record is that proof. In Winnipeg that means having the work done under a City permit and inspected, so you receive the documentation to give your insurer.
