Poly B and home insurance in Ontario

For most Ottawa homeowners, the insurer sets the deadline, not the pipe. Here is what companies are doing and what to ask before your renewal.

Why insurers care about a pipe that has not leaked

Water damage is one of the largest and fastest-growing categories of home insurance claim in Canada. Insurers price on national failure data rather than on your particular basement, and the data on Poly B — a material withdrawn from the Canadian plumbing code in 2005, with the oldest installations now approaching fifty years in service — reads badly. Industry estimates put roughly 700,000 Canadian homes as still containing it.

The four responses you may get

A premium surcharge

Coverage continues, you pay more. The most common outcome, and the easiest to miss on a renewal notice.

A replacement deadline

Renewal conditional on the pipe coming out within a stated period, with proof of the work.

A water-damage exclusion

The policy stays, but escape of water is carved out. This is the expensive one to overlook.

Declined or non-renewed

Less common, and more likely where there is a claim history or where the pipe is combined with other aged systems.

There is no single industry rule, and two insurers looking at the same Ottawa bungalow can land in different places. That is genuinely worth shopping.

Five questions for your broker

Does my current policy exclude or limit escape-of-water damage because of the supply piping?
Is there a surcharge on the policy today that is attributable to it?
If I replace it, what changes at renewal — and what proof do you need? An invoice, a permit, photos?
Does a partial replacement change anything, or do you need all of it gone?
If it fails and floods the basement, what exactly is covered?

Put it in writing. A phone call with an agent is not a coverage position. Ask for the answer by email, and keep it with the plumbing invoice — you will want both when you sell.

A common and costly misreading

Homeowners often assume that because insurance would cover a burst pipe, there is no reason to spend money in advance. Two problems with that. Coverage is for sudden and accidental damage, and an insurer who told you in writing to replace the pipe may take a different view of a later claim. And a claim is not free: there is the deductible, the claims history that follows you, the weeks of drying and rebuilding, and whatever the policy limits do not stretch to.

Replacement itself is not an insured expense. It is a maintenance decision that changes your risk profile, and occasionally your premium.
