Does “Guaranteed Rebuilding Cost” Cover Every Rebuilding Expense?

When homeowners purchase “Guaranteed Rebuilding Cost” coverage, they may reasonably believe their insurer will pay whatever it costs to rebuild their home after a total loss. However, the Supreme Court of Canada’s decision in Emond v. Trillium Mutual Insurance Co., 2026 SCC 3 confirms that the word “guaranteed” must be understood in the context of the entire insurance policy.

In practical terms, guaranteed replacement cost insurance may increase the amount an insurer will pay, but it does not necessarily expand the types of expenses that are covered.

What Did the Supreme Court of Canada Decide in Emond v. Trillium?

Stephen and Claudette Emond’s home was severely damaged by flooding and declared a total loss. Their homeowners’ insurance policy included a Guaranteed Rebuilding Cost insurance, which allowed them to recover the cost of rebuilding even if that cost exceeded the basic policy limit.

Rebuilding the home required additional work to comply with conservation authority requirements and other regulations. Those requirements significantly increased the overall reconstruction cost.

The homeowners argued that their Guaranteed Rebuilding Cost endorsement required Trillium Mutual Insurance Company to pay the entire cost of rebuilding, including the additional regulatory compliance expenses.

Trillium accepted that the endorsement applied but relied on another part of the policy that excluded increased rebuilding costs resulting from laws, regulations and by-laws.

The Supreme Court agreed with the insurer. It found that the Guaranteed Rebuilding Cost endorsement increased the amount available to rebuild the home, but it did not override the policy’s exclusion for regulatory compliance costs.

How Do Courts Interpret Insurance Policies?

The Court reaffirmed the approach established in Ledcor Construction Ltd. v. Northbridge Indemnity Insurance Co., 2016 SCC 37: an insurance policy must be read as a whole.

Clear policy language will generally be given its ordinary meaning, as it would be understood by the average person applying for insurance. An endorsement is not a separate contract that can be read in isolation. It changes certain parts of the underlying policy but remains connected to the policy’s other terms, conditions and exclusions.

Only where the wording is genuinely capable of more than one reasonable interpretation will courts turn to additional principles, such as the reasonable expectations of the parties or resolving an ambiguity against the insurer.

The Court also rejected the argument that the exclusion effectively defeated the purpose of the coverage. The endorsement still provided meaningful protection because it removed the basic dollar limit on otherwise covered rebuilding costs. It simply did not cover every category of expense.

What Does the Edmond Decision Mean for Homeowners?

The name of an insurance product does not tell the whole story. Even where a policy promises “guaranteed” rebuilding costs, exclusions elsewhere in the policy may limit what the insurer must pay.

Following a fire, flood or other major loss, rebuilding may require homeowners to:

  • comply with updated building codes;
  • meet municipal or conservation authority requirements;
  • relocate or elevate part of the structure;
  • install new safety features; or
  • complete other legally required upgrades.

These expenses can add substantially to the cost of rebuilding. Whether they are covered will depend on the wording of the policy, including any endorsements and exclusions.

Homeowners purchasing or renewing insurance may wish to ask specifically whether their policy covers increased costs caused by upgrades to building codes, zoning requirements, conservation rules or other laws. “Guaranteed Rebuilding Cost” coverage should not automatically be treated as a guarantee that every rebuilding expense will be paid.

What Determines Whether an Insurer Must Pay Rebuilding Costs

Although the insurer succeeded in Emond, the decision does not give insurers a blanket right to deny regulatory or code-upgrade expenses. Every claim depends on the particular wording of the policy and the circumstances of the loss.

Coverage may turn on:

  • the language of the rebuilding endorsement;
  • the wording and location of the exclusion;
  • whether the endorsement modifies another policy provision;
  • the cause and nature of the additional expense; and
  • whether the insurer’s interpretation leaves meaningful coverage in place.

Insurance policies are complex, and seemingly similar policies can provide very different protection. Before accepting a significant limitation or denial, homeowners should understand how the insurer has interpreted the policy as a whole.
