Is Mold Damage Covered by a Standard Home Insurance Policy?
It depends on what caused the mold. As a general rule, Ontario insurers distinguish between mold that resulted from a sudden, accidental, covered event and mold that developed gradually, which is typically excluded. This table is a general guide only — always confirm the specifics with your own insurance provider or broker.
| Type of Mold Damage | Usually Covered by a Standard Policy? | How to Make Sure You're Protected |
|---|---|---|
| Mold from a sudden event, such as a burst pipe or appliance failure | Often yes, since the underlying water damage is typically covered. | Report and remediate quickly — most policies require prompt notice and mitigation to keep coverage intact. |
| Mold from a sewer back-up | Only with a sewer back-up endorsement added to your policy. | Confirm you carry a sewer back-up endorsement, since it's rarely included by default. |
| Mold from overland flooding, such as heavy rain or surface water | Only with overland water coverage added to your policy. | Confirm you carry overland water coverage, particularly if your property is in a flood-prone area. |
| Mold from gradual leaks or long-term moisture | Usually no — treated as a maintenance issue. | Address minor leaks and humidity promptly; routine inspections can catch problems before they become exclusions. |
| Pre-existing mold not disclosed at time of purchase | No — pre-existing conditions are excluded. | Have a professional mold inspection done before purchasing a property. |
