Key takeaways
  • The corporation insures the building and the standard unit as its governing documents define it, and owners repair everything outside that definition.
  • Where an owner, tenant or resident causes the damage, the corporation can charge the lesser of the repair cost or its deductible.
  • Some by-laws shift the deductible to owners even when no one is at fault, so your own coverage and your building's documents matter.

Water escapes from a unit, a neighbour's ceiling stains, and suddenly the condo corporation mentions its insurance deductible and says it may be billed to you. It is a common and stressful moment, and the answer depends on what caused the damage and on your building's own documents.

This article explains in general terms how the corporation's insurance works, when an owner can be charged the deductible, and what your own insurance may need to cover. Your declaration and by-laws control the details, so treat this as a starting point.

What the corporation's insurance covers

An Ontario condo corporation must carry insurance and never let it lapse. Coverage must include damage to units and common elements, liability for failing to keep common areas safe or from using machinery, and directors' and officers' liability.

The corporation's property insurance does not cover improvements or non-standard elements of units. Fixtures, furnishings, equipment and personal property are generally not part of a standard unit, which each corporation defines in its governing documents.

The corporation repairs damage to the standard unit as defined in those documents. Owners must repair everything outside that definition, however the damage was caused.

When an owner can be charged the deductible

In plain words, a deductible is the portion of an insured loss that is paid before the insurance responds. In a condo, the question is who ends up bearing that portion.

If the damage is caused by an owner, tenant or resident, the corporation can charge the owner the lesser of the repair cost or the corporation's insurance deductible under s. 105(2). A chargeback is a cost the corporation bills to one owner, usually because of that owner's act or omission.

Some corporations have by-laws that make owners pay the deductible in more situations, including where no one is directly at fault. Deductibles can range from a few hundred dollars to tens of thousands.

If you cannot pay a chargeback added to your condo fees and no solution is reached, the corporation automatically has a lien against your unit for that debt.

Common situations at a glance

SituationHow the deductible may be treated
Your unit leaks because of something you, your tenant or a resident didThe corporation can charge you the lesser of the repair cost or its deductible
Your building has a deductible by-law and no one is at faultYou may still be charged, depending on the by-law
Damage is to your upgrades or belongingsNot part of the corporation's coverage, as they are generally outside the standard unit
Damage is within the standard unitThe corporation repairs it, as defined in its governing documents

Which of these applies to you depends on the wording of your building's declaration and by-laws, which a lawyer can review.

Your own insurance

No statute is cited as requiring owners to carry their own insurance. The Condominium Authority of Ontario says owners should strongly consider it, including property insurance for upgrades, fixtures, furnishings, equipment and personal property, and possibly legal expense insurance.

Your corporation's declaration, by-laws or rules may require owners to carry insurance, and then it is mandatory for that building. Tenants are not legally required to carry tenant insurance unless the tenancy agreement or the corporation's governing documents require it.

Owners exposed to deductible by-laws may need their own coverage for it, often called deductible or loss assessment coverage. Ask your insurance broker to confirm that your policy responds to a chargeback.

What to do after water damage

Frequently asked questions

Do I always have to pay the condo's deductible after a leak?

No. The Act lets the corporation charge the lesser of the repair cost or its deductible where an owner, tenant or resident caused the damage. Some by-laws go further and apply even where no one is at fault, so check your building's by-laws.

Does the condo's insurance cover my renovations and furniture?

Generally not. Improvements, fixtures, furnishings, equipment and personal property are usually outside the standard unit, which each corporation defines in its governing documents. Owners must repair everything outside that definition.

Can the corporation put a lien on my unit for an unpaid deductible charge?

If an owner cannot pay chargebacks added to their condo fees and no solution is reached, the corporation automatically has a lien against the unit for that debt. Speak with a lawyer early if you disagree with the charge.

Do tenants need insurance in a condo?

Tenants are not legally required to carry tenant insurance unless the tenancy agreement or the corporation's governing documents require it. It is still worth considering for their own belongings.
