Key takeaways
  • Condo corporations must keep insurance in force against damage to units and common elements, liability, and directors and officers' risks.
  • The corporation's property insurance does not cover improvements or non-standard elements of units, which the owner insures and repairs.
  • Your building's standard unit definition decides what is covered and what is an improvement.
  • Deductibles are a common gap: owners can be charged for them in some situations.

Many owners assume the corporation's insurance means their unit is fully protected, and then discover after a leak or fire that part of the loss is theirs.

This article explains what the corporation must insure, how the standard unit definition draws the line, and where gaps tend to land on owners.

What the corporation must insure

Condo corporations must maintain insurance and keep their policies from lapsing. The required cover includes:

Corporations must be insured against major perils including fire and water leaks. Property insurance is often called the master policy, though the labels in your building's documents may vary.

The standard unit: where coverage stops

The corporation's property insurance does not cover improvements or non-standard elements of units. Anything outside the standard unit definition is an improvement, and the owner is responsible for insuring and repairing it.

The governing documents define the standard unit, and standard unit definitions generally exclude alterations or renovations. A corporation with no standard unit by-law must use the declarant's standard unit definition schedule.

ItemGenerally treated as
Walls, doors and plumbingPart of the standard unit
Appliances and flooringOwner improvements
Fixtures, furnishings and personal propertyNot part of a standard unit
Renovations and upgradesOutside the standard unit

These are general guides. The answer for your unit depends on how your building defines the standard unit, so check that document.

Repairs and who does them

Corporations are generally responsible for repairing damage to common elements and standard unit elements. Section 90 sets how maintenance obligations are divided, and governing documents can alter them.

This is why your declaration matters. Two buildings can divide repair duties differently, and the same damage may be the corporation's job in one building and partly yours in another.

Where the gaps land on owners

Deductibles can range from a few hundred dollars to tens of thousands. When an owner and the corporation both claim for the same damage, each usually pays its own deductible.

The CAO advises owners to take out their own property insurance, including cover for unit upgrades, personal belongings and non-standard parts of the unit. Liability for a leak from one unit into another depends on the declaration, the Act and general law, so a serious dispute is worth taking to a lawyer.

Deductibles and chargebacks in more detail

A deductible is the part of a loss that insurance does not pay. In a condo, who bears it can matter as much as who is insured, so it helps to see the usual patterns side by side.

SituationWhat generally happens
You make a claim on your own policyYou are generally responsible for your own deductible
You or your guests damage common elements through direct action or negligenceYou can be responsible for the deductible
An owner, tenant or resident causes damageThe corporation must charge back the lesser of the repair cost and its deductible
You and the corporation both claim for the same damageEach usually pays its own deductible
No one is at faultBy-laws can extend owner responsibility for the corporation's deductible, including where no one is at fault

If you disagree with a chargeback, where the dispute goes depends on the underlying issue. The Condominium Authority Tribunal handles chargebacks only where the underlying issue is within its jurisdiction, such as nuisance, parking, pets or condo records. Most repair and damage chargebacks go to mediation, arbitration or the Superior Court of Justice.

Compliance costs such as legal letters cannot be charged back without Tribunal or court permission.

Insurance is not the only way a loss can reach your wallet. A budget shortfall, such as an unforeseen repair, can force the corporation to levy a one-time special assessment. Special assessments are shared by owners in the same percentages used for common expenses, and owners must pay their portion.

What to do next

If you are unsure whether a loss is the corporation's responsibility or yours, get advice before you pay or sign anything.

Frequently asked questions

Does the corporation insure the inside of my unit?

It insures against damage to units and common elements, but not improvements or non-standard elements. What counts as standard depends on your building's definition.

Is my flooring covered by the corporation's policy?

Flooring is generally treated as an owner improvement, so it is usually for you to insure and repair. Check your standard unit definition to be sure.

Who pays when a pipe bursts?

Corporations are generally responsible for repairing common elements and standard unit elements, subject to the governing documents. If someone caused the damage, charge-back rules may apply. Fault between units is decided under the declaration, the Act and general law.

Do I still need my own insurance?

The CAO advises owners to take out their own property insurance. Your declaration or by-laws may require it, so check them.

Can the corporation charge me for its deductible?

If an owner, tenant or resident causes damage, the corporation must charge back the lesser of the repair cost and its insurance deductible. By-laws can also extend owner responsibility for the corporation's deductible, including where no one is at fault.
