Condo water damage in Ontario: who repairs what

General guidance for Ontario. Requirements are interpreted by your municipality, so confirm the specifics for your property before you commit to a plan.

The first hour: stop the water, then call management

Shut off the water at the fixture or the unit's shut-off valve if you can find it, and call the property manager or the front desk right away. If the water is coming from above, from a wall or from the ceiling, it may not be your plumbing at all, and only management can get into the other unit or the riser.

Before anything is torn out, take photos and video of every wet ceiling, wall, floor and cabinet, and note the time you found it. Then call your own insurer. Where the water started is the single most important fact in everything that follows, so write down what you saw and who you spoke to.

Who repairs what: the standard unit and improvements

In an Ontario condo, the corporation's insurance covers damage to the common elements and to the 'standard unit'. Your condo's governing documents define what the standard unit is, and it generally includes things like walls, doors and plumbing. Anything beyond that definition counts as an improvement, such as upgraded flooring, custom cabinetry or appliances, and the owner is responsible for insuring and repairing it.

So one leak often means two scopes of work. The corporation's side brings the unit back to its standard definition, and the owner's side restores whatever was upgraded. Ask management for the standard unit definition early. It decides who pays for each line of the rebuild.

Who repairs and who pays are not always the same thing. Responsibility also depends on the exact wording of your declaration and by-laws, and on where the water came from: a dishwasher hose inside a unit is treated differently from a common-element pipe.

When the condo can charge you the deductible

Usually the corporation and each owner pay their own deductibles. The Condominium Act, 1998 makes an exception: if an owner, or someone they are responsible for such as a tenant, causes damage to their unit through an act or omission, the lesser of the repair cost and the corporation's deductible can be added to that owner's common expenses. Corporations can also pass a by-law that widens when owners are charged back.

Ontario courts have treated 'act or omission' as a question of cause, not fault. In Lozano v. TSCC No. 1765, the court accepted that leaving the water on during a months-long absence contributed to a flood, even though the owners were not careless in the ordinary sense. Condo deductibles for water damage can be high, and CTV News Toronto has reported on an owner surprised by a large chargeback bill.

Practical takeaway: ask management for the corporation's deductible and any chargeback by-law, and check with your broker that your own policy covers it. This is general information, not legal advice. Speak to a condo lawyer about a specific dispute.

Drying is not the rebuild

A restoration company stops further damage. It extracts water, removes wet drywall, baseboard and flooring, and dries the unit. Its job usually ends with open walls and a bare floor. Most online advice stops there too, and that is where owners and managers get stuck.

The rebuild is a separate job: new insulation and drywall, taping and paint, ceilings, flooring, trim, doors, cabinets and fixtures put back so the unit can be lived in or rented again. The common holdups are finishes that no longer match the rest of the suite, two insurers each approving only their part of the scope, and trades that cannot start until the moisture readings are signed off.

Settle these before the walls go back up

Getting these answered first avoids most rebuild delays and arguments.

• Which items are standard unit (corporation's scope) and which are improvements (owner's scope), in writing.
• Whose adjuster approves which part, and who your contractor reports to.
• Moisture readings or a drying sign-off before anything is closed in.
• Matching flooring, cabinet doors and paint: replace the damaged area only, or the whole continuous run.
• Building rules for contractors: elevator booking, work hours, certificates of insurance and parking.
• Whether the unit below or beside you was affected, so all the rebuilds can be scheduled together.

For property managers, boards and landlords

For a manager, a leak usually means several units, an anxious owner in each, and adjusters who want documentation. One contractor who can work to each insurer's scope, keep a photo record at every stage and coordinate access through the building saves the most time. For a landlord, a leak in a tenanted suite is often a good moment to do the turnover work at the same time, while the unit is already open.
