Anonymised, illustrative composite. A failed supply line in one Ontario condo unit flooded a floor below — and the corporation's first response mixed up two different questions that insurance actually keeps separate.
At a glance
A supply line behind an 8th-floor toilet failed overnight, and water travelled down through the floor slab into the corridor below and into the ceiling of the 7th-floor unit directly underneath. By the time it was discovered the next morning, three spaces needed repair: the unit of origin, a stretch of common-element corridor, and the 7th-floor unit’s ceiling and upper wall.
The property manager’s first move was the right one operationally — shut off water to the affected riser, call a restoration vendor, get drying equipment in within hours. The confusion started at the insurance step, once the question became who pays for what.
The corporation initially treated the entire repair as a single claim against its own master policy, on the assumption that anything damaged inside the building envelope was the corporation’s to insure. That is not how the coverage actually splits. As treadstonelaw’s explainer on condo insurance puts it, correctly: “The standard unit defines what is considered a ‘standard’ unit for insurance purposes… the finishes that were present when the building was originally built or when the standard unit by-law was passed” — the corporation’s policy covers common elements and that baseline, and nothing above it.
Both affected units had been renovated well above the standard-unit baseline — engineered hardwood in place of the original builder-grade flooring, and custom cabinetry in one unit’s vanity. Those upgrades were never the corporation’s to insure; they were always the individual owners’ responsibility under their own condo insurance, regardless of where the water came from.
Restoration estimates broke the $46,000 total repair cost into common-element work (corridor ceiling and drywall, roughly $9,000), standard-unit-level repairs in both affected units (subfloor, drywall, standard-grade flooring replacement, roughly $25,500), and the above-standard upgrades in both units (the engineered hardwood and custom cabinetry, roughly $11,500).
The first two categories, $34,500 combined, were properly the corporation’s claim. The remaining $11,500 was never the corporation’s loss to insure in the first place — it belonged to the two owners’ own policies from the start, independent of any chargeback question about who caused the leak.
The standard-unit boundary is a coverage-scope question, not a fault question, and the two get confused easily in the middle of an active flood. Whether the corporation can later recover its own deductible from the owner whose supply line failed is a separate issue entirely from whether the corporation’s policy ever covered the upgraded flooring in the first place. Getting the scope question right first is what let each owner submit the correct claim to the correct policy without delay.
That split traces directly to the Condominium Act, 1998: s.99(4) states that the corporation’s obligation to insure “does not include insurance for damage to improvements made to a unit,” and s.99(6) defines the standard unit itself as whichever governs first — a board by-law under s.56(1)(h), or, absent one, the schedule the declarant filed at registration under s.43(5)(h). A corporation that has never passed its own standard-unit by-law is still bound by that original schedule until it does.
The corporation’s policy paid the $34,500 common-element and standard-unit portion. Each affected owner filed a separate claim on their own condo insurance for the $11,500 in above-standard finishes, resolved within their own policy’s timeline rather than waiting on the corporation’s claim to close first.
The corporation’s water-response protocol was rewritten to include a standard-unit checklist at the estimating stage, before any claim is filed, so future incidents are split correctly from the start.
