- Every condominium’s declaration defines exactly where the "unit" ends and the "common elements" begin.
A pipe fails behind your bathroom wall. A window won’t seal properly. Your balcony door frame is rotting. In every case, the same question comes up first: is this mine to fix, or the condo corporation’s?
Who pays for condo repairs in Ontario depends less on common sense and more on two specific documents — the Condominium Act’s default rules, and your building’s own declaration, which can, and often does, shift responsibility away from that default. Getting this wrong can mean paying for a repair you were never responsible for, or missing a claim the corporation should have covered.
The Default Starting Point
Ontario’s Condominium Act, 1998 sets out a general default allocation of repair responsibility: the corporation is generally responsible for repairing the common elements after damage, and an owner is generally responsible for repairing their own unit after damage — unless the corporation’s declaration says otherwise. Because that "unless" is doing a lot of work, the declaration — not general assumptions — is where the real answer to a specific repair question lives.
Why the Declaration Matters More Than Instinct
Every condominium’s declaration defines exactly where the "unit" ends and the "common elements" begin. This boundary isn’t always where you’d expect. A window, for example, might be physically attached to your unit but defined by the declaration as a common element that the corporation is responsible for maintaining — or the reverse. The same goes for balconies, in-suite plumbing that services multiple units, and mechanical components shared across the building.
This is why two condo owners with what looks like the identical problem — a leaking window, say — can get different answers about who pays, simply because they live in different buildings with different declarations.
Typical Repair Categories: A General Guide
| Item | Often the Corporation’s Responsibility | Often the Owner’s Responsibility |
|---|---|---|
| Common hallways, lobbies, elevators | Yes | — |
| Building exterior, roof, structural elements | Yes | — |
| Windows and balcony doors | Frequently, but declaration-dependent | Sometimes |
| Balcony structure itself | Frequently, but declaration-dependent | Sometimes, for surface finishes |
| In-suite plumbing serving only your unit | — | Often |
| Shared plumbing or mechanical stacks serving multiple units | Often | — |
| Interior finishes (flooring, paint, cabinetry) | — | Yes |
| Appliances inside the unit | — | Yes |
| HVAC equipment exclusively serving your unit | Declaration-dependent | Declaration-dependent |
This table describes general patterns, not a rule you can rely on for your specific building — the only way to know for certain is to check your declaration, and, where damage has already occurred, to review the situation with a lawyer.
When Damage Crosses the Line
Some of the most contentious repair disputes happen when damage starts in one place and spreads — a pipe failure inside your unit that damages the unit below, for example. These situations often involve both repair-responsibility questions and insurance questions at the same time, since the corporation’s master policy and individual owners’ policies can each respond to different parts of the loss. This is a common source of dispute precisely because two questions — "whose responsibility was it to maintain this?" and "whose insurance pays for the damage?" — don’t always have the same answer.
Steps to Take When a Repair Dispute Comes Up
- Check your declaration’s definition of "unit" and "common elements" for the specific item in question.
- Review your status certificate or recent corporation communications for any related rules or policies.
- Notify the property manager or board promptly — delays can complicate both the repair and any insurance claim.
- Document the damage and any communications in writing.
- If responsibility is disputed or the amounts are significant, get a lawyer’s opinion before you pay for, or dispute, a repair.
Frequently asked questions
My declaration says windows are a common element, but the corporation says it’s my responsibility. What now?
This is worth raising formally and, if it isn’t resolved through the property manager or board, getting a lawyer to review the specific declaration language — general assumptions about "how it usually works" don’t override what your building’s declaration actually says.
Does the corporation’s insurance cover damage inside my unit?
The corporation’s master policy is generally structured around the building and common elements; damage to your personal belongings and, depending on the declaration, certain interior improvements, is typically your own policy’s responsibility. This is exactly why owners are usually advised to carry their own condo insurance in addition to the corporation’s master policy.
Can the corporation make me pay for a common element repair through a special assessment?
Yes — if a common element repair isn’t fully covered by the reserve fund or existing budget, the corporation can generally levy the cost across owners, sometimes through a special assessment, according to each unit’s proportionate share.
What if I disagree with the corporation about whose responsibility a repair is?
Start with a written request for the corporation’s position and the declaration language it’s relying on. If you can’t resolve it directly, a real estate lawyer can review your declaration and advise on your options.
