Ontario · Condominium Act, 1998
Most boards remember that an owner who causes damage pays the deductible. Far fewer remember the words that follow, which confine that rule to damage to the owner’s own unit. Damage to the common elements or to a neighbour is a common expense unless a by-law says otherwise.

Section 105(1) of the Condominium Act, 1998 sets the default: the part of a loss that falls inside a deductible is a common expense. Everyone pays. Section 105(2) is the exception, and it is narrower than its reputation:
“… if an owner, a lessee of an owner or a person residing in the owner’s unit with the permission or knowledge of the owner through an act or omission causes damage to the owner’s unit, the amount that is the lesser of the cost of repairing the damage and the deductible limit of the insurance policy obtained by the corporation shall be added to the common expenses payable for the owner’s unit.”
Read the four words in italics. The automatic chargeback reaches damage to that owner’s own unit. A burst hose that soaks the corridor, or the unit downstairs, is not caught by s. 105(2) at all. That damage stays a common expense under s. 105(1) unless the corporation has passed a by-law under s. 105(3).
This is the point boards most often have backwards, and it is expensive in both directions. Charge an owner for corridor damage with no by-law in place and the corporation is levying something the Act does not authorise. Assume nothing can be charged and the corporation absorbs a cost a by-law could have placed where it belongs.
Section 105(3) lets a by-law extend the circumstances in s. 105(2), which is how corridor and neighbouring-unit damage becomes chargeable. It has one hard limit, and the limit is not negotiable by by-law:
“… but not where the damage was caused by an act or omission of the corporation or its directors, officers, agents or employees.”
So a by-law can reach a tenant, a guest and a neighbour’s unit. It can never reach back to the corporation itself. If the contractor the corporation hired flooded the building, no by-law makes that an owner’s charge.
Where the chargeback applies, the amount is the lesser of the cost of repairing the damage and the deductible limit. A $2,000 repair against a $25,000 deductible is a $2,000 charge, not $25,000. Boards that bill the full deductible regardless of the repair cost are overcharging, and the arithmetic is right there in the subsection.
Section 105(4) then makes that amount an insurable interest of the owner, which is the statutory basis for the deductible coverage that sits inside most condominium unit-owner policies. It is worth telling owners this exists.
