Bed Bugs in an Ontario Condo: Who Is Responsible?

The Condominium Act, 1998 contains no reference to pests, insects, vermin or infestation. Neither does its general regulation, and neither does the Residential Tenancies Act, 2006. Every obligation described below is inferred from general language about maintenance, repair and habitability. Anyone who tells you what Ontario bed bug law requires of a condominium is describing something that does not exist as a standalone rule.

That matters because it explains why these disputes are slow. There is no section to point at. Responsibility is worked out from the maintenance provisions, the building's own declaration, and the facts of where the infestation is.

Section 90(1) sets the baseline. The corporation maintains the common elements and each owner maintains the owner's unit. Section 90(2) defines maintaining to include repairing after normal wear and tear, but not repairing after damage. Section 89 deals separately with repair after damage, which the corporation handles.

Pest treatment sits on the maintenance side of that line, not the damage side. So the starting point is straightforward. Treating the common elements, meaning hallways, shared walls, service chases and anything the declaration defines as common, is the corporation's cost and is shared by all owners as a common expense under section 84(1). Treating inside a unit is the owner's cost.

Section 91 lets the declaration move that line, but only in four specific ways, one of which is to make the corporation responsible for maintaining units. This is why two buildings on the same street can handle an identical infestation differently. Read your own declaration before assuming anything. Section 7(5) means that where a declaration conflicts with the Act, the Act wins.

Bed bugs do not respect the boundary between a unit and the common elements. They travel along baseboards, through wall voids and shared electrical and plumbing runs, and they arrive in one unit from another. The Act has nothing to say about this. It does not allocate responsibility according to where an infestation started, it does not require a corporation to treat neighbouring units, and it does not create anything resembling a polluter pays rule.

So the question of who pays when bed bugs spread from unit 804 into 904 and 704 is not settled by statute. It turns on the declaration and on the facts, and the facts are usually the harder part. Whether one unit was the source, and how far activity has actually reached, are evidentiary questions that a building rarely has an answer to. This is the point at which a canine sweep of a stack of units earns its cost, because it produces a dated map of where detectable activity is and is not.

Section 92(3) allows the corporation to carry out work an owner has failed to do, but the conditions are narrower than boards often assume. The owner must have failed to meet a maintenance obligation within a reasonable time, and that failure must present a potential risk of damage to the property or the assets of the corporation, or a potential risk of personal injury. It is permissive, not mandatory. A corporation that charges back without meeting that threshold is exposed.

Section 92(4) then deems the owner to have consented and adds the cost to the common expenses for that unit, which is what makes it lienable under section 85.

Section 92 itself contains no notice requirement. The expectation that an owner gets notice, a chance to obtain their own quotes and an opportunity to do the work themselves comes from the courts rather than the statute. In Beswick v. YRSCC No. 1175 the Superior Court held that without prior notice the expense was the corporation's to carry.

There is a related and expensive trap. In Amlani v. YCC 473 the Divisional Court invalidated a lien of just over $25,000, holding that legal and enforcement costs under section 134 cannot be added to common expenses and liened without a court order, even though actual work costs under section 92 can be. The treatment invoice and the lawyer's invoice are treated differently.

Section 19 lets the corporation, on giving reasonable notice, enter a unit at a reasonable time to perform its objects and duties. Two details get misreported constantly. The Act says reasonable notice, not twenty four hours, and it does not require the notice to be in writing. Declarations frequently impose more than the Act does.

The Act also contains no emergency entry provision. Emergency access rights, where they exist, come from the declaration. A board that assumes a statutory right to enter without notice is assuming something that is not there.

If an owner refuses access, the route is a compliance application to the Superior Court under section 134. In Carleton Condominium Corp. No. 25 v. Eagan the court ordered an owner to prepare a unit for treatment and, failing that, gave the corporation ongoing access to prepare and treat it, with costs of $9,703.80 added to the unit's common expenses.

A rented condo unit has three relationships running at once, and confusing them is the most common error in this area.

Between the tenant and the owner, the Residential Tenancies Act applies and the Landlord and Tenant Board decides. Section 20(1) makes the owner, as landlord, responsible for maintaining the unit in a good state of repair and fit for habitation. Section 3(4) means that where the two statutes conflict, the RTA prevails, so a declaration that puts in unit pest control on the owner does not reduce what the owner owes the tenant.

Between the owner and the corporation, the Condominium Act applies. Chargebacks under section 92 run against the owner, never against the tenant.

Between the corporation and the tenant, section 119(1) binds occupiers directly to the Act, the declaration, the by-laws and the rules, so the corporation can act against a tenant. But a condominium corporation is not a landlord as the RTA defines it, which means it cannot file at the Landlord and Tenant Board and a tenant cannot bring the corporation there either. Section 134(4) also prevents a court from terminating a residential lease on a first application. The corporation gets a compliance order first, and only a breach of that order opens the question of the lease.

This is the point most published guidance gets wrong. Infestation disputes do not go to the Condominium Authority Tribunal. The Condominium Authority of Ontario, which administers the Tribunal, states plainly that infestation is not something you can take there.

The reason is structural. The Tribunal only hears prescribed disputes. Pests are not on the prescribed nuisance list, which covers odour, smoke, vapour, light, vibration and unreasonable noise. And section 1.36(4)(a) bars the Tribunal from hearing disputes about section 117(1), which covers conditions likely to damage property or cause injury or illness. A bed bug infestation is close to a textbook section 117(1) condition, which is what pushes these cases out of the Tribunal.

The route is the Superior Court under section 134, usually after the mediation and arbitration process in section 132 where the dispute concerns the declaration, by-laws or rules. Filing at the Tribunal by mistake is not a neutral error, because the two year limitation in section 1.36(6) keeps running while it is dismissed. An owner who believes the corporation is unfairly disregarding their interests also has the oppression remedy in section 135.

Buyers often assume a status certificate would disclose a building's infestation history. It does not. Section 76(1) sets out a closed list of what must be disclosed, covering common expenses, budgets, the reserve fund, insurance, litigation, leases and agreements. Pest history is not on it, and section 76(4) treats an omission as a statement that no such information exists.

If a building's infestation history matters to a purchase, the certificate is not where you will find it, and a pre purchase inspection of the unit is the only direct answer available to a buyer.

A canine inspection establishes where detectable bed bug activity is on a given date. In a condo that is usually the missing fact. Whether the unit below is affected, whether activity has reached a hallway or a shared wall, whether a treated unit is now clear, and whether a complaint reflects a live infestation or an old one are all questions a sweep can answer and an argument between neighbours cannot.

What we do not do is decide who pays. That comes from the declaration, the Act and, when it goes that far, a court. We produce the dated record of findings that those decisions get made on.
