Who is responsible for heating and hot water?

In Ontario, landlords are generally required to provide and maintain vital services like heat and hot water so the unit meets basic habitability standards under the Residential Tenancies Act, 2006.[1] Tenants must allow reasonable access for repairs and should report problems promptly in writing so there is a clear record.

Landlords must maintain heat and hot water so rental units meet basic living standards.

Urgent repairs and timelines

Loss of heating or hot water is usually treated as an urgent repair. If a system fails in cold weather or creates unsafe conditions, landlords should arrange repairs as quickly as possible. If the landlord does not act, tenants can seek help from municipal building or public health officials and from the Landlord and Tenant Board for enforcement or orders.[3][2]

Document the date, time, and who you contacted when reporting an urgent repair.

Practical steps to take right away

  1. Notify the landlord or property manager in writing with the problem, the time it started, and a request to repair.
  2. Keep records: photos, videos, and copies of messages or written requests.
  3. If the landlord arranges a repair, keep the technician’s name, date, and a receipt if work was billed to you.
  4. If unresolved, consider filing an application with the Landlord and Tenant Board for an order to repair and any rent abatement you request.
Good documentation improves your options if you need a formal order.

When tenants can arrange repairs themselves

Tenants sometimes pay for emergency repairs to prevent loss or danger; keep all receipts and written proof. You may be able to ask the Landlord and Tenant Board to order repayment or a rent reduction if the repair was the landlord’s responsibility and you had to act to prevent harm.

Always get written approval if you plan to hire a technician and expect reimbursement.

How to file with the Landlord and Tenant Board

Use the Landlord and Tenant Board's application forms and guides to start a claim when a landlord will not fix heating or hot water. The Board website lists available application types and instructions; the exact form name and number are available on the official forms page. Typical tenant applications ask for an order to repair, a rent abatement, or both.[2]

The Board considers evidence like photos, written requests, and technician receipts when making orders.

Routine repairs vs emergency repairs

Routine maintenance (filters, minor leaks) should be scheduled and allowed reasonable time to be fixed. Emergencies (no heat in winter, no hot water, gas leaks) require quicker action and may justify faster escalation to authorities or the Board. For practical guidance on emergencies and tenants’ rights, see Emergency Situations and Repairs: Tenant Rights and Responsibilities and for everyday responsibilities see Routine Repairs in Rental Units: Tenant and Landlord Responsibilities.
