The hard part is rarely recognizing a broken furnace or active leak. It is deciding what the law requires when the problem is smaller, recurring, partly caused by use, or reported without enough detail, and then proving that the response was reasonable.
The legal baseline
The duty follows the condition, not the lease wording
Section 20 of Ontario's Residential Tenancies Act places the core repair obligation on the landlord. A lease clause cannot simply make a tenant responsible for every repair, and a tenant's agreement to accept an existing defect does not erase the statutory duty.
The standard is broader than emergency work. A condition can require attention because it is unsafe, makes the unit unfit, breaches a provincial or municipal standard, or means a supplied component is no longer in good repair. Ontario Regulation 517/06 adds concrete standards for matters such as structural elements, plumbing, heating, ventilation, electrical systems, doors, windows, walls, ceilings, floors, pests, appliances, and common areas where the regulation applies.
Safety and habitability
Heat, water, electrical and structural conditions, locks, sanitation, mould or pest conditions, and other issues that may affect safe occupation.
Landlord-supplied systems
Plumbing, drainage, heating, ventilation, fixtures, and appliances the landlord supplied must be kept safely operable and in good repair.
The whole residential complex
The duty is not limited to the unit. Common areas, exterior elements, stairs, elevators, parking and other shared facilities may also fall within the repair and standards framework.
Workmanship and standards
A patch is not enough if it leaves the condition unsafe or below an applicable provincial or municipal maintenance standard.
Responsibility
Landlord repair, tenant cleanliness, or tenant-caused damage?
Start with the source of the condition. Ordinary wear, age, failure of a landlord-supplied fixture, building-envelope issues, and systems that no longer work safely ordinarily point back to the landlord's repair duty. A tenant, meanwhile, must maintain ordinary cleanliness under section 33 and repair undue damage caused wilfully or negligently under section 34.
| Situation | Starting point | What to document |
|---|---|---|
| Aging faucet begins leaking | Landlord repair | Age, leak location, report time, shut-off advice, invoice and completion photos |
| Wall paint scuffs from ordinary use | Likely wear, not automatic tenant damage | Move-in record, length of tenancy, extent and cause |
| Door broken by an occupant | Repair promptly; investigate tenant liability separately | Incident facts, photos, witness/vendor notes and actual repair cost |
| Mould reported around a window | Investigate cause; do not assume lifestyle | Moisture readings, ventilation, leaks, exterior condition, communications and remediation |
Even where tenant-caused damage may justify recovery of a reasonable repair cost or another lawful step, delaying a safety-critical repair while arguing about fault can increase damage and risk. Separate the immediate work from the later liability decision.
Response time
“Reasonable” starts with triage, not one universal countdown
The RTA does not give every maintenance report the same fixed response deadline. Urgency depends on the condition, applicable standards, foreseeable harm, weather, availability of parts or trades, and the steps taken while a permanent repair is arranged.
Emergency
Fire, major flooding, gas concern, loss of a vital service, exposed electrical risk, security failure, or another immediate threat. Act now and contact emergency or utility services where appropriate.
Urgent
A condition likely to cause significant damage, loss of essential use, health risk, or rapid deterioration. Acknowledge quickly, stabilize, and set a near-term plan.
Routine
Non-safety defects and ordinary repairs. Confirm receipt, give a realistic window, schedule access, and update the tenant if the date changes.
A prompt acknowledgement does not substitute for repair, but silence is avoidable evidence against the landlord. If the final fix is delayed, record the reason, interim protection, vendor schedule, tenant update, and next checkpoint.
Entry
Use the emergency rule narrowly and document ordinary access properly
Section 26 permits entry without notice in an emergency or when the tenant consents at the time of entry. For ordinary inspection, repair, or replacement work, section 27 generally requires at least 24 hours' written notice stating the reason, date, and a time between 8 a.m. and 8 p.m.
Do not label routine work an emergency merely to avoid notice. Keep the notice or consent, delivery method, scheduled window, attending contractor, entry time, work performed, and any rescheduling communication with the maintenance record.
Evidence workflow
Build the repair file while the work is happening
- 1
Capture the report
Preserve the tenant's words, submission channel, date, time, property, unit, photos, and any immediate safety detail.
- 2
Acknowledge and triage
Confirm receipt, assign priority, give immediate safety instructions where appropriate, and state when the next update will arrive.
- 3
Record access
Keep written notice, tenant consent, proposed windows, failed-access facts, and contractor attendance.
- 4
Connect the work
Attach estimates, work orders, invoices, parts, vendor notes, before-and-after photos, and any related expense.
- 5
Verify and close
Confirm what was completed, test the affected function, ask the tenant to report recurrence, and record the completion communication.
DwellTrack's maintenance workflow keeps this sequence attached to the property, while guided inspection records preserve the condition before, during, and after a tenancy.
If the record breaks down
What a tenant may do when repairs are not completed
The LTB's maintenance guidance says a tenant can contact the landlord, seek municipal inspection or enforcement where available, and file a T6 application alleging maintenance failures. Potential remedies can include an order to complete work, a rent abatement, reimbursement of certain costs, or other relief the LTB is authorized to grant.
A tenant should not simply stop paying rent because of a maintenance problem without a lawful basis or order. For both sides, the strongest file is chronological: what was reported, what condition existed, what each person did, what access was available, what work occurred, and whether the problem remained.
