Landlord Maintenance Obligations: What Ontario Property Owners Must Know

Maintaining a rental property isn’t optional — it’s a legal and practical responsibility that protects tenants, preserves asset value, and reduces costly emergency repairs. For landlords operating in Ontario, the baseline duties are established by provincial rules and local bylaws: keep everything you supply in working order, provide agreed-upon “vital services,” comply with fire and safety codes, and respect tenant privacy and notice requirements. These obligations are not only about avoiding disputes — they are about running safer, more reliable properties that attract and keep good tenants.

Core responsibility: keep what you provide in good repair

If you supply an item or system — from a heating system and plumbing to appliances and locks — you must maintain it. The Residential Tenancies Act and related provincial regulations make the landlord responsible for repair and replacement when items fail through normal wear and tear or accidental damage. In practice, that means timely response to repair requests, preventive maintenance (where appropriate), and budgeting for replacement of aging infrastructure before failures cascade. Documenting repairs and the condition of unit components at move-in and move-out reduces disagreement later.

Vital services and heating: what “always supplied” means

Certain services are legally considered “vital” — typically hot and cold water, electricity, gas, and, during the heating season, heat. If you agree to supply a vital service, you cannot withhold it as a response to tenant issues such as arrears or disputes. Provincial regulation sets minimum heating standards: commonly interpreted as maintaining a minimum of about 20°C from the start to the end of the heating season (municipal standards sometimes differ), so check local bylaws for stricter rules. Treating heat and utilities as essential preserves habitability and avoids regulatory penalties.

Fire safety and alarms: installation, testing, records

Fire and life-safety measures are non-negotiable. Landlords are responsible for installing and maintaining smoke and carbon monoxide alarms, ensuring clear fire exits, and keeping electrical and ventilation systems up to code. The Ontario Fire Code requires landlords to test alarms at prescribed intervals and keep records of those tests; many municipalities also require written records to be retained and produced on request. Regular testing, replacement of expired devices, and clear tenant instructions reduce both risk and liability.

Common areas, grounds and pest control

Maintenance obligations extend beyond individual units. Lobbies, stairwells, elevators, hallways, parking lots, and shared amenities must be kept at an acceptable level of cleanliness and safety. Seasonal tasks — snow removal, lawn care, eavestrough cleaning — and communal system upkeep fall to the owner or property manager unless the lease specifically allocates responsibility otherwise. Likewise, pest control is typically the landlord’s obligation when infestations affect the building. Being proactive in common-area maintenance prevents complaints and reduces risk of injury claims.

Right of entry: notice and timing

A landlord may enter a rental unit to inspect, repair, or show the property, but must provide proper notice. The standard framework requires written notice at least 24 hours in advance, a stated reason for entry, and a specific time window (commonly between 8 a.m. and 8 p.m.). Keep entry requests and tenant permissions in writing; clear communication reduces friction and demonstrates good faith if issues escalate.

Handling tenant damage, neglect and insurance

Landlords are usually responsible for normal wear and maintenance, but not for damage caused intentionally or by tenant neglect. Each situation should be assessed case by case; photographs, dated reports, and move-in condition records help determine responsibility. Encourage tenants to carry renter’s insurance and consider requiring proof of coverage when appropriate — it protects both parties and speeds claim resolution when accidents happen.

Practical playbook for landlords and on-site teams

1. Document everything. Create move-in checklists, log repair requests and resolutions, and retain alarm test records. Paper trails make remediation and insurance claims far easier.
   
   
2. Standardize preventative maintenance. Schedule inspections for roofs, HVAC, plumbing, and life-safety systems. Preventive upkeep costs less than emergency remediation.
   
   
3. Integrate communication. Use a single platform (property management software or CMMS) to receive tenant maintenance requests, assign technicians, and track closure and costs. This reduces missed requests and provides a searchable history.
   
   
4. Follow local rules for heating and alarms. Check municipal bylaws for heating season dates or higher minimums (some cities require 21°C or different seasonal windows) and adopt the stricter standard when in doubt.
   
   
5. Train and inform tenants. Provide simple instructions on alarm testing, how to report repairs, and what constitutes tenant responsibility. Clear expectations reduce misunderstandings.
   
   
6. Budget for replacements. Maintain a reserve for appliance and system replacement — delayed capital renewal is one of the fastest routes to avoidable emergency expenses.
   
   

When disputes happen: remedies and escalation

If a landlord fails to maintain the property, tenants have statutory remedies — they can report issues to local authorities or, in Ontario, seek help from the Landlord and Tenant Board or municipal bylaw enforcement, depending on the problem. Conversely, landlords should follow legal notice and repair procedures before taking stronger actions. Using impartial inspection reports and relying on the written tenancy agreement (while respecting statutory minimums) helps resolve disputes faster and fairly.

Maintenance is risk management

Good maintenance is more than compliance — it protects tenant health, extends asset life, and reduces long-term costs. For landlords in Ontario, meeting the standards set by provincial law and municipal bylaws, maintaining a clear record of action, and investing in preventative care will pay dividends in tenant retention and lower operational risk. If you’re unsure how the rules apply to your property, consult municipal resources or a legal professional — the cost of early guidance is small compared with the risk of non-compliance.
