Ontario Maintenance Obligations: Landlord Responsibilities and Habitability Standards

Ontario landlords have a broad legal obligation to maintain rental properties in a good state of repair, fit for habitation, and compliant with all health, safety, housing, and maintenance standards. These obligations are set out in the Residential Tenancies Act (RTA) and detailed in Ontario Regulation 517/06 (Maintenance Standards).

Landlord's Core Maintenance Obligation

Under RTA §20, the landlord is responsible for:

• Providing and maintaining the rental unit in a good state of repair
• Ensuring the unit is fit for habitation
• Complying with health, safety, housing, and maintenance standards
• Maintaining the residential complex (common areas, grounds, parking) in a good state of repair

This obligation applies regardless of whether the tenant was aware of a state of disrepair before moving in.

Specific Maintenance Standards (O. Reg. 517/06)

Ontario Regulation 517/06 sets detailed requirements for residential rental properties:

Heating

Plumbing and Water

• Hot and cold running water in the kitchen and bathroom
• Hot water temperature adequate for normal household use
• All plumbing fixtures in good working order
• No leaks or drainage problems

Electrical Systems

• Adequate electrical power for normal use
• All outlets, switches, and fixtures in safe working order
• Proper lighting in common areas (hallways, stairwells, parking areas)

Structural Integrity

• Walls, ceilings, and floors in good condition (no holes, cracks, or water damage)
• Roofs and exterior walls weather-tight
• Windows and doors in good repair with functioning locks
• Stairways, railings, and balconies structurally sound

Appliances

• All appliances provided by the landlord must be maintained in good working order
• This includes stoves, refrigerators, dishwashers, washers, dryers, and any other appliances included with the unit

Pest Control

• Landlords must eliminate infestations of insects (cockroaches, bed bugs) and rodents
• Regular pest control measures must be taken
• The landlord is responsible even if the tenant's actions contributed to the infestation (though the landlord may seek compensation from the tenant)

Safety

• Smoke detectors on every storey and outside sleeping areas
• Carbon monoxide detectors where required by the Ontario Fire Code
• Fire exits clear and accessible
• Proper ventilation in all habitable spaces

Tenant Remedies for Maintenance Issues

If a landlord fails to maintain the property, tenants have several options:

1. File a T6 Application with the LTB

• Tenants can apply to the LTB for an order requiring the landlord to do repairs
• The LTB may order repairs to be completed within a specific timeline
• The LTB may also order a rent reduction for the period the unit was in disrepair

2. Contact Municipal Property Standards

• Tenants can file a complaint with their municipal property standards or bylaw enforcement office
• An inspector will investigate and may issue work orders to the landlord
• Non-compliance with work orders can result in fines

3. Contact Public Health

• For health-related maintenance issues (mold, pests, sewage, lack of heat)
• The local public health unit can investigate and issue orders

Tenant Obligations Tenants also have maintenance responsibilities:

• Keep the unit reasonably clean
• Repair or pay for damage caused by the tenant, their guests, or pets (beyond normal wear and tear)
• Not willfully or negligently cause damage
• Promptly notify the landlord of maintenance issues

What is "Normal Wear and Tear"?

Landlords cannot charge tenants for normal wear and tear. Examples:

Emergency Repairs

For emergency repairs (burst pipes, no heat in winter, electrical hazards), landlords should:

1. Respond immediately to the tenant's report
2. Arrange emergency repair services
3. If the unit is temporarily uninhabitable, assist with alternative accommodation
4. The LTB may authorize a tenant to arrange emergency repairs and deduct costs if the landlord is unresponsive

Best Practices for Ontario Landlords

1. Schedule regular inspections — With proper 24-hour written notice (Form N5 for entry)
2. Respond promptly to repair requests — Document all requests and responses
3. Hire licensed contractors — For electrical, plumbing, and structural work
4. Maintain heating systems — Annual furnace maintenance before heating season
5. Keep pest control records — Regular treatment schedules and inspection records
6. Budget for maintenance — Set aside funds for preventive and reactive maintenance
