Maintenance disputes represent one of the most common and contentious areas of Ontario's rental housing system. From leaky roofs and pest infestations to heating failures and structural issues, the question of who is responsible for what—and when—creates a complex web of legal obligations that both landlords and tenants must navigate carefully.
Understanding these obligations is crucial for maintaining healthy rental relationships and avoiding costly legal disputes at the Landlord and Tenant Board.
The Foundation: Section 20 of the Residential Tenancies Act
The cornerstone of maintenance law in Ontario is Section 20(1) of the Residential Tenancies Act, which establishes the landlord's fundamental obligation:
"A landlord is responsible for providing and maintaining a residential complex, including the rental units in it, in a good state of repair and fit for habitation and for complying with health, safety, housing and maintenance standards."
This seemingly straightforward provision encompasses a vast range of responsibilities, from basic structural integrity to compliance with municipal bylaws and health standards.
What "Good State of Repair" Means
The LTB interprets "good state of repair" as requiring landlords to:
- Maintain structural integrity of the building and rental units
- Ensure all systems function properly (plumbing, electrical, heating, ventilation)
- Address health and safety hazards promptly and effectively
- Comply with applicable codes and standards (building codes, fire codes, health standards)
- Respond reasonably and timely to maintenance issues when notified
Successful Tenant Applications: When Landlords Fail
Recent LTB decisions demonstrate the serious consequences when landlords fail to meet their maintenance obligations.
Severe Water Damage Cases
In neilson-v-clv-group-20240510, tenants endured water damage for 20 months from late March 2021 until November 2022. They had to use buckets to catch water leaking into their bedroom, with walls becoming severely compromised by February 2022. The LTB found the landlord breached Section 20 obligations and awarded $4,725 in rent abatement.
W.V.-v-M.P.-20181121 shows how maintenance failures can escalate dramatically. Water damage in the tenant's bedroom on April 15, 2018, led to flooding in the basement on May 2, followed by electrical problems on May 30 and June 1. The City issued a Property Standards Order on July 13, 2018, but the landlord's response was "woefully inadequate." The tenant received $1,100 in rent abatement and the landlord was ordered to complete repairs by specified deadlines.
Pest Infestation Disasters
Pest control failures can result in substantial awards. In G.A.O-and-H.A-v-H.R-20181114, tenants suffered from bedbug and cockroach infestations for nearly a year. Despite providing medical letters documenting the health impacts, the landlord's superintendent told tenants "if they didn't like the infestation, they should move out." The LTB awarded $9,741.15 (75% of 10 months' rent) plus application fees.
AD-v-DPL-20160519 involved a bedbug infestation that persisted for three months despite the landlord's initial quick response. The tenant and her daughter were regularly bitten, their bedding and furniture were affected, and they ultimately had to vacate. The LTB awarded $1,640.80 including rent abatement, property replacement costs, and cleaning expenses.
Systemic Maintenance Failures
AP-and-EQ-v-PD1-20160201 demonstrates how multiple maintenance failures can compound. The rental unit had "serious maintenance problems from the beginning of the tenancy," including failure to provide potable water. Combined with harassment and illegal entry, the landlord's conduct resulted in $4,800 in rent abatement plus $922 in compensation.
Heating and Essential Services
ryan-v-homestead-land-holdings-limited-20240704 involved heating system failures that tenants reported starting in January 2021. The landlord made 12 visits but failed to properly diagnose the problem until a municipal complaint was filed. The LTB found the landlord's response "lacked sufficient thoroughness" and awarded $1,410.08 in rent abatement plus $18.06 for additional electricity costs.
When Landlords Successfully Defend
Not all maintenance applications succeed. The LTB carefully examines whether landlords have met their obligations through reasonable and timely responses.
Prompt and Effective Response
BD-v-LG-20180501 shows how landlords can successfully defend maintenance claims. When water damage occurred in March 2017, the landlord "responded immediately and arranged for repairs" despite being out of the country. The LTB found the landlord took "reasonable steps to address the issues" and was not liable for latent defects of which they had no knowledge.
cardella-v-freiman-investments-inc-20240913 demonstrates successful landlord response to maintenance issues. When tenants reported a leak, the landlord "responded promptly," "ordered replacement parts without delay," and "coordinated work to avoid leaving Tenant without kitchen." The LTB found no breach of maintenance obligations.
Tenant Interference with Repairs
VC-v-MTII-20180130 illustrates how tenant conduct can absolve landlords of maintenance obligations. The tenant's "aggressive and verbally abusive behavior" toward landlord staff, including calling the superintendent's wife a "lying bitch" and leaving threatening voicemails, interfered with the landlord's ability to respond to maintenance issues. The LTB dismissed the tenant's application, finding the landlord could not be held responsible for maintenance failures caused by the tenant's conduct.
Reasonable Pest Control Efforts
Waugh-v-The-Effort-Trust-Company-20211116 shows successful landlord pest control response. When tenants reported rodent problems, the landlord hired an appropriate pest control company (RATLAB) within 2-3 weeks and implemented reasonable treatment. Since tenants didn't indicate the problem persisted after treatment, the LTB found the landlord met their maintenance obligations.
The Reasonableness Standard
The LTB applies a "reasonableness" standard when evaluating maintenance disputes, considering several key factors:
Timeliness of Response
Landlords must respond to maintenance issues within a reasonable time after being notified. What constitutes "reasonable" depends on:
- Urgency of the issue (emergency repairs vs. cosmetic concerns)
- Complexity of the problem (simple fixes vs. major renovations)
- Availability of contractors and materials
- Seasonal factors (weather-dependent repairs)
- Tenant cooperation in providing access
Effectiveness of Response
The landlord's response must be appropriate to address the underlying problem, not just provide temporary fixes. In Canoglu-v-Capreit-20220106, the landlord was aware of water leaks in July 2019 and December 2020 but didn't complete necessary repairs until May 2021. The LTB found the landlord's "COVID-19 emergency work policy was not a reasonable excuse for the delay" and awarded $2,160 in rent abatement.
Communication and Coordination
Successful landlords maintain clear communication with tenants about repair timelines and coordinate work to minimize disruption. Poor communication can turn minor issues into major disputes.
Common Maintenance Issues and LTB Approaches
Water Damage and Leaks
Water-related issues are among the most serious maintenance concerns due to their potential for structural damage and health hazards.
Landlord Obligations:
- Investigate and identify the source of leaks promptly
- Complete repairs in a reasonable timeframe
- Address any resulting damage (drywall, flooring, personal property)
- Prevent mold growth through proper remediation
Tenant Responsibilities:
- Report water issues immediately upon discovery
- Provide reasonable access for investigation and repairs
- Take reasonable steps to minimize damage (using buckets, moving belongings)
Pest Control
Pest infestations require coordinated responses between landlords and tenants.
Landlord Obligations:
- Hire qualified pest control professionals
- Follow through with recommended treatment schedules
- Address structural issues that allow pest entry
- Coordinate building-wide treatment when necessary
Tenant Responsibilities:
- Report pest sightings promptly
- Cooperate with pest control treatments
- Maintain reasonable cleanliness standards
- Follow pest control professional recommendations
Heating and Cooling Systems
HVAC issues can render units uninhabitable, especially during extreme weather.
Landlord Obligations:
- Maintain heating systems in working order
- Respond urgently to heating failures during cold weather
- Ensure adequate ventilation and air quality
- Replace or repair systems that cannot be effectively maintained
Tenant Responsibilities:
- Use heating systems reasonably and as intended
- Report heating issues promptly
- Provide access for system maintenance and repairs
- Avoid blocking vents or interfering with system operation
Tenant Rights and Remedies
When landlords fail to meet maintenance obligations, tenants have several remedies available through T6 applications:
Rent Abatement
The most common remedy is rent abatement—a reduction in rent to reflect the diminished value of the rental unit during the maintenance issue period.
Calculation Factors:
- Severity of the issue (minor inconvenience vs. uninhabitable conditions)
- Duration of the problem (days vs. months)
- Portion of unit affected (single room vs. entire unit)
- Impact on daily life (cosmetic issues vs. health and safety concerns)
Typical Abatement Ranges:
- Minor issues: 5-15% of monthly rent
- Moderate issues: 15-50% of monthly rent
- Severe issues: 50-100% of monthly rent
- Uninhabitable conditions: 100% rent abatement
Out-of-Pocket Expenses
Tenants can recover reasonable expenses incurred due to landlord maintenance failures:
- Temporary accommodation costs during major repairs
- Property replacement for items damaged by maintenance issues
- Professional cleaning required due to landlord failures
- Additional utility costs (space heaters during heating failures)
Repair Orders
The LTB can order landlords to complete specific repairs by specified deadlines, with consequences for non-compliance:
- Rent abatement continuing until repairs are completed
- Authorization for tenant-arranged repairs with costs deducted from rent
- Additional penalties for continued non-compliance
Landlord Strategies for Compliance

Key Takeaways
The maintenance obligations system in Ontario attempts to balance landlord property rights with tenant habitability rights. Key principles to remember:
- Landlords have primary responsibility for maintaining rental properties in good repair
- Reasonableness and timeliness are key standards for evaluating landlord responses
- Tenant cooperation is essential for effective maintenance management
- Documentation is crucial for both preventing and resolving disputes
- Professional help is valuable for complex maintenance issues and legal disputes
- Prevention is better than cure—proactive maintenance prevents most serious disputes
Conclusion
Navigating Ontario's maintenance obligations requires understanding both legal requirements and practical realities. While the law clearly places primary responsibility on landlords to maintain rental properties, successful maintenance management requires cooperation from both parties.
For landlords, the message is clear: invest in proper maintenance systems, respond promptly to tenant concerns, and document your efforts thoroughly. The cost of proper maintenance is almost always less than the cost of LTB disputes, rent abatements, and tenant turnover.
For tenants, understanding your rights empowers you to advocate effectively for proper maintenance while fulfilling your own obligations. Prompt reporting, reasonable cooperation, and proper documentation protect your interests and help ensure your rental unit remains safe and habitable.
The maintenance maze may be complex, but with proper understanding and good faith efforts from both parties, it can be navigated successfully. The goal is not just legal compliance, but creating rental relationships that work for everyone involved.
As Ontario's rental market continues to evolve, maintenance obligations remain a cornerstone of tenant protection and property preservation. Both landlords and tenants benefit from understanding these obligations and working together to maintain safe, healthy, and habitable rental housing for all.
