What Landlords Are Not Allowed to Do in ON | Legal Limits Explained

The boundaries placed on landlords in Ontario are primarily established by the Residential Tenancies Act, 2006, which governs most residential rental agreements across the province. This legislation outlines tenant protections, landlord obligations, and enforcement procedures, creating a balanced framework for rental relationships.

Oversight is provided by the Landlord and Tenant Board, which adjudicates disputes and ensures compliance with the law. Both tenants and landlords are expected to operate within the provisions of the Act, and violations may result in legal consequences, including financial penalties or enforceable orders.

Policy direction and regulatory updates are further supported by the Ontario Ministry of Municipal Affairs and Housing, which plays a central role in maintaining housing standards and adapting legislation to current market realities.

Understanding this legal foundation is essential because it defines not only tenant rights but also the limits landlords must respect in every aspect of property management.

One of the clearest restrictions placed on landlords relates to tenant privacy. Landlords are not permitted to enter a rental unit at will. Except in cases of emergency, they must provide proper notice before accessing the property.

The law requires at least 24 hours’ written notice, specifying the reason for entry and the intended time. This entry must occur within reasonable hours. According to the Landlord and Tenant Board, failure to comply with these requirements may constitute interference with a tenant’s reasonable enjoyment of their home.

This limitation reflects a broader principle embedded in Ontario housing law: once a property is rented, it becomes the tenant’s lawful living space, and that right must be respected.

Eviction is one of the most tightly regulated areas of landlord activity in Ontario. Landlords are not allowed to remove tenants without following the formal legal process.

The Residential Tenancies Act requires landlords to provide valid grounds for eviction, issue proper notice, and obtain an eviction order through the Landlord and Tenant Board. According to the Board, tenants have the right to challenge eviction applications, present evidence, and participate in hearings before any decision is enforced.

Actions such as changing locks, removing belongings, or forcing tenants out without an order are considered illegal. These safeguards ensure that tenants are protected from sudden displacement and that disputes are resolved through due process.

Another critical area where landlords face legal limits is rent control. Landlords are not allowed to increase rent arbitrarily or without following established guidelines.

According to the Ontario Ministry of Municipal Affairs and Housing, rent increases must adhere to annual limits set by the province and can generally only occur once every 12 months. Landlords are also required to provide at least 90 days’ written notice before implementing any increase.

Economic data from [Statistics Canada](https://www150.statcan.gc.ca/n1/pub/12-539-x/2019001/ensuring-assurer-eng.htm) informs these guidelines, ensuring that rent adjustments align with broader inflation trends. These regulations protect tenants from sudden financial pressure and contribute to housing stability in a competitive market.

Landlords in Ontario are not allowed to discriminate against tenants under any circumstances covered by law. The [Ontario Human Rights Code](https://www.canlii.org/en/on/laws/stat/rso-1990-c-h19/latest/rso-1990-c-h19.html) prohibits discrimination based on race, religion, gender, disability, family status, and other protected characteristics.

According to the [Ontario Human Rights Commission](https://www.ontario.ca/laws/statute/90h19), housing providers must ensure equal treatment throughout the rental process, from advertising and tenant selection to lease enforcement. This means landlords cannot refuse applications, impose different terms, or create barriers based on personal characteristics unrelated to tenancy obligations.

Landlords are not allowed to ignore their responsibility to maintain rental properties. The law requires that units remain in a good state of repair and comply with health, safety, and housing standards.

According to the Ontario Ministry of Municipal Affairs and Housing, maintenance obligations apply regardless of the rent charged or the terms of the lease. Tenants cannot be asked to waive these rights.

Research from the [Canada Mortgage and Housing Corporation](https://publications.gc.ca/collections/collection_2023/schl-cmhc/NH70-2-2023-2-eng.pdf) highlights the direct relationship between housing quality and occupant well-being, reinforcing the importance of proper maintenance.

Failure to address repairs can result in tenant applications to the Landlord and Tenant Board, which may order repairs or compensation.

Harassment and Interference with Tenant Rights

Landlords are not allowed to harass, intimidate, or pressure tenants. This includes excessive communication, threats, or actions intended to force tenants to leave.

The concept of “reasonable enjoyment” under the Residential Tenancies Act protects tenants from such behavior. According to the Landlord and Tenant Board, interference with this right can lead to legal action and compensation orders.

This restriction ensures that tenants can live peacefully without fear of undue pressure or disruption.

Another clear legal limitation is the prohibition against withholding essential services. Landlords are not allowed to shut off utilities such as heat, water, or electricity, even in cases of dispute.

Ontario regulations classify these services as essential to habitability. Interrupting them can create unsafe living conditions and is treated as a serious violation.

This rule ensures that tenants are not subjected to coercive tactics that compromise their health or safety.

Landlords are also restricted in how they handle deposits. In Ontario, they are not allowed to collect arbitrary or excessive deposits beyond what is permitted by law.

Typically, only last month’s rent can be collected as a deposit, and it must be applied appropriately. Misusing these funds or demanding additional deposits outside legal allowances is prohibited.

Clear financial documentation supported by structured systems like Platuni helps landlords remain compliant and reduces disputes related to payments and deposits.

Once a lease agreement is in place, landlords are not allowed to change its terms without tenant consent. This includes changes to rent, services, or occupancy conditions.

The Residential Tenancies Act ensures that lease agreements remain stable unless both parties agree to modifications. This protects tenants from sudden or unfair changes that could affect their housing security.

A significant number of landlord-tenant disputes arise not from intentional violations but from poor record-keeping and unclear communication. Proper documentation of notices, agreements, and interactions is essential.

Structured operational platforms like Platuni demonstrate how consistent workflows, centralized communication, and clear documentation can help landlords stay compliant while improving tenant relationships. By aligning operational practices with legal requirements, landlords can minimize risk and create more transparent rental environments.

Ontario’s strict limitations on landlord behavior are not arbitrary. They are part of a broader effort to ensure housing stability in a high-demand market.

According to Statistics Canada, rising rental demand and affordability challenges have made tenant protections increasingly important. Legal frameworks like the Residential Tenancies Act help maintain balance by preventing abuse while supporting fair property management practices.

This context underscores why understanding what landlords are not allowed to do in Ontario is essential for both tenants and landlords.
