Many tenants in Ontario worry about pests and bedbugs because infestations affect health, comfort, and the condition of a rental home. This article explains what penalties may apply when infestations occur, who is responsible for prevention and treatment, and how renters can document problems and use official forms and the Landlord and Tenant Board to seek remedies. It guides tenants through practical steps — from notifying your landlord in writing and requesting repairs to when to involve public health or file an application — using plain language and tenant-focused examples. Whether you’re dealing with an initial infestation or a persistent problem, this guide helps you understand your rights, timelines, and evidence to collect.
Who is responsible and what penalties apply?
Under Ontario law, landlords must provide and maintain rental units in a state of repair and fit for habitation, which generally includes treating pest and bedbug infestations promptly. Tenants should report infestations in writing and allow reasonable access for treatment. The Residential Tenancies Act, 2006 sets the legal duties and remedies for both landlords and tenants.[1]
Possible penalties and remedies
- Orders to repair or remediate the unit, issued by the Landlord and Tenant Board or a health inspector.
- Compensation or rent abatement if a unit becomes uninhabitable and the landlord fails to act.
- Applications to end a tenancy or orders for compliance if infestations are severe or repeated.
- Municipal or public health bylaw violations and orders when infestations risk community health.
When a tenant may be held responsible
Tenants can be held liable if an infestation is caused by their actions (for example, hoarding or a failure to follow agreed pest-control steps) and they ignore written requests to address the problem. If a landlord believes a tenant caused an infestation, the landlord may use notices or an application to the Landlord and Tenant Board to seek remedies and costs.[2]
- Refusal to allow reasonable access for treatment can be treated as interference and may lead to an order.
- Persistent failure to follow agreed pest-prevention steps after written warnings.
Practical tenant actions
Tenants should act quickly: notify the landlord in writing, keep a dated record of all communications, take photos, keep receipts for cleaning or treatment, and get written reports from pest-control professionals where possible. If the landlord does not act, tenants can contact public health or apply to the Landlord and Tenant Board for orders or compensation.

Forms tenants and landlords commonly use
Ontario does not use a single "pest" eviction form; actions commonly start with written notices and can proceed to an application to the Landlord and Tenant Board using official forms. Important official forms and where they are used are listed below.[3]
Notice to End your Tenancy for Causing Serious Problems (Form N5)
The N5 notice is used when a landlord alleges the tenant has caused serious problems that interfere with reasonable enjoyment or cause damage. Example: if a tenant repeatedly refuses to follow agreed pest-control steps and an infestation spreads, a landlord may serve an N5 before applying to the Board. Tenants who receive an N5 should respond in writing and seek advice; timelines for remedy or termination are included on the notice.
Landlord and Tenant Board application forms
The Landlord and Tenant Board provides application and response forms for disputes (including requests for orders to repair, compensation, or termination). If the landlord or tenant cannot resolve an infestation, either party can file an application asking the Board to decide. The Board will set a hearing where both sides can present evidence, such as photos, pest-control invoices, communications, and witness statements.
FAQ
- Who usually pays for pest or bedbug treatment?
- Landlords are generally responsible for arranging and paying for pest control to maintain habitability, unless the infestation can be clearly shown to be caused by the tenant's actions and a Board orders otherwise.
- Can a landlord evict me for bedbugs?
- A landlord can apply to end a tenancy if infestations are severe and the tenant has breached obligations, but the Board will consider evidence, opportunity to remediate, and human-rights or public-health factors before making an order.
- What evidence helps when making a complaint?
- Use dated photos, pest-control reports, invoices, a log of communications with the landlord, and witness statements to support your case.
How-To
- Notify your landlord in writing describing the infestation, dates, and requested actions.
- Document the problem with photos, videos, and a dated log of sightings and communications.

- Allow reasonable access for inspections and pest-control visits where required under your lease or local law.
- Keep invoices, receipts, and reports from pest-control professionals in case you seek compensation or a Board order.
