Subletting can help an Ontario tenant manage a temporary move, but doing it without the landlord's required consent can create serious risks. A renter may remain responsible for the lease, rent, and damage caused by an unauthorized subtenant, even when the tenant did not cause the damage personally. The outcome depends on the rental agreement, what permission was requested, the condition of the unit, and the evidence available. This guide explains tenant liability for unauthorized subletting damages in Ontario, how the Residential Tenancies Act, 2006 applies, and what steps renters can take after receiving a notice or application. It also explains the Landlord and Tenant Board process in plain language so tenants can respond within the required deadlines.
What counts as an unauthorized sublet in Ontario?
A sublet generally occurs when a tenant temporarily gives another person possession of the rental unit while keeping the right to return and retaining the tenancy agreement. Ontario tenants usually need the landlord's consent before subletting. Consent cannot be withheld arbitrarily or unreasonably, but a tenant should obtain it in writing before handing over the unit. An occupant who simply lives with the tenant may not be a subtenant, so the facts and the agreement matter.
The Residential Tenancies Act, 2006 sets rules for assignments and sublets, while the Obligations of Landlords and Tenants: Rights and Responsibilities Explained guide provides broader information about complying with a rental agreement.
Who may be responsible for damage?
As the named tenant, you generally remain responsible for complying with the tenancy agreement and for undue damage caused by you, another occupant, or a person you permit to enter the unit. Ordinary wear and tear is different from damage. A landlord may seek compensation when the damage is beyond normal use and is connected to the tenant's conduct or the conduct of someone the tenant allowed into the rental unit.
Unauthorized subletting can create additional issues, including unpaid rent, damage to the unit, rule violations, or a dispute about who is entitled to occupy the home. The landlord may ask the Landlord and Tenant Board to end the tenancy or order compensation. The tenant can challenge the claim by explaining the circumstances and presenting evidence about the condition of the unit, responsibility for the damage, and any steps taken to obtain consent.
- Keep the signed lease, written consent requests, messages, inspection records, photographs, videos, and repair receipts.
- Check whether the claimed amount is supported by invoices, receipts, estimates, or other proof of the actual loss.
- Separate normal wear and tear from damage that a reasonable person would consider excessive.
What notices or applications might be used?
A landlord must use the appropriate process rather than simply taking money from a tenant's deposit or changing the locks. Depending on the facts, the landlord may serve a notice and apply to the Landlord and Tenant Board. The LTB's official forms page identifies current forms and filing instructions, including forms that may apply to unauthorized occupancy, damage, and ending a tenancy.
- Form A2 may be used by a landlord asking the LTB to determine whether an occupant is an unauthorized occupant.
- Form N5 may be used for substantial interference, damage, or overcrowding concerns where the statutory requirements are met.
- Form N7 may apply to serious problems involving damage or interference, depending on the facts and legal requirements.
- Form L2 is the landlord's application to the LTB to end a tenancy and evict a tenant, or to collect certain amounts after a notice.
These forms do not prove that a tenant is liable. They begin a legal process in which the landlord must establish the legal grounds and supporting facts. A tenant should read every page, note the hearing date, and follow the response or filing instructions.

How tenants can respond to a damage claim
Do not ignore a notice, application, or hearing package. Gather the agreement, communications about permission, the subtenant's contact details, move-in and move-out photographs, inspection reports, and proof of payments. Ask the landlord in writing for a detailed breakdown of the claimed damage and copies of invoices or estimates. Keep communication factual and avoid admitting responsibility before reviewing the evidence.
- Record every deadline and hearing date as soon as you receive the documents.
- Submit a response or application through the LTB process when the instructions require it.
- Organize evidence in date order and label each photograph, message, receipt, and inspection record.
- Attend the hearing and explain why the claimed damage, amount, or termination ground is disputed.

Can a landlord deduct the claim from a deposit?
Ontario generally limits security deposits to a rent deposit and a refundable key deposit where permitted. A landlord cannot use a rent deposit as a general damage deposit. A claim for damage is normally pursued through the proper LTB process or another legally available process, rather than by simply keeping a rent deposit. Tenants should keep proof of the deposit and ask for a receipt or written explanation for any disputed amount.
