Subletting and Assignments When Moving Out in Ontario

Moving out means thinking about whether to sublet or assign your rental agreement. Both options let a tenant transfer possession to someone else, but they work differently and have different responsibilities under Ontario law. This guide explains in clear language how subletting and assignments work for renters in Ontario, when landlord consent is needed, what paperwork and timelines to follow, and practical steps to protect your deposit and avoid disputes. It also points to official forms and the Landlord and Tenant Board so you can file or respond to an application if needed. Use these tips to plan a smooth move-out and keep your rights as a tenant.

Understanding assignments and subletting in Ontario

In Ontario a sublet is when a tenant lets someone else live in the unit while remaining the tenant on the lease; an assignment transfers the tenancy so the replacement becomes the tenant and you usually move out. The rules come from the Residential Tenancies Act, 2006^[1] and disputes are handled by the Landlord and Tenant Board. You should review your lease and the Act before offering the unit to anyone.

• Rent responsibility: If you sublet, you remain responsible to the landlord for rent and any damage unless a written agreement says otherwise.
• Full transfer: An assignment makes the new occupant the tenant when you move out and generally relieves you of future obligations by agreement.
• Consent: Both sublets and assignments usually require landlord consent, which cannot be unreasonably withheld under provincial rules.

Landlord consent, forms and common scenarios

Many leases include clauses about subletting or assigning; some require the tenant to get written consent first. If the landlord asks for references, credit checks or a meeting, provide reasonable information and keep records. If the landlord refuses consent and you believe it is unreasonable, you can apply to the Landlord and Tenant Board for a decision. The Board and its forms are available on the Tribunal site and the LTB forms page can help you start an application^[2].

Common official resources and forms you may need:

• Application to the Landlord and Tenant Board (general application) — used when a tenant or landlord asks the LTB to resolve a dispute, for example if consent to sublet or assign is refused and you want a binding decision. Example: you ask the Board to order the landlord to allow an assignment after they refuse without reasonable grounds.
• Document templates and correspondence — keep a dated copy of any written consent, screening forms, signed assignment or sublet agreement and rent receipts to show the Board if needed.

FAQ

Can my landlord refuse a sublet or assignment?

They cannot unreasonably withhold consent under the Residential Tenancies Act, 2006, though they may request references or reasonable screening; if you dispute a refusal, you can apply to the Landlord and Tenant Board for a decision.

Am I still responsible for damage or unpaid rent if I sublet?

Yes. When you sublet you generally remain responsible to the landlord for rent and damages unless you have completed a formal assignment and the landlord has agreed to release you in writing.

What if I need to leave before the lease ends?

Try to assign the tenancy or arrange a sublet with the landlords consent; for practical moving and exit steps see Moving Out Tips: A Tenant''s Guide to a Smooth Rental Exit and the guide What to Do If You Need to Leave Your Rental Before the Lease Expires.
