Living with roommates in Quebec often means sharing rent, bills and responsibilities, and when one person decides to leave it can raise practical and legal questions for the remaining tenants. This guide explains tenant-focused steps for giving and responding to a roommate move-out notice, how notice timing and the lease type affect responsibility for rent, and what to do if a landlord or co-tenant seeks a replacement or compensation. It covers communicating with your landlord, documenting agreements, using official forms and when to contact the Tribunal administratif du logement for disputes. The goal is to help renters understand their rights, reduce unexpected costs, and learn clear action steps to protect their credit and tenancy record.
Who is responsible when a roommate moves out?
When a rental agreement lists multiple tenants jointly, each co-tenant is typically responsible for the full rent under Quebec rules; one roommate leaving does not automatically remove their legal obligation unless the landlord agrees to a release or a new lease is signed.[1]
- If you share a joint lease, you and your co-tenants can remain jointly responsible for rent and damages.
- Give written notice to your landlord and to the departing roommate to document the date they plan to move out.
- Keep copies of any agreements, emails and receipts that show who paid rent or agreed to a replacement.
Notice timing and written notice
Quebec law treats leases and terminations under civil rules and tribunal practice; your obligations depend on whether the lease is fixed-term or periodic and on any written agreement with the landlord.[2] If a roommate wants to leave before a fixed-term lease ends, ask the landlord for a written release or to accept a replacement tenant to avoid continued liability.
How to protect yourself and next steps
- Ask for a written release from the landlord that clearly removes the departing roommate from the lease and liability.
- Collect or keep rent receipts showing who paid what and when to prevent disputes about unpaid rent.
- Propose a replacement tenant and document the landlord's consent in writing to avoid future claims.

When to apply to the Tribunal administratif du logement
If the landlord and tenants cannot agree — for example if the landlord refuses a reasonable replacement or seeks unpaid rent you dispute — you may file an application with the Tribunal administratif du logement to resolve responsibility, compensation or eviction questions.[1] The tribunal offers online forms and guidance for filing a complaint or requesting a hearing.[3]
FAQ
- Do I need to give written notice if my roommate moves out?
- It depends on your lease. If your names are on a joint lease, notify the landlord in writing as soon as possible and seek a written release; otherwise you may still be liable for rent.
- Can a landlord charge me for a roommate’s unpaid rent?
- Yes, if the lease lists you as a co-tenant you can be held responsible for unpaid rent until the lease ends or the landlord authorizes a replacement or signs a new lease.
- What if my roommate leaves without telling anyone?
- Document communications and payments, inform the landlord immediately, and consider asking for a formal release or a rent adjustment; if the landlord pursues collection, you can raise your evidence before the Tribunal.
How-To
- Write a clear dated notice stating when the roommate will vacate and distribute it to the landlord and co-tenants.
- Check your lease terms for fixed-term obligations and any clauses about subletting or replacements.
- Find and propose a qualified replacement tenant and get the landlord’s written approval.
- Keep copies of all agreements, receipts and communications confirming payments and releases.
- If a dispute remains, file an application with the Tribunal administratif du logement and attend any hearing scheduled.
