Subsidized Housing: Roommate Rules in Quebec

Roommates & Shared Housing Quebec 4 min read · published March 29, 2026 Flag of Quebec

Living in subsidized housing in Quebec comes with specific rules about adding or changing roommates, sharing rent, and notifying housing authorities. As a tenant or renter you need to know how public housing and subsidy programs treat household composition, income reporting, and eligibility because mistakes can affect your subsidy and your tenancy. This guide explains common roommate scenarios in plain language, including when you must get written permission, how shared costs are treated, and what to do if a roommate leaves or causes problems. It also points to official Quebec resources and forms so you can take steps like notifying the landlord, documenting changes, or applying to the Tribunal administratif du logement[1].

How subsidized housing programs treat roommates

Subsidy programs and social housing providers look at the people who live in the unit when calculating assistance. That means adding or removing a roommate can change your household income, which may increase or reduce your subsidy. In many programs you must report household composition changes in writing to the housing provider or the subsidy office right away; failure to report can lead to repayment demands or loss of benefits. When in doubt, ask your housing office for the specific rule that applies to your file.

Keep clear, dated records whenever a roommate moves in or out.

Adding or removing a roommate: practical steps

  • Serve written notice to your landlord or housing provider explaining the change and the move-in/move-out date.
  • Submit household information or required forms to the subsidy office or Société d'habitation du Québec to update eligibility and income details.
  • Agree in writing who pays rent, utilities, and any security deposit adjustments to avoid disputes later.
  • Keep copies of IDs, income documents, and any signed agreements showing who lives in the unit.
Failing to report household changes can result in subsidy recovery or tenancy sanctions.

When the lease or subsidy policy requires permission

Some leases and social housing rules require the tenant to get written permission before adding a roommate. If a lease says no subletting or limits occupants, adding an extra person without permission may breach the lease. If your subsidy or housing agreement lists household size limits, speak with your landlord or the housing office before anyone moves in. If you need help interpreting your rights and obligations, consult provincial resources or seek advice from the housing authority.

Roommate disputes, repairs, and safety concerns

If a roommate causes serious problems (damage, illegal activity, or safety risks), tell your landlord and document incidents with dates and photos. For habitability issues like heating, water, pests, or repairs, the landlord remains responsible for maintaining the unit even if roommates share obligations for payment[2]. If the landlord fails to act, you can file an application with the Tribunal administratif du logement to request repairs or remedies.

Documenting conversations, notices, and repair requests strengthens your position in disputes.

Money matters: rent, deposits and shared payments

Decide and document who is responsible for the rent each month. If you collect money from a roommate, keep receipts and written records. For guidance on deposits and what landlords can require, see Understanding Rental Deposits: What Tenants Need to Know. If a roommate leaves owing money, you may still be responsible to the landlord depending on the lease.

Legal help and formal complaints

If you cannot resolve a dispute with your landlord or housing provider, the Tribunal administratif du logement handles residential tenancy disputes in Quebec[1]. You can apply to the Tribunal for issues such as unauthorized occupants, rent adjustments tied to household composition, or eviction matters. Follow the Tribunal's application process and attach your supporting documents: lease copies, notices, receipts, and photos.

FAQ

Can I add a roommate in subsidized housing in Quebec?
Usually you must notify the landlord and the subsidy office; adding a roommate can change your household income and affect your subsidy, so get permission if your lease or program requires it.
Will a roommate share responsibility for rent and damage?
It depends on your lease and whether the roommate is on the lease; anyone named on the lease typically shares legal responsibility, so put payment and liability agreements in writing.
Do I have to report a roommate leaving?
Yes. Report household composition changes to your housing provider and subsidy office so your file is accurate and you avoid repayment or eligibility problems.
How do I challenge a landlord decision about roommates?
If you cannot resolve matters directly, you can apply to the Tribunal administratif du logement for a ruling, supplying evidence and copies of notices and agreements.

How-To

  1. Check your lease and subsidy rules to see whether written permission is required.
  2. Serve written notice to your landlord with the roommate's move-in or move-out date and any requested documents.
  3. Gather proof of income, ID, and a signed roommate agreement showing payment responsibilities.
  4. Submit required forms to the subsidy office or housing provider and ask for written confirmation of the update.
  5. Keep copies of all submissions and contact the Tribunal administratif du logement if you need a formal decision.
