Roommates and Shared Housing Rights for Quebec Tenants

Roommates & Shared Housing Quebec published July 01, 2025

Living with roommates in Quebec offers flexibility and can make housing more affordable, but it’s important to know your legal rights and obligations. Quebec laws surrounding shared housing can be complex, especially regarding who is responsible for the lease, rent payments, and potential conflicts. This guide provides up-to-date, plain language information to help tenants feel secure when renting with others in Quebec.

Types of Roommate Arrangements in Quebec

Roommate and shared housing situations usually fall into two categories:

Co-tenants: Everyone who signs the lease has equal rights and responsibilities to the landlord. All names appear on the lease agreement.
Subtenants or Occupants: Only some people sign the lease, and others join later or informally. Subtenants often have less direct legal protection.

Knowing your official status as a tenant is crucial, because it affects your legal rights and how any issues with rent, eviction, or moving out are handled.

Leases, Legal Responsibilities, and Rent in Shared Housing

Quebec tenancy law is based on the Civil Code of Quebec^[1]. If you and your roommates sign the lease, you are each responsible to the landlord for rent and property care. This means if one tenant stops paying, the others may have to pay the difference.

It’s best practice for all roommates to appear on the lease.
Discuss and put in writing any agreements on splitting rent and bills.
Set clear terms for guests, chores, and notice periods among roommates.

Once your shared rental agreement is signed, you can find more about expectations and your rights in What Tenants Need to Know After Signing the Rental Agreement.

Security Deposit Rules

In Quebec, landlords cannot legally require a security deposit, key deposit, or last month’s rent in advance. Only the first month’s rent can be requested at signing.

For more, see Understanding Rental Deposits: What Tenants Need to Know.

Paying Rent as Roommates

Whoever is listed as a tenant is jointly and severally responsible for all rent. This means a landlord can collect full rent from any co-tenant, not just the one who missed a payment. Agree in writing on how you will split and pay rent each month.

Entering, Exiting, and Changing Roommates

Roommate changes are common in Quebec shared housing, but the steps to do so legally depend on your status:

If someone wants to move out but is listed on the lease, they must get landlord approval or legally transfer (assign) their portion of the lease.
Adding a new roommate typically requires landlord consent if the new person will be on the lease.
Informal or "occupant" roommates may have fewer protections if a dispute arises.

Official Forms: Lease Assignment and Subletting

In Quebec:

Assignment of Lease (Cession de bail) is used when a tenant transfers their entire lease to another person. Use the official form available for download on the Tribunal administratif du logement site (Cession de bail - Form 1).
Subletting (Sous-location) applies if a tenant wants to leave temporarily and allow a subtenant to use the apartment. Use the official subletting form (Sous-location - Form 2).

Example: If your roommate suddenly needs to leave, and you want to replace them, you would ask your landlord for permission to assign their place in the lease. The departing roommate completes the Cession de bail and gets landlord approval before the new roommate moves in.

Tip: Always maintain written communication with your landlord and other roommates when changing occupants, and keep copies of all forms and notices.

Dealing with Shared Housing Conflicts

Disagreements with roommates over noise, bills, or property damage are common in shared living. If issues aren’t resolved between yourselves, keep detailed records of incidents and discussions. For serious problems, you may contact the Tribunal administratif du logement (TAL) for guidance or to file a formal complaint.

Health, Safety, and Maintenance in Shared Rentals

Landlords are responsible for making sure the rental is safe, healthy, and in good repair, no matter how many tenants live there. If you spot hazards (like pests, mould, or broken locks), notify your landlord immediately in writing.
