What Happens When a Roommate Breaks Lease in PEI?

Roommates & Shared Housing Prince Edward Island 5 min read · published March 09, 2026 Flag of Prince Edward Island

If your roommate unexpectedly moves out or breaks the lease in Prince Edward Island (PEI), you may feel anxious about your own rights, responsibilities, and what steps to take next. Understanding how shared leases work and what the PEI laws say can help you make confident decisions during this stressful time.

Roommates & Shared Housing in PEI: The Basics

In PEI, rental housing arrangements with roommates usually fall under one of two types:

  • Co-tenancy: All roommates are on the lease and share equal responsibility for rent and damages.
  • Subtenancy or Boarder Arrangements: Only one tenant is on the lease (the primary tenant), and the others are subtenants or boarders without a direct agreement with the landlord.

If your name appears on the lease with your roommate, you are jointly and severally liable. This means you’re each responsible for the full rent—if one person leaves, the remaining tenant(s) can be held responsible for the entire balance.

What Happens When a Roommate Moves Out Early?

When a roommate ends their part of the lease early (with or without notice), several outcomes are possible:

  • You may be responsible for the full rent if your name is on the lease.
  • You may need to find a replacement roommate or negotiate a new agreement.
  • The landlord is not required to change the lease or reduce the rent just because one roommate left.

In cases where only one tenant signed the lease, and your name isn’t on it, the legal responsibilities will look different—mainly, the named tenant remains responsible to the landlord.

If you aren’t on the lease, your liability is limited to what the landlord requires of the named tenant, but you should still document communications and understand whether you’ll be added to the lease or need a separate agreement.

Official Oversight and Legislation

All landlord-tenant matters in PEI are managed by the Director of Residential Rental Property, Department of Justice and Public Safety. The main law is the Rental of Residential Property Act (PEI)[1].

PEI tenancy matters are governed by provincial legislation, so key steps (like notice periods and forms) follow specific rules in the Rental of Residential Property Act.

Key Steps if Your Roommate Breaks the Lease

  • Check your lease agreement for terms about breaking the lease or who is legally responsible.
  • Communicate with your landlord as soon as possible.
  • Decide whether you want to remain or end the tenancy (you may have options).
  • Consider finding a new roommate to help share the rent.
  • If you wish to end your tenancy entirely, follow proper notice rules (see below).
Deposits shared between roommates can become a dispute. Get everything in writing with the landlord and your former roommate about who gets what at the end of the tenancy.

If the departing roommate is also listed on deposits, damages, or shares utilities, consult your landlord and document all communications.

Important PEI Forms When Handling Roommate Departures

  • Form 4 - Notice of Termination by Tenant:
    Use this form if you wish to end your own tenancy. It must be given to the landlord with proper notice (usually one month for month-to-month leases).
    Download PEI Form 4.
    Example: If covering both your share and your roommate’s share isn’t possible, you might decide to give notice and move out lawfully.
  • Form 2 - Application by Landlord or Tenant:
    Used if disputes arise (e.g., over deposits, property damages, or rent owed).
    Get PEI Form 2.
    Example: If you’re left solely responsible for damages you didn’t cause, you may use this form to seek a hearing.
Keep a file with all Form 4 and Form 2 submissions, receipts, and landlord communications. These documents are essential if you need to prove notice periods or resolve disputes.

Always keep a copy of all submitted forms and written records with your landlord and former roommate.

Who Recovers the Rental Deposit?

Rental deposits can be tricky when roommates split. If you and your roommate both paid a deposit, it’s usually returned at the end of the lease to all named tenants on the agreement. The landlord is not obliged to “return” half a deposit if just one tenant leaves; any split is your responsibility to resolve between roommates. For more information, see Understanding Rental Deposits: What Tenants Need to Know.

If deposits were paid jointly, agree in writing on how it will be returned at tenancy end; coordinate with your former roommate to avoid disputes.

Ending or Changing a Lease after a Roommate Leaves

If you want to end your own tenancy after your roommate leaves, serve notice according to your lease and PEI law (typically in writing, using Form 4). To stay and add a new roommate, discuss with your landlord if they require screening or a new lease altogether. Always get any new agreement in writing.

Financial Responsibility and Rent

If you stay, you are still responsible for the full rent. The landlord may pursue any named tenant(s) for unpaid rent or damages. For ongoing payments, review Tenant's Guide to Paying Rent: Rights, Responsibilities, and Tips.

Tip: If your roommate left with little warning or without paying their share, document all communications. If the total rent isn’t paid, landlords can issue a Notice of Termination.
