What Happens If Your Roommate Breaks the Lease in Northwest Territories?

Roommates & Shared Housing Northwest Territories 4 min read · published March 09, 2026 Flag of Northwest Territories

If you share a rental in Northwest Territories and your roommate suddenly decides to break the lease, it can leave you uncertain about your rights, responsibilities, and next steps. Understanding how tenancy laws apply in these situations is crucial for protecting your interests and avoiding preventable problems with your landlord.

Key Contacts: The NWT Rental Office and Applicable Legislation

In the Northwest Territories, residential tenancies are regulated by the Residential Tenancies Act (RTA). Disputes and applications are managed by the Residential Tenancy Office (RTO).

Your obligations and rights may depend on your specific rental agreement. Always check if both—or all—roommates signed the same lease (joint lease) or have individual agreements with the landlord.

Who Is Responsible When a Roommate Leaves?

Joint lease: If you and your roommate(s) signed the same rental agreement, you are usually considered "joint tenants." This means:

  • All tenants are equally responsible for rent and lease terms
  • If one person leaves before the end of the lease, the remaining tenant(s) must still pay the full rent

For individual leases, each roommate is responsible only for their own agreement. If in doubt, review your leasing documents or discuss with your landlord.

What Happens to the Security Deposit?

The fate of your security or damage deposit will depend on how it was paid and whose names are listed as tenants. Joint tenants typically have a shared deposit, so if one leaves, the deposit usually remains with the tenancy until everyone moves out or the lease ends. For details on tenant deposit rights, see Understanding Rental Deposits: What Tenants Need to Know.

Steps to Take When Your Roommate Breaks the Lease

  • Communicate promptly with your landlord if you know your roommate is leaving or has left
  • Check your lease for "joint and several liability" clauses or requirements for replacing tenants
  • Work out an agreement if you want to bring in a new roommate (this may require your landlord's approval in writing)
  • Consider contacting the Residential Tenancy Office for guidance or to resolve disputes

If you cannot afford the rent alone, discuss your options with your landlord. They may permit a sublet or new lease application, but you must follow legal procedures outlined in the RTA.

Official Forms and How to Use Them

  • Notice to Terminate Tenancy (Form RT01-B): Use this form if you and your remaining roommates want to end the tenancy. Each tenant wishing to leave must sign. Download Notice to Terminate Tenancy (RT01-B)
  • Application to RTO (Form RT03): Use this if you need a formal decision—for example, if the landlord does not agree to replace a roommate or there is a dispute. Download Application to RTO (RT03)

Practical example: If your departed roommate refuses to pay their share after leaving, you could apply to the RTO for a rent-recovery order.

Ending the Lease Early: What Are Your Rights?

Whether you can end the lease or stay depends on your agreement and communication with the landlord. If you want to leave early, consult the guidelines in What to Do If You Need to Leave Your Rental Before the Lease Expires.

Tip: Always give written notice and keep copies for your records. Following official forms and timelines is critical to avoid losing your deposit or affecting your rental history.
Keep dated written notice and copies for your records; failing to follow timelines can affect your deposit or lease history. Check your lease and RTA timelines for notice requirements to avoid penalties.

Financial and Practical Impact

  • You may have to pay the full rent if your roommate’s share is not covered
  • You could be held responsible for any property damage, missed rent, or cleaning caused by your roommate unless the landlord agrees otherwise
  • Finding a new roommate quickly can help maintain your financial stability, but the landlord must approve any new occupant in writing

Remember, you can find rental homes across Canada on Houseme if you decide to move out and start fresh elsewhere.

FAQ: Roommate Lease Breaks in Northwest Territories

  1. What if my roommate didn’t give notice and just left?
    Under a joint lease, you remain responsible for the full rent unless your landlord releases you from the agreement or finds a replacement tenant.
  2. Can I bring in a new roommate if one leaves?
    Generally yes, but you need written consent from your landlord. Get any new roommate added to the written lease or complete a new tenancy agreement.
  3. Will my security deposit be refunded?
    Deposits are normally only returned at the end of the tenancy, and any damages or unpaid rent may be deducted. You may need to negotiate dividing the deposit if only one roommate leaves.
  4. What are my options if I can’t pay the full rent?
    Discuss payment solutions with your landlord right away. You may apply to the Residential Tenancy Office for help or to end the lease legally.

Conclusion: What Tenants Should Know

  • If your roommate leaves, you may be responsible for their share of rent and damages under a joint lease
  • Use official forms and follow NWT procedures to protect your rights and deposits
  • The Residential Tenancy Office can help with disputes or questions about your legal obligations as a tenant

Staying informed and proactive makes shared housing transitions smoother in the Northwest Territories.
