Roommate relationships in Ontario rentals can get complicated—especially if your roommate fails to pay their share of the rent. Understanding your responsibilities is crucial to avoid unwanted consequences like eviction or negative credit impacts. This guide will clarify what Ontario law says about rent responsibilities in shared housing, including your options if you’re stuck with a non-paying roommate.

Roommates and Rent: How Does Ontario Law Treat Shared Housing?

In Ontario, your legal responsibilities for rent depend on the type of rental agreement you and your roommate have with the landlord. The two most common scenarios are:

• Joint Tenancy: All tenants (including roommates) sign the same lease and are equally responsible for rent.
• Individual Tenancy: Each roommate signs a separate agreement with the landlord and is only responsible for their share.

If your name appears on the lease with your roommate, you are considered a joint tenant. This means the landlord can hold any or all tenants responsible for missed rent, regardless of who didn’t pay their share¹. If you have separate agreements, you’re only responsible for your own rent share.

What Happens When Your Roommate Doesn’t Pay Their Share?

With joint tenancy, the landlord may ask you to cover your roommate’s unpaid portion—even if it’s not your fault. If nobody pays, the landlord can file for eviction or for the unpaid rent through the Landlord and Tenant Board of Ontario (LTB).

In practice:

• Your credit or rental history may be affected if the total rent isn’t paid and the landlord takes legal action.
• The landlord can choose to pursue any or all joint tenants for the full amount owed.
• Issues between roommates (e.g., collecting your roommate’s share) are considered private disputes and not handled by the LTB.

Protecting Yourself: Tips and Tenant Responsibilities

Whether you signed together or separately, it’s important to know your obligations. Here are practical steps tenants can take:

• Before moving in, clarify the rental agreement type with your landlord.
• Keep copies of the lease and any written agreements with your roommate.
• Pay your portion of the rent directly to the landlord and get receipts or proof of payment.
• If only your roommate’s name is on the lease, speak with the landlord to clarify your arrangement.

A written roommate agreement can’t overrule your legal lease with the landlord, but it can help resolve disputes if your roommate misses payments.

What to Do If Your Roommate Doesn’t Pay Rent

If your roommate isn’t paying their rent, take these steps to protect yourself:

• Talk to your roommate to try to resolve the issue early.
• Notify your landlord as soon as you’re aware there may be a missed rent payment.
• Continue paying your share directly. If you can, pay the total amount to avoid negative consequences, then seek reimbursement from your roommate.
• Document your communications and all payments made.
• If you want to move out as a result, follow the proper procedures to end your tenancy.

1. What if my roommate is on the lease, but I’m not?
   If only your roommate signed the lease, you are not legally responsible to the landlord for missed rent. However, you may be required to move out if your roommate is evicted or ends their tenancy.
2. Can the landlord evict me because my roommate didn’t pay?
   If both names are on the lease, the landlord can seek eviction of all tenants—even if you paid your share. If only your roommate is on the lease, your status may be as an occupant rather than a tenant.
3. Can I sue my roommate for unpaid rent?
   Yes, you can consider small claims court if you paid extra due to your roommate’s failure to pay. The Landlord and Tenant Board does not resolve disputes between roommates.
4. Do I need to file any forms if I want to move out?
   You may need to provide proper written notice or use Form N9 (Tenant's Notice to End the Tenancy) if you are a tenant on the lease. Always check the required notice periods.
5. Who can I contact for help or legal advice?
   You can reach out to local tenant advocacy organizations or the Landlord and Tenant Board in Ontario for information about your rights and responsibilities.

Key Takeaways

• You may be responsible for your roommate’s unpaid rent if you both signed the same lease.
• Always pay your share directly and keep records to protect yourself.
• Talk to your landlord and seek support early if you face issues.

Understanding your lease and Ontario’s tenancy laws is the best way to protect your home and financial stability as a tenant.
