Shared living arrangements have become increasingly common as housing costs continue to rise across Ontario. While sharing a rental unit can make housing more affordable, it also introduces a complex web of legal considerations that many tenants—and landlords—may not fully understand. What happens when your roommate moves out unexpectedly? Who's responsible for the full rent? Can a landlord evict you because of your roommate's actions?
The Legal Status of Roommates
One of the most misunderstood aspects of shared rentals is the legal status of roommates. The Residential Tenancies Act (RTA) does not prohibit roommates, but it also doesn't explicitly define their legal position.
In Hines-v-Rootes-20220125, the Landlord and Tenant Board (LTB) made this clear when dismissing a landlord's application to evict a tenant for allowing a roommate to move in: "The Landlord's own correspondence referred to the occupant as a 'roommate', and the Act does not prohibit roommates."
This distinction is important because:
- You can generally have roommates without landlord permission (unless your lease explicitly states otherwise)
- Landlords cannot automatically evict you for having roommates
- However, roommates who are not on the lease don't have the same legal protections as official tenants
Rent Responsibility When Roommates Leave
Perhaps the most common roommate dispute arises when one person moves out, leaving the remaining tenant(s) responsible for the entire rent. The LTB has consistently ruled that all tenants on a lease are jointly responsible for the full rent amount.
In Paramount-Properties-v-Alberu-20240903, the tenant argued he should only pay "his half" of the rent after his roommate moved out. The LTB rejected this argument, determining that "Tenant was informed and agreed to be solely responsible for full rent after roommate's removal from tenancy agreement."
Similarly, in AMI-v-KL-20160818, the Board found that "The Tenant cannot sustain this tenancy as he does not have the financial means to pay the full rent after his roommate moved out." Despite having several months to find a new roommate, the tenant was unable to do so and faced eviction for non-payment.
The lesson is clear: if you remain in a rental unit after your roommate leaves, you become responsible for the entire rent amount unless you have negotiated otherwise with your landlord.
Unauthorized Occupants vs. Roommates
Another common issue involves the distinction between legitimate roommates and unauthorized occupants. The line between these categories can be surprisingly thin.
In TI-v-JH-20180727, a tenant claimed "that the other occupants were simply roommates sharing the rental unit with the Tenant, and that there had been no unauthorized transfer of the tenancy." However, the LTB found that the tenant had effectively transferred occupancy to these individuals without permission, resulting in eviction.
The key factor often comes down to whether the original tenant continues to use the unit as their primary residence:
-
In SMC-v-PB-20160224, the tenant successfully argued that despite being frequently away for work, she maintained the unit as her primary residence and her roommate was legitimate.
-
Conversely, in Lem-v-Mclaughlin-20211222, the tenant vacated the unit but left it in possession of three roommates. While the landlord initially attempted to evict these roommates as unauthorized occupants, the fact that the landlord accepted rent from them was deemed to have approved the transfer of occupancy.
When Conflicts Turn Serious
Roommate conflicts can sometimes escalate beyond simple disagreements. In the extreme case of Ghebre-and-Mesfin-v-Brown-20220214, a tenant stabbed his roommate in the leg with a knife, resulting in police involvement and eventual eviction. The LTB found that this "seriously impaired the safety of other persons in the residential complex."
More commonly, conflicts involve issues like noise, food theft, or personal space violations:
-
In Zhang-v-Marziliano-20200922, "Conflict arose between Tenant and other tenants due to Tenant taking their food without permission," ultimately resulting in property damage when the tenant kicked and broke a door.
-
In SN-v-BB-20150615, the LTB noted that a tenant "had conflict with his roommate, which may have led to the rent arrears," highlighting how interpersonal issues can quickly evolve into financial problems.
Noise Complaints Between Neighbors
Noise complaints are among the most common disputes in multi-unit dwellings, whether between roommates or neighboring tenants. The LTB takes these issues seriously but requires substantial evidence.
In Medallion-Corporation-v-Balaos-20211103, the landlord failed to sufficiently investigate noise complaints against a tenant. The Board dismissed the eviction application, noting: "The Landlord did not sufficiently investigate the noise complaints and verify that the noises were coming from the Tenant's unit."
Similarly, in KB-v-LM-20160601, the tenant's application against the landlord for failing to address a neighbor's noise was dismissed because "the video evidence did not prove that the neighbor's music was loud enough to constitute substantial interference."
These cases demonstrate that while noise complaints are valid grounds for LTB applications, they require objective evidence and reasonable investigation.
Legal Options for Roommate Disputes
When roommate conflicts arise, what legal options exist?
-
For tenants on the lease:
- You can apply to the LTB if your roommate's behavior substantially interferes with your reasonable enjoyment
- You can negotiate with your landlord to remove a co-tenant from the lease (requires all parties' agreement)
- You remain jointly responsible for rent if other tenants leave or stop paying
-
For roommates not on the lease:
- Your protections under the RTA are limited
- Your relationship is primarily with the tenant who allowed you to move in, not the landlord
- If the primary tenant asks you to leave, you may have little recourse under tenancy law
-
For landlords:
- You can evict all tenants if unauthorized occupants move in without permission
- You can evict for substantial interference caused by any occupant of the unit
- You generally cannot evict simply because tenants have roommates
Preventative Measures
To avoid roommate disputes escalating to legal proceedings, consider these preventative steps:
-
Clear written agreements: All roommates should sign a roommate agreement detailing rent responsibilities, household rules, and what happens if someone needs to move out.
-
Proper tenant screening: In G.Q.-and-K.Q.-v-M.J.-20170628, the LTB noted that a "roommate who paid a share of the rent directly to the Landlords" was not considered a legal co-tenant because they weren't named on the lease. Ensure all long-term occupants are properly added to lease agreements.
-
Document everything: Keep records of all payments, communications about issues, and attempts to resolve conflicts. This evidence can be crucial if matters escalate to the LTB.
-
Open communication channels: Many disputes can be resolved through mediation or direct communication before they require legal intervention.
Conclusion
Navigating roommate relationships requires understanding both the legal framework and interpersonal dynamics at play. While the Residential Tenancies Act provides some guidance, many aspects of roommate relationships fall into gray areas.
The LTB cases examined show that tenants should be particularly cautious about rent responsibilities when roommates leave, the distinction between roommates and unauthorized occupants, and ensuring conflicts don't escalate to substantial interference.
For landlords, these cases highlight the importance of proper investigation before filing eviction applications, clear lease terms regarding occupants, and following proper procedures when addressing roommate-related issues.
Whether you're a tenant sharing space or a landlord managing a multi-occupant unit, understanding these legal nuances can help prevent costly disputes and maintain harmonious living arrangements.
