Many tenants and renters in Ontario live with roommates, and understanding how a private roommate agreement differs from official lease rights can prevent disputes. A roommate agreement is a private contract between occupants that divides rent, utilities, chores and shared responsibilities, while a lease is a legal contract between tenants and a landlord that defines who holds tenancy rights under the Residential Tenancies Act, 2006. Knowing which document controls in disputes—especially over deposit returns, repairs or who can live in the unit—helps you protect your housing stability. This guide explains practical steps tenants can take to document agreements, what to expect from the Landlord and Tenant Board, and when to use official forms to assert rights.
How roommate agreements and leases differ
A roommate agreement is a private arrangement among occupants that clarifies who pays what and who is responsible for common tasks. A lease is the formal tenancy contract with the landlord and establishes legal tenancy rights. If a roommate is named on the lease, that person has direct rights against the landlord; if not, their protections mainly come from the signed lease-holder and any applicable roommate agreement.

Common roommate issues to address upfront
- Who pays rent and utilities each month and how to record contributions.
- Security deposit sharing and procedures for refunds when someone moves out.
- Proper notice procedures for leaving or changing occupants.
- Repairs, maintenance and reporting responsibilities for habitability issues.
- Record-keeping: receipts, photos, messages and other evidence to support claims.
- Moving out steps and returning keys to avoid deposit disputes.
When the lease controls — tenant rights under Ontario law
In Ontario, the lease and the Residential Tenancies Act, 2006 determine legal rights between tenants and landlords, not private roommate agreements. The Landlord and Tenant Board is the tribunal that resolves disputes about leases, rent, repairs and evictions[1]. For issues specifically about deposit handling, see Understanding Rental Deposits: What Tenants Need to Know. If your roommate arrangement conflicts with the lease—for example, an occupant is banned or the lease forbids subletting—the lease provisions and provincial law take priority[2].
Official forms and when to use them
The Landlord and Tenant Board provides official forms and instructions on filing applications and responses. Common form uses include filing applications to fix maintenance issues, asking the board to decide who owes rent, or applying for eviction remedies when needed. Example: if a roommate stops paying their share and the lease-holder cannot cover shortfalls, a tenant or landlord may use the board's application process to resolve arrears or ask for a payment order. See the LTB forms and guides for step-by-step form names and filing details[3].
FAQ
- Is a roommate agreement legally binding in Ontario?
- A roommate agreement between occupants can be a valid private contract, but it does not override the lease or the Residential Tenancies Act. If the agreement conflicts with the lease, the lease controls. For disputes that require a decision, the Landlord and Tenant Board handles matters involving tenancy rights.
- How should I split and recover a security deposit when a roommate moves out?
- Document the original deposit, keep receipts, and follow the lease terms. If the landlord holds the deposit, work with them to determine the correct refund; if a dispute remains between roommates about splitting, use written records and consider mediation or filing an application with the Landlord and Tenant Board.
- Can a landlord evict one roommate but keep another?
- A landlord can only remove a person who is a legal tenant under the lease or who does not have lawful occupation; eviction processes must follow the Residential Tenancies Act and typically require an order from the Landlord and Tenant Board.
How-To
- Gather clear records: collect rent receipts, bank transfers, photos and any written roommate agreement.
- Request mediation or communicate in writing to try to resolve the split or refund with your roommate and the lease-holder.
- Contact the landlord to confirm how the deposit is held and whether the lease covers partial refunds.
- If informal steps fail, prepare the appropriate LTB application or response and include copies of your evidence.
- File with the Landlord and Tenant Board and attend any scheduled hearing with the organized records and witness statements.
