Living with roommates in Ontario offers an affordable way to enjoy rental housing, but it also raises important questions about splitting rent and deposits. Understanding your rights and responsibilities—and how Ontario law applies—can help prevent disputes and ensure a smoother shared living experience.
Key Rules for Rent and Deposit Sharing in Ontario
Ontario's Residential Tenancies Act, 2006 sets out rules for rental arrangements, including those with roommates. While sharing a unit can mean cost savings, every tenant should know how responsibilities are divided and enforced—both between roommates and with your landlord.
- Joint Tenancies: If all roommates sign the lease, each person is equally responsible for the full rent and complying with the agreement.
- Individual Tenancies: If roommates have separate agreements with the landlord, each is only responsible for their portion.
- Subletting/Assignment: If you're not on the lease, your relationship is often with your roommate(s), not the landlord.
How Is Rent Divided?
Unless your agreement clearly states otherwise, Ontario law holds joint tenants jointly and severally liable for the full rent. This means if one roommate doesn't pay, the others can be held responsible for the entire balance.
Roommates usually decide together how to split rent. Most common methods include:
- Equally (e.g., three people split rent three ways)
- By room size, amenities, or income
- Using a roommate agreement to put repayment terms in writing
Sharing Deposits: What Ontario Allows
Ontario landlords can only collect a deposit equivalent to one month's rent or one rental period—typically called the "last month's rent deposit." Security deposits for damages are not legal. When sharing with roommates, you’ll need to decide together how to split this deposit fairly. If everyone is on the lease, it’s common for each to pay their share. If someone leaves, replacement arrangements should be recorded.
For details on permitted deposits, see Understanding Rental Deposits: What Tenants Need to Know.
Important Forms and How to Use Them
Ontario tenants may need to use official forms if there’s a change in roommates or you need to end your arrangement. The Landlord and Tenant Board (LTB) is the official tribunal handling these matters: Landlord and Tenant Board (LTB) Ontario.
- Form N11: Agreement to End the Tenancy
- Official Form N11
- When to use: If all tenants agree to end the tenancy, use N11. For example, if you and your roommates are all moving out together, this form ends the lease with your landlord.
- Form N9: Tenant’s Notice to End the Tenancy
- Official Form N9
- When to use: If an individual tenant is ending their lease, use N9. It's important when one roommate wants to leave but others wish to stay.
- Form N12: Notice to End Your Tenancy Because the Landlord, a Purchaser or a Family Member Requires the Rental Unit
- Official Form N12
- When to use: If the landlord serves this form, all roommates need to respond accordingly.
Moving Out and Getting Deposits Back
If one roommate moves out, recovery of their share of the last month's deposit is typically between roommates—not the landlord. You should arrange for the departing roommate to be reimbursed by incoming tenants or by those staying behind.

Best Practices: Roommate Agreements
While not legally required, a roommate agreement written between co-tenants can help clarify:
- How rent, utilities, and deposits are split
- Rules for replacing roommates
- Shared responsibilities (cleaning, visitors, etc.)
If a single roommate fails to pay, the landlord can ask all joint tenants for the balance. It's smart to keep proof of payments to protect yourself.

Frequently Asked Questions
- What happens if one roommate doesn’t pay their share of the rent?
All tenants listed on the lease are legally responsible for the full rent. If one person doesn’t pay, the landlord may seek the remainder from the others. - Can a landlord keep the whole last month’s rent deposit if one roommate moves out?
No. The landlord holds the deposit for the unit, not for individual tenants. If a roommate leaves, it's up to the tenants to settle deposit repayments between themselves. - Is a roommate agreement legally binding in Ontario?
Roommate agreements are not governed under the Residential Tenancies Act but may be enforceable in civil court if you and your roommates sign one. - What if only one roommate wants to leave? Do we have to file a form?
An individual roommate can use Form N9 to end their own tenancy if they are on the lease. All roommates will remain unless the lease is formally updated. - Is there a typical way utilities are split among roommates?
Utilities are not regulated by the Act. Splitting is usually agreed upon among roommates, either equally or based on usage or room size.
Conclusion
- Roommate arrangements should always be clear and in writing for rent splits and deposit sharing.
- Last month’s rent deposits are held for the whole unit, not for individuals.
- Know which forms and agreements are needed for changing roommates or moving out to avoid disputes.
By understanding Ontario’s official rules, maintaining open communication, and keeping organized records, shared living can be positive and stress free.
