Top 5 Roommate & Shared Housing Rules for Ontario Tenants

Living with roommates in Ontario can be an affordable and social way to rent, but it also brings unique legal and practical challenges. Whether you're moving into a shared house, joining a group of tenants, or subletting a room, it's essential to understand your rights under Ontario tenancy law. This guide outlines the top 5 things tenants should know about roommates and shared housing, so you can avoid common pitfalls and maintain harmony in your living arrangements.

1. Know Who Is the Official Tenant

Not all roommates are treated equally under the law. In Ontario, only those who are named on the rental agreement (lease) with the landlord are considered official tenants. Others may be "occupants" or "subtenants," and their legal rights can differ.

• Tenant vs. Occupant: An "official tenant" is named on the lease and has rights under the Residential Tenancies Act, 2006^[1]. An "occupant" (for example, a friend invited to stay) is not directly protected.
• Subletting: If you rent your room to someone else while still being responsible to the landlord, that person is a "subtenant." You MUST follow the legal process and provide written notice to your landlord. Use Ontario’s Form N9: Tenant’s Notice to End the Tenancy (download official forms here) when leaving the unit permanently.
• If only one roommate’s name is on the lease, others may have no legal standing with the landlord – only with the main tenant.

Summary: Being on the lease gives you direct rights with the landlord. Otherwise, your rights depend on your arrangement with the tenant on the lease.

2. Roommate Agreements: Why They Matter

You may get along now, but relationships change. A written "roommate agreement" can help avoid disputes about chores, guests, bills, and damages. Although not legally binding under the Residential Tenancies Act, it is a valuable record if conflicts arise.

• List each person’s responsibilities: rent share, division of utilities, cleaning duties, and noise expectations.
• Outline how decisions are made and what happens if someone wants to move out early.
• Remember: The landlord is not bound by roommate agreements and may only enforce the official lease.

3. Paying Rent: Joint and Several Liability

When multiple tenants sign the lease together, you may be held "jointly and severally liable" for the full rent. This means if one roommate doesn't pay, the others can be required to cover the shortfall.

• Consider opening a joint account or using a rent-tracking app to ensure full payment each month.
• Keep receipts of your rent contributions.
• If a roommate leaves, inform the landlord right away. You might need to officially update the lease or find a replacement roommate, in line with the landlord's approval processes.

4. Health, Safety & Privacy

Every tenant in Ontario has the right to a safe and healthy home. Issues common in shared housing—like pests, cleanliness disputes, or security—can affect everyone in the house.

• Landlords must maintain the property, comply with safety codes, and respond to repair requests.
• You have the right to privacy in your own room, but you cannot deny the landlord access for valid reasons (with notice).
• If you encounter unresolved maintenance or health issues, you can involve the Landlord and Tenant Board, the official tribunal for Ontario tenancies, or local bylaw officers.

5. Leaving, Subletting, and Ending Agreements

Ending a shared tenancy is not always straightforward. Each named tenant must follow proper notice procedures—typically 60 days using Form N9: Tenant’s Notice to End the Tenancy (official forms), unless another arrangement is made.

• To sublet your room or assign your lease, landlord approval is usually required. Use Form N9 for ending your share, and consult the Residential Tenancies Act for assignment/subletting rules.
• Keep documentation of all communications with roommates and landlords.
• Remember, if your roommate leaves without notice, the remaining tenants can still be responsible for full rent.

It's safest to have all roommates sign the formal lease and notify your landlord of any changes right away.

Ontario Laws and Where to Get Help

All shared housing arrangements in Ontario are ultimately governed by the Residential Tenancies Act, 2006^[1]. Disputes are handled by the Landlord and Tenant Board (LTB). Download official forms, get dispute resolution information, and learn about your rights from the LTB website.

1. Am I responsible for my roommate's share of rent if they move out and I'm still on the lease?
   If you and your roommate are both named on the lease, most Ontario agreements make you "jointly and severally liable." This means the landlord can ask any remaining tenant(s) for the full amount due, even if you paid your share.
2. What happens if my roommate damages the apartment?
   In most cases, the landlord can recover costs from any (or all) tenants named on the lease. It's wise to document the condition of shared spaces and keep written agreements about responsibility for repairs.
3. How do I legally remove a problematic roommate?
   You cannot evict a roommate unless you are the tenant and they are a subtenant occupying your space (and not on the main lease). Otherwise, only a landlord can start eviction through the Landlord and Tenant Board.
4. What official form do I use to end my part of the lease?
   Use Ontario's Form N9: Tenant's Notice to End the Tenancy—found on the LTB website—to give legal notice to your landlord when you plan to leave.

1. How do I add a new roommate to the lease?
   Contact your landlord in writing to request adding the new roommate. The landlord may require a background check or application. Once approved, sign a revised lease including all parties.
2. How do I file a dispute against a roommate or landlord?
   If the dispute affects the tenancy or maintenance, submit an application to the Landlord and Tenant Board. Complaints about noise or damages between roommates are usually civil matters unless they're tied to the rental agreement.
3. How can I protect myself when moving into a new shared home?
   Request to be named on the lease, create a roommate agreement, and take photos of the unit's condition upon move-in. For more tips, review the Essential Tips for Tenants When Moving Into a New Rental Home.
