Free Ontario Sublease Agreement Form | PDF & Word Template
Ontario Sublease Agreement is a legal document used when a tenant rents out their unit to another person for a temporary period. If you’re planning to sublease in Ontario, this article gives you a free template + clear legal rules + step-by-step help.
A sublease agreement is when a tenant (not the landlord) rents their place to someone else for a short time.
Simple example:
You rent an apartment in Toronto but leave for 3 months. Instead of paying empty rent, you allow someone else to stay there and pay rent during that time. That’s a sublease.
I’ve seen a lot of Ontario tenants get into trouble because they assumed a simple text message or verbal permission was enough for a sublease. In Ontario, missing landlord consent or using unclear terms can quickly turn into disputes over rent, damage, or even eviction applications.

| Federal involvement | Residential tenancy law is provincial jurisdiction only and not governed by a federal statute. | Residential Tenancies Act, 2006, S.O. 2006, c. 17 |
| Who can legally sign | The tenant acting as sublandlord and the subtenant can sign the agreement, but landlord consent is required. | Residential Tenancies Act, 2006, s. 97(1) |
| Witness requirements | Ontario law does not require witnesses for a residential sublease agreement. | N/A |
| Notarization | Ontario law does not require notarization for a residential sublease agreement. | N/A |

A.7; Minors’ Contracts Signatures Act, R.S.O. 1990, c. M.18 |
| Sublease time limit | The sublease term must explicitly expire at least one day prior to the end of the tenant’s fixed-term lease. If the tenancy is month-to-month (periodic), the sublease cannot extend past the end of the specified rental period without legally transforming into an assignment. | Residential Tenancies Act, 2006, S.O. 2006, c. 17, s. 2(1) “sublet |
| Mandatory government form | Ontario does not currently require a government-issued standard sublease form. | Residential Tenancies Act, 2006, s. 12.1 |
| Landlord consent clause | A valid sublease must include or be subject to landlord consent. | Residential Tenancies Act, 2006, s. 97(1) |
| Charging higher rent | A tenant cannot legally charge a subtenant more rent than they pay the landlord. | Residential Tenancies Act, 2006, s. 98(4) |
| Filing or registration | Ontario sublease agreements do not need to be filed with ServiceOntario or the Landlord and Tenant Board. | N/A |
| Invalid sublease risk | A sublease without landlord consent may be treated as an unauthorized occupancy. | Residential Tenancies Act, 2006, s. 97(1) |
| Assignment vs sublease issue | If the sublease continues on or after the tenant’s lease end date, it may legally become an assignment instead. | Residential Tenancies Act, 2006, s. 2(1) |
| Unreasonable refusal by landlord | A landlord cannot arbitrarily or unreasonably refuse a sublease request. | Residential Tenancies Act, 2006, s. 97(2) |
One of the biggest surprises for many Ontario tenants is that a landlord cannot simply reject a sublease request without a valid reason. Under Ontario law, unreasonable refusal can create legal options for the tenant through the Landlord and Tenant Board.
Another important rule is the strict ban on charging higher rent to a subtenant. Many people assume they can make extra money while away temporarily, but Ontario specifically prohibits this. These rules matter in real life because small mistakes can create major problems. Subleasing without written landlord approval could leave the subtenant without legal protection and may even put the original tenant at risk of eviction.
Likewise, if the sublease runs too long, the arrangement could legally become an assignment instead of a sublease, changing everyone’s rights and responsibilities. Understanding these Ontario-specific rules before signing anything can save tenants from disputes, financial loss, and lease complications later.

What Is a Sublease Agreement in Ontario?
Under Ontario law, a sublease is a temporary rental arrangement where:
- The original tenant stays on the lease
- A new person (subtenant) lives in the unit
- The landlord still deals legally with the original tenant
Real-life example
A university student in Ottawa leaves for summer break. Instead of ending the lease, they sublease their room for 4 months.
Key people involved:
- Original Tenant (Sublandlord) → You
- Subtenant → The person moving in
- Landlord → Property owner (must approve)
A sublease agreement in Ontario must follow the conditions outlined in the primary lease contract. Tenants should also review their legal rights and ensure compliance with Ontario subletting laws. For shared living, a roommate agreement may be required, and for temporary arrangements, a month-to-month lease is useful.
Sublease vs Assignment
This is where many tenants get confused.
What is a Sublease?
- Temporary
- You return after it ends
- You stay legally responsible
What is an Assignment?
- Permanent transfer
- New tenant replaces you
- You are no longer responsible

If you’re leaving forever → assignment
Is Subleasing Legal in Ontario?
Yes — subleasing is legal under Ontario law, but with conditions.
Under the Residential Tenancies Act, tenants:
- Must get landlord’s permission
- Landlord cannot unreasonably refuse
Important rule:
Landlords are not allowed to reject a sublease without a valid reason.
If the landlord arbitrarily, unreasonably, or capriciously refuses consent to a specific subtenant request:
- You may file a Form A2 (Application about a Sublet or an Assignment) with the Landlord and Tenant Board (LTB) to seek an order authorizing the sublet, or terminating the head tenancy under Section 97(3) of the RTA.
- Alternatively, you may give the landlord a 30-day Form N9 (Tenant’s Notice to End the Tenancy) if they issue a blanket, general refusal to allow subletting or assignment under Section 95(4) of the RTA.
Always get approval in writing to stay protected.
When Should You Use a Sublease Agreement?
Subleasing is useful in many real situations:
Common scenarios:
- Temporary job in another city
- Traveling for a few months
- Students leaving during summer break
- Moving in with a partner temporarily
Example:
You move to Vancouver for a 3-month internship. Instead of paying double rent, you sublease your Ontario apartment.
Key Elements of a Valid Ontario Sublease Agreement
A good agreement should clearly cover these points:
Tenant and Subtenant Details
Include full names and addresses.
Rental Property Description
Write exact unit address and type (room, condo, basement, etc.).

Rent Amount and Payment Terms

- Due date
- Payment method
Under Ontario law, you cannot charge more rent than your lease.
Landlord Consent Clause
Mention that landlord approval is given.
Rules from Original Lease
The subtenant must strictly adhere to all lawful covenants of the primary lease. However, take note of statutory carve-outs:
- Pet Restrictions: Under Section 14 of the RTA, “no pet” clauses are completely void. You cannot prohibit a subtenant from having a pet unless the property is governed by strict Condominium Act bylaws that explicitly bar animals.
- Noise and Conduct: The subtenant must comply with Section 64 of the RTA regarding substantial interference with reasonable enjoyment.
- Maintenance: While you can require the subtenant to keep the unit clean, your primary statutory obligation under Section 20 to maintain the complex in a good state of repair cannot be offloaded to the subtenant via contract.
Utilities and Responsibilities
Clearly mention:
- Who pays electricity, internet, water

You still owe rent to landlord.
Landlord takes action
They will contact you — not the subtenant.
Key rule:
The original tenant is always responsible.

FAQs
Do I need landlord permission to sublease?
Yes. It is required under Ontario law.
Can I make profit from subleasing?
No. You cannot charge more than your rent.
Who pays rent to the landlord?
You (original tenant) remain responsible.
Can a subtenant be evicted?
Yes, but usually through action against the original tenant.
Is a verbal sublease valid?
While oral tenancy contracts can exist under the general definitions of the RTA, an oral sublease is an operational disaster. Because Section 97(1) mandates the explicit consent of the landlord, any failure to secure written, verifiable landlord consent allows the landlord to treat the incoming occupant as an unauthorized over holder. The landlord can then file a Form A4 application to evict both you and the occupant within 60 days of discovering the arrangement under Section 100.
