Ontario's Residential Tenancies Act does not impose an automatic penalty for breaking a fixed-term lease early. However, a tenant who leaves without an agreement or proper notice may remain responsible for rent until the unit is re-rented or the lease's natural end date, whichever comes first — because the landlord has a legal duty to mitigate losses by making reasonable efforts to re-rent promptly.
- There is no automatic "lease-break fee" a landlord can simply charge under the Residential Tenancies Act.
- A tenant who leaves early without agreement may remain responsible for rent until the unit is re-rented or the lease term ends, whichever is sooner.
- Landlords have a legal duty to mitigate — they must make reasonable efforts to re-rent the unit, not simply let it sit vacant and bill the departing tenant.
- The cleanest way to end a fixed-term lease early is a mutual agreement (N11) with the landlord.
- Assigning the lease to a new tenant (with landlord consent) can avoid future rent liability entirely.
- A tenant escaping an unsafe situation may have additional options under the Residential Tenancies Act's specific early-termination provisions.
No Automatic Penalty for Breaking a Lease Early
Under Ontario's Residential Tenancies Act, 2006, there is no automatic "lease-break fee" that a landlord can simply charge a tenant for ending a fixed-term lease before its natural end date. Many tenants assume otherwise — and many landlords wrongly try to demand one. The reality is more nuanced: if a tenant leaves without an agreement or proper notice, they may remain financially responsible for rent until the unit is re-rented or the lease term ends, whichever comes first.
The Landlord's Duty to Mitigate
A landlord cannot simply let a unit sit vacant and bill the departing tenant for the full remaining term. Ontario law imposes a duty to mitigate — the landlord must make reasonable efforts to re-rent the unit as soon as possible, such as advertising it promptly and showing it to prospective tenants. If a landlord fails to make reasonable efforts, a tenant can challenge some or all of the rent loss claimed against them.
Prompt advertising, reasonable rent pricing (not inflated above market to discourage re-renting), and cooperating with showings are generally expected. A landlord who drags their feet weakens their claim for lost rent.
Your Three Real Options
- Mutual agreement to end the tenancy (N11). The cleanest path — you and your landlord agree in writing on a specific move-out date, and once signed, you generally owe nothing further.
- Assign the lease to a new, qualified tenant with your landlord's consent, releasing you from further liability once the assignment is complete.
- Give proper notice and leave, understanding you may remain liable for rent until the unit is re-rented or the term naturally ends, subject to the landlord's duty to mitigate.
Get any agreement to end your tenancy early in writing, ideally on the official N11 form. A verbal understanding with a landlord who later changes their mind is difficult to prove and enforce.
Assignment vs. Subletting — A Critical Difference
These terms are often confused, but the legal consequences are very different:
| Option | Who's Responsible Afterward |
|---|---|
| Assignment | The new tenant takes over the lease permanently; you are released |
| Subletting | You remain the tenant of record and stay legally responsible |
If your goal is to fully exit your obligations, an assignment — not a sublet — is what accomplishes that. See our full guide on subletting and assigning your rental for the consent rules and process.
Special Circumstances
The Residential Tenancies Act provides specific early-termination protections in certain circumstances, including situations involving personal safety. These provisions have their own documentation requirements and are distinct from an ordinary early departure — if this may apply to you, get legal advice before assuming the general rules above are your only option.
If You're the Landlord
If a tenant leaves early, document the date they vacated, advertise the unit promptly at a reasonable market rent, and keep records of your re-renting efforts — this protects your ability to claim any genuine rent loss. Pursuing a departed tenant for unpaid rent after re-renting is typically done through Small Claims Court rather than the LTB, since the tenancy itself has already ended.
A tenant with 8 months left on a one-year lease gives notice and moves out for a new job in another city, without a signed agreement to end the tenancy. The landlord re-advertises immediately and finds a new tenant within 3 weeks. The departing tenant is responsible for those 3 weeks of lost rent — not the remaining 8 months — because of the landlord's duty to mitigate.
How to Minimize What You Owe
- Give as much notice as possible, even beyond what is strictly required, to give the landlord a real head start on re-renting.
- Offer to help find a replacement tenant, whether through an assignment or by referring qualified candidates.
- Get everything in writing — any agreement, any timeline, any amount discussed.
- Keep your own records of when you left and any communication about re-renting efforts, in case a dispute arises later.

Frequently Asked Questions
Not automatically. There is no statutory "lease-break fee" under the Residential Tenancies Act. If you leave without an agreement or proper notice, you may be responsible for actual rent lost until the unit is re-rented — but the landlord must first try to re-rent it, not simply charge you the full remaining term.
It means the landlord must make reasonable efforts to re-rent the unit as soon as possible once they know you have left, rather than leaving it vacant and holding you liable for the full remaining term. If they fail to make reasonable efforts, you may be able to challenge some or all of the claimed rent loss.
A mutual agreement with your landlord, using form N11, is the cleanest option — you and the landlord agree on a specific move-out date, and once signed, you generally owe nothing further for the remainder of the term.
Yes, with your landlord's consent, you can assign your lease to a new tenant. Once a proper assignment is completed, your ongoing obligations under the lease generally end, and the new tenant steps into your place.
With an assignment, a new tenant takes over the lease permanently and you are released from further liability. With a sublet, you remain the tenant of record and remain legally responsible for the unit even though someone else is living there and paying you.
Generally no, beyond the period the unit was actually vacant. Because of the landlord's duty to mitigate, once a new tenant is paying rent, your liability for that period typically ends.
The Residential Tenancies Act provides specific early-termination protections in certain safety-related circumstances. If this applies to you, get legal advice promptly, as the process and required documentation differ from an ordinary early departure.
