How to break a lease early in Ontario: assignments, N11s, and your rights

New job in another city. A relationship that ended. A landlord who won’t fix the heat. Whatever the reason, you need out of your Ontario lease before it ends — and the lease says you owe rent for the rest of the term. Most tenants assume the only escape is to pay out the remainder, or to lose their deposit. Ontario law is more generous than that.

The Residential Tenancies Act, 2006 (the “RTA”) gives tenants four legal paths to end a fixed-term lease early, and a fifth that just runs out the clock. Most landlords don’t advertise these. This guide is the plain-English version, referenced to the actual sections of the RTA so you can quote them if you have to.

Myth #1: “I’m locked in for the full term”

A 1-year lease in Ontario isn’t a 12-month financial commitment. At the end of the term the tenancy automatically becomes month-to-month under RTA s.38 — the tenant doesn’t have to renew, and the landlord can’t demand another fixed-term. So “breaking a lease” really only matters during the fixed-term window. Outside of it, all you need is a 60-day N9 notice.

Myth #2: “The lease has a $2,000 break fee”

Doesn’t matter what the lease says. Under RTA s.3, any clause in the lease that conflicts with the Act is void. The Act doesn’t allow break-the-lease penalties, liquidated-damages clauses, or fees for early termination — so those clauses can’t be enforced at the LTB. The only money a landlord can recover from an early-departing tenant is the actual rent lost until they re-rent the unit (more on that below).

Path 1: N11 — Agreement to End the Tenancy (the easiest)

Authorised by RTA s.77. The landlord and tenant both sign Form N11 agreeing on a termination date. Once signed, the tenancy ends on that date and neither party owes anything further (other than the tenant being out and the landlord returning the last month’s rent deposit if it wasn’t applied to the final month under s.106).

• Both parties have to sign voluntarily
• Any date works — even tomorrow, if both sides agree
• Once signed, it’s binding — neither side can back out
• Form N11 is on Tribunals Ontario’s site, not LTB-filed

This is almost always the first move. Email or text your landlord: “I need to leave the unit on [date]. Will you sign an N11?” A reasonable landlord — one who’d rather find a new tenant than chase a fight — will usually say yes, especially if you offer 30 days’ notice and to help show the unit.

Never sign an N11 the landlord drafts before you’ve read it. Some landlords slip in clauses about “forfeiting the deposit” or “owing $X.” You don’t have to agree to those — and the LTB will ignore them even if you sign.

Path 2: Assignment under RTA s.95

An assignment transfers the entire tenancy to a new tenant. The new person takes over the existing lease at the existing rent, on the same terms. You’re fully out — no more rent obligations, no more responsibility.

How it works:

1. You ask the landlord, in writing, for consent to assign. Naming a specific assignee is allowed but optional.
2. The landlord has three legal options under s.95:
   • Consent to the assignment (with or without naming the assignee)
   • Refuse the proposed assignee on reasonable grounds (e.g. credit check failed, income too low)
   • Refuse to even consider any assignment — at which point you get an escape hatch
3. If the landlord refuses to consider the request or doesn’t respond within 7 days, RTA s.95(4) lets you give written notice to terminate within 30 days after the request, ending the tenancy 30 days later. You walk away cleanly even though the landlord never agreed.
4. If the landlord agrees in principle but refuses a specific assignee, you can challenge that refusal at the LTB on Form T9 — or just propose another assignee.

The landlord can charge reasonable expenses (RTA s.95(8)) — typically advertising costs and a credit check for the assignee, capped at what the landlord actually spent. They can’t charge a flat “assignment fee.”

Path 3: Sublet under RTA s.97

A sublet is different from an assignment: you stay on the lease, find a subtenant to occupy the unit for a defined period (less than the rest of the lease), and move back in before the lease ends. It’s the right tool for someone leaving the country for 6 months, not someone who needs to leave permanently.

• You remain legally responsible to the landlord for rent and damage
• The subtenant pays you (you pay the landlord)
• You must come back before the sublet ends — otherwise the subtenant becomes an “unauthorised occupant” that the landlord can evict
• Same landlord-consent rules as assignment — can’t be unreasonably refused

If permanent departure is what you actually need, an assignment is the right path, not a sublet.

Path 4: N9 at the end of the fixed term

If the end of your fixed-term lease is only a couple months away, the simplest path is often to wait it out. Under RTA s.44:

• For a fixed-term tenancy, you can serve Form N9 to end the tenancy on the last day of the term, with at least 60 days’ written notice.
• For a month-to-month tenancy (after the fixed term has auto-rolled), you can serve N9 to end on any rental-period end date with 60 days’ notice.

N9 is unilateral — you don’t need the landlord’s permission. You just have to count the days correctly and put a valid termination date on the form.

Path 5: Special termination rights (mid-term)

A handful of circumstances let a tenant end a fixed-term tenancy early without needing the landlord’s consent and without going through assignment:

• Domestic violence or sexual violence (RTA s.47.1–47.3). 28-day written notice on Form N15. The tenant must attach either a sworn declaration in the prescribed form or a copy of a restraining order / court order. The landlord cannot challenge the validity of the notice. Other co-tenants on the lease are not released by this notice.
• Move-in to long-term care or retirement home (RTA s.48.1). 60-day notice in some circumstances; the rules vary based on the tenant’s age and care needs.
• Landlord’s serious breach — illegal entry, harassment, failure to do major repairs that make the unit uninhabitable. You can apply to the LTB on Form T2 or T6 to terminate the tenancy and recover damages. This is slow (6–12 months) and you have to keep paying rent while the application is pending.

What if I just leave without doing any of this?

You’re on the hook for rent — but not for the rest of the lease automatically. Under RTA s.16, the landlord has a duty to mitigate: they have to take reasonable steps to re-rent the unit. They can’t just leave it empty for 8 months and bill you.

In practice, that means:

• The landlord must advertise the unit at a reasonable rent
• The landlord must show the unit to prospective tenants
• If they re-rent on June 1 and you left on April 15, you owe rent only for April 16 through May 31 (plus any direct costs they reasonably incurred to re-rent)
• If the landlord doesn’t try at all and just sues you for the full term, the LTB or court will reduce the award sharply

Still: just leaving is the worst option. It puts you in a fight you can lose, damages your rental references, and may result in a money order showing up in your credit history. An N11 or assignment is almost always cleaner.

What landlords can and can’t do

• Can reasonably refuse an assignee whose credit / income / references genuinely don’t support paying the rent.
• Can charge documented expenses for processing an assignment (advertising, credit check) — not a flat fee.
• Cannot enforce a “break fee” clause from the lease.
• Cannot refuse to consider an assignment request — refusal to consider triggers the s.95(4) escape hatch.
• Cannot keep the last month’s rent deposit as a penalty. LMR can only be applied to the actual last month of the tenancy (RTA s.106).
• Cannot retaliate (rent increase, lease non-renewal harassment) because a tenant asked to leave or assign. Retaliation can be challenged on Form T2.

Step-by-step: the decision tree

1. Is the fixed term about to end (within ~3 months)? Serve a 60-day N9. Done.
2. Can you talk to the landlord? Ask for an N11. Sign one with a date that works for both of you. Done.
3. Landlord won’t agree to an N11? Send a written request to assign the tenancy under s.95. Wait 7 days.
4. Landlord ignored you or refused to consider? Send written notice terminating the tenancy 30 days later under s.95(4). Move out. Done.
5. Landlord agreed in principle but rejected your specific assignee? Propose another assignee, or file Form T9 at the LTB to challenge the refusal.
6. Mid-term, special circumstance? N15 (violence), s.48.1 (long-term care), or T2/T6 (landlord breach).

For landlords: what to do when a tenant asks to leave

If you’re the landlord and your tenant tells you they need out, the strategic question is: can you re-rent for at least the same amount? If yes, sign the N11. You collect the same rent from a new tenant, the leaving tenant exits cleanly, no LTB fight.

If the answer is “no, the market has dropped” — you still have options. You can:

• Negotiate: tenant pays you 1–2 months of the gap in exchange for the N11
• Allow assignment instead, letting the tenant find a replacement at the existing (higher) rent
• Refuse the N11 and refuse the assignment, but understand the tenant may invoke s.95(4) and leave anyway — at which point your duty to mitigate kicks in

Refusing everything and demanding the full remaining rent is rarely a winning move. The LTB will reduce the claim by what you should have collected if you’d re-rented, and the tenant may simply move out anyway.
