How to Break a Lease in Ontario: What the Law Allows

Breaking a lease in Ontario is possible, but only through specific routes the Residential Tenancies Act actually recognizes, not by simply giving your landlord a heads-up and moving out. If a job relocation, a relationship change, or an unsafe living situation has you looking for a way out before your term ends, the law gives you real options: ending things by mutual agreement, handing the unit off through an assignment or a sublet, or, in specific documented circumstances, shortened notice for hardship. What it doesn’t give you is a free pass to walk away from rent you still owe, and knowing the difference matters before you make a move. This guide covers what’s actually legal, what it costs you if you skip the process, and where to go if a landlord won’t cooperate, alongside everything else covered in our complete Toronto real estate guide.

What actually happens when your fixed term ends

A one-year lease in Ontario doesn’t expire the way most people assume it does. Once a fixed term ends, the tenancy automatically continues as a month-to-month tenancy on the same terms and conditions, under the Residential Tenancies Act. You’re not obligated to sign a new fixed-term lease if your landlord offers one, and your landlord can’t end your tenancy simply because the original term is over. Expiry of a fixed term is not, on its own, a legal ground for eviction.

That matters for anyone trying to break a lease, because it changes what “ending” the lease actually means depending on timing. If your fixed term has already lapsed and you’re now on a month-to-month tenancy, you’re working with the standard notice rules for a periodic tenancy. If you’re still inside an active fixed term and want out before it lapses, you need one of the specific routes below, since standard notice alone doesn’t end a fixed term early.

The legal ways to end a tenancy before the term is up

There are three routes that let you end a tenancy before a fixed term is up, and they work differently from each other.

The simplest is a mutual written agreement with your landlord, using the LTB’s Form N11. Because both sides agree, there’s no statutory notice period attached, the termination date is whatever date you and your landlord agree to in writing. If more than one person is on the lease, every tenant needs to sign for the agreement to be valid. A landlord who wants their unit back sooner, or who’d rather avoid a vacancy gap, sometimes has real incentive to sign one of these, so it’s worth asking directly rather than assuming the answer is no.

The second route is assigning the lease to a new tenant. An assignment transfers the tenancy to someone else entirely, and once it’s approved, you’re released from the lease and the new tenant takes over your obligations completely. This is different from the third route, subletting, where you give someone else the right to occupy the unit for a defined period but you remain the tenant of record and stay responsible for the tenancy the whole time. Treating these two as interchangeable is a common mistake: an assignment gets you fully out, a sublet does not.

Both an assignment and a sublet need your landlord’s consent, and the law is specific here: a landlord cannot arbitrarily or unreasonably withhold that consent. If your landlord refuses, or simply doesn’t respond to your request, you can apply to the Landlord and Tenant Board for an order finding the refusal unreasonable. There’s also a more direct exit built into the assignment process specifically: if a landlord refuses or fails to respond to a request to assign, you can end the tenancy with 30 days’ written notice, shorter than the standard notice covered further down.

When the law lets you leave faster: documented hardship grounds

Ontario law recognizes one specific hardship route that shortens the standard notice period well below what anyone else gets: a tenant who is a victim of domestic or sexual violence and abuse, or whose dependent child is, can end a monthly, yearly, or fixed-term tenancy with 28 days’ written notice instead of the standard 60. This uses a specific form, the LTB’s N15, and needs to be accompanied by either a relevant court order or the tenant’s own signed statement using the Board’s own Tenant’s Statement form. The landlord is legally required to keep this notice confidential.

This is a genuine, documented legal provision, not a loophole, and it exists specifically because the standard notice periods don’t work for someone in an unsafe situation. It’s also narrow: it applies to violence and abuse as the statute defines it, not general hardship, a job loss, or a change of plans. If this situation applies to you, Tribunals Ontario’s own N15 form and instructions are the right starting point, and the confidentiality requirement means your landlord isn’t entitled to broadcast the reason to anyone else.

What happens if you just leave without following one of these routes

Simply moving out and stopping rent payments, without a signed N11, a completed assignment or sublet, or a qualifying hardship notice, doesn’t end your legal obligations. You generally remain responsible for rent until the unit is re-rented, until the fixed term would have ended on its own, or until a valid statutory ground otherwise applies. That’s the real cost of skipping the process, and it deserves an honest look before deciding to just leave.

The law isn’t entirely one-sided here, though. Landlords have a statutory duty to mitigate damages, meaning your landlord has to take active, reasonable steps to re-rent the unit rather than let it sit empty and bill you for months of vacancy. If a dispute over unpaid rent ends up at the Landlord and Tenant Board, the landlord has to show it actually tried to re-rent the unit; if it can’t, that undercuts its own claim. The moment a new tenant moves in and starts paying, your financial obligation for that unit generally ends. None of this means leaving without notice is free, it usually isn’t, but it also isn’t an open-ended bill for the rest of your original term regardless of what the landlord does.

How much notice you actually need to give

If you’re on a month-to-month tenancy, whether because your original lease was periodic from the start or because a fixed term already lapsed into one, the standard notice to end it is 60 days in writing, and the date you name has to land on the last day of a rental period, the last day of a monthly term, for example, not just any date 60 days out. That’s a meaningfully different situation from ending a fixed term early, which the 60-day notice alone does not do. Ending an active fixed term before its end date requires one of the routes covered above: mutual agreement, assignment, subletting, or a qualifying hardship notice. Confusing the two, giving 60 days’ notice and assuming that alone gets you out of a fixed term with eight months left, is one of the more common and costly mistakes tenants make.

Frequently asked questions

Can I just give 60 days’ notice and leave a fixed-term lease early?

No, not on its own. Sixty days’ written notice is the standard way to end a month-to-month tenancy once you’re in one, either because your lease started that way or because an earlier fixed term already lapsed into a periodic tenancy. It doesn’t, by itself, end an active fixed term before its stated end date. To leave a fixed term early, you need one of the specific routes the law recognizes: a mutual written agreement with your landlord (Form N11), assigning the tenancy to a new tenant, subletting it, or, in a documented hardship situation involving violence or abuse, a shortened 28-day notice. Giving standard notice without one of these in place can leave you still liable for rent on a lease you thought you’d ended.

What’s the actual difference between assigning a lease and subletting it?

An assignment transfers the tenancy to a new tenant entirely, and once it’s properly done, you’re released from the lease and the new tenant takes on full responsibility. Subletting is different: you give someone else the right to occupy the unit for a defined period, but you remain the tenant of record and stay legally responsible for the tenancy the whole time, including if the person you sublet to doesn’t pay or damages the unit. Both need your landlord’s consent, and in both cases that consent cannot be arbitrarily or unreasonably withheld. If your goal is to be fully done with the lease, an assignment gets you there. A sublet doesn’t, it’s meant for a temporary absence where you plan to come back.

Can my landlord refuse to let me assign or sublet my unit?

Your landlord can refuse a specific candidate for a legitimate reason, poor credit or a bad rental history, for example, but they can’t arbitrarily or unreasonably withhold consent to assign or sublet altogether. If a landlord refuses without a reasonable basis, or simply doesn’t respond to your request, you can apply to the Landlord and Tenant Board for an order finding the refusal unreasonable. There’s also a specific shortcut built into the assignment process: if a landlord refuses or fails to respond to a request to assign, you’re entitled to end the tenancy with 30 days’ written notice instead of the standard 60. Keep your request and any response (or lack of one) in writing, since that’s what the Board looks at if it comes to a dispute.

What actually happens if I just move out and stop paying rent?

You generally remain responsible for the rent until the unit is re-rented, until the fixed term would have ended on its own, or until a valid statutory ground otherwise applies, since simply leaving doesn’t end your legal obligations under the lease. Your landlord does have a duty to mitigate, meaning they have to take real, active steps to re-rent the unit rather than leave it vacant and bill you for the full remaining term regardless. If it comes to a claim for unpaid rent at the Landlord and Tenant Board, the landlord has to show it tried to re-rent. That said, this route usually costs more than any of the formal ones above, so try mutual agreement, assignment, or subletting first rather than assuming leaving quietly is simpler.

Is there a faster way out if I’m in an unsafe living situation?

Yes. Ontario law lets a tenant who is a victim of domestic or sexual violence and abuse, or whose dependent child is, end a tenancy with 28 days’ written notice, well short of the standard 60, using the Landlord and Tenant Board’s N15 form. That notice needs to be accompanied by either a relevant court order or your own signed statement on the Board’s Tenant’s Statement form, and your landlord is legally required to keep it confidential. This provision exists specifically because the standard notice periods aren’t workable for someone in this situation, and it applies whether you’re on a fixed term or a periodic tenancy. If this applies to you, Tribunals Ontario’s own forms and instructions are the direct starting point.

Where do I go if my landlord and I disagree about ending my tenancy?

The Landlord and Tenant Board, part of Tribunals Ontario, handles disputes over ending a tenancy, including a refused assignment or sublet request, a disagreement over whether proper notice was given, or a claim for unpaid rent after a tenant leaves. This guide explains the general rules that apply across Ontario; it isn’t advice on your specific tenancy, and the details of your own lease and situation can change how these rules apply. For a live dispute, Tribunals Ontario’s own resources and, where it’s a significant amount of money or a genuinely contested situation, a paralegal or lawyer who handles landlord-tenant matters are the right next step.
