Can I break a fixed-term lease early in Ontario?

Not simply by giving notice. A fixed-term lease binds you until the end of the term. Your legal options are to assign the tenancy, sublet the unit, or reach a mutual agreement to end early (Form N11). If you leave anyway, your landlord must make reasonable efforts to re-rent, and you're only liable until it's re-rented or the term ends.

Will breaking a lease hurt my credit?

Breaking a lease itself isn't reported to credit bureaus. But if your landlord obtains an LTB order for money you owe and you don't pay, that debt could eventually affect your credit if it goes to collections. Communicating and using assignment or subletting avoids this.

Can my landlord charge a penalty for breaking my lease?

No. Ontario doesn't allow lease-break penalties or fees beyond your actual rent obligation (reduced by the duty to mitigate). A clause requiring two or three months' rent as a penalty is not enforceable under the Residential Tenancies Act.

How to Break a Lease in Ontario (Legally)

A job across the country, a breakup, a place you can no longer afford — life happens mid-lease. In Ontario you can't just give notice and walk away from a fixed term, but you have real, legal options that limit what you owe. Here's how to do it right.

First: You Can't Just Give Notice

A fixed-term lease (say a one-year lease) binds you for the full term. Giving 60 days' notice on an N9 does notlet you leave early — that form only ends a month-to-month tenancy or sets a move-out date for the end of your term. So the real question isn't whether you can serve notice; it's which of the legal exits below fits your situation.

The good news: Ontario law limits what you can be charged, and outright lease-break "penalties" are not enforceable.

Option 1: Assign the Tenancy (Cleanest Exit)

An assignmenttransfers your entire tenancy to a new tenant and ends your responsibility once the landlord consents. It's usually the cleanest way out of a fixed term. Your landlord can't unreasonably refuse, can only charge their actual out-of-pocket costs (like a credit check), and if they refuse unreasonably or don't respond within seven days, you can give notice to end on 30 days.

See the full mechanics in our subletting and assignment guide.

Option 2: Sublet Until the Term Ends

A subletputs someone else in the unit for a period while you remain the tenant and plan to return before the term ends. It suits a temporary move, but you stay liable to the landlord, so choose a subtenant carefully. You can't charge them more than your lawful rent.

Option 3: Agree to End Early (Form N11)

If your landlord is willing, you can both sign a Form N11 — Agreement to End the Tenancy. This is voluntary: a landlord can't force you to sign one, and you shouldn't sign under pressure. If your landlord already has a waiting list or a higher-paying tenant lined up, they may happily agree. Get the agreed move-out date in writing. See our N11 explainer.

Option 4: Leave and Rely on the Duty to Mitigate

If none of the above works and you simply have to go, know this: your landlord cannot leave the unit empty and bill you for the whole remaining term. They have a legal duty to mitigate— to make reasonable efforts to re-rent. You're only on the hook for rent until a new tenant moves in (or the term ends), plus any genuine advertising costs.

Give written notice of your intent, keep records, and if the landlord later claims unpaid rent at the LTB, you can argue they didn't try to re-rent. This is the riskiest route — get advice first from a tenant legal clinic or paralegal.

Special Situations

Experiencing violence or abuse? You can end your tenancy on 28 days' notice using Form N15, even mid-term.
Serious unaddressed maintenance? That's not an automatic exit, but it may support a T6 application and negotiation.
Month-to-month already? You're not "breaking" anything — just give 60 days' notice on an N9.
