Key takeaways
  • If you and your partner signed one tenancy agreement together, the landlord can pursue either of you for the whole rent.
  • Moving out does not end your tenancy: a monthly tenant generally gives 60 days' notice on Form N9, and a fixed-term lease cannot end before its term is over.
  • A tenant who is a victim of sexual or domestic violence and fears harm can end a tenancy on 28 days' notice using Form N15, with a Tenant's Statement or a restraining order or peace bond issued within the last 90 days.

When a couple who rent together separate, one person often moves out quickly while the other stays. It is easy to assume that leaving the home also means leaving the lease. In Ontario, that is usually not how it works, and the landlord may still expect rent from both of you.

This article explains how rent liability, the remaining partner's position and the main ways of ending a tenancy generally work. Your lease, your relationship status and your safety situation can all change the answer, so treat this as a starting point.

Who owes the rent when you share one lease

Under a joint tenancy, where all tenants share a single tenancy agreement, the tenants are jointly and severally liable for the entire rent. That means the landlord can pursue any one of them for the full amount.

In practice, if your partner moves out and stops paying, the landlord is not limited to asking your partner for half. Whatever the two of you agree between yourselves about splitting rent, that private arrangement does not by itself change what the landlord can claim.

Family law may allocate debts between spouses when property is divided, but that is a separate question from what a landlord can demand under the lease. It is worth keeping the two apart.

If your partner leaves and you stay

Landlord and Tenant Board guidance says that if a tenant moves out without giving notice or agreeing to end the tenancy, and the tenant's spouse stays in the unit as their principal residence, the spouse is included in the definition of tenant under the Residential Tenancies Act, 2006, unless a listed exception applies.

That guidance speaks of a spouse. Whether it reaches you if you and your partner are not married depends on your situation, so it is worth confirming with a lawyer.

The spouse does not become a tenant in listed situations. Two of them are:

If you are the one staying, it helps to confirm in writing with the landlord how they see your position. Whether another exception applies to you depends on your facts, and a lawyer can confirm.

Ending the tenancy: notice, agreement and fixed terms

Moving out is not the same as ending a tenancy. A tenant ending a monthly tenancy must give at least 60 days' notice on Form N9, with a termination date on the last day of a rental period. For a fixed-term lease, the termination date cannot be earlier than the last day of the term. You and the landlord can also agree to end the tenancy using Form N11.

A tenant who leaves without proper notice may owe rent until the earlier of the date the unit is re-rented or the earliest termination date that would have applied with proper notice.

SituationGenerally what applies
Monthly tenancyForm N9, at least 60 days' notice, ending on the last day of a rental period
Fixed-term leaseCannot end earlier than the last day of the term
Landlord and tenant agreeForm N11
Left without noticeRent may be owed until re-rented or the earliest proper termination date, whichever is first

When safety is the concern: Form N15 and restraining orders

A tenant who, or whose child living with them, is a victim of sexual or domestic violence and fears harm can end the tenancy on 28 days' notice using Form N15 at any time. The notice must be accompanied by a Tenant's Statement, or by a restraining order or peace bond issued within the last 90 days.

If you share the tenancy, note this point: if the N15 is not signed by all the tenants in a joint tenancy, the tenancy continues for the tenants who did not sign it. So the person who signs ends their own part of the arrangement, but the others may remain tenants.

Whether you can stay in a rented home after abuse is a separate question that depends on your lease and your situation, so it is worth confirming with a lawyer. A person abused by a spouse or partner can ask the court for a restraining order. It can require the person to stay away generally, or from specific places such as the home, workplace or the children's school. If you are in danger, call 911 or your local police immediately.

Matrimonial home rules and renters

The Family Law Act defines a matrimonial home as every property in which a spouse has an interest and that is, or was at the time of separation, ordinarily occupied by the spouses as their family residence. If you are married, a court can order that one spouse be given exclusive possession of a matrimonial home, regardless of who owns it.

Those possession rules apply to married spouses only. Ontario's guidance tells people who are not married to contact a lawyer about their rights and options regarding the home. Because the definition depends on having an interest in the property, how it applies to a rented home is something to confirm with a lawyer rather than assume.

What to do next

Frequently asked questions

Can my landlord ask me for the full rent if my ex moved out?

If you both signed one tenancy agreement, yes. Joint tenants are jointly and severally liable for the entire rent, so the landlord can pursue either of you.

Does moving out end my lease?

No. A monthly tenant generally gives at least 60 days' notice on Form N9, and a fixed-term lease cannot end before the last day of its term. You and the landlord can also agree to end it using Form N11.

What if I leave without giving notice?

You may owe rent until the unit is re-rented or until the earliest termination date that proper notice would have allowed, whichever comes first.

Can I leave quickly if I am afraid of my partner?

A tenant who is a victim of sexual or domestic violence and fears harm can end the tenancy on 28 days' notice using Form N15, with a Tenant's Statement or a restraining order or peace bond issued within the last 90 days. If not every joint tenant signs, the tenancy continues for those who did not.
