Form N9 in Ontario: How a Tenant Ends a Tenancy, and When the Date Is Wrong

This article provides general information about the N9 form in Ontario as of October 2026 and is not legal advice. Notice periods and procedures are drawn from the Residential Tenancies Act, 2006, S.O. 2006, c. 17 (consolidated 21 September 2026), the Legislation Act, 2006, and the Landlord and Tenant Board's forms, Rules of Procedure and guidelines.

The N9 form Ontario tenants use to end a tenancy fits on one page, and only one box on it decides how much rent you will pay before you are free: the termination date. Write a day the law accepts and you leave when you planned. Hand it over a day late, or pick a date in the middle of a rental period, and the same notice can cost you an extra month.

Most of the trouble people run into with an N9 has nothing to do with the form itself. It comes from the calendar: when the rental period ends, which day the notice counts as given, and what February does to the arithmetic. This guide takes the form box by box, then the calendar, then the mistakes, and then the exits that let you leave sooner than the N9 allows. It sits under our wider guide to the Landlord and Tenant Board in Ontario, which covers what happens once a file reaches the Board.

If your situation already has a dispute attached, such as a landlord claiming months of rent after you left, the landlord and tenant lawyers and paralegals on Olanur can look at the dates with you before anything is signed or filed.

N9 form Ontario: the short answer

The N9 is the Landlord and Tenant Board's form for a tenant who wants to move out, and the date on it has to meet a notice period and land on the right day.

• Month to month: at least 60 days of notice, and the date must be the last day of a rental period, usually the last day of a month (Residential Tenancies Act, 2006, s. 44(2)).
• Weekly or daily: at least 28 days, again ending on the last day of a rental period (s. 44(1)).
• Fixed-term lease: at least 60 days before the lease ends, with the lease's end as the termination date. Miss that window and the lease simply carries on month to month (ss. 38(1), 44(4)).
• How days are counted: the day you give the notice does not count and the termination date does. A notice sent by mail counts as given on the fifth day after mailing (s. 191(3)).
• If the date is wrong: the notice does not quietly fix itself. A tenant who leaves on a short notice can owe rent up to the earliest date a proper notice could have named, unless the unit is re-rented sooner (s. 88).

Four boxes and a signature: what the N9 actually asks

The N9 form Ontario's Landlord and Tenant Board publishes today is version v. 01/04/2022, the Form N9, Tenant's Notice to End the Tenancy, and the law asks it to do three things: identify the unit, state the termination date, and carry a signature (s. 43(1)). Everything else on its three pages is instructions.

To and From. The landlord's name goes in the first box. The second box asks for the tenant's name and tells you to "include all tenant names", which matters if two of you signed the lease and only one of you is filling in the form.

Address of the rental unit. Write the full address, including the unit number. A notice that names the wrong unit is the kind of error the Board has had to rule on.

The termination date. The form prints the sentence for you: "The last day of my tenancy will be ___. This is the termination date." The boxes underneath read dd/mm/yyyy, day first. Thirty April 2027 is written 30/04/2027, not 04/30/2027. Writing the month first is an easy habit to bring from elsewhere, and while the Board has treated a reversed day and month as a harmless clerical error in a case where nobody could have been confused, that was a judgment made afterwards about someone else's notice. It is cheaper not to need one.

Signature, page 3. Tick whether you are the tenant or a representative, print your name and phone number, then sign and date it.

The form does not ask why you are leaving, and you do not have to say. It also cannot be one of the papers you sign the day you rent the place: a tenant's notice given at the start of a tenancy, or as a condition of getting it, is void (s. 37(4)). The exceptions are some post-secondary student housing (s. 37(6) and (7)) and, as the form's own instructions note, certain care homes that provide rehabilitative or therapeutic services.

The date is the whole form

The termination date has to satisfy two tests at once: enough days between the day the notice is given and the date, and a date that ends a rental period. Most failed N9s pass one test and fail the other.

The count. Ontario's Legislation Act, 2006, s. 89(3), settles how "at least 60 days" is measured: leave out the day the first event happens, count the day of the second, even where the law says "at least". The Landlord and Tenant Board applies the same rule in Rule 1.13 of its Rules of Procedure. So a notice handed to the landlord on 1 March can end the tenancy on 30 April, exactly 60 days later.

The landing day. If rent is due on the 1st, every rental period ends on the last day of a month. If rent is due on the 15th, each period ends on the 14th, and that is the only day of the month your N9 can name. On a weekly tenancy paid every Monday, the termination date has to be a Sunday, which is the Board's own example on the form.

The day it counts as given. The clock starts when the notice is given, not when you sign it. Handing it to the landlord, to an employee with authority over the building, or leaving it in the landlord's mailbox all count that day (s. 191(1)). The Board's Rule 3.9 deems a courier delivery served the day after you give it to the courier, or the next day that is not a holiday, and mail is deemed given on the fifth day after mailing. Email counts the day it is sent, but only where the landlord has agreed in writing to receive documents by email, for example in the standard lease or on the Board's Consent to Service by Email.

The tool below runs those rules for you. Pick your tenancy, the reason you are leaving, the day you plan to hand the notice over and how it will travel, and it returns the earliest date you can write, printed in the form's own boxes.

Why the second of the month costs a month

On a month-to-month tenancy with rent due on the 1st, the notice you actually give is rarely exactly 60 days. It swings between 60 and 90 depending on the day you hand the form over, with two exceptions covered below, and the jump happens overnight.

The chart traces that for every hand-over day from November 2026 to October 2027, computed straight from the statute. Handed over on 1 March 2027, an N9 can end the tenancy on 30 April. Handed over on 2 March, the earliest date becomes 31 May, because 30 April is now 59 days away and the next period ends a month later. One day of delay buys 31 more days of rent.

Two patterns are worth taking from it. The cheapest hand-over day is the 1st in ten months of the year. In December and July, when that month and the next both have 31 days, the 2nd still works. The other is the February rule. Because February is short, a tenant who gives notice by 1 January can leave at the end of February, and one who gives notice by 1 February can leave at the end of March. In 2027 that is 59 days from 31 December or 31 January, and 58 days from 1 January or 1 February, all deemed to be 60 days' notice under s. 44(5). Those four hand-over days are the only ones in the year when a month-to-month tenant can give fewer than 60 days and still be on time.

Consider a tenant renting a one-bedroom in Hamilton at $1,850 a month, rent due on the 1st, who signs for a new place starting 1 May. If the N9 reaches the landlord on 1 March, the tenancy can end on 30 April and nothing overlaps. If it goes in the mail on 1 March instead, it counts as given on 6 March, the earliest date jumps to 31 May, and that is $1,850 for a month in an apartment nobody is living in.

Six date problems tenants actually have

Each of these is a version of the same question: which days does the law accept, and which one do you want?

The lease ends, and you want to leave when it does

A fixed-term lease does not end by itself in Ontario. If neither side gives notice, it becomes a monthly tenancy on the same terms (s. 38(1)), so leaving on the lease's last day still takes an N9 given at least 60 days before it. The Board's own brochure on how a tenant can end a tenancy gives the example: with a lease ending 31 August and rent due on the 1st, a notice given on 20 June can end the tenancy on 31 August, but a notice given on 31 July cannot, and the earliest date becomes 30 September.

You are month to month and just found a place

This is the 60 days and the last day of a period, nothing more. The pitfall is the start date of the new place, not the old one. If the new lease begins mid-month, the old tenancy still has to end on a period's last day, so the overlap is usually unavoidable unless the landlord agrees to something else.

You want to leave in the middle of a month

An N9 cannot do that on an ordinary monthly tenancy. The termination date has to end a rental period. What can do it is an agreement with the landlord, covered below, or one of the exits in the table that are allowed to land on any day.

Your rent is due on the 15th

Then every period ends on the 14th, and the N9 has to name a 14th. Say a tenant in Mississauga pays on the 15th and hands over the notice on 10 October 2026. The earliest date is 14 December 2026, 65 days later. Handed over on 16 October, it becomes 14 January 2027.

The landlord says a shorter date is fine

A landlord can agree to end the tenancy on any date, and the law treats that as an agreement rather than a notice (s. 37(3)). Agreements can be made out loud, but the Board recommends writing them down, and the usual way is Form N11, Agreement to End the Tenancy. Our guide to eviction notices in Ontario explains why an N11 gives the landlord a fast route to an eviction order if you do not leave on the agreed day. A text saying "sure, go whenever" is a weaker record than a signed N11 if the two of you later disagree about what was promised.

You are buying a home and the closing date is fixed

A purchase closing does not move the notice rules. Count back from the closing: on a monthly tenancy the date to aim for is the end of the rental period just after it, with 60 days of notice before that. Lining the two up early saves paying rent and mortgage on the same month, and it is one of the questions worth raising when you budget for the real estate lawyer fees in Ontario that come with the purchase.

Whatever the situation, keep proof of the day the notice was given. A dated photo of the hand-off, a courier receipt or a reply from the landlord settles the one fact everything else is counted from.

Does an email count instead of an N9?

An email or a text that says you are moving out is not the N9 form Ontario law expects, and it is a risky substitute. The Act requires a tenant's notice to be in the form the Board approves, naming the unit and the termination date and signed by the tenant (s. 43(1)), and the Board's brochure tells tenants to use the N9, as does CLEO's plain-language guide to moving out and giving notice.

There is a safety net, but it is not one to plan around. Section 212 says substantial compliance with the Act's requirements for notices is enough, and since 2024 it adds that an error does not defeat a notice unless it significantly prejudices a party's ability to take part in a proceeding. Whether an informal message clears that bar is decided later, by a Board member, on the facts.

Emailing the N9 itself is different. It counts as given the day it is sent, provided your landlord agreed in writing to receive documents by email. Without that consent, use one of the other methods, or send it both ways and keep the earlier, provable one.

When the date on your N9 is wrong

A wrong date on an N9 form Ontario landlords receive does not cancel the move, but it moves the money. The Act decides what a tenant owes by asking what a correct notice would have said.

Leaving on a short notice. If you vacate after giving a notice that did not comply with the Act, rent is owed for the period ending on the earliest termination date that a proper notice, given that day, could have named (s. 88(1), rule 1). If you leave without any notice at all, the count runs from the day the landlord knew, or ought to have known, that you had gone (rule 2).

Two limits on that bill. If the landlord re-rents the unit, you are not liable past the day the new tenant is entitled to move in (s. 88(3)). And the landlord has a duty to take reasonable steps to keep the loss down, which the Board considers when it sets the amount (ss. 16, 88(4)).

Consider a couple in Ottawa paying $2,300 a month who leave at the end of February 2027 on an N9 handed over on 15 January. A proper notice given that day could not have ended the tenancy before 31 March 2027, so up to one month of rent can be claimed. If the landlord shows the unit right away and a new tenant is entitled to move in on 15 March, the claim is capped at the rent for the period ending that day.

How the landlord collects it. A landlord claiming money from a former tenant files an L10 at the Board, which costs $201, or $186 through the Tribunals Ontario Portal, on the Board's filing and fees page. The Board can order up to the greater of $10,000 and the Small Claims Court limit (s. 207(1)). A landlord who writes first is often sending something close to a demand letter, and a reply that sets out the correct dates, the re-rent date and your last month's rent can end the matter there.

On the landlord's side, a wrong date usually sinks the notice. The Board's Interpretation Guideline 10, updated 21 September 2026, says a notice must state the correct termination date "without doubt or condition", and that an incorrect date "likely makes a Notice invalid". The guideline is written mainly about landlords' notices, but it shows how seriously the Board treats the date box.

Your last month's rent. If you paid a rent deposit, the landlord has to apply it to the last rental period before the tenancy ends (s. 106(10)). On a valid N9, that usually means the final month is already paid. Our guide to tenant rights in Ontario covers what a deposit can and cannot be used for.

If you change your mind after giving an N9

Once given, an N9 belongs to both of you. You can stay past the termination date only if the landlord agrees, and the landlord can act on it straight away.

The L3. A landlord can apply to the Board for an eviction order based on your N9 as soon as you give it, without notice to you, and no later than 30 days after the termination date (s. 77(1), (3)). The order cannot take effect before the date on your notice (s. 77(5)). The filing fee is the same $201, or $186 online.

The motion to set it aside. A tenant who receives that order has 10 days from the day it is issued to ask the Board to set it aside (s. 77(6)), and the Board charges nothing for that motion. Since 21 September 2026 the test has narrowed: the Board's operational update says it may cancel an order based on a tenant's notice "only if the LTB is satisfied that doing so would not be unfair", and it "cannot consider changes in the tenant's circumstances" that happened after the notice was given. A lost job or a cancelled lease on the new place after you handed over the N9 no longer counts.

Two quieter rules. A landlord who accepts rent after your notice does not cancel it, unless the two of you agree otherwise (s. 45). And if you stay and the landlord does nothing, the notice becomes void 30 days after its termination date (s. 46(1)), so the tenancy continues. Neither rule is a plan. Talking to the landlord before the date, and writing down what you agree, is.

While the notice runs, the landlord can show the unit to prospective tenants without written notice, between 8 a.m. and 8 p.m., after informing you or making a reasonable effort to (s. 26(3)). Anything you leave behind after the termination date can be disposed of, as the N9's own instructions warn.

Ways out that the N9 does not cover

Some exits are faster than 60 days, and some do not use the N9 at all.

Assigning the lease. You can ask the landlord to let someone take over your tenancy (s. 95). The landlord can refuse to allow any assignment at all, which opens the exit below, but cannot arbitrarily or unreasonably turn down a particular person while allowing assignment in principle (s. 95(3), (5)). If the landlord refuses, or does not answer within seven days, you can give an N9 within 30 days of the request, with at least 30 days' notice, or 28 on a daily or weekly tenancy, on any day of the month (ss. 95(4), 96(2)). A tenant who thinks a refusal was unreasonable can file an A2 application, which costs $53. The brochure notes that tenants in subsidized, public or non-profit housing, superintendents' units and housing provided by an educational institution do not have this right.

Subletting is not leaving. A sublet needs the landlord's consent, which cannot be unreasonably withheld, but you remain liable to the landlord for the whole tenancy (s. 97). It suits a temporary move, not a permanent one.

After a landlord's N12 or N13. If your landlord has served an own-use or renovation notice, you can leave earlier on at least 10 days' notice, on any day before the landlord's date (ss. 48(3) and (4), 49(4) and (5), 50(4) and (5)). The N9 is the form for that too.

Fear of domestic or sexual violence. A tenant on a monthly, yearly or fixed-term tenancy who, or whose child, has experienced violence or abuse can end the tenancy on 28 days' notice using Form N15, on any day (s. 47.1). It goes with either the Board's tenant statement or a copy of a qualifying court order issued within the previous 90 days, and the landlord must keep it confidential (s. 47.4). If you are separating at the same time, our guide to separation agreements in Ontario covers the other paperwork that usually follows.

No standard lease. Most tenancy agreements made on or after 30 April 2018 have to use Ontario's standard lease. If yours does not, and the landlord has not provided one within 21 days of your written demand, or provides one that you decide not to sign within 30 days, you can end even a fixed-term tenancy on 60 days' notice at the end of a rental period (s. 47.0.1).

The landlord broke the rules. The Board can end a tenancy early on a tenant's application where the landlord has failed to meet obligations such as maintenance, lawful entry or vital services, after a hearing. That is a tenant application, not a notice.

When it helps to talk to someone

Most N9s need nobody but the tenant and a calendar. A few situations are worth a second look before the form goes in.

• A fixed term with months left and a move you cannot delay, where an assignment, an N11 or an N15 might apply.
• A landlord's claim for rent after you have left, especially one that ignores a re-rent date.
• An L3 eviction order you did not expect, where the 10-day window to respond has already started.
• A joint tenancy where only one tenant is leaving.
• A move tied to a purchase closing, where a missed date costs two housing payments at once.

A licensed paralegal can represent you at the Board on landlord and tenant matters, and our guide to paralegal or lawyer for the LTB sets out where each one fits and what the representation costs. Before paying anyone, the Law Society lawyer and paralegal lookup confirms the licence in a minute. Our breakdown of what a lawyer costs in Ontario covers the fee models you are likely to be quoted.

Frequently asked questions

Before you hand it over

This week, find three dates: the day your rent is due, the day you can realistically put the notice in your landlord's hands, and the day your next home starts. The date finder turns the first two into the earliest date the law accepts; the third tells you whether that works. Fill in the N9 form Ontario requires with the date written day first, keep proof of delivery, and keep a copy of the signed form. If the dates do not line up, or the landlord is already talking about money, the landlord and tenant lawyers and paralegals on Olanur can help you work out the cheapest way to leave.
