Rent is late in Ontario: what happens, day by day

01Rent is late the day after it is due

If rent is due on the first and it is not paid on the first, it is late on the second. The Residential Tenancies Act does not give a grace period, and neither does the standard lease.

That does not mean you should serve a notice on the second. Most late rent is a payday that moved or a transfer that failed, and one message usually fixes it. But it does mean the clock is yours to start whenever you decide to.

The important thing is to be consistent. If you always wait until the fifth, wait until the fifth for everyone. A pattern you can describe is worth more at a hearing than a pattern you cannot.

02The N4, and what goes on it

The form is the N4, Notice to End your Tenancy Early for Non-payment of Rent. It is free from the Landlord and Tenant Board.

Section 59 of the Act says the notice sets out the amount of rent due. Rent. Not the fee your bank charged you for the returned payment, not the twenty dollars you are allowed to charge for an NSF cheque, not the cost of a repair you are arguing about. Those may be recoverable, but they are not rent, and putting them in the rent figure is how an N4 gets thrown out.

The notice also has to give a termination date, and the number of days depends on when you serve it.

Right now, a notice given for a monthly tenancy has to give a termination date no earlier than the 14th day after it is given. For a daily or weekly tenancy it is the 7th day.

On September 21, 2026, that changes. Section 59 is replaced, and the termination date becomes no earlier than the 7th day after the notice is given, for every tenancy. The rule that applies is fixed by the day you serve, not the day of the hearing.

03Voiding is the word that decides the file

An N4 is not an eviction. It is a demand with a deadline, and the tenant can make it disappear.

The notice itself tells the tenant they can avoid the tenancy ending by paying, on or before the termination date, the rent set out in the notice plus any rent that has come due since.

Section 59 goes further. The notice is void if the tenant pays the arrears, plus the rent that would have come due by the day they pay, at any time before you apply to the Board. So a tenant who pays late but pays in full, before you file, has ended the matter.

This can happen repeatedly, and for a lot of landlords it does. Serve, get paid, serve again next month. That is frustrating but it is not a dead end. Persistent lateness is its own ground, on a different form, with 60 days notice ending on the last day of a rental period. The evidence for it is the paid-on dates, so keep them.

04The timeline, day by day

Here is what the calendar looks like for a monthly tenancy where rent of $2,100 is due on the first and nothing arrives. This example uses the 7 day period that applies to notices given from September 21, 2026.

Pick the form, get the earliest lawful date

Almost every notice thrown out at the Landlord and Tenant Board is thrown out on a date, not on the facts. Two things move that date: mail adds five days before the clock even starts, and some forms have to land on the last day of a rental period.

Notice periods are from the Residential Tenancies Act, 2006 and O. Reg. 516/06. This gives you the earliest date the Act allows. It does not tell you whether you have grounds, and it is not legal advice.

05After you file

Once the L1 is filed, paying no longer voids the notice automatically. The tenant has other routes, and the Board has a wide discretion, but the automatic void under section 59 is gone.

At the hearing the Board can order the tenant to pay, order eviction, or refuse eviction and give the tenant time. Section 83 lets the Board delay or refuse an eviction where it would be unfair not to. A tenant who has paid most of what is owed and can show the rest is coming often gets that.

You are not limited to a tenant who is still there. Section 87 lets you apply for arrears while the tenant is in possession, or up to one year after they stop being in possession. A former tenant who left owing money is not out of reach for a year.

One rule has no exceptions. You cannot change the locks, remove belongings, or shut off a service to force someone out. Only the Sheriff enforces an eviction order, and a lockout turns a file you were winning into a tenant application you will lose.

06What to do when rent does not arrive

There is a notice date calculator on this site under /resources/n4-form-ontario that works out the termination date for the rule in force on the day you serve.

How TenantBay helps: the arrears figure on the N4 and the schedule on an L1 come from the payment records you already keep, and the notice date is set by the rule in force the day you serve rather than the one you remember.

• Send one plain message the day after. Most late rent is fixed here and costs nothing.
• Decide your own trigger date and apply it to everyone. Write it down so you are not deciding under pressure.
• Recalculate the amount owing on the day you actually serve, not the day you drafted the form. Rent that came due in between belongs on it.
• Put only rent on the N4.
• Record how you served it, when, and to whom. That single note is what the Board asks for first.
• Keep paying attention to the paid-on dates even when the money always arrives. That record is the whole case for a persistent lateness notice later.
