The 7-Day N4 Lands September 21: What Ontario Landlords Must Change That Week

On September 21, 2026, the N4 notice period in Ontario is cut in half. The 14-day notice most landlords have used their entire career becomes a 7-day notice. It is the single biggest procedural gain for landlords in Bill 60, and the week it arrives is going to generate a lot of defective notices.

Here is exactly what changes, what does not, and what you need to do differently that week.

The change in one paragraph

Today, when a tenant fails to pay rent, you serve an N4 Notice to End the Tenancy Early for Non-Payment of Rent. For a monthly or yearly tenancy, the termination date on that notice must be at least 14 days after the notice is given. On September 21, 2026, section 59 of the Residential Tenancies Act is amended so that the minimum becomes 7 days.

That is a full week removed from the front end of every arrears file in the province.

Why one week matters more than it sounds

A week does not sound like much against LTB wait times that still run three to five months for an L1. But the week compounds.

The N4 has to expire unpaid before you can file the L1. Filing a week earlier means your place in the scheduling queue is a week better. In practice, landlords report that filing earlier in a month can shift a hearing date by considerably more than the days saved, because scheduling happens in blocks rather than continuously.

There is also a behavioural effect. A tenant who habitually pays on the twentieth of the month has been able to treat the 14-day N4 as a routine part of the cycle. A 7-day notice removes that cushion, and it changes the conversation.

At a rent of $2,500 a month, one week of arrears is roughly $575. Multiply that across a file that runs ten months and the compounding is real. Our breakdown of the true cost of an N4 and L1 application walks through the full arithmetic.

The transition trap

This is the part that will cost some landlords a hearing.

The amendment applies to notices given on or after September 21, 2026. It does not retroactively rescue a notice you served in August. Section 241.5 of the RTA, a transition regulation power, also comes into force on the same date precisely so the government can specify how in-flight files are treated.

What that means in practice:

• Serve on September 20: the 14-day rule applies. A 7-day termination date makes your notice void.
• Serve on September 22: the 7-day rule applies. You may use it, and you should.
• Served in August, filing in October: your notice was governed by the rule in force when it was given. Do not amend the termination date on an already-served notice.

The single most common reason an otherwise strong arrears file collapses at the LTB is a wrong termination date. That risk spikes during any transition week. If you have a borderline file in mid September, the safest move is often to wait two days and serve under the new rule rather than serve early under the old one.

The other change landing the same day

September 21, 2026 also brings the N12 own-use compensation exception, which lets a landlord avoid the one month rent compensation where the termination date is at least 120 days after notice is given. That is a separate topic with its own arithmetic, and we cover it in detail in our N12 own-use guide.

What has not changed about the N4

The shorter notice period does not simplify anything else. Every other requirement stands.

• The form must be the current Board-approved N4. Since July 1, 2026, section 43 requires notices to be in the form approved by the Board. Retyping the form or reusing a saved 2019 copy is now a materially worse idea than it used to be.
• The arrears figure must be exact. Overstating arrears, including charges that are not lawful rent, or misapplying a deposit will still sink the notice.
• Service must be proper and provable. Personal delivery, mail with the correct deemed receipt rules, or another permitted method, with a Certificate of Service filed.
• The tenant can still void the notice by paying in full. A 7-day window is shorter, but the right to void by payment before the termination date is unchanged.
• Weekly and daily tenancies were already 7 days. This change affects monthly and yearly tenancies.

Your checklist for the week of September 21

1. Download a fresh N4 on September 21 or later. Do not use a stored copy. Confirm the version you are holding reflects the current notice period.
2. Recheck your date arithmetic. Count from the day the notice is given, and account for deemed service rules if you are mailing. A calendar error is the most expensive mistake in this entire process.
3. Do not amend notices already served. If you served under the 14-day rule, let it run. Amending mid-flight creates a defective notice and an argument you will lose.
4. Audit your chronic late payers now. Identify the tenants where you expect to serve in the fall so you are ready to move on day one rather than scrambling.
5. Diarize the date. September 21, 2026. Put it in whatever calendar you actually look at.

Frequently asked questions

When does the 7-day N4 take effect in Ontario?

September 21, 2026. The amendment to section 59 of the Residential Tenancies Act was brought into force by Order in Council as part of the staged proclamation of Bill 60, the Fighting Delays, Building Faster Act, 2025.

Can I use a 7-day termination date on an N4 before September 21, 2026?

No. A notice given before that date is governed by the 14-day rule for monthly and yearly tenancies. A 7-day termination date on a notice served earlier will render the notice void, and the defect is usually fatal at the hearing.

Does the 7-day N4 apply to notices I already served?

No. The rule applies to notices given on or after September 21, 2026. A notice served in August 2026 remains a 14-day notice. Do not attempt to shorten the termination date on a notice already delivered.

Can a tenant still stop the eviction by paying the arrears?

Yes. The right to void an N4 by paying the full amount owing before the termination date is unchanged. The window is simply shorter. If the tenant pays in full within the 7 days, the notice is void and you cannot proceed on it.

How soon after the N4 expires can I file the L1?

You can file the L1 the day after the termination date passes without full payment. Filing promptly matters, because the LTB scheduling queue for an L1 non-payment application still runs roughly three to five months in most regions.

The bottom line

The 7-day N4 is a genuine advantage, and it is worth using from the first day it is available. It is also a transition week where a single miscounted date can cost you six months. The landlords who benefit will be the ones who downloaded a fresh form, counted carefully, and filed the moment the notice expired.

If you have a tenant in arrears heading into September, call us before you serve. A short conversation now is considerably cheaper than a void notice discovered at a hearing in February.
