The N4 Notice in Ontario: 2026 Step-by-Step Landlord Guide

The N4 — Notice to End a Tenancy Early for Non-payment of Rent — is the most-used and most-botched form in Ontario landlording. Served correctly, it starts a clean path to either payment or an LTB order. Served with the wrong amount, the wrong date, or the wrong method, it's void, and you lose weeks of rent finding out. Here's the complete 2026 guide to getting it right the first time.

What the N4 Is (and Isn't)

The N4 is a Landlord and Tenant Board form that tells a tenant: pay the rent you owe within the notice period, or the landlord may apply to the LTB to end the tenancy. Two things it is not: it is not an eviction — only the Board can order that — and it is not an LTB filing. Serving an N4 costs nothing and starts no case; it simply opens the legal door to filing an L1 application later.

The N4 is also, by design, forgiving to the tenant: if they pay everything owed before the termination date, the notice becomes void and the tenancy continues as if nothing happened. In practice, the majority of properly served N4s end exactly that way — with payment, not a hearing. That's a feature: your goal is rent, not a court date.

Use the current version of the form from Tribunals Ontario, and if there are multiple tenants on the lease, name all of them.

Getting the Amounts and Dates Right

The arrears amount may include rent only. No NSF bank charges, no utilities, no parking billed separately, no late fees (which aren't lawful in Ontario anyway). Include only lawful rent that is actually overdue on the date you sign the notice. If a tenant paid partially, subtract it. An inflated figure — even by $50 — makes the notice void.

The termination date must give enough time. For monthly and yearly tenancies (the vast majority), the termination date must be at least 14 days after the notice is served. For daily or weekly tenancies, it's 7 days. Count carefully: if you serve by mail, add 5 days for deemed service; by courier, add 1 day.

Serving the N4 Validly

Permitted service methods under the LTB rules include: handing it to the tenant directly; handing it to an apparently adult person in the unit; leaving it in the tenant's mailbox or where mail is ordinarily delivered; sliding it under the door or through a mail slot; sending it by courier (add 1 day); or mailing it (add 5 days). Email service is only valid where the parties have a written consent to email service that complies with LTB rules.

Posting it on the door is not valid service for an N4. It's a common mistake, and it voids everything that follows.

Always complete a Certificate of Service (form) the same day — the Board will ask for it at the L1 stage, and “I'm pretty sure I served it around the 3rd” does not survive a hearing. Photograph the served notice in place when practical. Professional managers document service as a routine habit; it's part of what you're buying with professional lease management.

After the Termination Date: Filing the L1

If the termination date passes without full payment, you can file an L1 application — as early as the very next day. In 2026 the L1 costs $186 filed online or $201 on paper, and online filing through Tribunals Ontario's portal is both cheaper and faster to process. Unlike conduct notices such as the N5, the N4 has no 30-day filing deadline after the termination date — but don't sit on it; delay compounds arrears and reads poorly at a hearing.

From filing, expect roughly 2–4 months to a merits hearing in most Ontario regions in 2026. At the hearing, your evidence is the rent ledger, the N4, the Certificate of Service, and the lease. Orders typically give the tenant 11 days to pay everything (including your filing fee) or face enforcement; only the Court Enforcement Office can physically enforce an eviction order, for roughly $350–$450.

Strategy: Serve Early, Stay Professional

The best-run rental operations serve the N4 promptly — often within 2–3 days of a missed payment — while simultaneously communicating with the tenant like a professional: “The notice protects the timeline; if you can pay by Friday, it's void and we move on.” This isn't aggressive; it's how you avoid choosing later between forgiving a month's rent and losing an extra month to a late-served notice.

Pair the N4 discipline with prevention: automated rent collection that flags failures on day one, tenant screening that verifies income before move-in, and clean ledgers that make any future hearing straightforward. D&D Property Management runs this exact protocol for owners across Kitchener-Waterloo, Cambridge and Guelph — notices served correctly, filings coordinated at $350 plus the LTB fee, and documentation the Board actually accepts.

Frequently Asked Questions

How many days' notice does an N4 require in Ontario?

At least 14 days for monthly or yearly tenancies, and 7 days for daily or weekly tenancies. The clock starts from valid service — and if you serve by mail you must add 5 days (1 day for courier) before counting the notice period.

What can I include in the N4 arrears amount?

Only lawful rent that is overdue. You cannot include NSF charges, late fees, utilities billed separately, parking, or damage costs. Including anything other than rent — or getting the math wrong — makes the notice void and forces you to start over.

What happens if the tenant pays after receiving an N4?

If the tenant pays all arrears listed (plus any rent that has since come due) before the termination date, the N4 is void and the tenancy simply continues. Most properly served N4s end in payment. If they pay only part, the notice stands and you may still file an L1 after the termination date.

Can I email an N4 notice to my tenant?

Only if you have written consent to email service that meets LTB requirements. Otherwise use a permitted method: personal delivery, delivery to an adult in the unit, the mailbox, under the door, courier (add 1 day) or mail (add 5 days). Taping it to the door is not valid service for an N4.

How soon can I file an L1 after the N4 termination date?

The day after the termination date, if arrears remain unpaid. The L1 costs $186 online ($201 on paper) in 2026, and hearings are currently scheduled roughly 2-4 months out in most regions — one more reason to serve the N4 promptly rather than waiting out of politeness.
