What the LTB Actually Looks For in an N4 Filing

By Solutions Property Management — Tue Feb 03 2026

An N4 is the first step, not a magic wand. Here's what the Landlord and Tenant Board actually checks before your file moves forward.

The N4 — Notice to End a Tenancy Early for Non-payment of Rent — is the most-served notice in Ontario. It's also the most-messed-up.

If you file an L1 with a defective N4, the LTB will dismiss it. You'll start over. Your tenant lives rent-free for another 60-90 days. Get it right the first time.

**The five things adjudicators check**

1. **The amount is exact.** If the tenant owes $2,412.37 and you write $2,412, it's defective. To the penny. 2. **The termination date is calculated correctly.** For monthly tenancies, the tenant gets 14 days from the date you serve the notice. If you serve on the 3rd, the earliest termination date is the 17th. Not 14 days from the date rent was due. 3. **The rental period matches what's owed.** You list the specific months and amounts. Don't lump. 4. **Service was proper.** Hand-delivery, mail (add 5 days), or leaving with an adult occupant. Sliding it under the door is not proper service under the RTA. 5. **The name on the notice matches the lease.** If the lease says "Jonathan Smith" and the N4 says "John Smith," you have a problem.

**What tenants often do**

Pay the arrears before the termination date. This voids the N4 automatically. That's the point of the notice — it's designed to give the tenant a chance to cure. If they pay in full (including any rent that has come due since), you're back to normal.

**When to file the L1**

The day after the termination date, if arrears haven't been paid. Don't wait. Every week you delay is a week of hearing backlog you're adding to your own case.

None of this is legal advice — talk to a paralegal for anything complicated. But the mechanical stuff above is where 80% of dismissed cases die.
