What the LTB Actually Looks For in an N4 Filing
By Solutions Property Management — Tue Feb 03 2026
Quick answer
The Landlord and Tenant Board (LTB) scrutinizes N4 notices for exactness. Key elements include the precise amount owed, correct termination date calculation (14 days from service), specific rental periods listed, proper service method, and the tenant's name matching the lease. Defects in any of these areas can lead to case dismissal.
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.
Frequently asked questions
What makes an N4 notice invalid at the LTB?
An N4 notice can be deemed invalid if the amount owed is not exact to the penny, the termination date is miscalculated, rental periods are not specified, service was improper (e.g., sliding under a door), or the tenant's name on the notice doesn't match the lease. Any of these errors will lead to dismissal.
How should I calculate the termination date for an N4 notice?
For a monthly tenancy, the termination date on an N4 notice must be at least 14 days from the date you *serve* the notice to the tenant, not 14 days from when rent was due. For instance, if served on the 3rd, the earliest termination date would be the 17th of that month.
What happens if a tenant pays rent after receiving an N4 notice?
If a tenant pays all outstanding rent arrears, including any rent that has become due since, before the termination date specified on the N4 notice, the notice becomes void. The tenancy continues as normal, as the N4's purpose is to give the tenant a chance to 'cure' the non-payment.
When should I file an L1 application with the LTB after serving an N4?
You should file the L1 application the day after the termination date stated on the N4, provided the arrears have not been paid in full. Prompt filing is crucial because any delay adds to the time it takes for your case to be heard due to LTB backlogs.
