N5 Notice Ontario: Eviction for Damage, Interference & Overcrowding
Your tenant punched a hole in the drywall. Or their all-night parties have three other tenants threatening to leave. Or they've moved six people into a bachelor unit. The N5 is your tool. Here's how to use it without getting it thrown out.
When to Use an N5
The N5 is the Notice to End a Tenancy Early for tenant behaviour that goes beyond not paying rent. It covers three distinct grounds, and you need to pick the right one on the form.
Ground 1: Substantial Interference
This is the most common reason landlords reach for the N5. Your tenant is making life miserable for other tenants, or for you.
What qualifies? Repeated loud parties at 2 AM. Screaming matches that other tenants can hear through the walls. Harassing neighbours in the hallway. Smoking in a non-smoking building (repeatedly, not once). Blocking shared laundry or parking. Running an illegal business out of the unit that brings strangers through the building at all hours.
What does not qualify? A single noise complaint. A one-time argument. A tenant who plays music at a reasonable volume but your other tenant has thin skin. The word "substantial" is doing heavy lifting here. The LTB wants a pattern, not a bad weekend.
Ground 2: Willful or Negligent Damage
The tenant (or their guest) damaged the rental unit or the building. Holes in walls. Broken appliances from misuse. Flooding from leaving the tub running. A guest who kicked in the front door.
"Willful" means they did it on purpose. "Negligent" means they were careless enough that a reasonable person would have known better. Both count.
Normal wear and tear does not count. Faded paint, worn carpet, a loose doorknob after 5 years? That's your cost of doing business.
Ground 3: Overcrowding
The unit has more occupants than what's allowed under health, safety, or housing standards. Municipal bylaws set the limits. In most Ontario municipalities, this is based on square footage per occupant.
You can't just say "too many people." You need to reference the specific bylaw they're violating. Call your local municipal bylaw office and get a written determination. That document becomes your evidence.
First N5 vs Second N5
This is where the N5 gets tactical. The rules are completely different depending on whether it's the tenant's first or second N5.
First N5
The Warning Shot
- Termination date: At least 20 days after serving
- Voiding period: Tenant has 7 days to fix the problem
- If voided: The N5 dies. You cannot file an L2 based on it.
- If not voided: File an L2 after the termination date passes.
Second N5
No More Chances
- Termination date: At least 14 days after serving
- Voiding period: None. Tenant cannot fix it.
- Requirement: Must be within 6 months of the first N5
- Next step: File the L2 immediately after the termination date.
The 6-Month Window
Your second N5 only works if it's served within 6 months of the first N5. If 7 months have passed since your first N5, your next notice resets to a "first N5" with the full 7-day voiding period. Don't wait too long.
The 7-Day Voiding Period
When you serve a first N5, the tenant gets 7 days to "void" the notice. What counts as voiding depends on the ground.
For damage: The tenant repairs the damage, or pays you the reasonable cost of repair, within 7 days. If they fix it, the N5 is dead. You cannot proceed.
For interference: The tenant stops the behaviour for 7 days. No more parties. No more harassment. If the building is quiet for those 7 days, the N5 is voided. But here's the thing: if the behaviour starts up again after the voiding period, you serve a second N5. And the second one has no voiding period.
For overcrowding: The extra occupants move out within 7 days, bringing the unit into compliance.
Half-Hearted Fixes Don't Count
If the tenant patches a wall with cardboard, or the noise stops for 3 days then resumes on day 5, the N5 is not voided. The fix has to be genuine and sustained for the full 7 days. Document everything during this window.
How to Serve the N5
Service method matters because it affects your termination date calculation.
- Hand delivery: Give it directly to the tenant. The termination date starts counting from that day. This is the best method. No ambiguity.
- Mailbox or mail slot: Drop it in their mailbox or slide it under the door. Add 5 days to your termination date.
- Regular mail: Mail it to the tenant's address. Add 5 days to the termination date.
Always use hand delivery if you can. It's faster, and it eliminates the "I never got it" defence at the hearing. If you hand-deliver, bring a witness or take a photo of the moment. Fill out a Certificate of Service immediately.
Certificate of Service
Fill this out the same day you serve. It records who you served, how, when, and where. You'll need it at the LTB hearing. Without it, you may not be able to prove service.
Evidence You Need
The LTB won't take your word for it. You need documentation. The more organized your evidence, the faster the Adjudicator rules in your favour.
For Damage Claims
- Photos with timestamps. Use your phone's camera. Make sure the date and time are visible in the photo metadata. Take wide shots and close-ups.
- Two written repair estimates from licensed contractors. Not verbal quotes. Written, on letterhead, with the contractor's name and contact info.
- Move-in photos showing the condition of the unit before the tenant caused the damage. This is why you always photograph the unit at move-in.
For Interference Claims
- A noise/incident log. Date, time, duration, what happened, who was affected. "March 14, 2026, 1:30 AM to 3:45 AM, loud music and yelling from Unit 4, tenant in Unit 3 called me to complain."
- Written complaints from other tenants. Emails or signed letters. Get them dated.
- Police reports if police were called. The incident number alone is useful.
- Your own communications. Emails or texts where you asked the tenant to stop the behaviour. Shows you gave them a chance.
For Overcrowding
- Municipal bylaw determination confirming the unit's maximum occupancy.
- Evidence of the actual number of occupants. This is harder. Utility usage spikes, complaints from other tenants, your own observations during legal inspections.
Damage Claims: The Repair Estimate Rule
If you're serving the N5 for damage and you want the LTB to order the tenant to pay for repairs, get at least two written repair estimates before you serve the N5.
Why two? Because the LTB wants to see that you got a fair price. One estimate looks like you picked the most expensive contractor. Two estimates show you did your homework.
Don't do the repairs before the hearingunless it's a safety emergency (like a broken window in January or water damage that's causing mold). If you repair everything before the hearing, the Adjudicator might reduce your claim because they can't see the damage themselves. Bring the photos, bring the estimates, and let the LTB decide.
If you hadto repair for safety reasons, keep every receipt and invoice. Take before-and-after photos. Explain to the Adjudicator why you couldn't wait.
What Happens After the N5 Expires
The termination date has passed. The tenant didn't void the notice. They didn't move out. Now what?
File an L2 application with the Landlord and Tenant Board. The L2 is the "Application to End a Tenancy and Evict a Tenant." The filing fee is $201.
Attach your N5, your Certificate of Service, and all your evidence. The more complete your application, the smoother the hearing goes.
Current wait time for an L2 hearing: 6 to 9 months. Yes, that long. The LTB backlog is brutal. This is why your evidence needs to be rock-solid. You don't want to wait 8 months only to lose because your photos didn't have timestamps.
Keep Documenting After You File
The 6 to 9 month wait means the tenant is still in the unit. If they continue the behaviour, log every incident. You can present ongoing evidence at the hearing. It shows the problem didn't stop, which makes it harder for the Adjudicator to give relief.
Common Mistakes
Serving an N5 for a one-time incident
A single loud party or one noise complaint is almost never "substantial interference." The LTB wants to see a pattern. Serve the N5 after the third or fourth documented incident, not the first.
Wrong termination date math
First N5 needs at least 20 days. Second N5 needs at least 14 days. If you serve by mail or mailbox, add 5 days on top. Getting this wrong invalidates the notice entirely.
Serving a second N5 after the 6-month window
Your second N5 must be served within 6 months of the first. If you miss this window, the next N5 resets to a first N5 with a full voiding period. Calendar it.
No repair estimates for damage claims
Showing up to the LTB and saying "the damage will cost $3,000 to fix" without written estimates will get your claim reduced or denied. Get two quotes on paper.
Completing repairs before the hearing
Unless it's a safety emergency, don't fix the damage before the LTB sees it (through your photos and estimates). Repairing early can weaken your claim for costs.
