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 your Tenancy for Interfering with Others, Damage or Overcrowding. It is for tenant behaviour that goes beyond not paying rent. It covers three grounds, and you tick the ones that apply 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 health, safety or housing standards allow. A law or by-law sets the limit, and the form asks you to identify it.

You can't just say "too many people." The form asks how many people you believe live in the unit and which law or by-law you used to work out the maximum. Your local municipal by-law office can tell you which applies, and anything they give you in writing is useful 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 put right in time: The notice is void. You cannot apply to evict on it.
  • If not put right: You can apply to the LTB for an eviction order once the 7 days have passed.

Second N5

No More Chances

  • Termination date: At least 14 days after serving
  • Voiding period: None. Tenant cannot fix it.
  • Requirement: A first N5 was given, and the conduct happened more than 7 days but less than 6 months after it
  • Next step: You can apply to the LTB for an eviction order straight away.

The 6-Month Window

A second N5 is only allowed if you gave a first one and the conduct it describes happened more than 7 days, but less than 6 months, after you gave the first. If the conduct comes after the 6 months, your next notice is treated as a first N5, with the full 7-day period to put things right. Don't wait too long.

The 7-Day Voiding Period

When you serve a first N5, the tenant gets 7 days after receiving it to "void" the notice by putting things right. What that means depends on the ground.

For damage: The tenant can repair the damaged property, pay you your estimate of the repair cost, replace it if repair is not reasonable, pay your estimate of the replacement cost, or make arrangements you accept to do either. If they do, you cannot apply to evict them on that notice.

For interference: The tenant has to stop the activities or correct the behaviour you described within 7 days of receiving the notice. If they do, the first N5 is voided. If the behaviour starts again later, you may be able to give a second N5, which has no voiding period. The rules for that are above.

For overcrowding: The tenant reduces the number of people living in the unit to the number you stated within 7 days of receiving the notice.

If You Think the Fix Falls Short

The form says the tenant does not have to move out if they correct the problem within 7 days, and it sets no standard beyond that. If you think a repair or a change in behaviour does not really fix it, document it with photos and dates during the 7 days. That is the argument you would put to the LTB, not a rule on the form.

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. It counts as given the day you leave it there, so no days are added.
  • 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: Get Your Numbers Ready

If you're serving the N5 for damage, a first N5 asks for your estimate of what it will cost to repair or replace the damaged property. Written estimates or invoices make that number easier to explain and defend.

Photos with dates, and the quotes you got, show the LTB where the number came from.

Don't do the repairs before the hearing unless 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, photos and invoices are what you have to show what was damaged. Bring them and let the LTB decide.

If you had to 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 Notice

On a first N5 the 7 days have passed and the tenant has not put things right. Or you gave a second N5. 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 LTB lists the fee as $201, or $186 through the Tribunals Ontario Portal.

Attach your N5, your Certificate of Service, and all your evidence. The more complete your application, the smoother the hearing goes.

The tenant does not have to move out because they received the notice. The LTB schedules a hearing where you have to prove the claims in the notice and the application, so your evidence needs to be solid. See how long an eviction takes.

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 rarely "substantial interference." Keep the date, time and facts of each event, and give notice when the pattern is clear.

Wrong termination date math

First N5 needs at least 20 days. Second N5 needs at least 14 days. If you serve by mail, add 5 days on top. Getting this wrong invalidates the notice entirely.

Serving a second N5 after the 6-month window

The conduct in a second N5 must come more than 7 days but less than 6 months after the first. If it comes later, the next N5 is treated as a first N5 with a full voiding period. Calendar it.

No repair estimates for damage claims

A first N5 asks for your estimate of the cost to repair or replace. Written estimates or invoices show where the number came from.

Completing repairs before the hearing

Unless it's a safety emergency, take dated photos and keep estimates before you repair, so you can show the LTB what was damaged.

Frequently Asked Questions

Substantial interference means ongoing conduct that seriously disrupts other tenants or the landlord. A single loud party is not enough. You need a pattern: repeated noise complaints, harassment of neighbours, blocking common areas, illegal activity in the unit, or persistent conduct that makes other tenants unable to enjoy their homes. The key word is "substantial." Minor annoyances don't qualify.
Yes, if the pet noise rises to "substantial interference." A dog that barks for 10 minutes when the mail arrives is not grounds. A dog that barks for hours every day while the tenant is at work, and you have multiple written complaints from other tenants? That qualifies. Document every complaint with dates, times, and the names of the tenants affected.
On a first N5 the tenant can put damage right by repairing the property, paying your estimate of the repair cost, replacing it if repair is not reasonable, paying your estimate of the replacement cost, or making arrangements you accept to do either. If they do that within 7 days of receiving the notice, you cannot apply to evict them on that notice. If you think a repair falls short, keep photos and dates. That is the argument you would put to the LTB, and the form sets no standard beyond it.
Yes. They are separate notices on separate grounds. The N4 covers unpaid rent and the N5 covers interference, damage or overcrowding, so if a tenant is doing both you can give both.
The form sets no limit. The rule that matters is the first and second one. A second N5 cannot be voided, and it is only allowed if you gave a first N5 at least 7 days earlier and the conduct in the second happened more than 7 days but less than 6 months after it. If it has been more than 6 months since your last N5 to this tenant, the next one is a first N5 again.
Document everything. If they escalate the behaviour, damage more property or threaten you, call the police first if you feel unsafe and file a report. A police report can be evidence at the LTB, and anything new belongs in the details of a later notice.
The timelines and procedure, no; the form itself, yes. The N5 was replaced on September 21, 2026, and the previous version is rejected as of November 30, 2026, but the process is unchanged: 20 days for the first N5 with a 7-day voiding period, 14 days for the second N5 with no voiding period. The big Bill 60 change is to the N4 termination period, which dropped from 14 days to 7 for any N4 served on or after September 21, 2026. An N4 served before that date needed 14 days for a monthly tenancy, or 7 for a weekly or daily one.
Yes. On a first N5 you state what you estimate it will cost to repair or replace the damaged property. If you go to an LTB hearing you can ask for an order that the tenant pay the cost. Bring written estimates or invoices and photos. If you already completed emergency repairs (like fixing a broken window in winter), bring the receipts and invoices. The LTB decides what is reasonable.
