N5 Notice in Ontario: Damage, Interference & Overcrowding
The N5 is the notice you serve when a tenant damages the property, interferes with other people's reasonable enjoyment, or overcrowds the unit. Unlike an N4, the first N5 is voidable — the tenant gets a chance to fix the problem and stop the eviction in its tracks. Misunderstand that, and your notice falls apart at the LTB.
The N5 — officially the "Notice to End your Tenancy for Interfering with Others, Damage or Overcrowding" — is the Landlord and Tenant Board (LTB) form Ontario landlords use for behaviour problems that fall short of the most serious conduct. It covers three distinct grounds: undue damage, substantial interference with reasonable enjoyment, and overcrowding above legal limits.
What sets the N5 apart from the N4 is the second chance built into it. The first N5 you serve in a 12-month period is voidable. The tenant has 7 days to correct the behaviour, stop the conduct, or repair or pay for the damage. If they do, the notice is void and the tenancy continues as if nothing happened. That is the law working as intended, not a loophole.
This guide covers the three N5 grounds, exactly how the 7-day void period works, why a second N5 within 6 months is different, the 20-day termination rule, when you can finally file with the Board, how to escalate to an L2 application, and the mistakes that quietly void an N5 before you ever get to a hearing.
When you can serve an N5
You can serve an N5 once the damage, interference, or overcrowding has actually happened and you can describe it with specific dates and facts. There is no waiting period before serving, but the notice must set out what the tenant did, when, and why it is a problem. A vague N5 that just alleges "noise" or "damage" with no details is the easiest kind to lose.
The Three Grounds for an N5
An N5 can only be used for one or more of three specific grounds. If your complaint does not fit one of these, the N5 is the wrong form — and using the wrong form is fatal at the LTB. Each ground has to be described on the notice with enough detail that the tenant knows exactly what they are accused of and how to fix it.
Damage to the rental unit or property
The tenant, an occupant, or a guest has wilfully or negligently caused undue damage to the rental unit or the residential complex. This is more than ordinary wear and tear. Think a hole punched in drywall, a broken door, ruined flooring, or appliances damaged through neglect. The N5 must describe the damage and the dates it happened.
Interference with reasonable enjoyment
The conduct of the tenant, an occupant, or a guest has substantially interfered with the reasonable enjoyment of the unit or complex for the landlord or other tenants, or with another lawful right, privilege, or interest of the landlord. Excessive noise, harassment of neighbours, garbage left in common areas, or threatening behaviour can fall here.
Overcrowding
The number of people occupying the rental unit on a continuing basis exceeds what is permitted by health, safety, or housing standards. This ground is narrow and tied to actual standards, not the landlord's preference. The N5 must set out the facts that show the unit is over the legal occupancy limit.
For each ground, the N5 must include the details of what happened: a plain description of the conduct or damage, and the dates it occurred. "The tenant is a problem" is not enough. "On April 3 and April 11 the tenant played amplified music after midnight, prompting written complaints from two neighbouring units" is the level of specificity the Board expects.
The First N5 Is Voidable: The 7-Day Rule
This is the heart of how an N5 works, and the part landlords most often get wrong. The first N5 you serve in a 12-month period gives the tenant 7 days to make things right. The clock starts the day after the notice is served.
Void period
7 days
The first N5 gives the tenant 7 days from service to correct the problem and void the notice
Termination date
20 days
The termination date on the N5 must be at least 20 days after the notice is given
Second N5 window
6 months
A second N5 served within 6 months of the first is not voidable
Escalation
L2
If the tenant does not void the notice, you file an L2 application with the LTB
How the tenant voids the notice depends on the ground. For interference or overcrowding, the tenant voids the N5 by stopping the conduct — the behaviour has to actually cease within the 7 days. For damage, the tenant voids it by repairing the damage, paying you the reasonable cost of repair, or paying the reasonable cost of replacement within the 7 days. If they do any of that, the N5 is void and you cannot proceed on it.
You cannot file until the void period passes
Even though the termination date is 20 days out, the 7-day correction period controls when you can act. You cannot file an application with the LTB based on a first N5 until the 7 days have passed and the tenant has not corrected the problem. File during the void period and the application is premature — expect it to be dismissed.
The Second N5 Within 6 Months Is Not Voidable
The second chance only happens once per cycle. If the tenant voids the first N5 by fixing the problem, but then engages in the same kind of conduct again within 6 months, you can serve a second N5 — and this one is not voidable. There is no 7-day correction period the second time.
With a non-voidable second N5, the termination date must still be at least 20 days after the notice is given, but the tenant has no statutory opportunity to stop the eviction by correcting the behaviour. You can apply to the LTB to end the tenancy after serving it, because there is no void period to wait out. This is the mechanism that stops a tenant from voiding notice after notice while the same problem repeats.
The second N5 only works if it is served within 6 months of the first and the conduct is similar in nature. Document everything from the first incident onward — without a clear record tying the second problem to the first, you lose the advantage of the non-voidable notice and may be back to square one.
The 20-Day Termination Date Rule
Separate from the void period, every N5 has to set a termination date that is at least 20 days after the notice is given to the tenant. This is the date the tenancy would end if the matter is not resolved and the LTB later orders eviction. Getting this date wrong is one of the most common ways an N5 fails.
Counting the days
The day you give the notice does not count as day one — you count forward from the day after service. If you serve by mail or courier, the RTA adds extra days for deemed delivery on top of the 20, pushing the termination date later. A termination date that is even one day too early voids the notice, while a date that is slightly too late does not. When in doubt, add a cushion.
Note that the 20-day termination date and the 7-day void period are two different clocks running at the same time. The 7 days govern when the tenant can fix the problem and when you can file; the 20 days govern the earliest the tenancy could actually end. Do not collapse them into a single number.
Escalating to an L2 Application
If the void period passes without the tenant correcting the problem (first N5), or you have served a non-voidable second N5, the next step is to file an L2 application(Application to End a Tenancy and Evict a Tenant) with the LTB. The N5 by itself never evicts anyone — it only sets up the application.
1. Confirm the void period has passed
For a first N5, you cannot file until the 7-day correction period has ended and the tenant has not fixed the problem. For a non-voidable second N5, you can file after serving it. Filing too early gets the application dismissed.
2. File the L2 with the LTB
Submit the L2 through the LTB's online portal (or another accepted method), attach the N5 and your Certificate of Service, and pay the application fee. The facts on the L2 must match what you described on the N5 — you cannot raise new incidents that were not on the notice.
3. Attend the hearing
The LTB schedules a hearing. Bring the lease, the N5, the Certificate of Service, and your evidence: photos of damage, repair estimates, written complaints, dated logs, or witness statements. The burden is on you to prove the conduct described on the notice actually happened.
4. Enforce through the Sheriff
If you win, the LTB issues an eviction order. You cannot change the locks yourself. You file the order with the Court Enforcement Office (the Sheriff), who carries out the physical eviction. Self-help evictions are illegal in Ontario.
The N5 alone never evicts anyone
No matter how serious the conduct, the notice by itself has no enforcement power. Only an LTB eviction order, enforced by the Sheriff, ends a tenancy against the tenant's will. At the hearing, the LTB can also refuse eviction or give the tenant conditions to follow instead of ending the tenancy.
N5 vs N4 vs N7: Which Notice Fits
Choosing the wrong notice is one of the fastest ways to lose. The three forms cover very different problems, and they are not interchangeable.
N4 — non-payment of rent. Used only when rent is unpaid. It is about money, not behaviour, and is voidable by paying the full amount owing before the termination date.
N5 — damage, interference, or overcrowding. Used for conduct that is a problem but not the most serious. The first N5 is voidable with a 7-day correction period; the termination date is at least 20 days out.
N7 — serious problems. Used for the most serious situations, such as serious impairment of safety, wilful and significant damage, or illegal acts. The N7 carries a much shorter notice period and is generally not voidable. If the conduct is severe, the N5 may be the wrong, too-lenient form.
The practical rule: use the N4 for money, the N5 for ordinary behaviour and damage problems, and the N7 only for genuinely serious or dangerous conduct. If you are unsure whether a situation is "serious" enough for an N7, the N5 is usually the safer starting point because it gives the tenant a documented chance to correct.
Common Mistakes That Void an N5
Most failed N5 cases trace back to a short list of avoidable errors. Check yourself against every one of these before serving:
- Vague details with no specific dates or facts about what the tenant actually did
- Setting a termination date less than 20 days after the notice is given
- Filing the L2 before the 7-day void period on a first N5 has passed
- Treating a first N5 as non-voidable and skipping the tenant's chance to correct
- Serving a second N5 more than 6 months after the first, or for unrelated conduct
- Using an N5 for non-payment of rent (that is an N4) or for serious conduct (that may be an N7)
- Raising new incidents at the L2 hearing that were never described on the N5
- Serving by a method the RTA does not permit, or failing to keep proof of service
