What an N5 covers
Form N5, Notice to End your Tenancy for Interfering with Others, Damage or Overcrowding, can be given when the tenant, a guest or another occupant of the unit:
- substantially interferes with the reasonable enjoyment of the building by the landlord or other tenants, or with another lawful right, privilege or interest of the landlord or another tenant — persistent noise, harassment of neighbours, repeatedly blocking lawful entry, a pet's behaviour;
- wilfully or negligently causes undue damage to the unit or the building; or
- lives with more people than health, safety or housing standards allow, usually set by municipal by-laws.
The LTB updated the N5 form on September 21, 2026; older versions won't be accepted after November 30, 2026.
The first N5: 20 days, with a chance to correct
The termination date on a first N5 must be at least 20 days after the tenant receives it. The tenant then has 7 days from receipt to void the notice:
| Ground | How the tenant voids the notice within 7 days |
|---|---|
| Interference | Stop the conduct described in the notice |
| Damage | Repair the damage or pay the reasonable repair cost — or replace the item or pay to replace it, if repair isn't reasonable |
| Overcrowding | Reduce the number of occupants to the permitted limit |
If the tenant complies, the notice is void and you can't apply on it. If they don't, you can file an L2 application once the 7-day period has passed, and no later than 30 days after the termination date.
The second N5: 14 days, no second chance
If the first N5 was voided and, within six months of it, the tenant again does something that's grounds for a notice, you can serve a second N5. Its termination date need only be 14 days out, the tenant can't void it, and you can file your L2 straight away.
| First N5 | Second N5 (within six months) | |
|---|---|---|
| Minimum notice | 20 days | 14 days |
| Can the tenant void it? | Yes, within 7 days | No |
| When you can file the L2 | After the 7-day correction period | Immediately |
The details decide the case
A vague N5 — "ongoing noise complaints" — is a weak N5. The tenant has to know exactly what to stop or fix, and the LTB will look for that detail. For each incident, set out:
- the date and approximate time;
- what happened and who was involved;
- how it affected other tenants or the landlord;
- for damage, what was damaged and the reasonable cost to repair or replace it.
Back it up with evidence you can produce at a hearing: incident logs, written complaints from neighbours, photos, contractor quotes and any police or fire reports. Neighbours who were affected may need to testify.
Step by step
- Document first — Build the incident log before you serve; a notice based on one bad night rarely succeeds.
- Serve the first N5 — Current form, every incident detailed, at least 20 days to termination; keep proof of service.
- Watch the 7 days — Note whether the conduct stopped, the damage was paid for, or occupants moved out.
- File or wait — If not voided, file an L2. If voided, keep logging: the six-month window has started.
- Second N5 if it recurs — 14 days, no correction period, file immediately.
- Prepare for the hearing — Witnesses, logs and photos organized by date.
Typical N5 situations
- Late-night noise in a concrete apartment block or a wood-frame plex, logged by neighbours over several weeks.
- Smoking or cannabis odour drifting into other units, where it substantially interferes with neighbours.
- Blocking access for repairs or pest control after valid written notices.
- Negligent damage — an overflowing tub left running that floods the unit below.
- An undisclosed extra household in a one-bedroom, beyond what the municipal occupancy standard allows.
Mistakes to avoid
- Serving an N5 for ordinary wear and tear, which isn't undue damage.
- Combining unrelated grounds in one notice without clear detail for each.
- Calculating the 7-day correction period from the date you mailed the notice, instead of the date it's considered received.
- Serving a second N5 more than six months after the first, or after a first N5 that was never voided.
- Letting the L2 deadline pass — 30 days after the termination date.
After you serve
Whether the first N5 is voided or not, keep logging. If the tenant corrects the problem, the six-month window for a second N5 runs from the first notice, and your records are what show a pattern. If the behaviour stops for good, that's the outcome you wanted — the notice did its job without a hearing.
When an N7 fits better
For serious situations, Form N7 gives 10 days' notice and can't be voided. It applies where someone wilfully causes undue damage, uses the unit in a way inconsistent with residential use that causes or could cause serious damage, or seriously impairs another person's safety — and to substantial interference in a building of three or fewer units where the landlord also lives. Wilful damage must be proved as deliberate; if you aren't sure you can prove it, the LTB suggests using an N5 instead.
At the hearing
Even when the grounds are proved, the LTB must consider whether to refuse or delay the eviction. A common outcome is a conditional order — the tenancy continues if the tenant meets set conditions, and a breach lets you apply for eviction without a new hearing. Since September 21, 2026, delaying an eviction without the landlord's consent requires that the delay not be unfair to the landlord or other tenants and that there be compelling reasons.
Why it matters in apartment buildings
In a multi-unit building, one disruptive tenancy affects everyone else — and other tenants can bring their own applications if a landlord ignores the problem. Acting on complaints quickly and on paper protects the building. It's a core part of how we run apartment buildings and multi-unit properties. Our guides to the LTB process and entry rules cover the related steps.
General information, not legal advice. Each N5 depends on its facts; consider advice before serving a notice that may end in a hearing.
