LTB N5: Notice to End your Tenancy for Interfering with Others, Damage or Overcrowding
For substantial interference, damage, or overcrowding. A first N5 gives the tenant 7 days to correct the problem and void the notice.
What the N5 is
The N5 covers three grounds: the tenant (or their guest) is substantially interfering with the reasonable enjoyment of other tenants or the landlord, has caused undue damage, or is overcrowding the unit beyond health and safety standards.
A first N5 has a termination date at least 20 days out, and the tenant can void it by correcting the behaviour, repairing/paying for damage, or reducing occupancy within 7 days. If the problem recurs within 6 months, a second N5 can be served with a 14-day termination date — and the second notice cannot be voided. The landlord must then file an L2 application to actually end the tenancy.
How to fill it out
- Choose the reason(s) — interference, damage, or overcrowding — and tick every box that applies.
- Details of the events: this is the heart of the N5. For each incident give the date, approximate time, and specific facts (“loud party until 3:00 a.m. on June 12; police attended”), not conclusions (“tenant is a nuisance”). Vague details are the most common reason N5s are thrown out.
- Termination date: at least 20 days out for a first notice; 14 days for a second notice served within 6 months of the first.
- For damage, state the repair cost or what must be repaired to void the notice.
- Sign, serve, and keep proof of service. Diarize the 7-day voiding window — if the tenant corrects the problem in time, the notice is void; if not (or if it recurs), an L2 application follows.
