N5 (damage, interference, overcrowding)
For damage, disturbing others, or too many occupants — usually with a chance to fix it.
General information, not legal advice. Ontario rules and timelines change — always confirm the current forms and requirements with the Landlord and Tenant Board or a licensed paralegal before acting.
When to use it
An N5 covers undue damage, substantially interfering with others' reasonable enjoyment, or too many people in the unit.
The "void" period
A first N5 gives the tenant 7 days to correct the problem (stop the behaviour or repair/pay for damage). If they fix it in time, the notice is void. A second N5 within six months does not give a chance to correct.
