Ontario LTB Notice Guide · Reviewed September 2026
Current-form reminder: LTB forms and procedures changed during 2026. Use this overview to understand the pathways, then confirm the current form, instructions, service rules and filing method with Tribunals Ontario.
Ontario landlords and tenants encounter several prescribed Landlord and Tenant Board notices. The form number matters because each notice is designed for a particular situation and has its own grounds, timing and procedural requirements.
A termination notice is not the same as an eviction order. If a tenant does not leave voluntarily, a landlord generally needs to follow the applicable Landlord and Tenant Board process and obtain an order before an eviction can be legally enforced.
N4 — Non-Payment of Rent
The N4 is used when rent is owing. For notices given on or after September 21, 2026, the minimum termination period is generally 7 days. OHI tracks the related reforms in its Ontario Rental Rule Changes for 2026 overview. The notice can become void if the tenant pays the amount required under the applicable rules before the deadline. Accuracy in the rent calculation and service date is important.
N5 — Interference, Damage or Overcrowding
An N5 can apply to certain allegations involving substantial interference, damage or overcrowding. Some N5 situations include an opportunity to correct the conduct within a specified period, while repeat situations can operate differently.
N6 — Illegal Acts or RGI Income Issues
The N6 addresses specific statutory grounds involving alleged illegal acts and certain misrepresentation of income in rent-geared-to-income housing. It is not interchangeable with the N5 or N7, and the current official instructions should be checked before acting.
N7 — Serious Problems
The N7 is reserved for particular serious allegations identified by the Residential Tenancies Act and LTB form instructions. It should not be treated as a general-purpose notice for ordinary tenancy disputes.
N8 — Ending a Tenancy at the End of the Term
The N8 can apply to specified circumstances such as certain persistent late-payment situations and other grounds set out in the legislation. Its termination-date requirements differ from notices that can end a tenancy earlier.
N12 — Landlord, Purchaser or Family Use
An N12 may be used in qualifying circumstances when the landlord, purchaser or specified family member genuinely requires the rental unit for residential occupation. Notice timing, compensation and good-faith requirements are important, and purchaser-use rules have additional statutory conditions.
Read the N12 and selling-a-tenanted-property guide.
N13 — Renovation, Demolition or Conversion
An N13 is used for specified demolition, conversion or repair/renovation situations. The required notice period is generally longer than many other notices, and compensation or a tenant’s right of first refusal can arise depending on the circumstances.
What About N11?
An N11 is different because it records a mutual agreement between landlord and tenant to end a tenancy. It is not a unilateral eviction notice. Both parties should understand the agreement before signing it.
Tenant Notices: N9 and N15
N9 is a tenant notice to end a tenancy and has its own termination-date requirements. N15 is a separate tenant pathway for qualifying fear of sexual or domestic violence and abuse and uses specific supporting documentation. These are not landlord eviction notices.
