The N4 Notice to End a Tenancy Early for Non-Payment of Rent is the mandatory starting point for most rent arrears cases before the Landlord and Tenant Board. It is one of the most commonly used notices in Ontario and also one of the most frequently challenged. The N4 does not evict a tenant. It is a formal notice that rent is overdue and that the tenancy may be terminated if the tenant does not either pay what is owed by the termination date or move out. Because the N4 is the foundation document for an L1 eviction application, defects in the N4 often lead to dismissal or delay later in the process. For landlords dealing with rent arrears, Ontario law requires specific steps before an eviction application can proceed, and understanding these requirements is essential for a successful outcome.
A valid N4 must clearly identify the rent owing and the time period it covers. In general, the notice should include only amounts that qualify as “rent” under the tenancy arrangement. Landlords should be careful about adding charges that may not be considered rent (for example, penalties, interest, or unrelated costs), because including non-rent amounts can create problems at the hearing. The safest practice is to maintain a clear rent ledger showing: the due date for each rental period, the rent charged, the payments received (with dates), and the running balance. If the tenant has made partial payments, the landlord should record exactly how those payments were applied, because the LTB will often expect a transparent calculation showing how the arrears were reached.
Timing is one of the most common sources of N4 disputes. The required notice period depends on how rentis paid. For most monthly tenancies, the termination date on the N4 must beat least 14 days after the tenantis given the notice. For daily or weekly tenancies, the notice period is shorter (typically 7 days). The day the notice is given is generally not counted as day one; landlords should calculate carefully to avoid an “off-by-one” error. Getting the dates right on an Ontario N4 notice is critical — even a one-day miscalculation can result in the LTB dismissing the application entirely.
Importantly, the N4 is void if the tenant pays the rent arrears by the termination date. If payment is made in full within the allowed timeframe, the tenancy continues as if the notice had never been served (the landlord cannot proceed on that N4). If rent is not paid in full, the landlord may apply to the LTB after the termination date, but the tenant still has the right to remain in the unit unless and until the LTB issues an eviction order and the Sheriff enforces it. Accurate record-keeping is one of the most important steps when pursuing rent arrears in Ontario, because adjudicators expect clear documentation at every LTB hearing.
Because non-payment applications are procedural, landlords should pay close attention to service and record-keeping. The LTB Rules of Procedure set out acceptable service methods(for example, handing the notice to the tenant, placing it in a mailbox, or leaving it at the unit in a permitted way), and landlords should keep proof of service for the hearing (such as a completed Certificate of Service and any supporting notes). After the termination date, a landlord will usually file an L1 if the tenant is still in possession and rent remains unpaid. If the tenant has already moved out, a landlord may consider an L9 to seek a monetary order for rent owing without seeking eviction. Many cases also resolve through payment arrangements, mediation, or consent orders. For Brampton landlords, understanding what the N4 can and cannot do—and getting the dates, amounts, and service method right—can reduce the risk of dismissal and avoid unnecessary delay. If you are a Brampton landlord struggling with rent arrears, Ontario’s legal framework provides effective remedies — but only when proper procedures are followed correctly from the start.
