Landlord arrears notices and accurate rent accounting

Before serving an N4, reconcile the rent account and confirm that each amount belongs in a nonpayment-of-rent notice. A demand that mixes rent with unrelated charges can create problems. Use the current form and calculate the termination date using the applicable service rules.

For notices given on or after September 21, 2026, the minimum notice period is seven days. That period does not authorize a lockout or eliminate the need for the proper LTB process. Record later payments accurately and assess whether the notice has been voided by payment. If an application proceeds, prepare the lease, complete ledger, service evidence, and required updates. Careful accounting helps avoid a hearing dominated by preventable calculation disputes.

Check the opening balance and each rental period before entering figures on the notice. A missed credit, returned transfer, or payment from an assistance program can change the amount claimed. Keep supporting bank and receipt records, and separate charges whose recovery requires a different legal basis. Use the correct tenant names and unit information. The notice should describe the actual account rather than a rounded estimate or an amount increased to encourage the tenant to negotiate.

After service, keep the account current and review the effect of every payment before taking another procedural step. A tenant's payment may change the status of the notice or the amount that can be pursued. If a hearing is required, prepare a concise explanation of disputed entries and retain the earlier versions of the ledger. Consider a realistic repayment arrangement where appropriate, using the required process and documents. Good arrears management combines lawful notices, reliable accounting, and a clear understanding of what the LTB is being asked to order.
