Official form boundary. This helper creates a preparation summary only. It does not replace a current LTB notice, application, service rule, hearing direction, order, lawyer, or licensed paralegal.

Methodology and assumptions

Total rent owing equals listed rent charges minus listed payments or credits.
For regular mail, the checker adds the LTB brochure's five-day deemed-service period; for courier or another method, users must enter the deemed received date confirmed from the current LTB service rule.
For deemed received dates before September 21, 2026, the estimated termination date adds 14 calendar days for most monthly or longer tenancies and 7 calendar days for daily or weekly tenancies.
For deemed received dates on or after September 21, 2026, the estimated termination date uses 7 calendar days for every tenancy period.
The preparation sheet keeps the official N4 separate and points users to the current LTB form and instructions.

Important limitations

Does not include non-rent charges unless they are legally rent for the tenancy.
Does not determine whether a service method, email consent, courier holiday calculation, or deemed received date is legally valid.
Does not decide whether the notice is voided by later payment or whether an L1 can be filed.
