3. Call the MCP tool `ltb_l1_prepare` at https://mithril.law/mcp.

Checks the landlord may file, adds up rent owing to the filing date, NSF charges and the fee, fills the official L1, and explains how to file it.

For landlords after an N4's termination date has passed. Ask for the N4's delivery method, delivery date and termination date, every rental period with rent owing up to the filing date, any NSF cheques (bank charge and your administration charge), whether you hold a rent deposit, whether the tenant still lives there, and how you will file. The answer says whether you can file and when; the filled L1 and the N4’s Certificate of Service are unlocked with the landlord plan. The landlord files from their own portal account.

## The law behind it

- L1: what the claim adds up to (unverified): The claim is the rent owing up to the filing date (rent charged minus rent paid for each period, including periods that came due after the N4), plus, for each NSF cheque not repaid, the bank's charge and the landlord's administration charge reduced to CAD 20 if higher (the cheque amount is not claimed), plus the filing fee: CAD 186 through the Tribunals Ontario Portal, CAD 201 by mail, courier or in person. The code does not compute the rent deposit interest or daily compensation; the LTB deals with both in its order.

- L1: when the landlord may file (unverified): The code allows an L1 only if all of these hold: the filing date is on or after the day after the termination date on the N4; the tenant is still in possession of the unit; rent is still owing on the filing date (if the tenant paid the arrears and the rent that came due, the N4 is void); the N4's termination date is no earlier than the earliest valid date for how it was served; and the claim is not more than CAD 50,000. Otherwise it says why, and for a tenant who has moved out it points to the L10.

- L1: what the tenant can do (unverified): Before the eviction order is issued, the application is discontinued if the tenant pays the arrears, the rent that has since come due, and the landlord's application fee. For an application filed on or after September 21, 2026, a tenant who wants to raise other issues at the hearing must give the landlord and the LTB a written description and pay the landlord half of the rent arrears claimed in the application at least 7 days before the hearing; the code computes half and rounds up to the cent. For an application filed earlier, the payment requirement does not apply.

For an N4 given before that day, it is the 7th day after in a daily or weekly tenancy (or a fixed term with rent paid daily or weekly) and the 14th day after otherwise. The day of giving is not counted and the last day is. The date is not moved off a weekend or holiday. The landlord can file an L1 from the day after the termination date on the notice (the day after the earliest date, if none is given), and there is no 30-day limit to file.

- When a notice counts as given (unverified): The code takes the day a notice counts as given from how it was delivered. Handed to the person or to an apparently adult person in the unit, left in the mailbox or where mail is usually delivered, slid under the door or through the mail slot, faxed, or emailed: the same day. Mailed by Canada Post (including registered mail) or sent by Xpresspost: the fifth day after mailing; the code never uses an earlier delivery date. Given to a courier: the next day, or if that day is a holiday, the next day that is not. For the courier rule the code treats as holidays every Saturday and Sunday, the holidays in s. 88 of the Legislation Act, 2006 with its substitution rules, the Civic Holiday, September 30, and the next weekday after any of these that falls on a weekend; a longer list can only make the date later. Email is refused unless the person agreed in writing to email service.
