Ontario Form L4: Breach of a Settlement or LTB Order
Plain-English instructions: when to use this form, how to fill it in, important deadlines and what happens next.
Form L4 is used only when a tenant breaches a specified condition of a qualifying earlier LTB-mediated settlement or order that expressly permits an L4 application. The landlord generally must apply within 30 days of that breach. It is free when filed through the Tribunals Ontario Portal.
Use this guide to fill out the official form. You still need to send it to the Landlord and Tenant Board.
Before you start, check the old order
Locate the original mediated settlement or order. It must contain a condition the tenant had to meet and a clause allowing an L4 application if that condition is not met. L4 is not the first form to use for an ordinary late rent payment where no such LTB order exists.
Complete the L4 application and declaration
- Rental address and parties: match the previous LTB file.
- Previous file: enter the file number, date of the settlement or order and the specific condition relied on.
- Reason: identify the breached condition; only seek extra rent arrears or damages if the previous L1/L2 claim and order allow that remedy.
- Declaration: describe the payment or action required, the due date, what actually happened, payments received, and why this breaches the settlement/order. Sign it.
- Attachments: include the L4, a copy of the earlier settlement/order and the signed declaration.
An LTB consent order says a tenant must pay $200 on November 1, 2026, and expressly allows L4 on default. The tenant does not pay. A landlord relying on that breach generally has 30 days from the breach to file L4, with the order and evidence of missed payment. A later payment or ambiguous condition may change the analysis.
What follows filing?
The LTB can act on the documented breach; the tenant may have rights to challenge an order and seek relief where legally available. Do not treat an L4 application as an immediate authorization to evict someone without the required enforceable order.
Common mistake to avoid
The original settlement or order must actually authorize this L4 process. A new complaint or informal payment arrangement is not enough.
