After handling hundreds of LTB files for Ontario landlords, certain mistakes come up over and over again. They are not complex errors — they are predictable, avoidable, and consistently expensive. Here are the three that cost landlords the most time and money.
Mistake 1: Waiting Too Long to Serve the Notice
Most landlords wait weeks or even months before serving an N4 after rent goes unpaid. Every month you wait is a month added to the arrears and a month added to the total timeline. The RTA allows you to serve an N4 the day after rent is due. Waiting is not kindness — it is lost money.
Mistake 2: Getting the Notice Wrong and Not Knowing It
Incorrect termination dates, overstated rent amounts, wrong service methods, and outdated form versions are the most common notice errors. These mistakes only surface at the LTB — by then you have already waited months for a hearing. The fix is simple: have a professional prepare and serve the notice from the start.
Mistake 3: Accepting Partial Payments Without Understanding the Consequences
Accepting partial rent payments after serving an N4 does not automatically void the notice — but it does change the amount you can claim in the L1 application. If you accept a payment and then file using the pre-payment amount, your application will be flagged. Always update the claimed amount to reflect what was actually received.
The Common Thread
All three mistakes have the same root: acting without understanding the rules. The LTB process is rule-bound and procedural. A landlord who does not know the rules is at a structural disadvantage against a tenant who does — or who has someone in their corner who does.
What Good Practice Looks Like
Serve the notice on the first day you are eligible. Use the current form and get the dates right. Document every interaction. Do not accept partial payments without adjusting your records. And at the first sign that the situation is escalating, call a licensed paralegal.
