How Tenants Fight Non-Payment Claims at the LTB, and How Landlords Win
Tenants facing an unpaid rent hearing are not defenceless. Many get free help from duty counsel, and they know the common defences. Landlords who underestimate this can leave without their order. Here is what to expect and how to prepare.
Key points
- The most common defences are an error on the N4, improper service, maintenance problems and disputed payments.
- A tenant can raise maintenance issues at an unpaid rent hearing, and the Board can reduce what they owe.
- Even a small error in the amount on the N4 can sink the case.
- Accurate notices, proof of service, a clean rent ledger and good maintenance records win.
Ontario tenants facing an L1 hearing for unpaid rent have access to legal aid, tenant duty counsel and a list of established defences. Landlords who underestimate this can leave without their order, or with a conditional one that doesn’t solve the problem.
The most common tenant defences
| Defence | What the tenant argues |
|---|---|
| Wrong amount | The rent owing on the N4 is incorrect |
| Improper service | The notice wasn’t properly served, or wasn’t received |
| Maintenance | The landlord didn’t keep the unit in good repair |
| Harassment | The landlord harassed or interfered with them |
| Payment | They paid, and the landlord didn’t credit it |
The maintenance defence
Under section 82 of the Residential Tenancies Act, a tenant can raise maintenance issues at an unpaid rent hearing, even if they never filed their own application. If the Board agrees the landlord didn’t maintain the unit, it can reduce what the tenant owes. That is why a clean repair record matters.
New as of September 21, 2026: for rent applications filed on or after that date, a tenant who wants to raise other issues at the hearing must pay the landlord half of the arrears claimed at least 7 days before the hearing, and give the landlord and the Board a description of the issues at least 7 days before the hearing.

If the N4 states the wrong amount, even by a small amount, or includes charges that aren’t rent, it can be found invalid. The same goes for improper service. Tenants and their representatives look for these errors. See our guide to the N4 notice.
How landlords win
- An accurate N4, with rent only and the correct amount.
- A Certificate of Service completed when you served it.
- A clear rent ledger showing every payment.
- Records showing repairs were done promptly.
- Written communication organized by date.
Duty counsel and legal aid
Many tenants get free help from duty counsel on hearing day. If you arrive without representation, you may be facing someone who does this every day. Having your own paralegal levels the playing field.
Frequently asked questions
What defences do tenants use at an unpaid rent hearing?
Most often: the N4 amount is wrong, the notice wasn’t properly served, the unit wasn’t maintained, the landlord harassed them, or a payment wasn’t credited.
Can a tenant raise repair issues at an L1 hearing?
Yes, under section 82 of the Residential Tenancies Act. For applications filed on or after September 21, 2026, the tenant must first pay the landlord half the arrears claimed and give notice of the issues at least 7 days before the hearing.
What happens if my N4 has the wrong amount?
The notice can be found invalid, which can mean starting over with a new N4.
Do tenants get free legal help at the LTB?
Many do. Tenant duty counsel is often available on hearing day, and some tenants have legal clinic support.
What is a conditional order?
An order that lets the tenant stay if they meet conditions, such as paying the arrears on a schedule. If they don’t, the landlord can apply for an eviction order.
