Can an Ontario landlord charge a late fee for rent?
Short answer: No. Section 134 of the Residential Tenancies Act says a landlord can't collect a fee, penalty or other like amount from a tenant, and a late fee is a penalty. A late fee clause in the lease is void (s. 4), and a tenant who paid one can ask the LTB to order it repaid. What you can do: charge back your bank's NSF fee for a bounced cheque plus an administration charge of up to $20, offer a discount of up to 2% for paying on time, and use the N4 or N8 when rent is unpaid or keeps coming late.
What the law allows and what it doesn't
| Charge | Allowed? | Where it comes from |
|---|---|---|
| Flat late fee (for example $50 if rent is late) | No | RTA s. 134(1)(a): no fee, premium, penalty or other like amount |
| Daily late charge or interest on late rent | No | Same section; it is still a penalty |
| The fee your bank charges you for a bounced (NSF) cheque or payment | Yes | O. Reg. 516/06, s. 17, para. 4 |
| Your own administration charge for an NSF cheque | Yes, up to $20 | O. Reg. 516/06, s. 17, para. 5 |
| A discount of up to 2% for paying on or before the due date | Yes, if agreed with the tenant | RTA s. 111(2), O. Reg. 516/06, s. 10 |
| Extra keys the tenant asks for, or lost keys | Yes, at your direct cost only | O. Reg. 516/06, s. 17, paras. 1 and 2 |
| A refundable key or fob deposit | Yes, up to the expected replacement cost | O. Reg. 516/06, s. 17, para. 3 |
The ban applies "whether or not the money is refundable", and it also covers a superintendent or property manager acting for you (s. 134(2)). Putting the fee in the lease doesn't help: section 4 makes any lease term that is inconsistent with the Act void.
What happens if you charge one anyway
- The tenant can get it back. The LTB's T1 application lists "illegal charge" as a reason and gives fees, bonuses, commissions and penalties as examples. The LTB can order you to repay it (s. 135).
- The window is one year. The LTB can't order repayment on an application filed more than one year after the money was collected (s. 135(4)). So a $50 late fee you took on Tuesday, November 10, 2026 can be claimed back until about November 10, 2027.
- It can muddy an LTB case. If the tenant falls behind and you file an L1, the claim is rent and NSF charges only. A ledger that mixes in late fees makes your numbers harder to prove, and your N4 must list rent only.
A worked example
Rent is $1,800, due on the 1st. The lease says "$50 fee if rent is late."
- November rent arrives late. The tenant pays $1,800 on Tuesday, November 10, 2026. You can't add the $50. If you take $1,850, the extra $50 is an illegal charge the tenant can claim back.
- December's cheque bounces. Say your bank charges you $45 for the returned cheque (use your bank's actual fee). You can ask the tenant for $45 plus an administration charge of up to $20, so up to $65 on top of the $1,800 rent that is still owed. Keep the bank's notice as proof.
- What to do about the lateness itself. Unpaid rent is an N4. Rent paid more than 7 days late at least 3 times in 6 months is persistent late payment and an N8. Neither costs you a late fee clause.
Where the toolkit helps: Instead of a late fee, the toolkit's rent and expense tracker records the date every payment arrives, and its Persistent Late Payment Checker flags rent received more than 7 days late, so an N4 or N8 rests on records, not a lease clause. See what is inside the $19 toolkit
The legal way to reward on-time rent: a prompt payment discount
Instead of punishing late rent, you can reward on-time rent. Section 111(2) of the Act lets you give a discount of up to 2% for paying on or before the due date without lowering your lawful rent. The only condition in the regulation is that the discount is part of a written or oral agreement (O. Reg. 516/06, s. 10), so put it in writing.
With $1,800 rent, 2% is $36. The tenant pays $1,764 if rent arrives on or before the 1st, and $1,800 otherwise. Your lawful rent stays $1,800, so future guideline increases are worked out from $1,800. A discount above 2% for on-time payment does change the lawful rent calculation (O. Reg. 516/06, s. 12(3)), so stay at 2% or less.
Mistakes to avoid
- Copying a late fee clause from a US or older template into an Ontario lease.
- Calling a late fee something else ("admin fee", "processing fee"). The Act bans the fee, not the name.
- Charging the $20 NSF administration charge when nothing bounced. It applies to an NSF cheque, not to a payment that was simply late.
- Requiring post-dated cheques or automatic payments. You can't make either a condition of the lease (s. 108). You can accept them if the tenant offers.
- Keeping poor records. Write down the date each payment arrived and what you applied it to; that is your evidence for an N4, an N8 or an L1.
Need receipts for every payment? Tenants can ask for one free of charge (s. 109), and our free Ontario rent receipt covers it.
