Late Rent in Ontario: What a Landlord Can and Cannot Do
When rent is late in Ontario, the instinct to add a late fee or change the locks is understandable, and both are illegal. Here is what you actually can charge (almost nothing), the correct N4-to-LTB process, and why self-help eviction can cost you up to $100,000.

Rent is late. The instinct is to add a late fee, maybe threaten the locks. In Ontario, both of those instincts are wrong, and the second one is an offence that can cost you up to $100,000. Here is what the law actually lets a landlord do, and the process that works.
You cannot charge a late fee or interest
This surprises many landlords: in Ontario, you cannot charge a late fee, a penalty, or interest on late rent. A lease clause that imposes a late fee is void, even if the tenant signed it.
The one and only charge tied to a failed payment is for a returned (NSF) payment: you may recover the actual charge your bank levied for the returned cheque, plus an administration charge capped at a maximum of $20 per cheque. That is the ceiling, set by regulation.
One important detail landlords get wrong: NSF and admin charges are not rent. They should not be included in the arrears figure on an N4 notice, and doing so can actually invalidate the notice. Keep them separate.
(For the record, interest runs the other way on the last month's rent deposit: the landlord must pay the tenant annual interest on that deposit. That is a landlord obligation, not something you can charge a tenant.)
The correct process: N4, then L1
For non-payment, Ontario has one path, and it runs through the Landlord and Tenant Board:
- Serve an N4 (Notice to End your Tenancy Early for Non-payment of Rent). For an N4 given on or after September 21, 2026, the termination date must be at least 7 days after the notice is given, for every tenancy.
- If the tenant does not pay or void the notice by the termination date, apply to the LTB on Form L1 to evict for non-payment and collect the arrears. The filing fee is $186 through the Tribunals Ontario Portal.
- The LTB decides. If it orders eviction, only the Court Enforcement Office (the Sheriff) can enforce it. Not you.
What changed: Bill 60 shortened the N4 period for monthly and yearly tenancies from 14 days to 7, in force for notices given on or after September 21, 2026 (Ontario OIC 618/2026). An N4 given before that date used the 14-day period for monthly and yearly tenancies, and 7 days for daily and weekly ones. See the N4's move to 7 days, and our N4 form guide for the full rules.
Never take matters into your own hands
This is the part that turns a rent problem into a legal one for the landlord. In Ontario you cannot, to force a tenant out:
- Change the locks.
- Remove the tenant's belongings.
- Shut off vital services (heat, water, electricity, gas).
Doing any of these is an illegal eviction, an offence under the Residential Tenancies Act investigated by the province's Rental Housing Enforcement Unit. As of July 1, 2026, the maximum fines are up to $100,000 for an individual and $500,000 for a corporation. A tenant who is locked out can apply to the LTB (Form T2) and call the enforcement unit. Eviction happens only through the LTB and the Sheriff, full stop.
The tenant can usually pay to stay
Landlords should know this going in, because it shapes the strategy: a tenant can stop the process by paying.
- An N4 is voided if the tenant pays all the rent owing, plus any rent that has since come due, before you file the L1 application. That can be after the notice's termination date, so a late-but-pre-application payment still cancels the N4.
- After an LTB eviction order, the tenant can still stop it by paying the full amount the order specifies before the Sheriff enforces it, which voids the order through the process set out in the Act. Treat it as a defined process, not something that happens automatically.
A separate situation is the tenant who keeps paying late even though they eventually pay: that is addressed through a different route, an N8 notice and an L2 application for persistent late payment, not the N4 process. Rent is late as soon as it is unpaid after its due date, but for an N8 the test is stricter: since September 21, 2026, failing to pay rent within seven days of its due date on three occasions within six consecutive months counts as persistent late payment, whether the rent was paid late or is still unpaid (a payment that only looks late because the landlord applied it to older arrears does not count), and the Board can still find persistent lateness in other circumstances; our N8 guide has the details. Either way, the fastest route to actually getting paid is usually a workable agreement, not a drawn-out hearing.
What actually works
- Communicate early and in writing. A missed payment is often a cash-flow blip, not a pattern.
- Use the official process if it continues: N4, then L1, then let the Board and Sheriff do the enforcement.
- Consider a payment agreement. Where you and the tenant make a repayment plan under section 206 of the Act, the LTB's official Payment Agreement Form is required, so use it for that plan.
- Keep clean records of rent received, dates, and communications, because your L1 application will need them.
Frequently asked questions
Can I charge a late fee for late rent in Ontario? No. Late fees, penalties, and interest on rent are not permitted. The only allowed charge is for a returned payment: the bank's fee plus an admin charge capped at $20 per cheque.
Can I change the locks if a tenant stops paying? No. That is an illegal eviction, an offence with fines up to $100,000 for an individual and $500,000 for a corporation. Eviction must go through the LTB and be enforced by the Sheriff.
How long is the N4 notice period? 7 days for an N4 given on or after September 21, 2026, whether rent is paid monthly, yearly, weekly or daily (Bill 60, in force by Ontario OIC 618/2026). Before that date, monthly and yearly tenancies needed 14 days.
Can the tenant cancel the eviction by paying? Usually yes. Paying all the rent owing before you file the L1 voids the N4, and paying the amount an order specifies before the Sheriff enforces it voids the order. Persistent late payment is handled separately, through the N8 and L2 process.
