A rent collection and arrears ladder

Missed rent isn't a single event, it's the start of a ladder with fixed rungs — a notice period, a filing fee, a hearing format, an enforcement step — and skipping one doesn't speed the process up, it usually restarts it.

Key takeaways

  • • The N4 notice period is 14 days under the current rule. A Bill 60 proposal would drop it to 7 days for all tenancy types, but it is not in force — no commencement date has been proclaimed, and none should be printed.
  • • An L1 application costs $201, or $186 filed through the Tribunals Ontario Portal.
  • • Last month's rent deposit interest is tied to the same rent-increase guideline percentage published each year — 2.1% for 2026, 2.5% for 2025 — and misapplying that deposit mid-tenancy is one of the most common landlord errors on this ladder.
  • • Ontario's process runs through the LTB; British Columbia's runs on materially different deposit and notice rules under its own Residential Tenancies Act — the two are not interchangeable.

STEP 01 OF 10

Day rent is due: send an informal reminder, not yet a legal notice

A same-day message noting the payment hasn't arrived is not a legal step and doesn't need to follow any statutory form — it's a courtesy that resolves a genuine number of cases before the ladder needs to escalate at all. Keep it in writing, though; it becomes the first entry in the documentation trail this whole ladder depends on.

Use the same channel every time, and keep the tone identical for every tenant. Consistency here matters for the same reason screening consistency matters under OHRC Regulation 290/98 — a documented, uniform process protects the landlord if a decision is ever questioned.

STEP 02 OF 10

Day 2-3: send a formal written notice of arrears

This documents the exact amount owed and the date it was due, distinct from the N4 that follows. It's not itself a notice to end the tenancy — it's the record that shows the arrears were communicated clearly before the legal notice period started.

Keep a copy with a timestamp. If the case eventually reaches a hearing, a clear paper trail showing the tenant was informed promptly carries real weight.

STEP 03 OF 10

Serve the N4 once arrears are confirmed

The N4 (Notice to End a Tenancy Early for Non-payment of Rent) currently carries a 14-day notice period. A provision in Bill 60 would replace RTA s.59(1) with a flat 7-day period for all tenancy types, but it is not in force: commencement is by order of the Lieutenant Governor in Council, and no such order has been made. Until that order is made, 14 days remains the operative period and no commencement date for the shorter one has been set — a “21 September 2026” date circulates widely but rests on no primary source.

The 14-day period gives the tenant the right to void the notice by paying the full amount owed before it expires. Track that clock precisely; a notice served with an error in the amount or the date can be challenged on that basis alone.

STEP 04 OF 10

Track the clock and the tenant's right to void the notice

If full payment arrives before the 14 days expire, the N4 is void and the ladder resets to step one for any future arrears — it doesn't carry forward as evidence of a "pattern" in a legal sense, even though it's worth keeping on file for your own records.

Document the exact day the notice period expires, not an approximate date. The L1 application in the next step depends on being able to state precisely when the tenant's right to void ended.

A partial payment during the 14 days doesn't automatically void the notice the way full payment does. Note the exact amount received and the date, since it changes the arrears figure carried into the next step without resetting the clock.

STEP 05 OF 10

File the L1 application if the arrears remain unpaid

The L1 (Application to Evict a Tenant for Non-payment of Rent) costs $201, or $186 through the Tribunals Ontario Portal (tribunalsontario.ca/ltb/forms-filing-and-fees). The LTB assigns a file number and a hearing date once it's filed.

File promptly once the N4's 14 days have expired without payment. Delay here doesn't protect either party — it just extends the period arrears continue to accrue.

LTB fees are stated as non-refundable, so double-check the arrears figure and the served N4's details before filing rather than after — an error caught pre-filing costs nothing; one caught after does.

STEP 06 OF 10

Serve the application and Notice of Hearing on the tenant

Service has to be done correctly to avoid delays or a challenge to the outcome later. If you're not confident in the service requirements, this is the point in the ladder most worth a lawyer's five minutes rather than a guess.

Keep proof of service on file with a date and method — the same discipline as every earlier step. A challenge to service is one of the more common ways a case gets delayed at hearing.

STEP 07 OF 10

Prepare for the hearing format that fits the case

A straightforward, uncontested non-payment case typically proceeds as a summary hearing; a contested case — where the tenant disputes the amount, alleges a repair issue, or raises a human-rights ground — takes longer and needs more preparation. Know which type you're walking into before the hearing date arrives, not on the day itself.

Bring the documentation trail from steps 2-5: the informal reminder, the formal notice, the served N4, and the arrears calculation. A hearing rewards a clear paper record far more than it rewards a confident verbal account.

The hearing may run in person, by videoconference, or in writing, depending on the case. Confirm the format in advance so you're not preparing for the wrong kind of proceeding.

STEP 08 OF 10

Run the deposit-interest duty in parallel, not as part of the arrears case

If the tenancy carries a last month's rent deposit, the landlord separately owes annual interest on it "calculated using a rate tied to the guideline the province sets" — specifically, the same percentage as that year's rent-increase guideline (treadstonelaw.ca). The guideline was 2.1% for 2026 and 2.5% for 2025 (ontario.ca/page/rent-increase-guideline).

This duty is unrelated to whether the tenant is in arrears — it runs every year regardless. It belongs on this ladder because the most common related error is applying that deposit to mid-tenancy arrears without the tenant's written agreement, when the RTA reserves it for the final rental period only.

STEP 09 OF 10

If an order issues and the tenant doesn't comply, escalate to the Court Enforcement Office

Once the LTB issues an order, enforcement of an eviction runs through the Sheriff, not the landlord directly. The Sheriff "schedules and carries out the actual physical enforcement of the eviction according to their own process and scheduling" (treadstonelaw.ca) — the landlord files the order and then works within the Sheriff's own timeline, not a self-set one.

Do not attempt a self-help eviction while waiting for the Sheriff's process. It undermines the legal position built through every prior step of this ladder.

STEP 10 OF 10

Close the file and reconcile

Document what was recovered, what wasn't, and any amount written off, and keep the full ladder's paper trail on file. The documentation habit built for this case becomes the template for the next one — and if the corporation ever needs to demonstrate a consistent, non-discriminatory process across multiple arrears cases, this file is the evidence.

Note anything about the case that should change the process going forward — a service method that caused a delay, a notice that was challenged on a technicality. Feed that back into how the next case on this ladder is run, rather than repeating an avoidable mistake.

Common mistakes

Applying the last month's rent deposit to mid-tenancy arrears without written agreement. The deposit is reserved for the final rental period only. Applying it earlier without the tenant's written consent is itself a compliance error layered on top of the arrears issue.

Screening a re-tenanting applicant on income alone. OHRC Regulation 290/98 requires income information to be considered together with rental history and credit references, not on its own — it is illegal to apply a rent-to-income cutoff such as 30%. That rule attaches to every landlord decision on this ladder, not just the arrears case itself.

Skipping the written notice-of-arrears step before serving the N4. A tenant who never received clear, dated notice of the amount owed has a stronger basis to challenge the N4 at hearing. The informal and formal notice steps exist to close that gap.

Assuming a Bill 60 proposal to shorten the N4 period is already in force. It is not proclaimed, and no commencement date exists. Serving a 7-day N4 on the assumption the shorter period already applies is a defect that can invalidate the notice entirely — use 14 days until a real commencement date is published.

The deposit-interest math, worked

Scenario. A tenant's last month's rent deposit is $1,800. For 2026, the rent-increase guideline is 2.1%, so the annual interest owed is $1,800 × 0.021 = $37.80. For 2025, the guideline was 2.5%, so the same deposit would have earned $1,800 × 0.025 = $45.00 that year. The rate moves annually with the published guideline — a landlord using a flat, memorized percentage from a previous year will misstate the amount owed, even with the deposit figure itself unchanged.

Where the process differs materially in British Columbia

  • Deposit cap: BC caps a security deposit at half a month's rent (RTA s.19(1)); Ontario has no equivalent security-deposit cap, only the last-month's-rent deposit mechanic.
  • Deposit return: BC requires return (with interest) or a dispute-resolution application within 15 days of the later of the tenancy ending and the landlord receiving a forwarding address (RTA s.38(1)).
  • Rent-increase notice: BC requires at least 3 months' notice of a rent increase (RTA s.42(2)) and no increase within the first 12 months of a tenancy (s.42(1)); Ontario requires 90 days' notice with no equivalent 12-month bar, tied to the published guideline. BC's actual increase percentage is set by regulation, not stated in the Act itself — do not assume it matches Ontario's guideline number.
  • • The two processes run under entirely separate statutes with separate tribunals — do not carry an Ontario LTB step into a BC case, or the reverse.

Frequently asked

Can a landlord apply the last month's rent deposit to unpaid rent mid-tenancy?

Not without the tenant's written agreement. The deposit is reserved for the final rental period only, and applying it earlier unilaterally is a separate compliance problem layered on top of the arrears itself.

Does the N4 notice period change if the tenant pays part of what's owed?

A partial payment doesn't automatically void the notice the way full payment does — but it changes the arrears figure the L1 application should reflect. Recalculate before filing rather than using the original N4 amount.

What happens if the tenant vacates before the hearing?

The arrears portion of the claim can generally still proceed for the money owed, even though the eviction question becomes moot. Keep the documentation trail regardless of how the tenancy itself ends.

Is this process different for a commercial tenant?

Yes, entirely. The LTB has residential jurisdiction under the Residential Tenancies Act only; commercial leasing sits under the Commercial Tenancies Act and common law, with no LTB involvement at all. Do not run a commercial arrears case through this ladder.

Does the deposit-interest obligation still apply if the tenant is currently in arrears?

Yes — it's a separate, unrelated duty that runs annually regardless of the tenant's payment status. Track and pay it on schedule even mid-arrears-case; withholding it isn't a lawful response to unpaid rent.
