Ontario's rent increase guideline for 2026 is 2.1% — down from 2.5% in 2025 and the lowest cap since 2022. Applying it correctly involves more than multiplication: the right form, 90 days' written notice, a 12-month spacing rule, and knowing whether your unit is even covered. Here's the complete 2026 guide, with the exact math and the mistakes that void increases.
The 2026 Guideline: 2.1%
The guideline is set each year by the Ontario government from the Ontario Consumer Price Index and published by the end of August for the following calendar year. For increases taking effect any time in 2026, the maximum for guideline-covered units is 2.1% — no LTB approval needed at or below that number.
| Year | Guideline | Year | Guideline |
|---|---|---|---|
| 2019 | 1.8% | 2023 | 2.5% (capped) |
| 2020 | 2.2% | 2024 | 2.5% (capped) |
| 2021 | 0% (freeze) | 2025 | 2.5% |
| 2022 | 1.2% | 2026 | 2.1% |
The math on typical Waterloo Region rents: $1,800 → maximum increase $37.80 (new rent $1,837.80); $2,200 → $46.20 ($2,246.20); $2,600 → $54.60 ($2,654.60). Small numbers — which is exactly why retention economics dominate rent-increase strategy for guideline units (more below).
Which Units the Guideline Covers — and the Big Exemption
The guideline applies to most private residential tenancies in Ontario, including houses, apartments, condo rentals and basement suites. The major exemption: units first occupied for residential use after November 15, 2018 are not subject to the guideline at all — landlords of those units may raise rent by any amount, subject to the same notice rules.
Other non-guideline situations: vacant units (rent resets to market for a new tenant — vacancy decontrol), community housing, and certain care homes. Also different: a negotiated increase for added services (e.g., parking added mid-tenancy) uses its own agreement process rather than the N1.
If you own a newer condo in Kitchener or Waterloo's recent towers, the exemption likely applies to you — but market conditions in 2026 discipline what you can actually charge, and an above-market renewal that triggers a move-out costs far more than it gains. Check the exemption date carefully: it's first residential occupancy of the unit, not your purchase date.
How to Raise Rent Legally: N1, 90 Days, 12 Months
Three requirements, all mandatory:
1. The right form. For a guideline (or exempt-unit) increase, serve LTB Form N1 (Notice of Rent Increase). Letters, texts and verbal announcements have no legal effect.
2. 90 days' written notice. The increase takes effect no earlier than 90 days after the notice is served. Serve in June for an October 1 increase, and remember deemed-service delays (add 5 days if mailing).
3. 12 months' spacing. At least 12 months since the tenant moved in or since their last increase. The increase date doesn't have to match the lease anniversary, but the spacing rule is absolute.
An increase that breaks any of these is void — and if a tenant pays a void increase, they can recover it. Getting the annual N1 cycle right across a portfolio (correct amounts, correct dates, correct service, staggered tenancies) is exactly the sort of administration a professional rent collection operation automates.
Above-Guideline Increases (AGIs): The Exception Process
Landlords can apply to the LTB (Form L5) for an increase above the guideline in three cases: extraordinary increases in municipal taxes/charges, eligible major capital expenditures (roof, structural, windows — not routine maintenance), or new/increased security services. Capital-expenditure AGIs are capped at 3% above the guideline per year, spread over up to three years if the justified amount is larger.
AGIs are slow (expect many months at the LTB), tenant-contestable, and paperwork-heavy — genuine capital documentation, not invoices stapled together. For small landlords they make sense after major envelope work on older buildings; they are never a casual top-up. Our AGI guide covers the process in detail.
2026 Strategy: The Retention Math
For guideline units, the spreadsheet is blunt: the maximum 2026 increase on a $2,200 unit is $46.20/month — $554 over a year. One month of vacancy costs $2,200, plus turnover costs, plus your time. If taking the full 2.1% costs you a good tenant, you lose. Professional practice in 2026's softer market: apply the guideline routinely but predictably, communicate it early and professionally, and pair increases with visible responsiveness on maintenance — tenants renew when the value story holds.
For exempt (post-Nov-2018) units, price renewals against live market comparables, not aspiration. The 2026 Waterloo Region market has real tenant choice; above-market renewals convert directly into vacancies, and the vacancy math is unforgiving.

Frequently Asked Questions
- What is the rent increase guideline for 2026 in Ontario?
- 2.1% — down from 2.5% in 2025 and the lowest guideline since 2022. It applies to increases taking effect during calendar 2026 for guideline-covered units, and requires no LTB approval. On a $2,200 rent the maximum increase is $46.20 per month.
- How much notice do I need to give for a rent increase in Ontario?
- At least 90 days' written notice using LTB Form N1, and at least 12 months must have passed since the tenant moved in or their last increase. Both rules apply to every unit — including units exempt from the guideline cap.
- Which Ontario rental units are exempt from the rent increase guideline?
- Units first occupied for residential use after November 15, 2018 — common among newer condo towers and purpose-built rentals. Landlords of exempt units can raise rent by any amount but must still use the N1 form, give 90 days' notice, and respect the 12-month rule.
- Can I raise rent more than 2.1% in 2026?
- Only three ways: the unit is exempt (first occupied after November 15, 2018); the unit turned over (vacancy decontrol lets you set a new market rent for a new tenant); or the LTB approves an above-guideline increase via an L5 application for major capital work, extraordinary tax increases, or security services — capped at 3% extra per year for capital items.
- What happens if I raise rent without proper notice in Ontario?
- The increase is void. A tenant who paid it can recover the excess (typically via a T1 application within one year), and collecting an illegal increase can expose you to further LTB consequences. Re-serve a proper N1 and wait out the 90 days — there's no shortcut.
