Quick Answer

Ontario Rent Increase 2026 — Key Rules

  1. The Ontario rent increase guideline for 2026 is 2.1%, which is the maximum most landlords may raise rent without approval from the Landlord and Tenant Board (LTB).
  2. A landlord must give at least 90 days’ written notice using the official LTB Form N1 before any rent increase can take effect.
  3. Rent can only be increased once every 12 months for the same tenant — not once per lease renewal.
  4. Rental units first occupied for residential purposes after November 15, 2018 are generally exempt from the 2.1% cap, meaning a landlord of an exempt unit may raise rent by any amount with 90 days’ notice.
  5. If a landlord raises rent illegally — above the guideline, without proper notice, or twice in 12 months — a tenant may file a T1 application with the LTB to recover the overpayment, typically within one year of the illegal charge.

What Happened to Rent in Ontario This Year

A rent increase notice landing in your inbox or mailbox is one of those moments that can stop your day cold. You look at the number, and you are not sure if it is legal. You do not know whether the timing is right. You wonder what happens if you refuse to pay.

This year, tens of thousands of Ontario tenants received notices just like yours. The majority of those increases were lawful. Some were not. The good news is that Ontario has clear rules about how, when, and how much rent can go up — and those rules give you real power.

The 2026 Ontario rent increase guideline is 2.1%. That number defines the legal ceiling for most tenants in the province. By the time you finish this article, you will know exactly where you stand, whether the notice you received meets the legal requirements, and what to do if something is not right.

The 2026 Rent Increase Guideline Explained

Direct Answer: The Ontario rent increase guideline is the maximum percentage by which a landlord may raise rent for most residential tenants in a given year, without needing Landlord and Tenant Board approval. For 2026, that maximum is 2.1%. This figure is set annually by the Ontario government based on the provincial Consumer Price Index.

The Rent Increase Guideline (RIG) is published each year by the Ontario Ministry of Municipal Affairs and Housing. It is calculated using the Ontario Consumer Price Index (CPI) — a measure of how the cost of goods and services changed over a specific 12-month window (June 2023 to May 2024 in the case of the 2026 guideline). By statute, the guideline is capped at a maximum of 2.5%, which is why 2026’s figure of 2.1% is the lowest cap in four years.

To put 2.1% in real terms: if you pay $1,800 a month, the maximum legal increase in 2026 is $37.80, bringing your new rent to $1,837.80. At $2,200 a month, the maximum increase is $46.20.

These rules are established under the Residential Tenancies Act, 2006 (RTA) — the Ontario law that governs the rights and responsibilities of landlords and tenants across the province.

Does the Rent Increase Cap Apply to Your Unit?

Direct Answer: Not every rental unit in Ontario is subject to the 2.1% cap. Units first occupied for residential purposes after November 15, 2018 are generally exempt from the annual guideline under the More Homes, More Choice Act, 2019. Landlords of exempt units may raise rent by any amount — but they must still provide at least 90 days’ written notice using Form N1 before any increase takes effect.

This exemption was introduced to encourage the construction of new rental housing across Ontario. In practice, it means that many tenants in newer condo buildings across Toronto, Mississauga, and Brampton may not have the same percentage protection as tenants in older units.

One important nuance: the exemption is based on when the unit was first occupied for residential purposes — not when the building was registered or when your particular tenancy began. A condo tower registered in 2020 may still contain units that were first occupied before November 15, 2018, and those units may remain under the guideline. Always verify the first-occupancy date before assuming you are exempt or protected.

If there is any doubt about your unit’s status, you can ask your landlord for documentation proving the first-occupancy date. Under Ontario law, a landlord is required to be able to provide that proof if a dispute arises. You may also contact the Landlord and Tenant Board (LTB) directly to confirm whether your unit is covered.

Note that shared accommodations — where you share a kitchen or bathroom with your landlord — may not be covered by the RTA at all, and different rules may apply. If your situation is unclear, getting a legal opinion before paying or disputing an increase is a reasonable step.

How a Legal Rent Increase Actually Works — Step by Step

Direct Answer: For a rent increase to be legally valid in Ontario, a landlord must satisfy all of the following: wait at least 12 months since the last increase or the start of your tenancy, deliver a properly completed Form N1 at least 90 days before the increase takes effect, and keep the percentage within the annual guideline — or hold an LTB order permitting more. Missing any one of these requirements may render the entire increase invalid.

Each of the five steps below is a legal requirement, not a suggestion. If your landlord’s notice skipped any of them, you may have grounds to challenge the increase.

  1. 1
    Wait at least 12 months.Rent may only be raised once in any 12-month period, measured from the date of the last increase — not from a lease renewal date. If less than 12 months have passed, the new notice may be void. ⚠ If skipped: the increase may be invalid regardless of the amount.
  2. 2
    Complete Form N1 — the official notice form.Form N1 (Notice of Rent Increase) is the LTB’s official notice document. A text message, email, handwritten letter, or notice on the landlord’s own letterhead does not satisfy the statutory requirement under the RTA. ⚠ If skipped: the notice may not be legally valid, even if it was delivered on time.
  3. 3
    Deliver the notice at least 90 full calendar days before the effective date.The clock starts from the day the tenant actually receives the notice. A 60-day or 30-day notice does not meet the requirement. If you received the notice fewer than 90 days before the date the increase is meant to take effect, the timing may be defective. ⚠ If skipped: the effective date may need to be pushed forward by a full rent period.
  4. 4
    Respect the guideline — or hold an AGI order.For covered units, the increase cannot exceed 2.1% in 2026. To go higher, the landlord must apply to the LTB for an Above-Guideline Increase (AGI) — a formal application where the landlord must prove specific grounds and receive a written order before charging more. Claiming an AGI exists is not sufficient; the order must be produced. ⚠ If skipped: you are only obligated to pay up to the guideline amount, regardless of what the notice says.
  5. 5
    Update the rent deposit.If a last month’s rent deposit is held, it must be topped up proportionally to reflect the new rent amount at the same time the increase takes effect. ⚠ If skipped: the tenant may request the top-up be applied toward future rent.

What Makes a Rent Increase Illegal in Ontario

Direct Answer: A rent increase in Ontario is illegal — and a tenant is not required to pay it — when the landlord has exceeded the annual guideline without an LTB order, used an informal notice instead of Form N1, raised rent more than once in 12 months, or claimed an AGI without being able to produce the approving LTB order. In all of these situations, the correct approach is to continue paying your current lawful rent — not to withhold rent entirely.

Here are the four most common ways a rent increase crosses the line:

  • •The amount exceeds the guideline with no LTB approval. Raising rent by more than 2.1% in 2026 without a formal AGI order is not permitted for covered units. Some landlords attempt to “catch up” on years where they chose not to raise rent, suggesting they can charge more to compensate. This is not permitted under the RTA. Each year’s guideline stands independently.
  • •The notice was not on Form N1. A text message, email, or even a professional-looking letter on the landlord’s stationery does not satisfy the legal notice requirement under the RTA. Only the official LTB Form N1 qualifies. A notice that fails this test may be void regardless of how much advance warning it gave.
  • •Rent was raised twice within 12 months. If your landlord increased your rent and then issued a second notice before 12 months had passed from the first increase, the second notice may be invalid. The 12-month rule is measured from tenant to tenant, not from lease renewal to lease renewal.
  • •The landlord claims an AGI without an LTB order. An Above-Guideline Increase can only be charged after the LTB has issued a written order granting it. If your landlord claims to have an approved AGI, ask for the LTB order number. Until you see that order, you are not obligated to pay the portion above the guideline.

Your Options When a Rent Increase Doesn’t Seem Right

Direct Answer: If you believe a rent increase is illegal, continue paying your current lawful rent and take action in writing. You have the right to challenge the increase at the Landlord and Tenant Board, and to apply for a refund of any amounts already overpaid. The time limit to file a T1 application is typically one year from the date the illegal charge was first applied.

Here are the concrete steps available to you, in the order you should take them:

  1. a
    Continue paying your current legal rent — do not withhold all rent.This is the single most important thing to get right. Withholding all rent can give your landlord grounds to file an L1 application (a formal LTB application to begin eviction proceedings for non-payment). Keep paying the last rent amount that was legally established while you work through the dispute.
  2. b
    Put your challenge in writing.Contact your landlord by email or letter, explain specifically why you believe the increase is invalid — wrong form, short notice, above the guideline, no AGI order — and ask for a corrected Form N1 or a withdrawal of the notice. A paper trail is valuable if the matter proceeds to the LTB.
  3. c
    File a T1 application at the LTB.The T1 (Tenant Application for a Rebate of Money the Landlord Owes) is the formal application for recovering rent you have already overpaid. It must typically be filed within one year of the date you were first charged the illegal amount. Missing this window may forfeit your right to recover it.
  4. d
    File a T2 if your landlord retaliates.If your landlord responds to your challenge by threatening eviction or interfering with your enjoyment of your unit, a T2 application (Tenant Application — Landlord Interfered with Reasonable Enjoyment) may be available to address that behaviour separately.
  5. e
    Seek legal counsel for complex files.Community legal clinics offer free advice for tenants with lower incomes. For files that have escalated — multiple violations, an AGI hearing, or sustained landlord pressure — working with a lawyer provides a material advantage at the LTB.

Mistakes Ontario Tenants Often Make — and How to Avoid Them

Ontario tenants lose money and legal rights every year not because the law fails them, but because they did not act on time or misread the rules. Here are six mistakes worth knowing before they become your own.

  • •Paying an illegal increase without questioning it. Once you have paid a higher amount for more than a year without filing a T1 application, you may lose the right to recover the overpayment. If an increase looked wrong from day one, act within that first year.
  • •Assuming all newer condos in Toronto or Mississauga are automatically exempt. The exemption depends on when the unit was first occupied for residential purposes — not the building’s construction date or your own move-in date. Always verify before accepting that the guideline does or does not apply to you.
  • •Treating a text, email, or letter as a valid notice. Only Form N1 from the LTB satisfies the statutory notice requirement. An email telling you rent is going up — however formally written — is not a lawful rent increase notice under the RTA.
  • •Paying a claimed AGI without seeing the LTB order. You have the right to ask for the order number. Until the order is produced, you are only legally required to pay up to the guideline amount. Paying more before the order arrives can complicate any recovery application later.
  • •Withholding all rent as a protest strategy. This approach often backfires. Your landlord may file an L1 application to begin eviction proceedings for non-payment of rent. Continue paying the last valid rent amount while pursuing the dispute through proper channels.
  • •Waiting too long to file a T1. The one-year limitation period for recovering overpaid rent is strict. If you have been paying an illegal amount, calculate the window from the first month you were charged — not the most recent one — and act before time runs out.

Frequently Asked Questions

What is the Ontario rent increase guideline for 2026?

The Ontario rent increase guideline for 2026 is 2.1%. This is the maximum most landlords may raise rent for covered residential units without approval from the Landlord and Tenant Board (LTB — Ontario’s rental dispute tribunal). The figure is set annually by the Ontario government using the provincial Consumer Price Index, and is capped by statute at 2.5%. The official source is ontario.ca/page/residential-rent-increases.

My landlord gave me less than 90 days’ notice — is the rent increase still valid?

Typically, no. The Residential Tenancies Act, 2006 requires at least 90 full calendar days’ written notice using the official Form N1 before a rent increase can take effect. If your notice arrived fewer than 90 days before the stated effective date, the increase may be unenforceable for that period. You may continue paying your current rent and ask your landlord to issue a corrected Form N1 with a new compliant effective date.

My building was built after 2018. Does the rent increase guideline still apply to me?

Possibly not. Units first occupied for residential purposes after November 15, 2018 are generally exempt from the annual guideline cap under the More Homes, More Choice Act, 2019. However, the exemption depends on the unit’s first-occupancy date — not the building’s registration date. Your landlord must still provide 90 days’ written notice using Form N1 regardless of exemption status. If you are unsure, ask your landlord to provide documentation of the first-occupancy date, which they are required to produce if there is a dispute.

Can my landlord raise my rent twice in one year in Ontario?

Generally, no. The RTA permits only one rent increase per 12-month period for the same tenant. That 12-month window is measured from the date your last increase took effect — not from your lease renewal date. If you received a second notice before 12 months had passed from the first increase, the second notice may be invalid.

My landlord says they can charge an above-guideline increase for renovations — do I have to pay it?

Only if your landlord has obtained a formal LTB order approving an Above-Guideline Increase (AGI). A landlord cannot unilaterally decide they are entitled to charge more because of renovations or capital improvements — they must apply to the LTB, attend a hearing, and receive a written order before charging above the guideline. Ask your landlord for the LTB order number. Until that order is produced, you are only legally required to pay up to the 2.1% guideline amount.

I’ve already been paying an illegal rent increase for several months. Can I get that money back?

Possibly. If the increase was illegal under the RTA, you may be able to recover the overpaid amount by filing a T1 application (Tenant Application for a Rebate of Money the Landlord Owes) at the LTB, typically within one year of the date you were first charged the illegal amount. This type of file can become complex, particularly if you have been overpaying for many months or across multiple increases. A legal consultation can help you assess the value and strength of your claim.

Does a text message or email count as a legal rent increase notice in Ontario?

Generally, no. The RTA requires the landlord to provide written notice using the LTB’s official Form N1 (Notice of Rent Increase). An informal notice by text, email, or handwritten letter typically does not satisfy the statutory requirement, regardless of how much advance warning it provided. If you received only an informal notice, you may ask your landlord to serve a valid Form N1. The clock on the 90-day requirement starts from the date a valid Form N1 is received.

I’m a newcomer renting in Toronto — are the rent rules different for me?

The same RTA rules apply to all residential tenants in Ontario, regardless of immigration status, nationality, or length of time in Canada. You have the same rights as any other tenant — including the right to a valid Form N1, the 90-day notice period, and the right to challenge an illegal increase at the LTB. Many newcomers in Toronto and Scarborough also explore real estate law services for newcomers as they transition from renting to buying their first property in Ontario.

When It’s Time to Talk to a Lawyer

Most rent disputes can be handled with the right information. Knowing the 2026 guideline, recognizing an invalid Form N1 notice, and filing a T1 application at the LTB are steps many tenants can take independently, or with support from a community legal clinic.

That said, some situations are better handled with retained legal counsel: a landlord pursuing an Above-Guideline Increase at the LTB hearing stage, a file where you have been overpaying for six months or longer and need to maximize your recovery, a landlord applying sustained pressure or threatening eviction alongside the dispute, or multiple procedural violations within the same tenancy.
