Ontario Rent Increase Guideline 2026 — 2.5% and What It Means

The Ontario Rent Increase Guideline for 2026 is 2.5%, set by the Ontario Ministry of Municipal Affairs and Housing and applicable to most residential tenancies subject to the Residential Tenancies Act (RTA). Landlords can raise rent by up to 2.5% per 12-month tenancy period with 90 days' written notice using Landlord and Tenant Board (LTB) Form N1, provided the unit is rent-controlled and the tenancy started before November 15, 2018.

This guideline shapes every Ontario rental relationship — from a 1-bedroom condo in CityPlace to a 4-bedroom semi-detached in Leslieville, a basement apartment in Mississauga, or a heritage Victorian in Cabbagetown. Below is the complete 2026 landlord and tenant playbook on the 2.5% guideline, exemptions, above-guideline applications, and proper notice procedures.

What the 2.5% guideline actually covers

The 2.5% Ontario Rent Increase Guideline for 2026 applies to most residential rental units occupied before November 15, 2018, including apartments, condos, basement apartments, secondary suites, mobile-home pads, and care-home accommodation. The increase is capped at 2.5% per 12-month period — landlords cannot stack two years' worth into a single jump.

The guideline is set annually by the Ontario government based on the Consumer Price Index (CPI) for Ontario, calculated from June-to-June year-over-year inflation. The 2026 guideline of 2.5% reflects Ontario CPI for the relevant measurement period and is statutorily capped at 2.5% maximum under the 2019 RTA amendments — meaning even if CPI were 5%, the guideline cannot exceed 2.5%.

Units exempt from the guideline

The biggest exemption is new construction. Units first occupied for residential use after November 15, 2018 are exempt from the guideline indefinitely. Landlords of these units can raise rent by any amount with proper notice and tenant consent (typically through new annual rent on lease renewal). This includes most new builds in CityPlace condos delivered after 2019, the Daniels Waterfront, and recent purpose-built rental towers in North York, Mississauga, and Vaughan.

Other exemptions include co-operative housing, social/subsidized housing under separate rules, university and college residences, hospitals and long-term care facilities, and short-term rentals (under 28 days, governed by separate municipal bylaws).

How a landlord properly serves a rent increase

A valid rent increase under the 2026 guideline requires three things: 90 days' written notice on LTB Form N1 (Notice of Rent Increase), at least 12 months since the last increase or the start of tenancy, and the increase amount cannot exceed 2.5%.

Form N1 must include the current rent, the new rent, the date the increase takes effect, and the landlord's signature. The notice must be delivered in person, by mail (allowing 5 days for delivery), by email if the tenant has consented in writing to email notice, or by leaving in the tenant's mailbox if the lease permits.

Example calculation

Current rent: $2,400/month. 2026 guideline: 2.5%. Maximum new rent: $2,460/month ($2,400 × 1.025 = $2,460). Notice required by April 1, 2026 for an effective date of July 1, 2026. If the landlord serves notice on May 15, the earliest valid effective date is August 15, 2026.

What the tenant can do

If served a proper N1 at or below the 2.5% cap, the tenant must either accept the increase or terminate the tenancy with 60 days' notice under Form N9. The tenant cannot refuse a guideline-compliant increase. If the N1 exceeds the guideline (above-guideline increase), the tenant can challenge at the LTB and the increase is held in abeyance until the LTB rules.

Above-guideline increases (AGI) — when landlords can charge more

Landlords can apply for an above-guideline rent increase (AGI) for specific reasons under Section 126 of the RTA: capital expenditures (major repairs, building improvements), extraordinary increases in operating costs, or extraordinary increases in security or utility services. AGI applications go to the LTB for review and tenant input.

Capital expenditure AGIs

Capital expenditures must be major work that benefits tenants — new roof, elevator replacement, balcony repairs, mechanical system overhauls. The LTB calculates an annual amortized portion and adds it to permissible rent over a period of years. Typical capital AGI awards in 2024-2025 ranged from 0.8% to 2.4% above guideline annually for 3-5 years.

Extraordinary cost AGIs

Operating cost AGIs are rare and require demonstrated extraordinary increases — typically more than the CPI inflation rate plus 50%. Insurance and municipal tax spikes can occasionally qualify, but most operating cost increases (utilities, routine maintenance) do not.

Tenants can challenge AGI applications by filing a response with the LTB within the timeline specified in the application package, typically 30 days. The LTB holds a hearing where both parties present evidence. AGI decisions are appealable to the Ontario Divisional Court.

What happens if the landlord violates the guideline

If a landlord charges rent above the legal maximum (either by serving an invalid N1 or simply demanding higher rent), the tenant has multiple remedies under the RTA. The tenant can apply to the LTB for an order finding the rent illegal and ordering repayment of overpayments under Section 135. There is no statutory limit on how far back overpayments can be recovered if the tenancy is ongoing.

Common violations include:

• Raising rent more often than every 12 months
• Raising rent above 2.5% without an approved AGI
• Failing to provide 90 days' written notice on Form N1
• Charging "additional fees" not provided in the lease — parking, storage, utilities not separately metered, etc.
• Raising rent during a fixed-term lease before the renewal anniversary

Landlords who repeatedly violate the guideline can face fines under the RTA's offences provisions and may have future rent increases held invalid. FSRA-licensed mortgage brokers advising landlord clients on portfolio acquisitions routinely check rent rolls for unenforceable illegal rent and adjust purchase price accordingly.

How the guideline interacts with vacancy decontrol

Ontario operates a vacancy-decontrol system. When a tenant moves out and a new tenancy begins, the landlord can set the new rent at any level — there is no cap on the starting rent for a new tenant. This is the single most important nuance of the Ontario system and explains why long-term tenants in 1990s-built apartments in the Annex, Junction, Mississauga, and Ottawa often pay $800-$1,400 less than market rent for identical units.

Vacancy decontrol creates the underlying pressure on landlord-tenant relationships. Long-term tenants paying significantly below-market rent have strong incentive to stay; landlords have strong incentive to encourage turnover (legally via cash-for-keys or end-of-tenancy notices, sometimes illegally via renoviction or harassment). LTB enforcement against bad-faith N12/N13 notices increased substantially in 2024-2025, with awards up to 12 months' rent plus differential damages for displaced tenants.

Frequently asked questions

What is the Ontario Rent Increase Guideline for 2026?

The 2026 guideline is 2.5%, set by the Ontario Ministry of Municipal Affairs and Housing. This is the maximum percentage by which a landlord can increase rent in any 12-month period for rent-controlled units (typically those first occupied before November 15, 2018). Landlords must provide 90 days' written notice using LTB Form N1. Units occupied after November 15, 2018 are exempt from the guideline.

Does the 2.5% apply to my new condo built in 2022?No. Residential units first occupied for rental purposes after November 15, 2018 are permanently exempt from the Ontario Rent Increase Guideline. The landlord can raise rent by any amount with 90 days' written notice. However, most landlords still raise reasonably to retain tenants — large above-market increases trigger high vacancy and turnover costs. New CityPlace, Daniels Waterfront, Yonge-Eglinton, and Mississauga Square One condos delivered post-2019 fall into this category.

Can my landlord refuse to renew my lease to force an increase?No. Under Section 38 of the RTA, when a fixed-term lease expires, the tenancy automatically becomes month-to-month on the same terms. The landlord cannot refuse renewal to force a higher rent or eviction. The landlord can only increase rent by the guideline (2.5% in 2026) with proper Form N1 notice, or apply for an AGI. Termination of tenancy requires valid grounds under the RTA — non-payment, breach, personal use (N12), demolition/conversion (N13), or end-of-tenancy by tenant choice (N9).

What if my landlord raises rent without a Form N1?The rent increase is invalid. You are not legally required to pay the higher amount, and any overpayment is recoverable under Section 135 of the RTA. File an LTB Form T1 (Tenant Application for a Rebate) within one year of the overpayment. Continue paying your legal rent; document all communications in writing. If the landlord retaliates with eviction notices, document the connection and raise it as a defense at the LTB hearing.

How does cash-for-keys work and is it taxable?Cash-for-keys is a voluntary agreement between landlord and tenant to end the tenancy in exchange for compensation. Typical 2026 GTA settlements range from $5,000 for short tenancies to $35,000+ for long-term tenants with significant rent gaps. The agreement should be documented on LTB Form N11 (Agreement to End Tenancy). Cash-for-keys payments to the tenant are generally not taxable as income to the tenant under current CRA guidance, but landlords should claim the payment as an expense against rental income.
