Looking for the current guideline? See our post on Ontario's 2027 rent increase guideline.
In the ever-evolving landscape of Ontario's housing market, staying informed about the rules governing residential rent increases is crucial for both landlords and tenants. The Residential Tenancies Act (RTA) in Ontario meticulously outlines the regulations for rent adjustments, including the timing, permissible increase rates, and the process for disputing increases deemed unreasonable. This guide aims to equip you with essential knowledge about your rights and responsibilities, ensuring a harmonious landlord-tenant relationship.
The short version.
Ontario law mandates that landlords may only raise rent once every 12 months. Additionally, the increase rate is capped at a guideline percentage established by the province. For 2026, this guideline is set at 2.1%, and the province has set the 2027 guideline at 1.9% for increases taking effect between 2027-01-01 and 2027-12-31. For example, if your lease began on 2025-06-01 at $1,000 monthly, the maximum increase allowable would be to $1,021 per month starting 2026-06-01. Landlords are required to provide written notice of this increase at least 90 days before its implementation.
It's important to note that landlords are prohibited from imposing new fees or raising existing fees for amenities initially included in the rent (such as parking or laundry services). Exceptions to this rule exist only if the tenant requests alterations to the lease agreement or in the event of unforeseen cost escalations beyond the landlord’s control, such as significant utility rate hikes.
While the rent increase guideline applies broadly to most private residential rentals under the RTA, certain exceptions exist. Notably, some units are exempt from the guideline entirely, including most units in buildings, additions, and basement apartments first occupied for residential purposes after November 15, 2018. Separately, landlords of guideline-covered units may apply to the Landlord and Tenant Board (LTB) for an above-guideline increase (AGI) for specific reasons, such as eligible major capital work or extraordinary increases in municipal taxes. For a detailed exploration of these exceptions, the Government of Ontario provides a helpful resource guide.
The RTA offers tenants safeguards against unjustified rent increases. Should you suspect your rent was raised unfairly, you have the right to contest the hike by filing an application with the LTB (generally within one year of the increase taking effect). The LTB's review can result in either upholding the increase or ordering a rent reduction to the former amount, with potential refunds for any overpayments made.
Despite a successful dispute, landlords retain the right to apply for future increases once per annum, adhering to RTA stipulations. This ongoing cycle underscores the importance of understanding both the legal framework and the procedural nuances of contesting rent adjustments.
