The Ontario government has officially released the 2027 rent increase guideline, setting the maximum annual increase for most rent-controlled residential units at 1.9%. While this represents a slight decrease from the 2.1% guideline in 2026, it remains an important update for landlords and real estate investors planning their rental strategy for the year ahead.
Whether you own a single investment property or manage a growing portfolio, understanding how Ontario's rent increase rules work is essential for remaining compliant with the Residential Tenancies Act while effectively planning your property's long-term financial performance.
What is the Rent Increase Guideline?
Each year, the Province of Ontario establishes a rent increase guideline based on the Ontario Consumer Price Index (CPI). This guideline sets the maximum amount that landlords can increase rent without applying for approval from the Landlord and Tenant Board (LTB).
For 2027, the guideline has been set at:
✔ 1.9%
This is a decrease from:
- 2026: 2.1%
- 2025: 2.5%
The annual guideline is intended to balance increasing operating costs for landlords while helping protect tenants from significant year-over-year rent increases. Under Ontario legislation, the annual guideline is also capped at 2.5%, even if inflation exceeds that amount.
Does the Guideline Apply to Every Rental Property?
One of the most common misconceptions is that every rental property in Ontario is subject to the annual guideline.
In reality, the guideline applies to most residential rental units first occupied before November 15, 2018. Rental units first occupied after November 15, 2018 are generally exempt from provincial rent control, meaning landlords are not limited to the annual guideline when increasing rent.
However, even exempt properties must still comply with Ontario's rental legislation. Landlords are still required to:
- Provide tenants with at least 90 days' written notice
- Use the appropriate Landlord and Tenant Board notice form
- Increase rent no more than once every 12 months
These requirements remain in place regardless of whether a property is exempt from rent control.
Planning Ahead as a Landlord
For landlords with rent-controlled properties, the annual guideline plays an important role in budgeting and forecasting rental income.
Although a 1.9% increase may appear modest, it can help offset rising operating expenses such as:
- Property taxes
- Insurance premiums
- Utility costs
- Building maintenance and repairs
- Property management expenses
- General inflation
Understanding how much rental income can legally increase each year allows investors to make informed financial decisions while remaining compliant with provincial legislation.
Before Increasing Rent
Before serving a rent increase notice, landlords should confirm:
- The property is subject to Ontario's rent increase guideline.
- At least 12 months have passed since the last rent increase (or since the tenancy began).
- The increase does not exceed the allowable amount, unless approved by the Landlord and Tenant Board.
- The tenant receives the required 90 days' written notice using the correct LTB form.
Following these steps helps ensure the increase is legally enforceable and reduces the risk of unnecessary disputes.
What This Means for Investors
Ontario's rental market continues to evolve, making it increasingly important for investors to stay informed about legislative updates. Understanding how annual rent increase guidelines affect cash flow, budgeting, and long-term investment performance can help landlords make more confident and strategic decisions.
Whether you're purchasing your first rental property or expanding an existing portfolio, knowing which properties are rent-controlled—and how Ontario's rental legislation applies—is an important part of evaluating investment opportunities.
As always, when questions arise regarding unique tenancy situations or above-guideline increases, investors should consult the appropriate legislation or seek advice from a qualified legal or property management professional.
