Ontario Rent Increase Guideline 2027: Ontario has locked in its lowest rent increase guideline in years. The province has confirmed that the 2027 rent increase guideline is 1.9 percent, down from 2.1 percent in 2026, and the new cap applies to any rent increase that takes effect on or after January 1, 2027. For roughly 1.4 million rent-controlled households across Ontario, that number sets the ceiling on how much a landlord can legally raise rent over the next 12 months without going to the Landlord and Tenant Board. And for landlords planning ahead, the clock is already running, because Ontario requires 90 days written notice before any increase, which means the earliest a landlord can serve a Form N1 for a January 1, 2027 increase is October 3, 2026.
The timing here trips up more people than the percentage itself does. A tenant might see a notice arrive in early October and assume the higher 2026 rate of 2.1 percent applies, when in fact what matters is not the date the notice is served but the date the increase actually takes effect. A notice served in October 2026 with an effective date of January 1, 2027 or later must use the 1.9 percent figure, not the older 2.1 percent guideline still running through the rest of 2026. Getting this detail wrong is one of the most common reasons a rent increase notice ends up disputed at the Landlord and Tenant Board. We’ll be updating this article monthly as new guidance, sample calculations, and enforcement updates become available.
What Is Ontario’s Rent Increase Guideline?
The Ontario rent increase guideline is a percentage set every year by the provincial government under the Residential Tenancies Act. It represents the maximum amount most landlords can raise rent for an existing tenant in a 12 month period without applying for special approval from the Landlord and Tenant Board. The number is not arbitrary. It is tied to Ontario’s Consumer Price Index but is legally capped at 2.5 percent, meaning that even in years of high inflation, the guideline cannot legally exceed that ceiling. Here is how the guideline has moved over the past several years, showing the steady decline heading into 2027.
| Year | Rent Increase Guideline | Change From Prior Year |
|---|---|---|
| 2021 | 0% (rent freeze) | Frozen due to pandemic conditions |
| 2022 | 1.2% | First increase after the freeze |
| 2023 | 2.5% | Capped at the legal maximum |
| 2024 | 2.5% | Capped at the legal maximum |
| 2025 | 2.5% | Capped at the legal maximum |
| 2026 | 2.1% | First drop in four years |
| 2027 | 1.9% | Lowest guideline since 2022 |
The Dollar Math Behind the 1.9 Percent Guideline
Percentages on their own do not tell tenants much about their actual monthly costs, so here is what the new guideline means in real numbers across a range of common Ontario rents.
| Current Monthly Rent | Maximum 2027 Increase (1.9%) | New Monthly Rent |
|---|---|---|
| $1,200 | $22.80 | $1,222.80 |
| $1,500 | $28.50 | $1,528.50 |
| $1,800 | $34.20 | $1,834.20 |
| $2,000 | $38.00 | $2,038.00 |
| $2,500 | $47.50 | $2,547.50 |
| $3,000 | $57.00 | $3,057.00 |
This is the maximum a landlord can charge under the standard guideline. It is not a mandatory or automatic increase. Landlords can choose to raise rent by less than 1.9 percent, or not raise it at all, and many do not increase rent every single year even where the law permits it.

The N1 Notice Deadline: Why October 3, 2026 Matters
Ontario law requires landlords to give tenants at least 90 days written notice before any rent increase takes effect, using the official Form N1, Notice of Rent Increase. For a rent increase that is meant to take effect on January 1, 2027, counting back 90 days lands on October 3, 2026. That is the earliest date a landlord can legally serve a valid N1 for a January increase, and it is also the date many property managers across the Greater Toronto Area, Ottawa, and other high-rent markets are treating as the unofficial start of the 2027 rent increase season.
A few practical rules govern how the N1 process works.
- A landlord can only raise the rent once every 12 months for the same tenant in the same unit
- The 90 day notice period must be full calendar days, not business days, and the notice must specify the exact new rent amount and the exact effective date
- If the notice is defective, whether because it understates the required 90 days, uses the wrong guideline percentage, or is missing required information, the tenant can challenge the increase and it may be declared void
- A rent increase cannot be backdated, and a tenant who continues paying the old rent after an invalid notice is not automatically obligated to pay the higher amount
Timeline: How the N1 Process Actually Plays Out
Understanding processing time matters because both tenants and landlords often assume rent increases happen faster or more automatically than they do under Ontario law.
| Step | What Happens | Typical Timing |
|---|---|---|
| Guideline announcement | Ontario government publishes the following year’s guideline | Usually by mid-year for the following calendar year |
| Earliest N1 service date | Landlord serves Form N1 to tenant in writing | Exactly 90 days before the intended effective date |
| Notice review period | Tenant reviews the notice for accuracy, amount, and timing | Falls within the 90 day window |
| Increase takes effect | New rent amount becomes legally payable | On the exact date stated on the N1, not before |
| Dispute window | Tenant can file a complaint if the notice appears invalid | Can be raised any time after service, including after the increase takes effect |
When the New Rent Actually Needs to Be Paid
Once a valid N1 has been served and the 90 day notice period has passed, the new, higher rent becomes payable starting from the effective date listed on the notice, and not a day earlier. This is where the payment schedule becomes important for both sides.
- If rent is paid monthly, the new amount applies to the first full rent payment due on or after the effective date
- If the effective date falls in the middle of a rent period, only the portion of rent from the effective date forward is subject to the new rate, and the increase cannot be applied retroactively to days already paid at the old rate
- Tenants should keep both the original N1 notice and updated payment records, since these documents are the primary evidence used if a dispute over the amount or timing ever reaches the Landlord and Tenant Board
- Landlords cannot demand a lump sum “catch-up” payment covering the gap between the old and new rent for any period before the effective date
Which Units Are Exempt From the Guideline
Not every rental unit in Ontario is covered by the annual rent increase guideline, and this exemption has become a growing source of confusion as more newer buildings enter the rental market.
Units generally covered by the guideline:
- Most private residential rental units first occupied for residential purposes before November 15, 2018
- The majority of purpose-built rental apartments across older buildings in Toronto, Ottawa, Hamilton, and other established Ontario cities
Units generally exempt from the guideline:
- Any residential unit first occupied for residential purposes on or after November 15, 2018, including most new condo rentals and newly built purpose-rental towers
- Social housing and community housing units, which follow different rent-setting rules
- Long-term care homes and licensed retirement homes, which are governed by separate legislation
- Commercial properties and most seasonal or vacation rental units
For an exempt unit, a landlord can technically raise rent by any amount with proper notice, though tenants in these units still retain the right to challenge an increase they believe is being used in bad faith, such as to force them out of the unit.

When a Landlord Can Go Above the Guideline
Some landlords are permitted to raise rent beyond the 1.9 percent guideline, but only through a formal process, not simply by choosing to do so.
- Above Guideline Increases, commonly called AGIs, require landlords to file an application with the Landlord and Tenant Board and prove specific, eligible capital expenses such as major structural repairs, elevator replacements, or new roofing
- A significant increase in municipal property taxes can also justify an AGI application in some circumstances
- Vacant units are not subject to the guideline at all, meaning a landlord can set a new rent freely once a tenant has moved out and a new tenant is signing a fresh lease
- Agreements between a landlord and tenant to raise rent by more than the guideline in exchange for specific new services or amenities are possible but must be voluntary and cannot be a condition tied to threats of eviction
What Tenants Should Do If They Receive an N1 Notice
Receiving a rent increase notice can feel alarming, but Ontario tenants have clear, structured options for responding.
- Confirm the effective date on the notice and check which year’s guideline should legally apply, since a notice dated in late 2026 for a 2027 effective date must use 1.9 percent, not 2.1 percent
- Verify that at least a full 90 days of notice has been given and that it has been exactly 12 months since your last rent increase
- Check whether your unit was first occupied before or after November 15, 2018, since that single date determines whether the guideline applies to you at all
- If something looks incorrect, raise it with the landlord in writing first, and keep copies of all correspondence
- If the issue is not resolved, file a formal dispute or inquiry with the Landlord and Tenant Board, which can review the notice and rule on whether the increase is valid

FAQs About Ontario Rent Increase Guideline 2027
What is Ontario’s rent increase guideline for 2027?
The confirmed rent increase guideline for 2027 is 1.9 percent, applying to rent increases that take effect on or after January 1, 2027.
When can a landlord serve an N1 notice for a 2027 rent increase?
A landlord can serve Form N1 as early as October 3, 2026, since Ontario law requires a full 90 days written notice before a January 1, 2027 effective date.
Does the 2027 guideline apply to a notice served in 2026?
Only if the increase takes effect on or after January 1, 2027. What matters is the effective date on the notice, not the date the landlord serves it, so a notice served in October 2026 for a January 2027 increase must use the 1.9 percent figure.
Which rental units are exempt from Ontario’s rent increase guideline?
Units first occupied for residential purposes on or after November 15, 2018 are generally exempt, along with social housing, long-term care homes, and commercial properties.
Can a landlord raise rent by more than 1.9 percent in 2027?
Only through a formal Above Guideline Increase application to the Landlord and Tenant Board based on eligible capital expenses, or on a vacant unit being rented to a new tenant, or with a genuinely voluntary agreement tied to added services.
How much notice does a landlord have to give before raising rent in Ontario?
Landlords must give at least 90 days written notice using Form N1, and rent can only be increased once every 12 months for the same tenant.
What happens if a landlord’s rent increase notice is invalid?
An invalid notice, such as one giving less than 90 days notice or applying the wrong guideline percentage, can be challenged at the Landlord and Tenant Board and may be declared void, meaning the tenant is not obligated to pay the increased amount.
Is there a rent increase calculator for Ontario’s 2027 guideline?
Yes, tenants and landlords can calculate the maximum allowable increase by multiplying current rent by 1.9 percent, for example a $2,000 rent multiplied by 1.9 percent adds $38.00, bringing the new rent to $2,038.00.
Why has Ontario’s rent increase guideline been dropping each year?
The guideline is tied to Ontario’s Consumer Price Index but capped at a legal maximum of 2.5 percent, and the recent decline from 2.5 percent in 2025 to 2.1 percent in 2026 and now 1.9 percent in 2027 reflects a slowing pace of measured inflation.
Can a tenant refuse to pay a rent increase in Ontario?
A tenant cannot simply refuse to pay a valid, properly served increase, but a tenant who believes the notice is invalid, improperly timed, or uses the wrong guideline can dispute it formally with the Landlord and Tenant Board before paying the higher amount.
Conclusion
Ontario’s 2027 rent increase guideline of 1.9 percent is the lowest cap the province has set since the pandemic-era freeze, and it comes with a hard deadline that both tenants and landlords need to track closely, since the earliest a valid N1 notice for a January 1, 2027 increase can be served is October 3, 2026. For tenants, the key protections remain the same: confirm the effective date, confirm the 90 day notice period, and confirm whether your unit is even covered by the guideline in the first place. For landlords, getting the timing and the correct year’s percentage right is the difference between a valid increase and one that can be challenged and voided at the Landlord and Tenant Board.
