Ontario Sets the 2027 Rent-Increase Guideline at 1.9% — What It Means for GTA Renters, Landlords and Investors

Ontario has quietly set its 2027 rent-increase guideline at 1.9%. The figure is now published on the province's official residential rent increases page, and it applies to rent increases that take effect on or after January 1, 2027. It continues a downward drift: the guideline was 2.5% in 2025 and 2.1% in 2026, and now steps down again to 1.9% for 2027.

For a market as rent-heavy as the GTA, a two-tenth-of-a-point move sounds like a rounding error. It isn't — but not for the reason most headlines suggest. The number that matters more than 1.9% is a date: November 15, 2018. We'll get to why below.

What the 1.9% guideline actually is

The guideline is the maximum a landlord can raise the rent of most existing, rent-controlled tenancies in a 12-month period without applying to the Landlord and Tenant Board. Per the province, it is calculated using the Ontario Consumer Price Index — Statistics Canada's measure of inflation — using data from June through May to set the following year's number. Critically, Ontario also notes the guideline "is capped at 2.5% to prevent significant one-time rent increases to tenants." So even in a high-inflation year, a rent-controlled unit can't be bumped past 2.5% under the guideline. For 2027, inflation math has landed the number well under that ceiling, at 1.9%.

In plain terms, on a covered unit a landlord can raise rent once every 12 months, and for any increase taking effect in 2027 that raise is limited to 1.9% — with 90 days' written notice on the proper provincial form.

What 1.9% looks like in dollars

The percentage is easy to shrug off until you annualize it against real GTA rents. Here is the arithmetic on a few illustrative monthly rents (these are example figures, not market averages — apply the 1.9% to your own rent):

Example monthly rent	Max increase per month (1.9%)	Extra per year
$1,800	$34.20	$410.40
$2,200	$41.80	$501.60
$2,800	$53.20	$638.40

So on a typical GTA two-bedroom, a fully-applied guideline increase runs a few hundred dollars a year. Meaningful for a household budget, but — and this is the point most coverage misses — only if your unit is actually covered.

The GTA catch: a lot of your rental stock isn't covered at all

Here's the local angle that matters more than the headline number. Ontario's guideline does not apply to, in the province's own words, "new buildings, additions to existing buildings and most new basement apartments that are occupied for the first time for residential purposes after November 15, 2018." Units are also exempt on turnover to a new tenant, along with community housing, long-term care and commercial units.

That November 2018 cut-off lands squarely on the GTA. A very large share of the region's newer rental supply — the purpose-built rental towers and investor-owned condos that have come online across Toronto, Mississauga, Vaughan, Markham and the 905 over the past several years — was first occupied after that date. For renters in those buildings, the 1.9% guideline is essentially a headline they can watch on the news but can't rely on: their increases aren't capped by it. This is why two neighbours paying similar rent in similar towers can face very different renewal letters — one protected at 1.9%, the other not.

The single most useful thing a GTA renter can do with this announcement is not memorize "1.9%." It's to find out when their specific unit was first occupied for residential purposes. That one fact determines whether the guideline protects them at all.

The read for each side of the table

Renters in older (covered) units: Your 2027 increase is capped at 1.9%, it can only happen 12 months after your last increase or your move-in, and it requires 90 days' written notice on the correct form. An increase that skips any of those conditions isn't automatically valid.

Renters in post-November-2018 units: The guideline doesn't cap you. Your leverage is the market, not the province — and in a GTA rental market that has softened from its 2024 peak, that leverage has been quietly shifting back toward tenants at renewal. Come to the conversation with comparable listings, not the 1.9% figure.

Small landlords with covered units: Budget renewals around 1.9% for 2027, and get the notice mechanics right — 12 months since the last increase, 90 days' notice, proper form. Getting the process wrong is a more common and costly mistake than getting the percentage wrong.

Investors and pre-construction buyers: The exemption for units first occupied after November 15, 2018 is a real part of the yield story on newer GTA condos — those units can be re-rented and adjusted to market on turnover rather than being held to the guideline. That flexibility is a feature to model, but it cuts both ways: in a soft rental market, "market rate" can move down as easily as up. Underwrite to today's rents, not last year's peak.

The bigger signal

Three years of a falling guideline — 2.5% to 2.1% to 1.9% — is itself a story. Because the number is derived from Ontario CPI, a lower guideline is a downstream reading on cooling inflation, the same force that shapes where mortgage rates go next. For the GTA, it lands on top of a rental market that has already come off the boil. None of that changes the mechanics above — but it does frame 2027 as a year where, for once, the pressure on renters is easing at the margin rather than building.
