Ontario's 2027 rent increase guideline is 1.9%: what landlords need to know

Last updated October 22, 2026 · Written for small Ontario landlords

Ontario set the 2027 rent increase guideline at 1.9%, down from 2.1% in 2026. It's the most you can raise most tenants' rent in 2027 without LTB approval.

Quick math: $1,000 rent × 1.9% = $19 → new rent $1,019. A $1,450 room → +$27.55 → $1,477.55.

The rules

Worked example (from ontario.ca)

A lease starts June 1, 2026 at $1,000. The earliest increase is June 1, 2027. With 1.9%, the new rent is $1,019. The notice must reach the tenant at least 90 days before June 1, 2027, so by early March 2027. Add 5 days if you mail it.

Who the guideline does NOT apply to

If you rely on the post-2018 exemption, ontario.ca suggests adding a section 15 term to the standard lease saying the unit is exempt, and keeping proof such as building permits, contractor invoices and before-and-after photos.

The guideline is based on Ontario CPI and capped at 2.5%.

Don't forget: interest on last month's rent deposit

If you hold a rent deposit, you owe the tenant interest every year at the guideline rate (1.9% for 2027). When rent goes up, you can ask the tenant to top up the deposit to match. Many landlords simply apply the interest toward the deposit top-up. Check the LTB's Guide to the RTA for the details.

The toolkit's Rent & Expense Tracker has a guideline lookup (2.1% 2026 / 1.9% 2027), a rent ledger with a running balance, and CRA T776 expense categories.
