Ontario Rent Increase Guideline 2027: Awaiting Announcement
Ontario has not announced the 2027 rent increase guideline yet. The number normally lands in late June, which means any N1 you serve right now still falls under the 2026 cap of 2.1%.
Bottom line
- The 2027 guideline is not published. Expect the announcement in late June 2026.
- Increases taking effect in 2026 are capped at 2.1%, set under O. Reg. 516/06 s. 8 and the Ontario Consumer Price Index.
- Do not serve an N1 with a 2027 increase amount before the announcement. It will be invalid.
What we know as of May 2026
Ontario has not released the 2027 rent increase guideline. The Ministry of Municipal Affairs and Housing publishes the next year’s figure in late June through news.ontario.ca and the residential rent increases page. The 2026 guideline (2.1%) was published on that schedule. This page will be updated within 24 hours of the 2027 announcement.
How the guideline is calculated
The guideline tracks the Ontario Consumer Price Index. O. Reg. 516/06 s. 8 sets the formula: the average CPI for Ontario over the 12-month period from June of the prior year to May of the current year. The statutory cap is 2.5% under RTA s. 120(2), even if CPI runs higher.
For the 2027 guideline:
- The calculation uses Ontario CPI from June 2025 to May 2026.
- The cap is 2.5%. If CPI exceeds 2.5%, the guideline stops at 2.5%.
- The announcement is expected in late June 2026.

What to do with N1 notices right now
Your live obligation is the 2026 guideline. Use 2.1% for any rent increase taking effect on or after January 1, 2026. The notice form is the N1, served at least 90 days before the new rent date, and a unit can receive only one increase in any 12-month window. Our N1 form guide walks through the fields. The 2026 guideline guide covers the math.
Do not pre-serve a 2027-cap N1 now. Without the announced 2027 figure, you cannot lawfully calculate the new rent. Any N1 served with a guessed 2027 amount is invalid, and the LTB will throw it out at the rent-increase application stage.
What happens once the 2027 number is announced
Within 24 hours of the official release, this page will reflect the published guideline. The N1 effective date for 2027 increases starts January 1, 2027. The 90-day notice rule under RTA s. 116(4) means you can serve an N1 with the 2027 amount as early as October 3, 2026 for a January 1, 2027 effective date.
