Ontario rent increase guideline calculator (2026–2027)

The Ontario annual guideline is 2.1% for increases effective in 2026 and 1.9% for increases effective in 2027. This tool shows guideline arithmetic only. It does not decide whether a unit is exempt or whether a proposed increase is legally valid.

Before relying on the number

1. Confirm whether the unit is rent-controlled: some units first occupied for residential purposes after November 15, 2018 are exempt.
2. Normally check at least 12 months since the initial rent or last lawful increase and proper advance written notice (usually at least 90 days).
3. Check whether above-guideline approval, a special agreement or another exception applies.
