Ontario rent increase guideline for 2027: 1.9%
Per ontario.ca, the guideline is 1.9% for 2027 and 2.1% for 2026. It is the maximum a landlord can increase most tenants’ rent during a year without the approval of the Landlord and Tenant Board. Rent can go up once 12 months have passed since the last increase or the start of the tenancy, with at least 90 days’ written notice on the proper LTB form. Units first occupied for residential purposes after November 15, 2018 are exempt from the guideline.
