Frequently Asked Questions
How much can a landlord increase rent in Ontario?
For rent-controlled units, landlords can only increase rent by the annual guideline (2.1% in 2026, down from 2.5% in 2024 and 2025) once per year with 90 days written notice. Units first occupied after November 15, 2018 are exempt from rent control and have no limit.
When is a rent increase illegal in Ontario?
A rent increase is illegal if: it exceeds the guideline without AGI approval, occurs less than 12 months after the last increase, proper 90-day notice wasn't given, the notice doesn't use the proper N1 form, or it's applied to a new tenant (rent can't increase between tenancies for controlled units).
Can I refuse a rent increase?
If the increase is illegal (above guideline, improper notice, too soon), you can refuse it and continue paying your current rent. If the landlord persists, they may file with the LTB, where you can defend against the improper increase.
How long will my LTB case take?
Current processing times vary 3-12 months depending on application type and urgency. We work to move your case forward as efficiently as possible.
