What counts as an illegal rent increase in Ontario?
An illegal rent increase is any raise that breaks the rules set out by the province or the Residential Tenancies Act. Common examples include increases without proper written notice, increases that exceed the annual guideline without Landlord and Tenant Board approval, or raises applied during a fixed-term lease when the lease prohibits them. If you want a plain-language overview of rent rules and examples, see Understanding Rent Increases: What Tenants Need to Know. You can also review your rights under provincial rules and ask for LTB help if needed.[2]
Common signs of an illegal increase
- Landlord raises rent without proper written notice.
- Increase exceeds the provincial guideline or lacks LTB approval for an above-guideline increase.
- Rent is raised during a fixed-term tenancy before the lease ends.
What you can do
Start by comparing the notice to previous rent amounts and your lease. Collect receipts and a copy of the rent increase notice, then ask the landlord in writing for the legal basis for the raise and any LTB approval. Compare local rents to see if the increase looks out of line — you can Houseme - your rental solution in Canada to view comparable listings.
