Mississauga Rent Increase Caps - Ontario Rules

Housing and Building Standards Ontario 3 Minutes Read · published February 11, 2026 Flag of Ontario

Mississauga, Ontario tenants and landlords must follow provincial rent-increase rules set under Ontario law. This guide explains how annual rent increase caps work, when an increase may be unlawful, who enforces the rules, and practical steps to dispute or comply with rent changes in Mississauga.

How rent increase caps work

In Ontario the provincial government publishes an annual rent increase guideline that limits year-over-year increases for most private residential tenancies. A landlord must give proper written notice and follow the permitted timing for increases; some unit types and new buildings may be exempt. For the current guideline and explanatory details see the provincial guidance.[1]

Check the current annual guideline before calculating a rent change.

When an increase may be unlawful

  • Increasing rent above the published guideline without an approved exception or an approved application to the Landlord and Tenant Board.
  • Failing to give the required written notice of increase within statutory timelines.
  • Charging back unauthorized fees or attempting to disguise rent as a separate charge.

Penalties & Enforcement

Enforcement and remedies for unlawful rent increases in Ontario are handled by the Landlord and Tenant Board (LTB) and, for municipal property standards or by-law issues, by City of Mississauga By-law Enforcement. Tenants can apply to the LTB to challenge an increase or seek repayment for an unlawful overcharge; municipalities may investigate separate by-law or property standard complaints. For LTB application steps and forms see the tribunal pages.[2] For municipal complaint pathways contact Mississauga By-law Enforcement or Housing Services.[3]

  • Monetary fines: not specified on the cited page.
  • Repayment or abatement orders: the LTB may order repayment of unlawfully collected rent or other remedies; see the LTB for details.[2]
  • Court or tribunal orders: the LTB issues orders that are enforceable; follow instructions on the tribunal site.[2]
  • Enforcers: Landlord and Tenant Board (provincial tribunal) and City of Mississauga By-law Enforcement for municipal matters.[2][3]
  • Appeals and review: appeals of LTB decisions are governed by tribunal rules and judicial review; time limits and routes are set on the tribunal pages (see forms and filing instructions).[2]
  • Defences and discretion: the LTB considers defences such as procedural errors, exemptions for new units, or applications for above-guideline increases that were approved under specific capital expenditures or renovations; consult the LTB guidance for criteria.

Applications & Forms

The Landlord and Tenant Board publishes application forms and instructions for tenants and landlords to file disputes, including applications to challenge unlawful rent increases or to seek orders related to overcharges. Specific form names and filing fees are provided on the tribunal forms page; if a municipal form is required for a by-law complaint, details appear on the City of Mississauga site. If a named form or fee is not listed on the cited page, it is not specified on the cited page.[2][3]

Complete and keep copies of all notices and receipts before filing an application.

How-To

  1. Confirm the current provincial rent increase guideline and whether the unit or tenancy is exempt.
  2. Gather evidence: written notice of increase, lease, payment records, and any communication about the increase.
  3. File the appropriate LTB application using the tribunal forms and follow the filing instructions on the LTB site.[2]
  4. Attend the LTB hearing or mediation and present your documents and timeline.
  5. If the LTB issues an order, follow the tribunal's directions to seek enforcement or repayment; municipal enforcement may be used for related by-law issues.[3]
File promptly—tribunal and appeal time limits can be strict.
