Security Deposit Rules - St. Catharines, Ontario

Housing and Building Standards Ontario 3 Minutes Read · published May 26, 2026 Flag of Ontario · By Daniel Roy

In St. Catharines, Ontario tenants frequently ask how security deposits and last-months' rent deposits are governed and returned. This guide explains the provincial framework that applies to rental housing used in St. Catharines, how to request a return, where to file disputes, and what municipal contacts can help with local issues. It summarizes the practical steps tenants should take when moving out, the timelines commonly observed, and how to preserve evidence if a dispute arises. Where the municipal role is limited, the province's Residential Tenancies Act and the Landlord and Tenant Board provide the controlling rules and dispute processes.

Overview of Deposit Rules

Ontario's provincial law controls most rules about rent deposits and what landlords may require from tenants in St. Catharines. Generally, a landlord may require a deposit applied to the last month's rent; other deposit types and conditions are governed by provincial rules and by decisions of the Landlord and Tenant Board.[1][2]

Keep a dated inventory and photos when you move in and out.

Typical Timelines for Return

  • Tenants should give written notice of move-out dates in the form required by their lease or the Residential Tenancies Act.
  • Landlords commonly apply a last-months deposit to final rent; the timing for returning any balance or resolving disputes depends on whether deductions are claimed.
  • If a deduction is claimed for damage, request an itemized list and receipts — timelines for returning disputed funds are not specified on the cited page.

Penalties & Enforcement

Enforcement of deposit rules and disputes over returns for tenants in St. Catharines is primarily managed through the Landlord and Tenant Board (LTB) and the province's Residential Tenancies Act; municipal bylaw offices generally do not determine deposit disputes between landlords and tenants. The statutory instrument and tribunal process set obligations, remedies, and how to seek orders or compensation.[1][2]

  • Monetary fines or provincial offence ticket amounts for deposit violations are not specified on the cited provincial pages.
  • Remedies typically involve LTB orders for repayment, compensation or abatement rather than fixed municipal fines.
  • Escalation and repeat offences: the cited sources do not list specific escalating fine schedules; the LTB may order remedies on an application.
  • Enforcer/decision-maker: Landlord and Tenant Board for tenancy disputes; municipal By-law Enforcement may handle unrelated municipal offences like illegal units or licensing issues.
  • Appeals/review: decisions of the LTB can be judicially reviewed by court within applicable time limits; specific time limits are set in tribunal rules and case law and are not specified on the cited provincial summary page.
If the landlord claims damage deductions, ask for an itemized invoice promptly.

Applications & Forms

Most deposit disputes require an LTB application. The LTB publishes the forms and filing instructions on its website; specific form names and fees are provided there. For municipal matters (e.g., licensing, illegal suites) contact the City of St. Catharines enforcement pages listed in Resources below.

What Tenants Should Do

  • Document move-in condition with dated photos and a signed checklist.
  • Keep receipts and communication (email/text) about deposits and repairs.
  • Request an itemized list of deductions in writing if the landlord retains deposit funds.
  • If informal resolution fails, file an application with the Landlord and Tenant Board to seek an order for return or compensation.
Start documentation the day you move in to avoid disputes later.
