London, Ontario Tenant Anti-Retaliation Rules

Housing and Building Standards Ontario 4 Minutes Read · published February 12, 2026 Flag of Ontario

In London, Ontario tenants have protections when they report unsafe or non-compliant housing conditions. This guide explains where anti-retaliation rules come from, how to report problems to the City and provincial bodies, what enforcement options exist, and practical steps tenants should take if a landlord retaliates for a complaint. It covers municipal complaint routes for property standards and the provincial Residential Tenancies Act process so you can act with evidence and deadlines in mind.

What the rules cover

Anti-retaliation protections generally apply when a tenant legitimately complains about health, safety, building or bylaw violations, or seeks enforcement action. In Ontario the Residential Tenancies Act (RTA) and the Landlord and Tenant Board address unlawful reprisals; municipal property standards and by-law enforcement address physical conditions and related complaints in London. For provincial statutory text see the Residential Tenancies Act referenced below[2].

When to report

  • When a condition risks health or safety (mould, plumbing failure, heating, electrical).
  • When a landlord refuses repairs after a written request.
  • When you receive an eviction notice or rent increase shortly after filing a complaint.
Document dates, messages and photos immediately after noticing a problem.

How to report in London

File a property-standards or by-law complaint with the City of London for building, pest, or sanitation issues; use the City reporting page to submit details and photos[1]. For reprisals specifically tied to tenancy rights, the Landlord and Tenant Board (LTB) handles claims under the Residential Tenancies Act; contact information for the LTB and application processes are available through provincial resources.

Penalties & Enforcement

Enforcement and remedies differ by jurisdiction and instrument:

  • Municipal enforcement (City of London) — compliance orders and property standards charges; monetary fine amounts are not specified on the cited City page[1].
  • Provincial remedies (Residential Tenancies Act) — the Landlord and Tenant Board can order remedies for unlawful reprisals; specific penalty figures or statutory fine amounts are not specified on the cited provincial page referenced here[2].
  • Escalation — first, repeat, and continuing offences: ranges and escalations are not specified on the cited pages.
  • Non-monetary sanctions commonly used or sought include compliance orders, repair orders, orders for compensation, termination of tenancy and other remedies via the LTB or municipal orders.
  • Primary enforcers: City of London By-law Enforcement (property standards and municipal bylaws) and the Landlord and Tenant Board for tenancy reprisals.
  • Appeals and reviews: appeals differ by forum — municipal order reviews or provincial appeal routes apply; specific time limits for appealing are not specified on the cited pages and will depend on the order or LTB decision.
  • Defences and discretion: decision-makers may consider reasonable excuse, imminent danger, or prior approvals; exact defences are case-specific and not numerically specified on the cited pages.
If you face immediate eviction or lockout, seek urgent legal advice and file with the Landlord and Tenant Board without delay.

Applications & Forms

  • City complaint form: submit a property standards or by-law complaint via the City of London reporting page[1].
  • LTB applications: the Landlord and Tenant Board uses specific application forms for claims; see LTB guidance (contact LTB for current forms and filing instructions).

Action steps for tenants

  • Document the issue: date-stamped photos, written requests to landlord, and copies of notices.
  • Report to the City for property standards issues using the City reporting page and keep the complaint number.
  • If you experience retaliation (eviction notice, threats, rent hike tied to complaint), consider filing an LTB application and collect evidence before filing.
  • Pay attention to deadlines for LTB applications or municipal reviews; if unsure, seek legal advice promptly.
Keep copies of every communication you send or receive about the issue.
