London sign bylaw - digital brightness and rotation

Signs and Advertising Ontario 3 Minutes Read · published February 12, 2026 Flag of Ontario

In London, Ontario, digital signs and electronic message centres must meet municipal rules that balance visibility with safety and neighbourhood character. This guide explains where brightness and rotation limits are set in City guidance, how enforcement works, and the steps property owners and advertisers should follow to apply for a sign permit, request a variance, or respond to a complaint.

Penalties & Enforcement

London enforces sign rules through municipal by-law powers and by-law officers within By-law Enforcement and Planning. The City publishes guidance on signs and advertising on its website; for official contact and reporting pathways see the City signs page City of London - Signs & Advertising[1]. The consolidated list of City by-laws is also available for reference City of London - By-laws[2]. Specific numeric limits for digital sign brightness (nits or candela) and rotation/transition intervals are not specified on the cited by-law summary pages and must be confirmed in the current consolidated by-law text or Planning staff guidance.

  • Fines and monetary penalties: not specified on the cited page; consult the consolidated by-law text or contact By-law Enforcement for current amounts.
  • Escalation: first and repeat offences, continuing offence provisions and daily fine structures are not detailed on the cited summary pages.
  • Non-monetary sanctions: orders to remove or modify signs, stop-work orders, compliance timelines, and court prosecution are enforcement options named in municipal enforcement practice; specific mechanisms should be confirmed with By-law Enforcement.
  • Enforcer and complaints: By-law Enforcement and Planning staff handle inspections, compliance letters and investigations; see the City signs page for contact and reporting procedures City of London - Signs & Advertising[1].
If a numeric brightness or rotation limit is required for your project, request the consolidated by-law text or Planning staff guidance before permitting work.

Applications & Forms

Sign permits, applications and technical requirements are administered by Planning and Development Services. Where available, application forms and submission instructions are provided on the City sign permits page Sign permits and requirements[3]. Fees, required drawings and electrical permits vary by sign type; if a specific application form number is not published on the City page, contact Planning staff for the current form and fee schedule.

Most electronic sign proposals require a full sign permit and may need a zoning or variance review depending on location.

Common Violations and Typical Responses

  • Unauthorised electronic message changes or animated displays when prohibited.
  • Excessive brightness at night causing nuisance or safety concerns to adjacent properties or road users.
  • Failure to obtain a required sign permit before installation.
  • Non-compliance with permitted sign dimensions, setbacks, or required intervals between rotations/animations.
