Signs and Advertising Ontario 4 Minutes Read · published February 12, 2026 Flag of Ontario

In London, Ontario, electronic message centres on signs are regulated through the citys signs and permitting framework to protect safety, visual amenity and traffic sightlines. This guide explains when a permit is required, technical and illumination considerations, how the city enforces rules, and the practical steps to apply for or appeal a decision. It is intended for property owners, businesses and sign contractors working in London who need to comply with municipal sign requirements and avoid fines or orders.

What electronic message centre rules cover

Electronic message centres (EMCs) are dynamic or programmable sign faces integrated into freestanding signs, fascia signs, or other permitted sign types. The city regulates location, size, brightness, animation and hours of operation to reduce distraction and ensure compliance with zoning and road safety standards. For official program details and permit requirements see the City of London signs and advertising page City signs & advertising[1].

Confirm whether your site falls in a commercial, arterial or gateway zone before designing an EMC.

When you need a permit

  • Most permanent EMC installations require a sign permit from City of London Building Services; temporary or event signage may have different rules.
  • Applications usually must include scaled drawings, electrical details and a site plan showing set-backs and sightlines.
  • Fees and processing timelines are published with the application materials on the sign permit page Sign permit application[2].
Electrical connections for EMCs require compliance with Ontario electrical code and may need a separate electrical permit.

Design, illumination and safety standards

Standards typically control maximum sign area for illuminated faces, luminous intensity, scrolling or flashing restrictions, and automatic dimming at night. Exact numeric limits and measurement methods are set out in the citys sign guidance and technical specifications on the official sign pages City signs & advertising[1].

Penalties & Enforcement

The City of London enforces sign rules through Municipal Law Enforcement and Building Services. Enforcement tools include orders to remedy or remove non-compliant signs, administrative orders, and prosecution in court. If you receive a compliance order, the order will explain deadlines and appeal rights.

  • Monetary fines: specific fine amounts for sign bylaw offences are not specified on the cited pages.
  • Escalation: the city may issue initial warnings or orders followed by fines or court charges for continuing offences; exact escalation steps and dollar ranges are not specified on the cited pages.
  • Non-monetary sanctions: removal orders, stop-work directives, and court injunctions are available to the citys enforcement officers.
  • Enforcer and complaints: Municipal Law Enforcement and Building Services handle investigations and complaints; contact information is on the city website Laws, licenses & permits[3].
  • Appeals and review: appeal routes and time limits are stated on individual orders or permit decisions; if an appeal route is not printed on the decision, the enforcement notice will state how to challenge it and applicable deadlines are given there.
If you are served an order, act promptly to avoid escalation and additional charges.

Applications & Forms

The City publishes a sign permit application and checklist; the application lists required drawings, electrical details and submission instructions. Specific application form names and fee amounts are published on the sign permit application page Sign permit application[2]. If a fee table or form number is not visible on that page, the fee is not specified on the cited page.

Action steps

  • Prepare scaled plans, electrical drawings and a site plan showing the proposed EMC location.
  • Check the published fee and submit the sign permit application online or in person per the Building Services instructions.
  • Allow inspections: schedule electrical and sign inspections as required and retain records of approvals.
