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

In London, Ontario, signs on private property and business premises are regulated by municipal bylaws and city sign policies. This guide explains the permit process, typical size standards, who enforces the rules, and how to apply or appeal. It summarizes what the City publishes about signs and advertising, what applicants should prepare, and the usual compliance steps property owners and tenants face when installing or changing signage. Where official pages do not list numeric limits or fees explicitly, this article notes that fact and directs you to the City of London resources for current, authoritative details.

Check the City of London signs pages before ordering fabrication to avoid costly rework.

Overview of Sign Permits and Size Standards

The City of London maintains official guidance and bylaws governing signage, including permit requirements for permanent and many temporary signs, location rules, and standards that affect maximum area, height, and setbacks. Exact dimensional limits, exemptions, and application forms are published on the City site; some numeric values are set in bylaw schedules or design guidelines and may vary by zone or sign type. See the City of London signs guidance for details City signs guidance[1] and the consolidated bylaws page for legal text City bylaws[2].

Penalties & Enforcement

Enforcement is handled by the City's By-law Enforcement and the Planning/Building divisions depending on whether the issue is a bylaw breach or a building permit matter. The City may issue orders to remove or alter non-compliant signs and pursue fines or court action for ongoing contraventions.

  • Fines and monetary penalties: not specified on the cited page; consult the City bylaws and enforcement pages for exact amounts and ticketing practice.[2]
  • Escalation: first offence, repeat and continuing offences are addressed under the municipal enforcement framework, but specific fine schedules or escalating ranges are not specified on the cited pages.[2]
  • Non-monetary sanctions: removal orders, stop-work instructions, and court injunctions or seizure are possible remedies under the bylaw and planning enforcement powers.[2]
  • Enforcers and contacts: By-law Enforcement and the Building Division administer compliance; complaint and contact pages are published on the City site for reporting violations.[1]
  • Appeals and review: appeal routes depend on the instrument issuing the order (bylaw ticket, building order or committee decision); specific appeal time limits are not specified on the cited pages and should be confirmed with the issuing office.[2]
If a sign is already installed, report concerns promptly because enforcement remedies may be time-limited.

Applications & Forms

  • Sign Permit Application: the City publishes permit requirements and application steps; the exact form name, number and current fee schedule are provided on the City signs guidance and permits pages (see links).[1]
  • Fees: permit fees and inspection fees are set by municipal fee schedules; if not listed on the signs page, they appear in the City fee bylaw or on the permits submission page (not specified on the cited page).[2]
  • Deadlines and lead times: processing times vary by application complexity and zoning review; no uniform statutory deadline is listed on the cited pages.

Action steps: prepare site plans, scaled drawings showing dimensions and setbacks, mounting details, and a completed application; submit to the Building Division or Planning staff as directed on the City application page and pay any applicable fee.

How-To

  1. Check the City of London signs guidance and applicable bylaw text to confirm whether your sign type requires a permit and any zone-specific limits.[1]
  2. Prepare a sign drawing with dimensions, area calculation, location on the building or property, and mounting details.
  3. Contact the City planning or building office for a pre-application check if your sign is large, illuminated, or attached to a building façade requiring structural review.
  4. Complete the Sign Permit Application and attach required documents, including proof of ownership or consent from the property owner.
  5. Submit the application and pay the fee; respond promptly to requests for additional information from City staff during review.
  6. If ordered to remove or alter a sign, follow the City direction and, if you wish to challenge the order, file the specified appeal or review within the time limit provided on the enforcement notice (confirm with the issuing office).[2]
A pre-application inquiry with planning or building staff can prevent design choices that trigger refusals or orders.
