Signs and Advertising Quebec 3 Minutes Read · published May 24, 2026 Flag of Quebec · By Daniel Roy

In Longueuil, Quebec, digital signs and rotating electronic displays are subject to municipal rules administered through the city’s urban planning and by-law control services. This guide explains how the city treats brightness and rotation for electronic signage, how enforcement works, and the practical steps businesses and property owners should take to apply for permits, seek variances, or respond to complaints. It summarizes typical compliance checks, common violations and the actions you can take if you receive a notice or suspect a sign exceeds permitted limits.

Scope & definitions

Municipal rules that affect digital signage typically cover luminous intensity, automatic brightness adjustments, change intervals for rotating displays, display of video or full-motion content, and placement relative to public rights-of-way and residential zones. Exact technical thresholds (cd/m2, lux, or seconds per rotation) depend on the applicable municipal regulation or zoning provision that governs signage type and zone.

Penalties & Enforcement

The City of Longueuil enforces signage rules through its urban planning and by-law control services. Specific monetary fines are not specified on the official municipal pages listed in Resources below; where the bylaw text does specify amounts it will appear in the consolidated regulation or ticket schedule published by the city.

  • Enforcer: By-law control and urbanisme services (municipal inspectors and by-law officers) conduct inspections and issue notices.
  • Complaint pathway: file a complaint with the city’s by-law or urbanisme complaint form as shown in Resources.
  • Fines: not specified on the cited pages in Resources.
  • Escalation: first offence, repeat and continuing offences are handled per the municipal enforcement process; specific escalation amounts and continuing offence rules are not specified on the cited pages.
  • Non-monetary sanctions: orders to modify or turn off a sign, removal orders, stop-work or compliance orders, and referral to court where necessary.
  • Appeals/review: dispute of a ticket or order is typically resolved through the municipal tribunal process or the courts; time limits for appeals are not specified on the cited pages and should be confirmed with the city.
Inspectors can measure light or require a certified report to confirm compliance.

Common violations and typical outcomes:

  • Excessive brightness at night leading to nuisance complaints.
  • Too-rapid rotation or animation in zones where static displays are required.
  • Unauthorized location or size exceeding bylaw limits.
  • Failure to obtain required permit before installation.

Applications & Forms

Sign permits are handled by the city’s urban planning or building permitting section. Where a specific permit name, number, fee or form exists it will be published on the city’s permits and forms pages; if the municipality does not publish a dedicated sign form on the pages linked in Resources, an application is normally submitted through the urbanisme or building permit intake. Fees and deadlines are not specified on the cited pages.

Always request written confirmation of permit requirements before installing or retrofitting a digital sign.

Action steps

  • Before installing, contact Longueuil urbanisme to confirm whether a sign permit or building permit is required.
  • If you receive a notice, follow the correction order and document changes; request an inspector recheck once fixed.
  • If contested, ask the city for the appeal procedure and filing deadlines in writing immediately.
  • Report non-compliant signs via the city complaint channel listed under Resources.
