Longueuil: Licence or Development Permit for Large Signs

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

In Longueuil, Quebec, property owners and advertisers must confirm whether a licence or a development permit is required before installing a large sign. Municipal rules distinguish between temporary signage, commercial billboards, and structural signs attached to buildings; the applicable instrument can affect timelines, fees, and enforcement. This guide explains the typical distinctions, the practical steps to apply, common violations, and how enforcement proceeds at the municipal level. Because permitting terms and fees are set by municipal regulations and planning departments, consult the city for definitive requirements before ordering production or installation.

Check permit timing early to avoid costly removals or fines.

How enforcement works in practice

Inspectors may issue a notice or order requiring removal or modification. If ignored, the municipality can proceed with administrative actions or prosecute in court. Always request documentation for any permit or exemption the property owner claims.

Common violations and likely outcomes

  • Oversized billboard beyond authorized dimensions — likely order to reduce or remove, monetary penalty possible.
  • Unapproved illuminated sign — order to cease illumination and apply for retroactive permit.
  • Sign in prohibited zone (heritage, setback) — removal order and possible fines.

Action steps

  • Confirm whether the sign is classified as temporary, permanent, or billboard under municipal definitions.
  • Contact the city’s planning or permits office for pre-application advice.
  • Complete and submit the development permit or licence application as required.
  • Pay applicable fees and await written authorization before installation.
Getting written confirmation avoids removal orders and enforcement delays.
