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

In Longueuil, Quebec, roadside advertising and signage near streets and intersections are regulated to protect driver sightlines and public safety. This guide explains how municipal rules apply to setbacks, visibility triangles, permitted locations, and the typical process for permits and compliance. For authoritative details consult the City of Longueuil bylaws and by-law enforcement pages to confirm permit requirements and any site-specific conditions.[1] If the consolidated bylaw text is not explicit about a detail, the municipal inspections office is the enforcing authority for interpretations and permits.[2]

Scope and Key Concepts

Roadside advertising here means permanent and temporary signs, billboards, and other displays visible from public rights-of-way. Important technical terms include:

  • Visibility triangle - the clear sight area at an intersection or driveway.
  • Setback - the required horizontal distance from a property line or curb to a sign.
  • Permit - municipal authorization where required to install or alter signs.
Check corner sightlines before installing any freestanding sign.

Design and Location Requirements

Typical municipal controls address maximum sign height, minimum setback from streets and intersections, and restrictions within visibility triangles adjacent to driveways and crosswalks. The City’s zoning and signage chapters set allowed zones and prohibited placements.

  • Minimum setbacks from curb or property line: not specified on the cited page.
  • Restrictions within sight triangles at intersections and driveways: not specified on the cited page.
  • Height limits, illumination and structural requirements: not specified on the cited page.

Penalties & Enforcement

The municipal enforcement framework covers inspections, orders to remedy non-compliant signs, administrative fines, and possible legal proceedings in court. Where the consolidated bylaw text or the official enforcement page does not list specific amounts or graduated penalties, the source is noted as not specifying them and the inspections office should be contacted for particulars.[1]

  • Fine amounts: not specified on the cited page.
  • Escalation for repeat or continuing offences: not specified on the cited page.
  • Non-monetary remedies: orders to remove or alter signs; possible court action for persistent non-compliance.
  • Enforcer: municipal By-law Enforcement and Inspections (contact via the City of Longueuil enforcement pages).[2]
  • Appeals/review: where specified, appeals follow municipal procedures and must be filed within the time limits stated on the order or notice; if no time limit is listed on the referenced page, time limits are not specified on the cited page.
Failure to comply can lead to removal orders and municipal charges.

Applications & Forms

Permit requirements and specific application forms for signs are managed by the City’s urban planning or permits office. The municipal site should list the application name and submission method; if a specific form number or fee is not published on the sign-related bylaw page, it is not specified on the cited page and applicants must contact the permits office directly.[2]

  • Permit name/number: not specified on the cited page.
  • Fees: not specified on the cited page.
  • Submission method: typically online or in-person through municipal permits services; check the City permit portal.

Action steps: contact the municipal permits office to confirm whether a sign permit is required, submit drawings showing setbacks and sightlines, obtain written authorization before installation, and keep copies of permits on site.

Common Violations

  • Signs placed within intersection or driveway sight triangles.
  • Over-height freestanding signs or signs extending into the public right-of-way.
  • Installation without a required municipal permit.
