Montréal sign bylaw: size, height and materials

Signs and Advertising Quebec 4 Minutes Read · published February 11, 2026 Flag of Quebec

Montréal, Quebec requires permits and rules for most exterior signs and advertising on private and public property. This guide explains typical size, height and material standards used by the city, who enforces them, how penalties work, and the practical steps to apply, appeal or report a violation. Use the official permit pages and the bylaw references cited below to confirm specifics for your address and sign type before ordering fabrication.

Scope & basic standards

The City of Montréal regulates freestanding signs, façade signs, projecting signs, roof signs and digital displays. Specific maximum dimensions and permitted materials depend on zone (commercial, residential, heritage) and the sign type; exact numeric limits are set in municipal regulations or permit conditions and vary by location. For permit details and required drawings, consult the city’s signs and advertising permit page [1].

Heritage or protected districts often have stricter limits on size and materials.

Common dimensional rules by sign type

Municipal rules commonly distinguish:

  • Façade signs — mounted flat to building face; size often limited to a percentage of façade or storefront width.
  • Projecting signs — limited projection from wall and total area; clearance requirements above sidewalks.
  • Freestanding signs — maximum height and base setbacks from property lines; sometimes prohibited in residential zones.
  • Roof signs and digital displays — often subject to stricter height, setback and luminosity limits, and may be restricted in certain sectors.

Materials, illumination and safety

Materials must meet building and fire-safety codes. Illuminated signs must control glare and meet electrical code requirements; some installations require an electrical permit and inspection. The city may require corrosion-resistant fixings, wind-load calculations for large freestanding or roof signs, and professional drawings sealed by a qualified designer or engineer when structural impacts are anticipated. Where the regulation text or permit page does not list specific material standards or technical thresholds, those technical requirements are set during permit review or by referenced building codes and are not specified on the cited page [2].

Penalties & Enforcement

Enforcement is managed by municipal by-law officers and the city’s inspection services; complaints can be filed online or by phone. Fines, orders to remove, stop-work orders and court proceedings are possible. Exact monetary penalties are often set in the applicable bylaw or tariff; when a figure is not published on the relevant permit or summary page, the amount is not specified on the cited page [1].

  • Monetary fines — not specified on the cited page for all sign types; see the bylaw text or municipal tariff for exact amounts.
  • Non-monetary sanctions — removal orders, stop-work or seizure of unlawful signs until compliance.
  • Escalation — initial tickets, higher fines for repeat or continuing offences, and court prosecution for persistent non-compliance (specific ranges not specified on the cited page).
  • Inspection and complaints — file a complaint or request inspection through the city’s reporting services [3].
  • Appeals — decisions and orders typically have internal review or appeal routes to municipal tribunals or courts; time limits for appeals should be confirmed on the order or notice (not specified on the cited page).
If you install without a permit, the city can order removal and issue fines or pursue court remedies.

Applications & Forms

Permit applications, required drawings and submission instructions are available on the city’s signs and advertising permit page; fees and specific form names or numbers may be listed there for each permit type [1]. If a consolidated bylaw form or code section is needed, consult the city’s bylaws repository or contact the permitting office for the exact document reference [2].

Always confirm permit fees and required technical documents with the permit office before fabrication.

How-To

  1. Determine sign type and zoning for the property by checking municipal zoning maps or the permit guidance.
  2. Prepare drawings: location plan, elevations, dimensions, materials, illumination and structural notes if required.
  3. Apply for a sign permit online or at the designated municipal counter following the instructions on the official permit page [1].
  4. Pay applicable fees and schedule any required inspections (electrical, structural) as indicated by the permit review.
  5. Receive the permit decision; if refused, follow the appeal instructions on the refusal notice or contact the permitting office for review.
