Utilities and Infrastructure Quebec 4 Minutes Read · published May 24, 2026 Flag of Quebec · By Daniel Roy

Longueuil, Quebec requires contractors who install, modify or inspect gas systems to meet provincial licence standards and municipal permit rules. This guide explains who enforces the rules, how to obtain permits and licences, inspection expectations, common violations and practical steps for contractors working in Longueuil.

Who regulates gas installers in Longueuil

The primary regulator of tradesperson licences for gas work in Quebec is the Régie du bâtiment du Québec (RBQ); municipal staff in Longueuil issue building permits and perform on-site inspections related to municipal bylaws and the local permitting process. For provincial licence requirements see the RBQ page and for municipal permit rules see the City of Longueuil permits and inspections page City of Longueuil permits & inspections[1] and the RBQ information for entrepreneurs RBQ - Entrepreneurs[2].

Licences, qualifications and scope

  • Provincial licence: gas installation work is regulated by the RBQ; contractors must hold the appropriate RBQ licence or work under a licensed contractor as required by provincial law.
  • Certification and training: tradespeople must meet RBQ training and certification standards for gas work; specific class or division details are set by the RBQ and referenced on their site.
  • Municipal permits: most gas appliance installs or significant modifications in Longueuil require a municipal building or mechanical permit; see the City permit page for application steps and submission requirements City permits & inspections[1].
Hold both RBQ licence and municipal permit documents on site during work.

Permits, inspections and on-site requirements

Contractors must apply for applicable municipal permits before starting gas work. Inspections are scheduled by the city building division or by municipal inspectors; contractors often must notify the city at key stages (rough-in, pressure test, final). If the RBQ licence is required for a given task, present licence information on request to municipal inspectors.

  • Application timing: submit permit applications before work begins; processing times are shown on the City of Longueuil permit pages and may vary.
  • Inspection scheduling: request or wait for mandatory inspections at prescribed stages; inspectors may require rectification for noncompliant work.
  • On-site documentation: keep RBQ licence, permit copies and manufacturer installation instructions available for inspectors.
