Montréal Gas Safety Inspection for Businesses

Utilities and Infrastructure Quebec 3 Minutes Read · published February 11, 2026 Flag of Quebec

Montréal, Quebec businesses that use natural gas or other fuel-burning appliances must arrange timely safety inspections to comply with municipal permit rules and provincial construction standards. This guide explains who to contact in Montréal, how to request an inspection, what documents to prepare, and what to expect during enforcement and appeals. It focuses on practical steps for owners, facility managers and licensed contractors so you can keep people safe and operations compliant.

Before you book

Determine whether the work is a new installation, modification, or an annual/compliance inspection. For many commercial gas installs you will need a licensed contractor and a municipal permit before inspection. If you are unsure whether your project needs a permit, contact the City of Montréal permits and inspections service for confirmation.[1]

Always confirm permit requirements before hiring a contractor.

How to book a gas safety inspection

  1. Identify the scope: new install, alteration, repair or periodic compliance check.
  2. Hire a licensed contractor when required; obtain any contractor certificates or RBQ documents to show the installer is authorized.
  3. Contact the City of Montréal Permits and Inspections service to request the municipal inspection and confirm required permit numbers and documentation. City of Montréal — Building permits & inspections[1]
