In case of an emergency 
Leak or gas smell 

Call 9-1-1. If this service is not available in your region, call 1 800 361-8003.

Natural gas is odorless. An odorant is added to it to enable leaks to be detected.
This substance, mercaptan, gives off a strong smell of rotten eggs.

What to do in case of a gas leak?

1. Avoid flames and sparks.

  • Do not smoke.
  • Do not operate any devices near the leak, even a cell phone or light switch—static electricity could cause a spark.

2. Quickly exit the building or move away from the leak if you are already outside.

Without delaying your exit from the building, you can open doors and windows (or leave them open) on your way out to ensure maximum ventilation.

3. Call 9-1-1

Dizziness, nausea, and headaches

If you feel dizzy, nauseous, or have a headache, especially near a gas appliance, leave the building immediately and call 9-1-1 for medical assistance. A malfunctioning appliance can cause carbon monoxide poisoning. Other unusual situations, such as flooding, freezing rain, or heavy snow, may also require special measures. These are part of basic prevention.
