A gas leak is not a plumbing inconvenience, it is a life-safety emergency. Natural gas and propane are both odorless in their natural state, which is why utility suppliers add the distinctive rotten egg smell of mercaptan as a warning agent. The moment you detect that smell, hear an unexplained hissing near a gas line or appliance, or notice other warning signs of a gas leak in your home, every second of delay increases the risk of fire, explosion, or carbon monoxide poisoning.
At Waterworks Plumbing & Drains, we provide professional gas leak repair services in Etobicoke, ON, responding to gas-related emergencies with the urgency and technical precision that this type of work demands. Our licensed gas technicians are trained, equipped, and authorized to locate, assess, and repair gas line failures in residential and commercial properties throughout Etobicoke and the greater Toronto area. This guide covers exactly what to do if you suspect a gas leak, who to call, and how our team can help restore your home to safety.
What Is the First Thing You Should Do If You Suspect a Gas Leak?
The immediate priority in any suspected gas leak situation is protecting human life. Property can be repaired. Every action you take in the first moments must be guided by that single principle. Here is the correct sequence:
- Stop what you are doing and do not create any sparks. Do not turn lights on or off, do not use appliances, do not start a vehicle in an attached garage, and do not use your mobile phone until you are outside the building.
- Leave the building immediately. Leave doors open as you exit to help ventilate the space, but do not stop to open windows or gather belongings. Instruct everyone in the home to leave with you.
- Move to a safe distance. Get well away from the building before using any electronic device. Natural gas disperses upward and outward, so moving to the street or a neighbour's property is advisable.
- Call 911 and your gas utility provider. In Etobicoke and most of the Toronto area, the gas utility is Enbridge Gas. Their emergency line operates 24 hours a day. Emergency responders will assess the scene before anyone re-enters.
- Do not re-enter the property. Wait for confirmation from emergency personnel that it is safe to return. Even after the visible threat is addressed, a licensed gas technician must inspect and repair the source of the leak before gas service is restored.
Waterworks Plumbing & Drains is available around the clock to dispatch a licensed gas technician once emergency services have cleared the scene. Call (647) 947-9032 as soon as it is safe to do so.
What Must Be the First Concern When Responding to a Gas Leak?
Whether you are a homeowner, a property manager, or a first responder, the overriding concern in any gas leak situation is eliminating ignition sources and evacuating all occupants. Natural gas becomes flammable at concentrations as low as five percent in air, and explosive at higher concentrations. A single spark from a light switch, a phone screen illuminating, or even static electricity from clothing can trigger ignition in a gas-saturated environment.
This is why trained gas technicians follow a strict protocol when arriving at a gas leak scene: confirming that the area has been evacuated, assessing the concentration of gas with detection equipment before entry, and only proceeding once the environment is confirmed safe. As a homeowner, your role is not to locate or address the leak yourself. Your role is to get every person and pet out of the building as quickly and calmly as possible, then let trained professionals take over.
Our licensed gas technicians at Waterworks Plumbing & Drains are trained in exactly this protocol. We arrive equipped with gas concentration meters and pressure testing tools, and we do not proceed with any repair work until the environment is confirmed safe for entry.
What Should You NOT Do If You Suspect a Gas Leak?
Knowing what to avoid is just as important as knowing what to do. Several instinctive reactions that seem helpful are in fact dangerous when gas is present:
- Do not turn any electrical switches on or off. Both actions create a small spark that is sufficient to ignite gas at dangerous concentrations.
- Do not use your mobile phone, landline, or doorbell inside the building. These devices can produce the spark needed to trigger ignition.
- Do not light a match, candle, or cigarette. Open flames are an obvious ignition source and must be avoided entirely until the area has been cleared.
- Do not try to locate or fix the leak yourself. Gas line repair requires a licensed gas technician with the proper tools and training. Attempting to tighten fittings or shut off a gas valve without proper training can worsen the situation.
- Do not use any appliances, including the stove, oven, furnace, or dryer. Appliance ignitors create sparks, and the motor in an appliance fan can also trigger ignition.
- Do not re-enter the building until emergency services have confirmed it is safe. The all-clear must come from qualified personnel, not a personal judgment call.
- Do not assume a faint smell means the leak is minor. Gas concentrations can vary within a space, and even a small leak in an enclosed area can reach dangerous levels quickly.
Who Should You Contact for a Gas Leak in Etobicoke?
Gas leak response involves multiple parties, and understanding who handles what helps you act quickly and correctly.
Step 1: Call 911
Emergency services should always be your first call. Fire crews are trained and equipped to assess gas concentrations and secure the scene. They can also coordinate with the utility provider if necessary.
Step 2: Call Enbridge Gas Emergency Line
Enbridge Gas is the natural gas distributor for Etobicoke and most of the Toronto area. Their emergency line is available 24 hours a day and their technicians can shut off the gas supply at the meter or at the street-level service connection. The Enbridge emergency number is 1-866-763-5427. Enbridge is responsible for the gas main and the service line up to and including the meter.
Step 3: Call a Licensed Gas Technician for Repair
Once emergency services have cleared the scene and the gas supply has been shut off, the work of locating and repairing the source of the leak begins. This is the responsibility of a licensed gas technician working on your private property, not Enbridge. The utility provider does not repair internal gas lines, appliance connections, or fittings within your home.
Waterworks Plumbing & Drains provides licensed gas line repair services in Etobicoke and across Toronto. Our technicians use pressure testing and gas detection equipment to pinpoint the exact source of the leak, complete the necessary repairs to your internal gas piping or appliance connections, and conduct a final pressure test to confirm the system is sealed before your service is restored.

What Causes Gas Leaks in Homes?
Understanding the common causes of residential gas leaks helps homeowners recognize risk factors and take preventive action. The most frequent causes our team encounters in Etobicoke homes include:
Aging or Corroded Gas Lines
Older homes may have gas lines made from materials that are more susceptible to corrosion, stress cracking, or joint failure over time. Black iron pipe, which is common in older residential installations, can corrode at fittings and threaded connections as it ages. A professional inspection of your gas line infrastructure is recommended if your home is more than 20 to 25 years old and the lines have never been assessed.
Loose or Deteriorated Fittings and Connections
The threaded connections, unions, and flexible appliance connectors that join your gas piping to appliances are among the most common sites for slow leaks. Over time, pipe sealant compounds can dry and crack, flexible connectors can develop micro-fractures, and fittings can work loose due to minor ground movement or vibration from appliances. These leaks are often small and slow but accumulate to dangerous concentrations in enclosed spaces.
Appliance Movement or Improper Installation
Moving a gas-connected appliance such as a stove or dryer without properly disconnecting and reconnecting the flexible supply line is a frequent cause of gas leaks in kitchens and laundry rooms. Flexible connectors are not designed to accommodate the stress of being pulled or twisted. Any time a gas appliance is moved or replaced, the connection should be inspected or reinstalled by a licensed technician.
Physical Damage to Gas Lines
Renovation work, landscaping, accidental impact from a vehicle, or ground movement from frost heave can all cause physical damage to gas lines. Indoor gas lines run inside walls, floors, and utility chases and can be inadvertently nicked or severed during renovations if the line locations are not confirmed before work begins.
Faulty Appliances
A malfunctioning gas valve inside a furnace, water heater, or stove can allow gas to escape even when the appliance is not in use. Regular servicing of gas-burning appliances is one of the most effective preventive measures available to homeowners.
