Safety First
Why Licensed Gas Work Matters
Natural gas is one of the safest and most efficient energy sources available — when the infrastructure is properly installed and maintained. Unlicensed or improperly performed gas work is one of the leading causes of residential fires, explosions, and carbon monoxide incidents in Ontario.
In Ontario, all gas line work must be performed by a TSSA-licensed gas technician and is subject to permit and inspection requirements. Our G1 and G2 licensed technicians bring the training, tools, and accountability that gas work demands.
If You Smell Gas
Leave immediately. Do not use electrical switches, phones, or open flames inside. Call Enbridge Gas Emergency at 1-866-763-5427 from outside. Then call us for emergency repair service.

Safe, Permitted, Inspected
Our Gas Line Installation Process
Site Assessment & Design
We assess your gas meter capacity, existing piping, and the requirements of the new appliance or line to design a properly sized and routed gas system.
Permit Application
We apply for all required gas permits with the Technical Standards and Safety Authority (TSSA) before any work begins — ensuring full code compliance from the start.
Licensed Installation
Our G1 or G2 licensed technician installs the gas line using approved materials and methods, following all Ontario gas code requirements for routing, support, and connections.
Pressure Test & Inspection
We pressure-test the completed installation to verify it is leak-free, then coordinate the required TSSA inspection before commissioning the new appliance.
Safety Indicators
Gas System Warning Signs — Act Immediately
Recognizing early warning signs can prevent a minor issue from becoming a costly emergency. If you notice any of the following, contact our team for a professional assessment.
Smell of Natural Gas (Rotten Egg Odour)
Natural gas is odourized with mercaptan to make leaks detectable. Any smell of rotten eggs or sulphur inside your home requires immediate evacuation and emergency response.
Yellow or Orange Burner Flames
Gas appliances should burn with a blue flame. Yellow or orange flames indicate incomplete combustion, which can produce carbon monoxide. Call us for immediate inspection.
Unexplained Increase in Gas Bills
A significant increase in your gas consumption without a corresponding change in usage patterns can indicate a gas leak or a failing appliance that is consuming more gas than it should.
Carbon Monoxide Detector Alarm
A CO detector alarm is a serious emergency. Evacuate immediately, call 911, and do not re-enter until emergency services have cleared the building. Then call us for gas system inspection.
Visible Corrosion on Gas Piping
Rust, corrosion, or physical damage visible on gas pipes or fittings requires prompt professional inspection. Corroded gas lines can develop leaks without warning.
Gas Piping Over 30 Years Old
Older gas piping systems, particularly those using older materials, may be approaching the end of their service life. A professional inspection can identify any concerns before they become emergencies.

Frequently Asked Questions
What should I do if I smell gas?
Leave the building immediately, don't use any electrical switches or open flames, and call Enbridge Gas at 1-866-763-5427 from outside. Once the utility has cleared the area, call us for emergency repair service.
Do I need a permit for gas line work?
Yes — all gas line work in Ontario requires a permit and must be performed by a TSSA-licensed gas technician. We handle all permitting and inspections as part of our service.
Can I add a gas BBQ hookup to my backyard?
Absolutely — we install dedicated gas lines for outdoor BBQs, fire pits, and patio heaters. A permanent gas line is much more convenient than propane tanks and often pays for itself quickly.
How long does gas line installation take?
A simple appliance connection takes 1–2 hours. A new gas line run from the meter to a new appliance location typically takes 3–6 hours depending on distance and access.
What is a gas pressure test?
A pressure test verifies that your gas piping system is leak-free and holding proper pressure. We perform pressure tests on all new installations and repairs as required by Ontario gas code.
