Who to Call to Cap a Gas Line in Ontario
If you are removing an appliance, renovating a kitchen, or decommissioning an unused gas connection, you need to have the line properly capped by a TSSA-licensed gas technician. In Ontario, it is illegal to cap or modify a gas line yourself, even if the appliance has been removed. An improperly capped line creates a serious leak and explosion risk.
When You Need a Gas Line Capped
- Removing an old gas stove or dryer
- Demolishing a wall with a gas stub-out
- Replacing gas appliances with electric alternatives
- Decommissioning a gas fireplace or furnace
- Pre-sale home inspection requiring gas line work
What the Capping Process Involves
- Shutting off gas supply to the line being capped
- Installing a certified steel or brass cap at the stub-out
- Pressure-testing the capped connection
- Restoring gas to the rest of your home
- Providing documentation for your records

Do I need a permit for a new gas line?
Yes. In Ontario, all new gas line work requires a permit and must be inspected by a TSSA-authorized inspector. We handle the permit and inspection as part of every installation.
How much does a gas BBQ line cost?
A natural gas line for a BBQ typically costs $300–$600 depending on the distance from your gas meter and whether the line needs to go through walls or underground. We provide a firm quote before any work begins.
How long does a gas line installation take?
Most residential gas line jobs take 2–4 hours. Longer runs, underground lines, or complex routing through finished spaces may take a full day.
Can I run a gas line myself in Ontario?
No. Ontario law requires all gas line work to be performed by a licensed gas contractor (G1 or G2 license). Unlicensed gas work voids your home insurance and can result in fines.
What's the difference between a G1 and G2 license?
A G2 license covers natural gas systems up to 400,000 BTU - sufficient for most residential appliances. A G1 license covers all gas work including large commercial systems and propane. Our technicians hold both.
What should I do if I smell gas?
Leave the building immediately, don't use any light switches or electronics, and call Enbridge Gas Emergency at 1-866-763-5427 from outside. Once the utility has cleared the scene, call us for repairs.
