Do I need a permit to add a gas line in Ottawa?

Adding a gas line in Ottawa always requires a permit and must be done by a licensed gas technician — this is not optional or a grey area.

In Ontario, any new gas piping installation is regulated by the Technical Standards & Safety Authority (TSSA). The work must be performed by a technician holding a valid G2 or G3 gas licence issued by the TSSA. Once the work is complete, it typically requires a TSSA inspection before the line can be put into service. Attempting this work yourself — or hiring an unlicensed person — is illegal and genuinely dangerous.

The City of Ottawa may also require a building permit depending on the scope of the project (for example, if the gas line is part of a larger renovation). The contractor you hire should be able to clarify which permits apply to your specific situation and will usually pull the necessary permits on your behalf as part of the job.

On the cost side, adding a gas line in Ottawa typically runs $500 – $1,500+ depending on the distance of the run, accessibility, and what appliance is being connected (a gas stove, fireplace, BBQ hookup, or new furnace all have different requirements). A longer run through finished walls or a concrete slab will cost more.

Safety note: If at any point during this project you smell gas, leave the property immediately and call Enbridge Gas at 1-866-763-5427. Never assume a gas smell is minor.
