Do I need a new gas line for my Toronto kitchen range?

Whether you need a new gas line depends on your existing setup — many Toronto homeowners can connect a new range to an existing gas line, but there are several factors that determine if new work is required.

The first thing to check is whether you currently have a gas line roughed in to your kitchen at all. Older Toronto homes — especially the post-war bungalows common in Scarborough, Etobicoke, and North York — were often built with gas lines already run to the kitchen. Century homes in neighbourhoods like The Annex or Leslieville may have older lines that need inspection before use. If you're switching from an electric range to gas, you'll almost certainly need a new gas line run from your main supply.

Key factors that determine your needs:

• Existing gas stub-out: If there's already a capped gas line behind or beside your range location, a licensed technician may only need to connect and test it — a relatively minor job
• Line capacity: Your existing line must be properly sized for the BTU demand of your new range. High-output ranges (professional-style units with 15,000–20,000 BTU burners) may require a larger diameter line than what's currently in place
• Shutoff valve: Ontario code requires an accessible manual shutoff valve within 6 feet of the appliance
• Flexible connector: The final connection from the gas line to the range must use a listed flexible connector — typically replaced whenever a range is swapped out

On the Toronto/GTA cost side, a simple connection to an existing stub-out runs roughly $150–$350. Running a new gas line from your basement or utility room to the kitchen typically costs $400–$900+, depending on distance, obstacles, and whether drywall needs to be opened. If your home's gas meter or service needs upgrading to handle additional load, costs can rise further.

This is not a DIY job. In Ontario, all gas work must be performed by a licensed technician registered with the Technical Standards and Safety Authority (TSSA). This applies to the connection, any new line work, and the final pressure test. Unpermitted gas work can void your home insurance and create serious safety risks.

Your next step is to have a TSSA-licensed gas fitter or HVAC contractor assess your current setup before purchasing your range — especially if you're upgrading to a high-BTU professional model. They'll confirm whether your existing line is adequate, properly sized, and up to current code.

You can find licensed gas and HVAC contractors serving the Toronto area through the Toronto Construction Network directory. Always ask to see their TSSA licence number before work begins.
