Hayes Plumbing offers gas line installation in Whitby and Brooklin, running new natural gas piping to BBQs, stoves, dryers, fireplaces, water heaters and outdoor heaters, and repairing lines that leak. If you are looking for a gas fitter in Whitby, the most useful thing to know is that Ontario treats gas work differently from plumbing: the business doing it must be registered with the Technical Standards and Safety Authority (TSSA), and the people doing it must hold TSSA gas technician certificates. Enbridge Gas supplies natural gas in Whitby, and the Town of Whitby issues any building permit the project needs.
Whitby building permits and gas fireplaces
The Town of Whitby's list of projects that require a building permit includes new fireplaces and the completion of roughed-in fireplaces, along with plumbing, drains and heating systems. Oshawa's permit guide exempts gas fireplaces, but Whitby's list does not separate gas units from wood-burning ones, so confirm with the Town's Building Services Division before a gas fireplace goes in.
Residential applications go through the Town's E-Portal or on paper at Building Services, 3050 Garden Street, Unit 102. Inspection requests received by 3 p.m. can be scheduled for the next business day.
The gas piping is regulated on a separate track. The installation rules come from the CSA B149.1 code, which the province adopts under its gaseous fuels regulation, and TSSA audits the registered contractors who do the work through its Heating Contractor Audit Program.
How to check a gas fitter before you hire
TSSA keeps an online lookup of authorized fuels contractors and runs an annual Fraud Prevention Month campaign about unregistered workers it calls trunk slammers. Its warning signs are a contractor who cannot give you a TSSA registration number, quotes a price over the phone without seeing the job, asks for a large cash advance before any equipment or materials arrive, will not give a full business address and phone number, or will not name customers they have worked for in your area.
Those checks matter on small jobs too. A BBQ line or a dryer hookup is still gas work, and TSSA reports that about 65 per cent of fuels-related incidents in its historical data were caused by issues including substandard installation of fuel-burning appliances and poor maintenance.
Backyard and kitchen gas lines in Whitby
A natural gas BBQ line in a Whitby backyard often means a buried run from the house to the deck or patio. Before the first shovel goes in, a locate request has to reach Ontario Dig Authority, the new name for Ontario One Call, at least 5 business days ahead. An existing BBQ or pool heater gas line is private infrastructure that the public locate does not cover, so it needs a private locate.
Inside the house, the usual requests are a gas range for a kitchen renovation, a dryer line in the laundry room and supply lines for a water heater or fireplace. Ontario law requires a working carbon monoxide alarm next to each sleeping area in any home with a fuel-burning appliance, a fireplace or an attached garage. In 2024, Whitby Fire and Emergency Services received 402 combination smoke and CO alarms for local homes through Safe Community Project Zero, a program funded by Enbridge Gas.
Gas line cost for Whitby homes
We do not publish a gas line price range in our 2026 cost guide. The quote depends on how far the appliance is from the meter, how many appliances the line will feed, whether the route crosses an open basement ceiling or finished space, and how much digging an outdoor line needs. A Town of Whitby permit fee only applies when the project needs a permit, such as a new fireplace. Every Whitby job starts with a free in-home estimate and a written quote.
