How much does gas fitting cost in Toronto?

Simple jobs like connecting a gas stove or BBQ line typically run $150 to $400 including labour and minor materials. Installing a new gas line to an appliance, or running a line for an outdoor kitchen, can climb to $800 to $2,000+ depending on length, wall or floor penetrations, and whether a permit and inspection are needed. Furnace or water heater gas connections tied into a larger install are usually quoted as part of the appliance job rather than separately.

How often does gas piping need to be inspected or serviced?

There's no fixed schedule for gas line inspection unless you're renovating, adding an appliance, or your municipality requires it during a sale. That said, it's worth having a fitter check connections and shutoff valves if you smell gas, notice a furnace or water heater acting up, or haven't had any work done on the system in 10+ years.

Do I need a permit for gas work in Toronto?

Yes, in almost all cases. Any new gas line, appliance connection, or modification to existing piping needs a permit and a TSSA inspection. A legitimate gas fitter will handle the permit application as part of the job. If someone offers to skip this step to save time or money, that's a red flag.

How do I judge the quality of a gas fitting company?

Check that their TSSA certification is current and matches the technician actually coming to your home, not just the company name. Look for clear written quotes, a permit included in the price, and a willingness to answer questions about the specific fittings and shutoffs they're using. Consistent, detailed reviews mentioning follow-through and cleanup are a better signal than a high star average alone.

Gas Fitting in Toronto

Gas fitting covers the installation, repair, and inspection of gas lines and gas-burning appliances: furnaces, water heaters, stoves, BBQ hookups, fireplaces, and outdoor patio heaters. It's one corner of plumbing where you can't shop on price alone. In Ontario, gas work has to be done by someone holding a valid TSSA (Technical Standards and Safety Authority) certification, and the job usually needs a permit and inspection before it's signed off. We've listed 11 gas fitting businesses serving Toronto to help you compare who's actually set up to do this work properly.

What to look for in a gas fitter

Ask to see the technician's TSSA card before work starts, not after. Confirm they'll pull the permit themselves rather than asking you to skip it, since unpermitted gas work can void your home insurance. Get a written quote that separates labour, materials, and permit fees, and ask how they handle a failed inspection. A fitter who explains what they're doing and why, rather than just handing you a bill, is usually the safer bet.

Technicians consistently show up quickly and fix plumbing problems in hours, earning sustained five-star praise for drain, sewer, and emergency repairs.

GTA Restoration Corp.

Water damage and restoration work arrives fast and gets done well; the technical crew impresses consistently. Office handling is the weak link: initial estimates and scope descriptions fail to match final invoices, travel time gets buried in labour charges, and phone staff sometimes push back on customer questions. Communication breakdowns lead to frustration, though the company has shown willingness to negotiate after complaints.

Two five-star reviews praise complex work, fair pricing, and patience; four one-star reviews span five years, all citing missed emergency appointments, no follow-up calls, or rude staff who hung up and blocked customers. Limited positive evidence against consistent failure to show.
