A gas fitter is one of those trades homeowners don’t think about until they need one — running a new line for a BBQ, converting a wood fireplace to gas, or connecting a generator. It’s specialized, licensed work in Ontario, and not something a general contractor or handyman is legally allowed to take on, because the margin for error with gas lines is a lot smaller than with most home projects.
A properly done gas installation involves more than connecting a pipe. It means sizing the line correctly for the appliance’s BTU rating, pressure-testing it before it’s used, and pulling the permit and inspection that make the work both legal and covered by insurance if something goes wrong later. Skipping any of those steps is how small mistakes turn into real safety problems.
NexGen Heating & Cooling Corp. bundles gas fitting into its regular HVAC service across Newmarket, so a homeowner dealing with a furnace issue and wanting a gas line run for a new fireplace insert doesn’t need to coordinate two separate contractors. That matters because RenovationFind has actually verified NexGen’s licensing, insurance, and legal standing — a level of confirmation worth more here than on almost any other home service, since gas work is one of the few trades where hiring the wrong company creates a genuine safety risk, not just a quality-of-work problem. Technicians walk through the scope of a gas job before starting, including what the permit and inspection process will look like.

2. ALP Heating Ltd.
ALP Heating runs a dedicated Newmarket gas line installation page on its site, which reflects how much of the company’s business in the area is specifically gas work rather than general HVAC with gas as an occasional add-on. Their TSSA-licensed technicians handle everything from a straightforward BBQ hookup to underground extensions for pizza ovens and custom fire features, and the company has picked up multiple HomeStars “Best of” awards since launching in 2019. For Newmarket homeowners comparing quotes, a company that treats gas fitting as its core specialty tends to move faster from initial call to completed installation than one where it’s a secondary service.
Key Services & Features
– Dedicated Newmarket gas line installation service
– Underground extensions for BBQs, pizza ovens, and fire features
– TSSA-licensed gas fitting as a core specialty
– Same or next-day service on many jobs
– Transparent, itemized quotes
– Multiple HomeStars “Best of” award wins
3. Canco ClimateCare
Canco ClimateCare has run its Gorham Street shop in Newmarket since 1984, and gas fireplace work is a specific, named part of their service list rather than something bundled vaguely into “heating.” Before a fireplace installation, their team visits the home to work out routing and cost rather than quoting sight-unseen, which matters on a job where the gas line has to be run to a specific spot rather than an existing hookup. Because their technicians are direct employees rather than subcontractors, the person who ran the initial assessment is typically the one accountable for how the installation turns out.
Key Services & Features
– Gas fireplace line installation and service
– In-home assessment before quoting fireplace or gas line work
– In-house technicians, not subcontracted
– Gas line runs for pool heaters and other outdoor appliances
– 100% performance guarantee on installation work
– Based in Newmarket since 1984
4. Martino HVAC
Martino HVAC runs a fireplace showroom with more than 30 Napoleon, Kingsman, and Dimplex models on display, which puts them a step beyond most HVAC companies that treat gas fireplaces as an occasional job. That showroom background carries into their gas fitting work more broadly — dryer hookups, BBQ lines, stove and cooktop connections, and gas leak repair — since a company selling and installing fireplaces at that scale needs the gas fitting infrastructure to match. Since 1987, the business has built out its gas services alongside its core HVAC work rather than treating one as secondary to the other.
Key Services & Features
– Gas fireplace sales and installation, with a dedicated showroom
– Gas line installation for BBQs, dryers, and stoves
– Gas leak detection and repair
– TSSA-licensed gas fitting since 1987
– Napoleon, Kingsman, and Dimplex fireplace dealer
– Serving Newmarket and the surrounding region
5. Summers & Smith Cooling & Heating
Summers & Smith has operated out of Aurora since 1973 and lists fireplace installation and service as one of its distinct offerings for Newmarket and the surrounding communities, alongside its core furnace and AC work. Fifty years in York Region means the company has had time to build a full-service model rather than staying narrowly focused on one system, and gas fitting for fireplaces fits into that broader approach. Homeowners looking to convert a wood-burning fireplace to gas, or add a new gas insert, deal with a company that quotes the job after an actual site visit rather than a phone estimate.
Key Services & Features
– Gas fireplace installation and service
– Gas line work for furnaces and other appliances
– In-home assessment before quoting
– In-house technicians for residential and commercial work
– Serving Newmarket and York Region since 1973
– Authorized Lennox and Daikin dealer
What Services Do Newmarket Gas Fitters Offer?

– Gas leak detection and emergency repair
– Gas valve replacement and venting inspection
– Permit filing and TSSA inspection coordination
– Gas fireplace installation and wood-to-gas conversion

– Gas dryer, stove, and generator hookups

Newmarket’s older homes near the historic downtown core often have gas lines installed decades ago that may need tracing or upgrading before a new appliance can be added, while newer subdivisions further out are more likely to have modern gas infrastructure already in place but homeowners wanting to extend it outdoors. Winters in this part of York Region put real, sustained demand on gas furnaces and gas fireplaces for months at a time, which makes correct installation and periodic inspection more than a one-time formality. A gas fitter with experience across both older and newer Newmarket housing stock has usually already worked through the specific routing challenges each presents.
How Much Does Gas Fitting Cost in Newmarket?
Newmarket-specific gas fitting pricing wasn’t available from a confirmed local source, so the ranges below reflect broader GTA data instead. Treat these as a starting point rather than a confirmed local quote.
| Project |
Typical Cost Range |
| Quick-connect BBQ hookup (existing capped line) |
$150 – $650 |
| Permanent BBQ gas line installation |
$1,500 – $2,500 |
| Gas fireplace line installation |
$500 – $1,200 |
| Full gas fireplace installation (unit + venting + labour) |
$4,500 – $10,000+ |
| Gas stove line |
$450 – $900 |
| Gas dryer line |
$400 – $800 |
| Generator hookup |
$800 – $2,000 |
| Pool heater gas line |
$700 – $1,400 |
TSSA-licensed gas fitter labour generally runs $150 to $250 an hour, with permit fees adding another $100 to $300 — most contractors fold both into the quoted price, but confirm that directly if it isn’t spelled out. Distance and routing complexity drive most of the variation in a given job: a short, direct run costs far less than one that has to go underground or through finished walls. For anything beyond a simple appliance hookup, get at least three itemized quotes before committing.
How to Hire a Gas Fitter in Newmarket
- Confirm TSSA licensing before booking. This is a legal requirement in Ontario, not a nice-to-have, and a legitimate company will confirm it without hesitation.
- Be specific about the job when you call. A fireplace conversion, a BBQ hookup, and a suspected leak all require different urgency and scope.
- Ask if the permit and TSSA inspection are included in the quote. Some contractors bundle it in, others don’t — know which before agreeing to a price.
- Get the routing plan in writing for anything beyond a basic hookup. How the line travels affects both cost and how much disruption to expect.
- Confirm the line will be pressure-tested. This is a standard safety step for new gas work, and a company that skips mentioning it is worth a follow-up question.
- Treat a suspected gas leak as an emergency, not a quote request. Leave the home and call from outside if you smell gas.
Questions to Ask Before Hiring
Are you TSSA licensed to do gas fitting work in Ontario?
This is a legal requirement, and a company that hesitates to answer directly shouldn’t be doing the work. You can look up authorized heating fuel contractors on the TSSA website.
Is the permit and inspection included in your quote?
Practice varies by company — confirm this upfront so there’s no surprise on the final invoice.
Will you pressure-test the line before it’s used?
This is a basic safety step, and it’s worth confirming a company does it as standard practice, not an optional add-on.
How will the gas line be routed, and what happens to the wall or yard afterward?
Ask how the company plans to restore the area once the line is in, especially for anything running through finished space.
Do you offer emergency service for a suspected leak?
Even for a planned installation, it’s worth knowing whether the company can respond quickly if something goes wrong down the road.
Frequently Asked Questions
How much does gas line installation cost in Newmarket?
Most gas line jobs fall between $400 and $2,500, depending on the appliance and how far the line has to run — a simple BBQ hookup sits at the lower end, while a full outdoor gas line installation runs higher.
Do I need a permit for gas line work in Newmarket?
Yes. Gas fitting requires a permit and TSSA inspection, and a licensed gas fitter typically coordinates this as part of the job.
Can my regular HVAC company install a gas line, or do I need a specialist?
The work must be done by a TSSA-licensed gas technician. Many HVAC companies employ licensed gas fitters on staff, so the licence matters more than whether the company specializes narrowly in gas.
What should I do if I smell gas in my home?
Leave immediately, avoid light switches or anything that could spark, and call your gas utility’s emergency line or 911 from outside. Contact a gas fitter for repair once the immediate danger has been addressed, not during an active leak.
How long does gas fireplace installation take?
A straightforward gas line for an existing hookup can take a couple of hours. A full fireplace conversion, including venting and finishing work, often takes a full day or more.
Is it worth converting a wood fireplace to gas?
Many homeowners do it for convenience — gas fireplaces start instantly and don’t require the same cleanup as wood — but it requires a proper gas line, venting changes, and permit work, so get a full quote before assuming it’s a simple swap.
Choosing a Gas Fitter in Newmarket
Gas fitting carries more built-in risk than most home services, since improperly installed lines create real fire and carbon monoxide hazards rather than just a quality-of-work issue. Licensing, insurance, and a genuine safety-first approach matter more here than almost anywhere else in home improvement.
