Quick answer
A licensed gas fitter in New Westminster holds Technical Safety BC certification to connect, install, and service natural gas appliances such as water heaters and boilers, with training covering combustion safety, venting, gas piping, and the BC Gas Safety Regulation. The City of New Westminster requires a permit and independent inspection for most gas installation and replacement work. CANRO holds gas licence LGA0043870 and boiler licence LBP0046450 and handles the permit process as part of the job.

Gas fitter certification in BC is issued in classes by Technical Safety BC, and residential water heater and boiler work typically falls under Class A or Class B gas fitting depending on scope. Passing those exams means demonstrating competence in combustion analysis, correct venting design for the appliance type, gas pressure and pipe sizing, and code compliance under the provincial Gas Safety Regulation — not just familiarity with a specific brand of appliance.
It is entirely reasonable to ask a contractor for their individual technician's licence number before work begins, not just a company name. If you want independent confirmation, Technical Safety BC can verify an active licence directly.
The City of New Westminster requires a permit for the situations above, and the inspection that follows checks clearance to combustibles, vent termination location, gas line sizing, and shutoff accessibility. A licensed fitter working in the city should handle the permit application and schedule the inspection as part of the job rather than leaving it to the homeowner to sort out.
New Westminster has one of the older housing stocks in Metro Vancouver, with a large concentration of character homes in Queens Park and the Brow of the Hill dating back many decades, alongside newer townhome and condo development closer to the Fraser River. In the older homes, it is common to find a water heater that shares, or used to share, a chimney flue with a furnace that has since been upgraded to a high-efficiency, sidewall-vented unit. That leaves the water heater venting alone into an oversized flue, which can cause poor draft — exactly the kind of condition a licensed fitter checks for during any service call or replacement quote.
Steep hillside streets in parts of the city also mean some mechanical rooms sit at grade on a daylight basement level with an exterior wall exposed to weather, which affects vent termination clearances and, in colder snaps, freeze exposure on exterior piping.
| Question | Why It Matters |
|---|---|
| What is your Technical Safety BC gas licence number? | Confirms legal authority to perform the work |
| Will you pull the New Westminster gas permit? | Ensures independent inspection sign-off |
| Is my water heater currently orphaned after a furnace upgrade? | Affects draft safety and may require a liner or reconfiguration |
| What venting does a replacement require? | Changes both cost and clearance requirements |
| What is the ballpark cost range? | Sets expectations before the in-home assessment |
As a ballpark, not a quote: boiler install roughly $6,500 to $14,000 or more, boiler replacement roughly $7,500 to $15,000 or more, and tankless water heater install roughly $3,500 to $7,500, with venting changes and gas line work moving the final number in either direction.
Safety note
If you ever smell gas, hear hissing near a gas line, or suspect a venting or carbon monoxide problem, leave the home immediately and call FortisBC at 1-800-663-9911 from a safe location before doing anything else. Do not attempt to relight a pilot or reset a gas appliance yourself if you cannot identify the cause of the problem; wait for a Technical Safety BC licensed gas fitter.
No. Gas fitting is a separate certification from plumbing in BC. Any work on the gas connection, venting, or combustion components of a water heater or boiler requires a Technical Safety BC gas fitter licence specifically.
It depends on the scope. A true like-for-like replacement on an existing line sometimes still needs a permit; confirm with your licensed fitter rather than assuming it is exempt.
It means the water heater used to share a flue with a furnace that has since been replaced with a sidewall-vented unit, leaving the water heater venting alone into an oversized chimney. This can cause poor draft and is worth having assessed.
Ask for the individual's licence number directly and, if you want extra confidence, contact Technical Safety BC to confirm it is active and in good standing.
It varies by scheduling and time of year. A licensed fitter who regularly works in the city will typically be able to give you a realistic estimate based on recent jobs.
