Gas Appliance & Fuel Safety Compliance in London, ON
If you own or manage property in London, gas appliance and fuel safety compliance is one of those obligations that stays invisible right up until an inspector, insurer or buyer makes it urgent.
Natural gas and propane systems operate under provincial fuel-safety law — TSSA in Ontario, Technical Safety BC, provincial branches across the country — which licenses every person who may legally touch them and sets the codes (CSA B149 series) their work must meet. For property owners the practical exposures are unlicensed past work, aging venting, and the carbon monoxide file that criminal negligence cases are made of.
How it works in Ontario
The rules that govern this in Ontario flow from the Ontario Building Code (O. Reg. 332/12), and your paperwork ultimately answers to Technical Standards and Safety Authority (TSSA) — our local partners work with them constantly.
Gas Appliance & Fuel Safety Compliance for London properties
What makes London specific: the Residential Rental Units Licence has required licensing of smaller rental buildings since 2011 — one of Ontario’s longest-running rental licensing regimes — with fire and building inspections tied to renewal.
Most London requests reach us from one of four directions: a transaction, an insurer condition, a municipal letter, or a board meeting where someone finally asked when this was last done.
Where owners get exposed
Handyman-installed gas lines to garages and BBQs, converted appliances without proper orifices, corrugated stainless tubing without bonding, and orphaned water heaters venting into oversized chimneys after furnace upgrades — all common, all findable by a licensed technician in an hour, all the kind of finding that voids insurance when discovered post-loss instead.
The process
The path from enquiry to closed file usually looks like this:
- Describe the appliances and any known unlicensed history.
- A licensed gas technician inspects systems end-to-end including venting and CO.
- Deficiencies are corrected under proper tags/permits.
- CO alarm compliance is verified against your province’s rules.
- Records establish the maintenance file for insurer and tribunal purposes.

Frequently asked questions
Are CO alarms actually required?
In most provinces, yes — near sleeping areas in homes with fuel-burning appliances, fireplaces or attached garages. Requirements extend to rental units, where they are the landlord’s obligation.
How often should gas appliances be serviced?
Annually, by licensed technicians, with records — the interval every manufacturer, insurer and authority converges on. Venting and heat-exchanger condition are the life-safety items in that visit.
Which authority handles this in London?
Day to day, enforcement in London runs through the municipal officials (building, fire prevention, by-law) with Technical Standards and Safety Authority (TSSA) as the provincial authority behind them under the Ontario Building Code (O. Reg. 332/12). Our local partners deal with both routinely.
