Estimates for a small start in Canada, not guarantees.

What it is

A small workshop that installs certified compressed natural gas (CNG) or bi-fuel kits in light and medium vehicles, then handles inspection, servicing and cylinder re-testing reminders.

Your first three steps

  1. Speak to your provincial fuel safety regulator about what technician and shop certification you need
  2. Contact certified kit makers about dealer terms, training and approved vehicle lists
  3. Visit local fleets and fuelling station operators to find out who would convert vehicles and where they would refuel
Who pays

Local fleet operators such as delivery firms, taxi and shuttle companies, municipalities and contractors, plus some private owners with high-mileage vehicles.

How it makes money

A fixed price per conversion (kit plus labour), then recurring income from servicing, inspections and cylinder re-certification work.

Skills that help
  • Automotive technician training
  • Careful, safety-first workmanship
  • Talking fleet managers through costs and savings
Watch out for
  • Technician certification and shop authorization differ by province. Check with your provincial regulator (for example Technical Safety BC, or TSSA in Ontario) before installing any kit or trading
  • Check with Transport Canada and Environment and Climate Change Canada whether the kits and conversions you plan to offer are acceptable for the vehicles you will convert, and what that means for vehicle safety and emissions compliance
  • Ask your provincial regulator which installation code and CSA standards it currently applies to natural gas vehicle fuel systems and cylinders, and confirm the current editions yourself
  • Commercial general liability and garage liability insurance that covers fuel system work, which may be costly; confirm cover with a broker
  • Demand depends on nearby CNG fuelling stations, so check access before committing to a lease
  • WCB or WSIB coverage once you hire technicians
