Registered Fuels Contractors are the only businesses that are legally authorized to do fuels related work in Ontario. Find or verify companies with a valid TSSA Registration. Information in this registry does not constitute an endorsement or referral by TSSA. We encourage any person hiring a contractor to choose carefully. For more information, see our Qualified Contractor Checklist.
Note: City/postal code only refers to the location where the contractor has based their main office. It is possible they may offer services in other areas of the province.
This tool is updated at the beginning of each month.
