The Technical Standards and Safety Authority (TSSA) carries out inspections and licensing for new or existing fuels equipment and facilities.

The Technical Standards and Safety Authority (TSSA) carries out inspections and licensing for new or existing:  

  • Pipelines

  • Gas stations

  • Marinas

  • Bulk plants

  • Compressed natural gas (CNG) or propane fueling stations/propane used in vehicles

  • Tanker trucks that dispense, transmit, distribute or transport gasoline-related products, compressed natural gas or propane

  • Propane dispensing facilities and propane cylinder exchange sites

New facilities are inspected before they are licensed. Existing facilities are inspected periodically according to a risk-based model.  

TSSA’s Fuels Inspection Team also:

  • Investigates incidents or reports of non-compliance at these facilities, provides fuels approvals, and registers and audits contractors

  • Ensures that equipment and appliances associated with the transportation, usage, and handling of oil and gas comply with Ontario’s laws.

Equipment approvals

New equipment must be approved to a recognized standard by a testing agency. A Field Approval (pdf) from TSSA is required for equipment that has not been certified. Registered contractors must perform all work on fuel equipment at licensed sites.   

TSSA also periodically performs inspections of repaired equipment and its associated piping to ensure that the equipment remains in compliance with the initial approval and is operating within current codes and standards.  


TSSA orders appropriate corrective actions when a device or equipment is found to be non-compliant. Orders to shut down a device or facility until compliance is met may also be issued. The person responsible for the non-compliance will be invoiced for the cost of this inspection.  

Incident investigation 

If an incident such as a fire, explosion, carbon monoxide poisoning, fuel leak or spill occurs, the incident must be reported to TSSA’s Fuels Safety Division immediately. TSSA will then conduct an investigation.

Tampering with the scene, except to save property or ensure safety, is not permitted. Learn more about reporting an incident.
