- Pipelines
- Gas stations
- Marinas
- Bulk plants
- Compressed natural gas (CNG) or propane fuelling stations
- Tanker trucks that dispense, transmit, distribute or transport gasoline-related products, compressed natural gas or propane
The TSSA also provides special approvals, audits registered contractors and investigates incidents and reports of non-compliance.
Schedule an inspection
To book an inspection, please call toll-free (outside Ontario) 1-877-682-8772 or view our inspector directory.
Arrangements for "rush" or "last-minute" inspections are possible however special fee considerations apply. Inspector availability depends on their individual schedules.
Types of inspections
TSSA inspectors carry out inspections and licensing for the following:
- New or existing gas stations, marinas, bulk plants, compressed natural gas (CNG) or propane fuelling stations and tanker trucks that utilize gasoline-related products
Compressed natural gas or propane used in vehicles.
Propane dispensing facilities and propane cylinder exchange sites
New facility inspections are conducted before licensing. Existing facilities are also inspected on a periodic basis. Inspection frequency is determined using a risk-based model.
Contractors who work on these facilities are also registered through the TSSA and are periodically audited. Our Fuels Inspection Team also investigates incidents or reports of non-compliance at these facilities.
Below are details about the types of inspections the TSSA conducts.
Fuels for heating |
| Fuels like natural gas and heating oil are part of our everyday life. They keep our homes warm in the winter through appliances like gas furnaces or fireplaces. It's our job to ensure that equipment and appliances associated with the transportation, usage and handling of these fuels comply with Ontario's laws. We also work with industry groups to help raise public awareness about fuels safety, specifically to educate the public about the risk of carbon monoxide poisoning. |
Fuels for transportation |
|
Could you imagine life without vehicles? Thanks to fuels like gasoline and diesel that make them run, getting from point A to B is a whole lot easier. |
New equipment |
|
New equipment must be approved to a recognized standard by a testing agency. Where equipment has not been certified, we provide a Field Approval of the device. Please note that registered contractors must perform all work on fuel equipment done at licensed sites [HYPERLINK TO: Fuels>Applications, Forms and Fees>Obtain a Facility Licence page]. |
Existing equipment |
| The certificate holder provides inspections of repaired equipment and its associated piping, etc. TSSA periodically performs inspections to ensure that equipment remains in compliance with the initial approval and is being operated within current codes and standards. |
Non-compliance |
| Where any non-compliance is discovered, TSSA orders appropriate corrective actions to be implemented, and in worst-case scenarios, orders a device or facility to stop operating until the compliance is met. The person responsible for the non-compliance will be invoiced the cost of this inspection. |
Incident investigation |
|
If an incident such as a fire, explosion, carbon monoxide poisoning, fuel leak or spill occurs, it must be reported to TSSA's Fuels Safety Division immediately in order for an investigation to be conducted. Tampering with the scene, except to save property or ensure safety, is not permitted. View our Report an Incident page for more information. |
