Underground Fuel Oil Storage Tanks

Here's a list of common questions homeowners have regarding underground storage tanks:

Q :Why do I have to register my underground tank?
A : Under Ontario Regulation 213/01 (The Fuel Oil Regulation), it is mandatory that all underground (buried) fuel oil tanks be registered with TSSA.

Reference: Ontario Regulation 213/01 "Fuel Oil", Section 7. (4)

Additional Information:
  • "No person shall supply fuel oil to an underground tank unless the underground tank is registered." Ontario Regulation 213/01 "Fuel Oil", Section 7. (4).
  • These regulations help to protect Ontario's environment from possible fuel oil leaks. Creating a registry of the location and age of each underground tank in the province ensures that fuel oil tanks that are in danger of leaking do not continue to receive fuel oil.
  • By registering the tank, TSSA will be able to keep track of the location and condition of underground fuel oil tanks in Ontario.

Q :How do I register my underground storage tank?
A : You need to complete and submit an
Application for an Ontario Registration to Operate / Install an Underground Fuel Oil Tank (I.D. FS 09143) (Download) to TSSA. Following the processing of your application for registration of your underground (buried) fuel oil tank you will receive written notification that your tank is registered with TSSA, with its own unique registration number.

When you receive this registration number, you are required to quote it to your fuel oil distributor. This will prevent potential disruptions with your fuel oil service delivery.

Additional Information:
  • TSSA has advised fuel oil distributors that unregistered tanks are to be considered non-immediate hazards and fuel should be provided to clients and notice given to them to obtain a registration number within a timeframe not exceeding 90 days.
Reference: Ontario Regulation, 213/01 "Fuel Oil", Section 24.


Q :Is there a cost associated with registering my underground storage tank?
A : No there is not. This service is free of charge.

TSSA will provide the Application form (

Q :I no longer use my underground storage tank. can I leave it in place and not remove it?
A : If you are thinking of abandoning your fuel oil underground storage tank, you are required to submit an application for a Variance to TSSA. Upon receipt of your Variance Application, it will be reviewed and soon after (approximately 21 business days) you will receive written notification informing you of the outcome of your variance application.

Additional Information:
  • The Variance Process will determine whether:
    1. The tank must be removed.
    2. It can remain in place, with conditions.

  • Variance Application Forms and Abandonment Information Sheets are available on our website.

Q :How can I tell if my underground tank is leaking?
A : If your oil consumption suddenly goes up, your tank may have sprung a large leak. If this is the case, contact the Spills Action Centre of the Ministry of Environment and Energy at 1-800-268-6060.

Additional Information:
  • Because underground fuel oil storage tanks are buried, it is difficult to tell whether the tank is leaking or not. Some underground tanks may leak for years without the tank's owner realizing it.
  • Tanks over 5000 liters need to be leak tested annually.
Reference: CAN/CSA-B139-00 "Installation Code for Oil Burning Equipment".
