Fuel Oil

Per legislation, applicable regulations, codes, and standards, the Technical Standards and Safety Authority (TSSA) regulates fuel oil in Ontario.

Navigate this section

In accordance with the Technical Standards and Safety Act, 2000 and other applicable regulations, codes, and standards, the Technical Standards and Safety Authority's (TSSA) Fuels Safety Program regulates Fuel Oil in Ontario. 

TSSA has adopted the Fuel Oil Code (FOC) also known as CSA B139 Series: 19 (CSAGroup.org); and Fuel Oil CAD Amendment (2021, pdf) as well as CSA B138.1 and B138.2 (2017 edition, CSAGroup.org) in relation to portable generators. The Fuel Oil CAD (pdf) is adopted by reference in Ontario Regulation 213/01: Fuel Oil. 

O. Reg. 213/01 applies to:

TSSA registers qualified fuel contractors and inspectors in accordance with fuels industry standards in Ontario.

TSSA also provides services related to heating fuels for those in the fuels industry. These services, including variance approvals, equipment field approvals, and consultations, ensure that industry members operate safely and meet legislative and regulatory standards.

By law, all contractors working on fuel oil equipment, such as underground tanks, must be registered with TSSA. 

Persons repairing, installing, removing, and servicing fuel oil underground tanks must also be trained and certified. Please see Ontario Regulation 215/01: Fuel Industry Certificates and all associated regulations.

Fuel Oil Distributor

A fuel oil distributor is a person who supplies fuel oil to an end user.

In Ontario, a licence is required to distribute fuel oil through a central oil-distribution system or facility.

TSSA enforces guidelines for fuel oil distributors in Ontario. According to O. Reg. 213/01, a licence to distribute fuel oil is valid for 12 months. An application to renew the licence must be made before it expires. The licence holder must post the licence at the location for which it is issued so that it is readily visible.

For more details on the requirements for distributing fuel oil, refer to O. Reg. 213/01: Fuel Oil.

Fuel Oil Distributor Audit Program

To enhance oversight of the risks associated with fuel oil tanks, TSSA introduced a Fuel Oil Distributor Audit Program in 2020.  Under this program, distributors must demonstrate their compliance with O. Reg. 213/01 by meeting the following six primary requirements: 

    1. Initial and Periodic Inspections

    2. Underground Tank Registrations

    3. Supply to a Compliant Site

    4. Employees’ Certification and Compliance

    5. Incident Reporting

    6. Identification, Action as Required and Reporting of non-compliances (unacceptable conditions)

TSSA’s audit will require distributors to demonstrate compliance through their processes and records.

Regarding the first requirement listed above “Initial and Periodic Inspections”, if there is no process to verify distributor inspections, TSSA will now do a field verification. If TSSA does a field verification and non-compliances are found, orders will be issued to address the specific non-compliances including the following “as a person who supplies fuel to containers and tank systems, you are hereby ordered to develop a program whereby you can demonstrate that you have taken every precaution that is reasonable to ensure the inspections required by 7(1) of Ontario Regulation 213/01 (Fuel Oil) are accurate”.

Unacceptable Conditions

Under O. Reg 213/01, certain regulated parties are required to notify the Authority to Have Jurisdiction (AHJ) (which is defined as TSSA under the adopted Code), under certain circumstances if there is an unacceptable condition, including:

Distributors

  • Section 23 (1)(e) requires a distributor to forward a copy of a red tag (immediate hazard) they issue to the AHJ, being TSSA.
  • Section 24(1)(d) requires a distributor to forward a copy of a red tag (no immediate hazard) to the AHJ, being TSSA.

Contractors and Certificate Holders

  • Section 25 (1)(g) requires certificate holder or contractor who issues a red tag (immediate hazard) to send a copy of that notice to the AHJ (TSSA).

  • Section 26 (1)(e) requires a certificate holder or contractor to send a copy of a red tag (non-immediate hazard) to the AHJ (TSSA).

Note: Please report any unacceptable conditions for Fuel Oil by email at fueloilhazard@tssa.org. 

Storage tanks

Improper fuel storage and handling in aboveground and underground storage tanks can negatively impact the environment. Regulations apply to specific types of storage tanks. 

By law, all contractors working on fuel oil equipment, such as underground tanks, must be registered with the TSSA.

Persons repairing, installing, removing, and servicing fuel oil underground tanks must also be trained and certified as a Petroleum Equipment Mechanic 2 (pdf). 

Please see Ontario Regulation 215/01: Fuel Industry Certificates and all associated regulations.

Aboveground fuel oil storage tanks

An aboveground tank is one installed at or above grade level within a building or a secondary containment. This definition does not include a tank in direct contact with backfill material.

Ontario regulatory bodies prefer using aboveground fuel oil storage tanks as they are easier to inspect, reducing the risk of spills and increasing the likelihood of leak detection.

Underground fuel oil storage tanks

An underground oil tank is a container that is buried and contains fuel oil to be used in appliances such as furnaces and boilers. Tanks located in basements are not considered underground tanks.
