The Technical Standards and Safety Authority (TSSA) has published the amendments to the Fuel Oil Code Adoption Document (CAD) and the associated Consultation Summary, following a review of feedback received during the consultation that closed on December 19, 2025.
We thank stakeholders for their input on the Fuel Oil CAD, which was last updated and published in 2021.
Please read the amendments to the Fuel Oil CAD and the associated Consultation Summary.
Thank you for attending the Operating Engineer (OE) Compliance Standards webinar on March 26, 2026. Here is a recording of the webinar.
The purpose of the webinar was to give attendees an opportunity to learn how the OE Compliance Standard was developed, the difference between high-risk non-compliances on the OE Compliance Standard and other non-compliances, and the process to follow when non-compliances are found during a periodic inspection.
We hope those who attended the webinar have a better understanding of how the OE Compliance Standard will enhance the safety of power plants in Ontario. Please visit our website for more information about the Operating Engineer Compliance Standard that is coming soon.

The Technical Standards and Safety Authority (TSSA) is seeking your comments on a proposal to license operations conducting retail mobile fueling under Ontario Regulation 217/01, Liquid Fuels and Liquid Fuels Handling Code.
Retail mobile fueling is defined as the dispensing of fuel from a highway tank to a licensed vehicle or a watercraft that cannot be fueled at a marina. A prior consultation was conducted on the technical requirements for retail mobile fueling facilities.
The opportunity to comment on a TSSA proposal to license retail mobile fueling operations is open for 30 days from January 30, 2026, to March 1, 2026. Please visit EngageTSSA to provide your feedback.
If you have questions or concerns, please contact Chris Thompson at cthompson@tssa.org.

Starting January 1, 2026, manufacturers submitting registration for fittings used in pressure-retaining systems to the Technical Standards and Safety Authority will be required to use the new Declaration of Conformity form.
The current Statutory Declaration form used to register fittings that operate at pressure exceeding 15 psi will no longer be accepted after this date. This change is mandated by the CSA B51 (2024 Edition) Boilers and Pressure Vessels Code published by the Canadian Standards Association.
If you have any questions about this new requirement or need assistance with the updated process, please contact bpv_reg_billing@tssa.org for support.
This news item was sent to manufacturers who have submitted fitting registrations to TSSA and boiler and pressure web subscribers.
The revocation of the regulatory exemption on agricultural boilers and pressure vessels (BPVs) in July 2021 means that all repairs and alterations of BPVs, fittings and piping used for agricultural purposes must comply with Ontario Regulation 220/01: Boilers and Pressure Vessels under the Technical Standards and Safety Act, 2000.
Please advise your clients who own and operate agricultural BPVs to report existing equipment by completing the form here.
When clients are requesting work on BPVs and piping, please handle these requests according to the process for regulated devices, which includes the following:
- Contractors performing work on BPVs (for example, fabricators, contractors, assemblers or repair organizations of pressure equipment) must hold a valid Certificate of Authorization for the scope of activities.
- BPVs installed after July 1, 2021, must have a Canadian Registration Number (CRN).
- New piping or additions to existing piping systems require design registration and inspection. Please see guidelines for pressure piping registration for details and review the application forms and instructions for applying electronically.
For more information, please see the requirements for existing agricultural BPVs that need repair, alteration, upgrading or replacement or visit Agricultural Operations – Boilers and Pressure Equipment.
Questions can be directed to agriculture.bpv@tssa.org.

TSSA is planning to enforce requirements to ensure the safety of retail mobile fueling, or dispensing fuel from a highway tank to a licensed vehicle or a watercraft that cannot be fueled at a marina.
Please visit EngageTSSA to provide your comments on retail mobile fueling requirements drafted by the working group revising the Liquid Fuels Handling Code.
The opportunity to provide feedback will be open until December 3, 2025.

The fees for Certificates of Inspection (COI) charged to boiler and pressure vessel (BPV) owner and operators will change starting on January 2, 2026. Technical Standards and Safety Authority (TSSA) is increasing BPV COI fees to ensure the continued regulatory effectiveness of the BPV program and safety in the BPV industry.
New Fee Structure
Why the Increase?
As a not-for-profit regulator, TSSA is mandated under the Technical Standards and Safety Act, 2000, to deliver its safety mandate and recover all direct and indirect costs from the industries it regulates. In 2018, Ontario’s Auditor General noted that TSSA was not adequately meeting this obligation.
Since 2018, TSSA has gradually introduced fee increases across all its regulated sectors. TSSA has kept fee increases below the cumulative inflation rate and at cost recovery, except for the BPV COI program, which has been operating at a deficit since the program began.
In 2023, TSSA opted to delay a fee increase for BPV COIs to focus on expanding the BPV inventory base ─ following up on BPVs with lapsed COIs, reviewing insurer data to identify unlicensed devices, and evaluating agriculture BPVs that were previously exempt.
Current BPV Fees (May 1, 2025)
Why This Matters
Continuing to operate the BPV COI program at a deficit is unsustainable. It poses a public safety risk and limits TSSA’s ability to deliver its safety mandate.
To eliminate the projected deficit and achieve cost recovery, the fees have been recalculated using an up-to-date BPV inventory count. They reflect efficiency gains from modernized information technology systems, optimizing operational efficiencies and improved data accuracy. These changes will help ensure the program is fully supported and sustainable.
Our Commitment
We remain committed to safety and efficiency. Over the past five years, serious injuries and fatalities in TSSA-regulated sectors have declined, and we continue to focus on improving both safety and client experience in Ontario.
