Should Ontario Update Its Fuel Oil Safety Codes?

Official title: Amendments to Fuel Oil Code Adoption Document (CAD) 2025

Open Regulations & Permits Health & Safety Housing & Communities
Ontario's safety regulator wants to adopt the 2024 national safety codes for fuel oil equipment. This affects furnaces, boilers, and oil-burning appliances in homes and businesses. The update would also fold in requirements from a separate approval code that's being retired.

Why This Matters

Heat your home with oil? This affects the equipment standards your furnace must meet. Contractors installing or servicing oil equipment will need to follow updated rules. The changes also require professional engineers to sign off on certain calculations—potentially affecting installation costs.

What Could Change

Ontario would adopt the 2024 CSA B139 series codes for fuel oil equipment. Seven existing Ontario-specific amendments would be removed, while three new ones would be added. Certain calculations for fuel source conversions and installations would now require a professional engineer's approval.

Key Issues

  • Should Ontario adopt the 2024 edition of CSA B139 series fuel oil safety codes?
  • Should requirements from the Field Approval Code be incorporated into the Fuel Oil CAD?
  • Should professional engineer approval be required for certain fuel conversion and installation calculations?
