Dangerous Goods Harmonization Under the Ontario Fire Code

Effective January 1, 2026, the Ontario Fire Code (OFC) introduces several updates to better harmonize dangerous goods requirements with the National Fire Code of Canada (NFC). These changes are part of a broader effort to improve consistency, clarity, and enforcement across jurisdictions.
A key update is the introduction of new OFC Subsections 3.2.5. and 3.2.7., which specifically address the indoor storage of dangerous goods and aerosol products. These provisions align Ontario more closely with national standards and provide clearer direction for building owners, operators, and authorities having jurisdiction.

The updated requirements address items such as:

  • Maximum permitted quantities of dangerous goods and aerosols,
  • Separation and compatibility requirements, and
  • Administrative controls, including documentation and procedural expectations.

Why This Matters

The Ontario Fire Code is retroactive, meaning these requirements apply not only to new construction, but also to existing buildings and ongoing operations. This makes proactive review essential, even if no recent changes have been made to a facility.

Owners and operators should take this opportunity to review:

  • Dangerous goods storage practices,
  • Fire safety plans and emergency procedures,
  • Labeling and identification of dangerous goods, and
  • Internal administrative controls related to hazardous materials.
Early alignment with the updated OFC requirements can reduce compliance risk, support safer operations, and minimize surprises during inspections or enforcement activities.
