WHMIS 2025 Online Course and Certification

Whether you work on a construction site, manage a healthcare clinic, oversee a manufacturing plant, or handle everyday cleaning supplies in an office, chemical safety is a fundamental part of Canadian workplace health and safety.

For decades, the Workplace Hazardous Materials Information System (WHMIS) has served as Canada’s national hazard communication standard. It ensures that workers who manufacture, handle, store, or dispose of hazardous products have the vital safety information they need.

However, chemical safety isn’t static—it evolves to match global standards and scientific advancements. In late 2022, Health Canada published significant amendments to the Hazardous Products Regulations (HPR). Health Canada established a multi-year implementation schedule with a final deadline of December 2025 to allow businesses and workers time to adapt.

Understanding WHMIS 2025 is no longer optional—it is a critical requirement for regulatory compliance and workplace safety across Canada. This article discusses WHMIS 2025 and what you need to know.

WHMIS 2025 and Why Did It Change?

WHMIS originally aligned with the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) back in 2015. Since then, international standards have continued to improve to make hazard communication more precise, transparent, and user-friendly.

Health Canada updated the HPR to align with newer building blocks of the GHS (specifically GHS Revision 7 and select elements of Revision 8). These amendments redefine workplace chemical classifications and transform how labels and SDS sheets display hazard information.

Key Updates Introduced in WHMIS 2025:

New and Revised Hazard Classes: The updated system introduces new subcategories and hazard classes, such as Chemicals Under Pressure, Flammable Gases, and Non-Flammable Aerosols.

Clearer Hazard Definitions: Requirements around physical and health hazard classifications—including skin corrosion, eye irritation, and biohazardous infectious materials—have been refined to clarify hazard identification.

Updated Safety Data Sheets (SDSs): Standardized 16-section SDSs now require more specific information regarding chemical properties, ingredient concentrations, and toxicity data.

Modernized Labelling Requirements: Workplace and supplier labels must reflect updated hazard statements, precautionary statements, and standardized pictograms.

Why Is Updated WHMIS Training Mandatory?

Occupational Health and Safety (OHS) legislation in every Canadian province and territory mandates that employers provide WHMIS education and training to any employee who works with, or is likely to be exposed to, a hazardous product.

Because WHMIS 2025 updates how hazardous products are classified and labelled, legacy WHMIS 2015 training may leave workers unable to recognize updated supplier labels or correctly interpret newly formatted Safety Data Sheets.

For employers, ensuring your team completes updated training protects your business from non-compliance penalties during OHS inspections. More importantly, for workers, proper training prevents costly mistakes, chemical exposure, fires, and workplace injuries.
