WHMIS stands for the Workplace Hazardous Materials Information System. WHMIS is a comprehensive Canadian hazard communication system that provides health and safety information on hazardous products in Canadian workplaces. This course will help you understand and meet your health and safety responsibilities as a manager or supervisor under WHMIS.

The course reflects the current (amended) WHMIS legislation, familiarizing you with your duties, pictograms and their meanings, product labels, and safety data sheets. Practical advice and guidance on basic health and safety measures are also included so you can take steps to protect your workers and prevent injuries and illnesses. As a manager or supervisor, you need to know your duties, ensure that your workers are trained, label all hazardous products properly, and make sure up-to-date safety data sheets are accessible.

In December 2022, the WHMIS legislation (Hazardous Products Regulations) was amended to align with the 7th revised edition and certain provisions of the 8th revised edition of the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). Workplaces that use, store, or handle hazardous products will need to update their education and training programs to help workers learn and understand the changes to WHMIS. This course reflects the amended legislation and helps to satisfy the education requirements for hazardous products.

The key changes in the December 2022 amendments include:

  • Improved clarity and precision for certain provisions
  • New information elements required on safety data sheets and labels
  • Adoption of a new physical hazard class: Chemicals Under Pressure
  • A change in name of the physical hazard class “Flammable Aerosols” to “Aerosols”
  • A new hazard category for non-flammable aerosols (Aerosols – Category 3)
  • Subcategorization of Flammable Gases – Category 1 into 1A and 1B (with the inclusion of pyrophoric gases and chemically unstable gases in subcategory 1A).

The amended Hazardous Products Regulations (HPR), as of December 2022, is referred to as simply “WHMIS.” Different versions of the Hazardous Products Regulations are referred to as “former” and “amended.” The “former Hazardous Products Regulations” identifies the WHMIS 2015 regulations that were in effect prior to these amendments.

Suppliers will have until December 14, 2025, to bring their safety data sheets and labels into compliance. During this period, regulated parties can choose to comply with either the former HPR or the amended HPR. However, the hazard classification, safety data sheet and label of a hazardous product must be fully compliant with the version of the regulation chosen. A product classified in accordance with the amended WHMIS will not be compliant if the safety data sheet is compliant with the former WHMIS 2015.
