In Canada, suppliers, employers, and workers use the Workplace Hazardous Materials Information System (WHMIS) to communicate and identify the risks associated with products used in the workplace. WHMIS aligns with the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) used by many countries around the world.

Amendments to the Hazardous Products Regulations (HPR), published in 2022, brought changes to what was previously known as WHMIS 2015. Health Canada allowed a three-year transition period, which ended on December 14, 2025. Everyone who uses WHMIS must now follow the amended HPR, and this course reflects those requirements.

This WHMIS course aims to give you a basic understanding of the system, including general principles, worker safety, and significant updates.
