Product Description

WHMIS is changing. The essential elements of the Workplace Hazardous Materials Information System (WHMIS) such as labels, safety data sheets (MSDSs/SDSs) and training will remain. However, soon WHMIS will be adopting international classification and labelling rules as developed by the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). This WHMIS After GHS: Preparing for Change publication will help guide you through the anticipated changes due to the adoption of these new rules. It will help your organization understand the new requirements and help make a successful transition to “WHMIS After GHS”.


The WHMIS After GHS: Preparing for Change publication will

  • Provide an overview of the new Globally Harmonized System (GHS)
  • Describe the changes to WHMIS that are expected because of the adoption of GHS rules for classification, labelling, symbols/pictograms, and safety data sheets (SDSs)
  • Provide advice on steps that suppliers and employers can take in order to make a successful transition to WHMIS After GHS


This 42-page publication describes an overview of the anticipated changes to the WHMIS system after GHS principles are adopted. While exact details of the revised legislation will not be known when it is published in the Canada Gazette II, sufficient information is known to encourage workplaces to begin preparing for changes. This overview covers the basics of classification, safety data sheets, symbols and pictograms, labels, hazard statements, and precautionary statements.

Note: The information provided in WHMIS After GHS: Preparing for Change should not be regarded as “fixed” or “unchangable”. This publication will be updated as required as new information becomes available.
