GHS/WHMIS Update: What You Need to Know Now


Last month, the Government of Canada announced the modifications to the Workplace Hazardous Materials Information System (WHMIS) to incorporate the new GHS (Globally Harmonized System of Classification and Labeling of Chemicals) regulations.

The Hazardous Products Act (HPA) was amended and was replaced by new regulations, referred to as the Hazardous Products Regulations (HPR).

The modified WHMIS is now being called WHMIS 2015, and it features the new criteria for classifying hazards and the new requirements for labels and safety data sheets (SDSs).  The Controlled Products Regulations (CPR) and the Ingredient Disclosure List were both repealed.

Suppliers, employers and workers in Canada can use a transition period to adjust to the changes. During that time, they must comply with either WHMIS 1988 (repealed CPR/old HPA) or WHMIS 2015 (HPR/new HPA). The classification, label and SDS must comply with whichever law and regulation is selected.  A combination of the two WHMIS systems can’t be used.

A new website focusing on the transition to WHMIS (Workplace Hazardous Materials Information System) 2015 has launched, providing a resource for organizations working to transition from the old WHMIS to the new system, which takes on elements of the Globally Harmonized System of Classification and Labeling of Chemicals (GHS).

The website,, is targeted to anyone who needs this information, from employers and their workers to suppliers and trainers. was created by the Canadian Centre for Occupational Health and Safety (CCOHS) in collaboration with the Workplace Hazardous Materials Bureau of Health Canada.
