The Workplace Hazardous Materials Information System (WHMIS) is Canada’s national hazard communication standard. The key elements of the system are hazard classification, cautionary labelling of containers, the provision of (material) safety data sheets ((M)SDSs) and worker education and training programs.
On February 11, 2015, the Government of Canada published the Hazardous Products Regulations (HPR), which, in addition to the amendments made to the Hazardous Products Act (HPA), modified the Workplace Hazardous Materials Information System (WHMIS) 1988 to incorporate the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) for workplace chemicals. This modified WHMIS is referred to as WHMIS 2015.
