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.
The Controlled Products Regulations (CPR) and the Ingredient Disclosure List have been repealed. However, to provide Canadian suppliers, employers and workers time to adjust to WHMIS 2015, there is a transition period. During this period, suppliers are allowed to continue to comply with the repealed CPR, or they must comply with the new HPR. The supplier must fully comply with either the repealed CPR or the HPR for a specific controlled or hazardous product. The classification, label and (material) safety data sheet must comply fully with the specific regulation chosen by the supplier, and not a combination of the two.
During transition a product that is found to be non-compliant with the CPR must be voluntarily brought into compliance with the CPR, or the supplier will be forced to comply with the HPR, no matter which transitional phase applies at the time.
