Canada Postpones GHS Deadlines

June 7, 2017                                               Contact: Bill Balek

The Government of Canada announced that it is extending certain of the deadlines associated with Canada’s implementation of the Globally Harmonized System of Classification and Labeling (GHS). 

Background.  On February 11, 2015, Canada published the Hazardous Products Regulations (HPR) that revise the Workplace Hazardous Materials Information System (WHMIS) to incorporate the GHS.  The revised WHMIS is now referred to as WHMIS 2015.  As originally published, WHMIS 2015 is to be implemented in stages over three major dates.  Canada has now revised two (2) of those effective dates as indicated below.
