In 2015, Canada’s Workplace Hazardous Materials Information System (WHMIS) was updated to be in line with similar systems in the United States and other countries. It’s now referred to as WHMIS 2015 and also as the globally harmonized system (GHS). It’s being rolled out gradually until 2018, to give workers, employers, and suppliers enough time to adjust to the changes that affect classification of hazards, labelling requirements, and safety data sheets.
You can get much more information about this from these videos made by WorkSafeBC. One is for employers, one is for workers, and they’re both available with subtitles in Chinese, Korean, Punjabi, Spanish, and Vietnamese. The French one has audio in addition to subtitles.
