Implementation of WHMIS 2015 Across Canada

On Feb. 11, 2015, the federal government published the final Hazardous Products Regulations (HPR), which implement the UN’s Globally Harmonized System (GHS) for classifying and labelling chemicals. The new WHMIS, called WHMIS 2015, is based on the requirements contained in the HPR and the Hazardous Products Act, as amended in 2014. These new regulations directly impact manufacturers, importers and distributors of hazardous products as well as federally-regulated employers. But in terms of workplace safety, most employers in Canada are regulated by their provincial or territorial OHS laws. So until those jurisdictions amend their OHS statutes and/or regulations to reflect WHMIS 2015, those employers are still bound by the requirements under WHMIS 1988 (as the old WHMIS is now being called). This chart tracks the progress in each jurisdiction on making such changes and will be regularly updated.
