The Workplace Hazardous Materials Bureau of Canada has announced delays in WHMIS 2015 compliance deadlines.


On February 11, 2015, the Government of Canada modified the Workplace Hazardous Materials Information System (WHMIS) 1988 to incorporate the Globally Harmonized System of Classification and Labelling for Chemicals (GHS) – now referred to as WHMIS 2015.


WHMIS 2015 has been introduced through a three-stage transition period that is synchronized nationally across federal, provincial and territorial jurisdictions.  However, Orders in Council have recently been approved to defer two of the transition deadline dates. The updated deadlines are:


  • Manufacturers and importers now have until June 1, 2018 to comply with the WHMIS 2015.  The deadline of June 1, 2017 has been delayed by one year to June 1, 2018.
  • The second deadline of June 1, 2018 has been delayed by three months to September 1, 2018.


The currently imposed deadline for employers by federal, provincial and territorial (FPT) agencies responsible for occupational safety and health (OSH) in the workplace remains unchanged at December 1, 2018.


During the transition period, which is anytime between now and these newly imposed deadlines, manufacturers and importers can use either WHMIS 1988 or WHMIS 2015, but must be fully compliant with either one or the other.


Transition phases for WHMIS 2015 are as follows:
