WHMIS 2015: We're Almost There!

The multi-year WHMIS 2015 transition is getting closer to the deadline.  Now it's not too late to make sure that employers and workers are up to speed with courses and information to help them understand the system.

Remaining Transition Phases

Phase 2

From June 1, 2018 to August 31, 2018

Distributors can continue to sell, and those importing for their own use can continue to use, hazardous products with labels and (M)SDSs that are compliant with WHMIS 1988 or WHMIS 2015.

During this phase, manufacturers and importers are required to only sell or import hazardous products with labels and SDSs that are compliant with WHMIS 2015. The transition to WHMIS 2015 for manufacturers and importers is now complete.

Phase 3

From September 1, 2018 to November 30, 2018

During this phase, manufacturers, importers and distributors are required to sell or import only those hazardous products that are complaint with WHMIS 2015. At this point, transition to WHMIS 2015 is complete for all suppliers.

Full Implementation of WHMIS 2015

By December 1, 2018, all suppliers and employers will be required to be in compliance with the new Hazardous Products Act (HPA) and Hazardous Products Regulations (HPR).
