Explanation of Transition Phases

WHMIS 2015 transition timelines for compliance have recently been updated in the information below to reflect the extensions that were granted on May 19 2017.

The following explanation refers to the transition provisions for WHMIS 2015 which stem from the Hazardous Products Act (HPA) and its associated regulations, the Controlled Products Regulations (CPR) and Hazardous Products Regulations (HPR).

For more information related to transition to employer requirements of WHMIS 2015 in specific jurisdictions, please direct enquiries to the federal, provincial, territorial (FPT) occupational health and safety (OSH) regulatory agencies, found in WHMIS Contacts.

Transition Phase 1 (coming-into-force to May 31, 2018)

The transition begins with the publication in Canada Gazette, Part II, of the final HPR, which set out the requirements of the WHMIS 2015 for suppliers.

During this time, either the old requirements under the CPR and old HPA (WHMIS 1988) or the new requirements under the HPR and new HPA (WHMIS 2015) can be followed to achieve compliance. Suppliers must use a label and (M)SDS for each hazardous product that either fully comply with the requirements of WHMIS 1988 or WHMIS 2015, but not a combination of the two.

Transition Phase 2 (June 1, 2018 to August 31, 2018)

This phase is the initiation of the phasing out of compliance with the old HPA and CPR, starting with manufacturers and importers. 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.

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

Transition Phase 3 (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 (December 1, 2018)

By December 1, 2018, all suppliers and employers would be required to be in compliance with the new HPA and HPR.
