Distributors June 1, 2018 September 1, 2018
Employers December 1 , 2018 No change


The change to compliance deadline also extends the period where either WHMIS 1988 or WHMIS 2015 Labels and Safety Data Sheets may be used.

This notice will be published in the Canada Gazette Part II, likely by May 31, 2017. For more information, please follow this link.

This extension is being granted in part to amend the Hazardous Products Regulations (WHMIS 2015) to restore the use of prescribed concentration ranges in Section 3 of an SDS without the need for a HMIRA Claim for Exemption (trade secret) Registration.

The proposed amendments to restore prescribed concentration ranges to the Hazardous Products Regulations (WHMIS 2015) to be expected to be published in summer 2017.

Trade secrets claims for a chemical identity or CAS# will still need a HMIRA Claim for Exemption Registration.
