Amendments to the OHS Act and the WHMIS Regulation that adopt the GHS and reflect WHMIS 2015 took effect July 1, 2016. To give workplace parties time to adjust to the new requirements, there will be a transition period:
- May 31, 2018: Employers have until this date to continue to receive and use hazardous products with either the old WHMIS labels and SDSs or the new ones
- June 1, 2018-Nov. 30, 2018: Employers must bring any hazardous products still in the workplace with the old WHMIS labels and SDSs into compliance with the new requirements.
- Dec. 1, 2018: The transition to the new WHMIS labels and SDSs must be complete.
