As part of the implementation of the GHS in Canada, an Ad Hoc Expert Group on Chronic Hazards was established to examine the application of the GHS chronic and sub-chronic hazard classes to consumer chemical products. Currently, regulations for consumer chemical products do not cover these hazards. This Expert Group will provide recommendations back to the Consumer Chemical Sector Working Group.

*For Mixtures: The WHMIS Working Group recommended a cut-off value of 0.1% with reduced labelling requirements for mixtures containing sensitizers at concentrations between 0.1% and 1.0%. Where an elicitation response is evident below 0.1%, the mixture should be classified and supplementary labelling used accordingly. Supplementary labelling here only includes a statement identifying the sensitizer present in the mixture.
