What are we doing?

Based on the information obtained through the categorization process, this substance has been identified as a high priority for further action. As such, it has been included in the first batch of substances released under the Government of Canada's Challenge to industry and other stakeholders.

Under the Challenge, the Government of Canada will use existing legal tools and the regulatory process to obtain information from industry and other stakeholders on how they are managing this substance. New information will be reviewed by Government of Canada scientists to determine what further actions may be necessary to ensure that the health of Canadians and their environment are protected. If new information is not provided, the Government of Canada will nevertheless take action on a precautionary basis.
