According to a May 6, 2023, Canada Gazette notice, the Minister of the Environment, pursuant to the Canadian Environmental Protection Act, 1999 (CEPA), intends to unmask the identities of 132 substances currently on Part 3 of the Domestic Substances List (DSL) in accordance with the Approach to disclose confidential information and promote transparency in chemicals. The annexed proposed Order includes the masked names and confidential accession numbers of the substances proposed for unmasking. The notice states that any person who objects to the unmasking of a substance subject to the notice should submit a masked name application for each substance to the Substances Management Information Line, including a masked name that complies with the Masked Name Regulations and the justification outlined in Section 7.2.2 of the Guidance Document for the New Substances Notification Regulations (Chemicals and Polymers).
The notice states that any person who conducts commercial activities with a substance that they believe to be subject to the notice of intent may provide the Chemical Abstracts Service Registry Number® (CAS RN®) to the New Substances program for confirmation. Any person who objects to the unmasking of a substance subject to this notice should submit a masked name application for each substance. Canada will take comments into consideration during the development of the final Order. Comments on the proposed Order are due July 5, 2023.
