A notice or order has been published indicating that the significant new activity (SNAc) provisions of CEPA apply to this substance. This action can be taken when it is suspected that new activities involving a substance could result in the substance becoming toxic under CEPA.

The SNAc provisions of CEPA trigger an obligation for a person to provide the Government of Canada with information about a substance when proposing to use, import or manufacture the substance for a significant new activity. The government then assesses the substance for potential risks to the environment and/or human health. If risks are identified, the government may impose risk management measures.

To access all SNAc notices and orders published under the authority of CEPA, refer to Canada's Open Government Portal.

A notice or order has been published indicating that the significant new activity (SNAc) provisions of CEPA apply to this substance. This action can be taken when it is suspected that new activities involving a substance could result in the substance becoming toxic under CEPA.

The SNAc provisions of CEPA trigger an obligation for a person to provide the Government of Canada with information about a substance when proposing to use, import or manufacture the substance for a significant new activity. The government then assesses the substance for potential risks to the environment and/or human health. If risks are identified, the government may impose risk management measures.

To access all SNAc notices and orders published under the authority of CEPA, refer to Canada's Open Government Portal.
