Background
The Chemicals Management Plan (CMP) is a Government of Canada initiative through which the risks of exposure of people in Canada and the environment to substances are assessed and managed. As part of the CMP, the Minister of the Environment (the Minister) may apply the significant new activity provisions (the SNAc provisions) of the Canadian Environmental Protection Act, 1999 (the Act) to certain substances to request information to assess the potential for environmental and human health risks when the substance is used in a significant new activity.
A significant new activity is an activity that results in or may result in the entry or release of a substance into the environment in a greater quantity or concentration than before, or in different circumstances than those in which the substance previously entered or was released into the environment. If risks are identified, the Government of Canada may recommend risk management measures to mitigate them.
