New substances: Ministerial conditions


When the Minister of the Environment and Climate Change and the Minister of Health suspect that a new substance may meet the criteria for toxic under the Canadian Environmental Protection Act, 1999, control measures are imposed to minimize any risk to the environment or human health.

When Ministerial conditions are imposed, the notifier can manufacture or import the substance, subject to restrictions. The types of restrictions that may be imposed include:

The notifier and, if specified in the condition, the notifier’s customers are obliged to abide by these conditions and keep records as indicated. 

Substances subject to ministerial conditions are not eligible for addition to the Domestic Substances List. Therefore, any new notifier who wishes to manufacture or import the same substance must submit a New Substances Notification. This may result in similar conditions being imposed.
