Environment Canada has issued an Advisory Note concerning notification obligations for manufacturers and importers of nanomaterials.
The Advisory Note confirms that nanomaterials are subject to the same regulatory requirements as chemicals and polymers, and accordingly, manufacturers and importers of nanomaterials are required to submit a New Substances Notification package prior to the manufacture in or import into Canada of new nanomaterials.
Nanomaterials which are manufactured in or imported into Canada that are not listed on the Domestic Substances List are considered new. The nanoscale form of a substance is considered a "new" substance if it has a unique structure or molecular arrangement. Accordingly, new nanomaterials are subject to notification under the regulations.
