Environment Canada and Health Canada opened a consultation on a Proposed Approach to address Nanoscale Forms of Substances in the Domestic Substances List. Established under the Canadian Environmental Protection Act (CEPA 1999), the DSL lists substances that are manufactured in or imported into Canada, substances that are not listed are considered new.
In a document entitled Proposed Approach to address Nanoscale Forms of Substances in the Domestic Substances List, Canadian agencies suggested to establish a list of existing nanomaterials in Canada with the use of ‘a mandatory survey under section 71 of the Act […] to obtain the essential data needs to support the development of the list of the existing nanomaterials in Canada and subsequent prioritisation activities for those substances’.
The prioritisation of existing nanomaterials for action shall then take into account several factors (e.g. Commercial status in Canada, Potential for human or environmental exposure, Potential for toxicity or harmful effects, etc.) with the aim of defining if a nanoscale substance require further examination or risk assessment / risk management.
Environment Canada and Health Canada have planned an information gathering survey for June 2015.
