1. Introduction

1.1 Objective of this consultation

Environment Canada and Health Canada are proposing a new approach to address certain nanomaterials under the Canadian Environmental Protection Act, 1999 (CEPA). Environment Canada and Health Canada have prepared this consultation document to inform stakeholders and solicit feedback on key elements of the proposed approach to address nanoscale forms of substances on the Domestic Substances List. This consultation document is intended to serve as a starting point for dialogue with stakeholders.

1.2 Consultation process

This consultation document will be posted on the CEPA Environmental Registry^{Footnote 1} and has been distributed by email to Canadian stakeholders involved in the Chemicals Management Plan and/or nanomaterials, including representatives from other federal departments and agencies, provincial and territorial governments, industry, academia, and non-governmental organizations. International stakeholders are also being consulted.

Environment Canada and Health Canada welcome broad participation in this consultation, for example through the distribution of this consultation document to other potential stakeholders. There will be multiple opportunities for stakeholders to participate and provide input as this approach is developed and implemented (for example, consultation documents, workshops, meetings).

Stakeholders may provide their written comments on this consultation document by mail, fax or email via the contact information provided in Section 7. Environment Canada and Health Canada will review all written comments received during the consultation period. Feedback will be considered in the finalization of the approach.
