Nanomaterial

In March 2010, Health Canada launched a web-based consultation on the Interim Policy Statement on Health Canada's Working Definition for Nanomaterials. The consultation was open for comment from March 1 to August 31, 2010. During that period, Health Canada received a total of 29 submissions from companies, industry groups, governments, academia, public interest groups and interested citizens.

Health Canada made changes to the Interim Policy Statement based on stakeholders' feedback. Changes were also informed by developments in international norms, evolving scientific evidence and regulatory program needs. These changes appear in the Policy Statement on Health Canada's Working Definition for Nanomaterial which will continue to be updated as the body of scientific evidence and international norms progress.

Health Canada's responses to key stakeholder comments are summarised in the following documents:

• Summary of Comments Received on the Interim Policy Statement on Health Canada's Working Definition for Nanomaterials - March to August 2010.
• Frequently Asked Questions Related to the Policy Statement on Health Canada's Working Definition for Nanomaterial.
