On November 28, 2012, the Canada-U.S. Regulatory Cooperation Council (RCC) held a webinar to discuss its RCC Nanotechnology Work Plan. Canada and the U.S. created the RCC to align better their regulatory approaches in a number of areas, including nanotechnology. According to information presented during the webinar, while the U.S. has received 137 notifications concerning nanomaterial substances, Canada has received only 16. While most of the nanomaterial substances notified in the U.S. were inorganic carbon, most of those notified in Canada were mixed metal oxides. During the webinar, both Canadian and U.S. spokespersons noted the difficulty in sharing information, due to confidential business information (CBI) claims. The RCC would like to be able to share information to inform better their regulatory programs and risk assessment/management approaches. This would include:
- General Substance Information: Substance name, company, applications, volumes; and
- Technical Substance Specific Information: Physchem properties, technical studies, and use pattern information.
The RCC requested that industry provide more information on the commercial distribution of nanomaterials, as well as more transparency by claiming confidentiality of only that information absolutely critical to market advantage.
To compare risk assessment and risk management practices to highlight and identify best practices, data gaps, and differences between the two jurisdictions, the RCC sought nominations of a nanomaterial substance for a case study. Four nanomaterial substances were nominated: multiwall carbon nanotubes, nanocrystalline cellulose, nano silver, and titanium dioxide. The RCC has selected multiwall carbon nanotubes for the case study. The RCC intends to hold in March 2013 a workshop in Washington, D.C., to discuss information collected to date and approaches moving forward. In spring 2013, the RCC will hold one or two conference calls or webinars to discuss information gathered between countries and the path forward. Finally, in fall 2013, the RCC expects to hold a stakeholder consultation/workshop on results to date.
