Mr. Chair, I'll be very brief on this.
Nanotechnology is, as the member knows, an emerging technology. All countries are looking at how it can be regulated. We are cooperating with OECD countries to understand how we could move forward, and that requires some basic understanding of how small particles behave. In order to regulate, we'd have to be very specific about issues such as the kinds of notifications, assessments, and studies we want. That work is being done in collaboration with the OECD right now.
