Just for clarity, so that everybody understands, critical minerals are a broad set of materials, of which Canada generates a large volume. They could be base metals. They also could be rare earths.
I think the question Sean is getting at here has particularly to do with rare earths: What do we need to be able to reshore and create a market for the development of these materials from Canada, through a North American or predominantly western-based supply chain?
The first thing is that there are some technological challenges, so research and development investment would be very helpful, particularly on sorting and manufacturing, but there are also downstream issues. For example, there is actually no current market within North America, more broadly speaking, or within Canada specifically for the manufacturing or consumption of these materials.
Thus, when the federal government is thinking about what measures it could put in place, I would hearken back to the presentation I made to this committee as part of the pre-budget consultation process and the conversation that Mr. Easter and I had after that session.
I would be happy to circulate again to this group a more detailed set of recommendations that MAC has developed, but at the end of the day, we're seeking R and D investments to support Natural Resources Canada, particularly Canmet, in bolstering the technological capacity for sorting and separating these materials. We're also seeking outside-the-box thinking about what the government can do to bring the types of advanced manufacturing back to Canada, back to North America, that rely on a stable supply of these materials that we have but are looking for markets to sell to.
