You raise an important point. In a broader context, if I can talk about other critical materials, let me talk about critical minerals as an example. That will be very important in the transition towards electric vehicles, and they are also used in a lot of electronic products. I know both Canada and the Biden administration are looking at those considerations very carefully because, as you pointed out, they're critical elements in the supply chain.
One of the things we're doing as we move forward is ensuring that in both countries, for industries we strongly support, we look at all the different methods available to us to ensure we have that availability with respect to certain critical components.
I know the United States is looking at integrated circuits, but I know Canada also has the potential to be extremely helpful in the area of critical minerals because we're rich in that area. We're looking at North American self-sufficiency with respect to certain critical components.
