Amateur analysis:
It’s worth noting that according to the NASDAQ, Canada is the largest close producer of Aluminum to the United States that (was) friendly geopolitically. America isn’t even on the top ten list of producers, though I suppose that could change. As far as bauxite reserves go, according to Statista neither Canada or the United States are particularly strong producers. Refining Aluminum is highly energy intensive (And that makes the price of energy highly related to the price of aluminum), and Canada's competitive advantage in Aluminum production is the fact that they have lots of hydro power to throw at it to do it in an (comparatively) environmental friendly manner. America can make the energy, but I think it’s unlikely to be as green - and if the energy costs are higher the bottom line won’t be as green either.
