It is going to get worse. Iron/steel and aluminum are some of the most common elements on the planet. They are literally everywhere. The cost is in the energy for production, and to a lesser extent transport. But energy is not only going to become more expensive but actually hard to get (thank you again AI). Canada has energy, from empty land for wind/solar/hydro, to oil, to enormous piles of uranium ore. That is not an enemy worth making.
