During a period of strained trade negotiations in late August, Donald Trump took to Truth Social to declare, “WE DON’T NEED CANADA, THEY NEED US!” However, this assertion overlooks a significant strategic reality: much like China, Canada possesses critical metal resources that are essential for modern defense capabilities.
Canada remains the United States’ largest foreign supplier of minerals, providing approximately $47 billion worth of materials annually. A prime example is aluminum, 60% of which is consumed by the US each year and sourced from Canada. This supply chain is bolstered by remote rivers that offer smelting facilities access to abundant, low-carbon electricity at low cost.
The military application of this metal is extensive, ranging from ship hulls and aircraft fuselages to shell casings. The F-35 fighter jet, a centerpiece of Pentagon modernization, features an airframe composed of roughly 40% aluminum. Acknowledging this dependency last month, Trump admitted, “This country desperately needs aluminum. We get it all from Canada for the most part, and we need it badly.” Despite his public stance, the administration has largely excluded metals from new tariff proposals, highlighting the practical reliance on Canadian resources even as political rhetoric suggests otherwise.
