The U.S. military depends significantly on Canadian minerals, including aluminum and nickel, despite recent trade tensions and statements by Donald Trump suggesting the U.S. does not need Canada.
Canada is the largest foreign supplier of minerals to the U.S., providing about $47 billion worth annually. Sixty percent of the aluminum used by the U.S. comes from Canada, which is essential for military applications such as aircraft and ship construction. The U.S. military relies heavily on aluminum for components like shell casings, ship hulls, and aircraft fuselages, including the F-35 fighter jet, which is about 40% aluminum.
Despite Trump's claims that the U.S. does not need Canada, metals have been largely exempted from new tariffs. However, Canadian officials have warned that supply disruptions could occur if tensions escalate further, potentially affecting U.S. access to critical materials like nickel and germanium. Canada supplies about half of the U.S. nickel, which is vital for steel alloys in jet engines and armor plating. British Columbia has also suggested restricting germanium exports to the U.S., a material used in military equipment and solar panels. These materials are difficult to source elsewhere, with China restricting exports of gallium and other critical metals, making Canada's role even more significant.
Why it matters
