The Financial Post reports in its Tuesday edition that Prime Minister Justin Trudeau warned executives that President Donald Trump was serious about annexing Canada due to its wealth in critical minerals. A Bloomberg dispatch to the Post reports that Canada produces over 60 minerals, including nickel, potash, aluminum and uranium, with significant deposits found across the country. For instance, Ontario is rich in nickel and copper, Quebec has lithium and rare earth metals, while British Columbia offers molybdenum and niobium. In 2023, the U.S. was Canada's largest buyer of critical minerals. President Trump has suggested that Canada could avoid tariffs by becoming the 51st state. He reduced his initial tariff threat on raw materials from 25 per cent to 10 per cent. About a quarter of U.S. uranium needs are fulfilled by gigantic mines in Saskatchewan, owned by companies like Cameco. More than 80 per cent of U.S. potash comes from Canada, including from Nutrien. As well, about 70 per cent of U.S. aluminum is supplied by plants in Quebec and British Columbia. Nickel from Northern Ontario is shipped to the U.S. for weapons manufacturing, along with zinc and germanium from Teck Resources' smelter in British Columbia.
