Key facts. In 2021, Canada was the seventhlargest producer of iron ore in the world. Canada's iron ore is mined in Quebec, Newfoundland and Labrador, and Nunavut. The top three iron oreproducing countries (Australia, Brazil and China) accounted for 63% of global production. The primary use of iron ore is to make steel, which is recyclable.
