Keystone is a critical project that will help the United States meet its growing energy needs. By sending Canadian oil to U.S. refineries, this pipeline will reduce our dependence on foreign oil and create jobs across the country. That's why we've been working hard to make sure it's built safely, efficiently, and in accordance with all of our environmental laws and regulations.Keystone is a great way to get access to oil from Canada's vast oil sands, a controversial resource that can yield large amounts of hard-to-extract heavy oil.Transporting this liquid gold safely and efficiently is key for us all. That's why TC Energy has proposed the Keystone Pipeline system that will transport new finds from the ground up to U.S. refineries in record time -- 2,687 miles (4,324 km) long!
