The US midwestern states depend entirely on imports from Canada of as much as 3.5 million barrels a day. In 2018 the Canadian government bought an unfinished pipeline from Alberta to British Columbia, the Transmountain pipeline for $18 billion. This is now finishing completion in 2024. For years the pipelines bringing oil from the north to midwest states reduced the cost differential between Canadian crude and US crude to $18 for a price of $47 a barrel. The Transmountain pipeline will take some of that oil and move it to British Columbia ports where it can loaded onto tankers heading to Asia. This will increase the cost of Canadian crude into the midwest and be reflected in prices at the pump.
