The largest energy trading partner to the United States is Canada, according to the US Census Bureau annual data report.
While energy accounted for about 5% of the value of all U.S. exports to Canada, it was also responsible for more than 19% of the value of all U.S. imports from Canada in 2016.
In terms of imports, crude oil makes up the largest percentage of business with 3.3 million barrels per day coming into the US via Canada.
The amount of oil coming in accounted for 41% of all US crude imports last year.
Yet, despite the increase in volume, the global downturn in oil price has resulted in falling sales figures from $83billion in 2014, to $47bilion in 2015 and $36billion in 2016.
Liquefied natural gas (LNG) exports from Canada are also making a growing impact on trade between the two countries, accounting for $5.9billion in trade last year.
