Saudia Arabia is US second oil importer to Canada.
And this year the import from Saudi Arabia is growing (more than 30% since January), while from Canada the import is shrinking (~ 20%).
Over the past years, the US imported roughly double the amount of oil from Canada in relation to Saudi Arabia.
80 000 to 90 000 barrels (CAN) to ~ 45 000 barrels (SA) per month.
EDIT: Crude Oil only is about 65 000 to 45 000 barrels, over the past years.
