RE:30% upwards if Trump Tweets..no oil tax for CanadaActually the cross border tax is designed for companies who move factories overseas and sell the manufactured products back to the US, not designed for commodities.
Secondly US gasoline prices will soar approx 30% if Trump implement tax for importing oil. Trump will immediately face a big protest all over USA.
After all, if Trump tax import oil, OPEC oils , Mexican oils etc will also be taxed, not only Canadian oils. Resultant rise in WTI prices will probably offset a big portion of of the import tax.
