US President Donald Trump has said he will follow through with his threat to hit imports from Canada and Mexico with 25% border taxes, known as tariffs, on 1 February. But he added that a decision about whether this would include oil from those countries has not yet been made.

President Donald Trump says his 25% tariffs on Canada and Mexico are coming on Saturday. Trump also said he'll "probably” decide on Thursday night whether to include oil from those countries as part of his import taxes.

If President Donald Trump's threat to tariff Canadian imports by 25% goes forward, 200 years of peaceful and profitable Great Lakes maritime trade will be at risk.
