Donald Trump stated that Canada has been "ripping off" the U.S. for decades, alleging that they charge American farmers 400% or more in tariffs and have driven many U.S. companies out of business. He cited an instance where Canada allegedly refused to certify Gulfstream Jets for 10 years to protect a Canadian competitor, until he intervened. Trump described Canada as the "most difficult and unreasonable" country he deals with, asserting they feel entitled but will no longer be.
