The intensified trade tensions between Canada and the United States have hit the air passenger business between the two countries hard. According to the latest report released by aviation analysis company OAG, air travel between Canada and the United States has "collapsed", and flight bookings in the next six months have dropped by more than 70% compared with the same period last year, especially the sharp drop in demand from Canada. Analysts believe that the main reason why Canadian tourists have postponed or canceled their travel arrangements to the United States may be the continued uncertainty caused by the tariff dispute. In addition, US President Trump's remarks on "making Canada the 51st state of the United States" have also aroused the anger of Canadians.
