Justin Trudeau, Canadian Prime Minister:

Canada will be responding to the U.S. trade action with 25 percent tariffs against $155 billion worth of American goods, such as American beer, wine, and bourbon, fruits and fruit juices, including orange juice, along with vegetables, perfume, clothing, and shoes.
