On July 21, local time, Canadian Prime Minister Mark Carney said that after the US tariffs were announced, he had already spoken Mandarin with US President Donald Trump. Carney also said that if it takes effect, Canada will consider all coping options. The White House issued an announcement on the 20th saying that the US will impose an additional 50% ad valorem tariff on some Canadian products to deal with “the discriminatory measures taken by Canada against the US in the automobile and auto parts trade.” A factual list released by the White House on the same day shows that the US will impose tariffs on Canadian goods such as wine, ice hockey sticks, and cement, even if these products comply with the “US-Mexico-Canada Agreement.” The White House said that these tariffs are aimed at offsetting the burden and disadvantages caused by Canada's discriminatory practices, and that the new tariff measures will take effect on August 19, EST.
