At 00:00 Eastern Canada Time on the 8th, which is 12:00 Beijing time on the 8th, the Canadian government's measures to impose countervailing tariffs on US goods officially came into effect. The Canadian side said that the total amount of US goods affected by the anti-tariffs this time is comparable to the value of the goods involved in the 50% tariff imposed by the US side on Canada, achieving “equal and equal” countermeasures. The Canadian federal government announced on August 25 that it will impose countervailing tariffs on US goods worth 27.6 billion Canadian dollars, or about 20 billion US dollars. According to the list published by the Canadian Treasury, the current countertariff is mainly concentrated in the fields of steel and aluminum, dairy products, home appliances, agricultural equipment, pulp and paper, plastics, and electronic products. The tax rates are divided into three levels of 15%, 25%, and 50%. Among them, import tariffs on most US steel and aluminum products will be raised from 25% to 50%; dairy products such as cheese, fish, seafood, and some steel-aluminum derivatives will be subject to 25% tariffs. US President Trump signed several announcements on July 20, imposing 50% tariffs on hundreds of specific goods worth about 20 billion US dollars, such as red wine, hockey sticks, and cement, imported from Canada in accordance with section 338 of the “Smoot-Hawley Tariff Act”. On August 21, Canadian Prime Minister Carney issued a statement announcing the suspension of trade negotiations with the US and the recall of the Canadian negotiation delegation. On August 22, the additional tariff measures imposed by the United States officially came into effect. On the same day, the Canadian government announced that it will implement equal retaliatory tariff measures against the US starting September 8.
