The tariffs target sectors such as motor vehicles, alcohol, and dairy. The new tariffs will be implemented under Section 338 of the Tariff Act of 1930, a rarely used provision. ## Affected products The new tariffs cover a range of Canadian products, from wine to hockey sticks to cement. US officials stated that these tariffs will apply regardless of whether the products are covered under the existing US-Canada free trade agreement. Ontario Premier Doug Ford suggested that Canada should retaliate with similar measures. ## Background of trade tensions Trade tensions between the US and Canada have escalated in recent years due to Trump's heavy tariffs and Canada's retaliatory measures. The Trump administration further strained relations by announcing it would not renew the USMCA trade agreement. Despite being long-time allies and trade partners, the relationship between the two countries is deteriorating. ## Wildfires and tariffs Last week, Trump claimed that wildfires in Canada caused air pollution in the US, resulting in billions of dollars in damages, and suggested these costs should be added to Canada's tariffs. However, officials clarified that the newly announced 50% tariffs are unrelated to the wildfires but noted that Trump has requested options on that matter. ## Rarely used legal authority Section 338 grants the president the authority to impose tariffs of up to 50% on goods from countries found discriminating against the US. This provision has reportedly gone unused for decades. According to a 2016 article by law firm Covington and Burling LLP, there is no public record of Section 338 being used since 1949. ## Implications of a trade war The new US tariffs on Canada risk further straining trade relations between the two countries. If Canada retaliates, the trade war could escalate, potentially causing significant economic consequences, particularly in sectors like motor vehicles and agriculture. The tension between the two nations could also impact global trade balances. ## Sources covering this story - https://www.cnbc.com/2026/07/20/trump-tariffs-canada-trade.html — --- _Summary written by Brifing from the original reporting.
