Canadian Prime Minister Mark Carney described the latest U.S. tariffs as relatively modest compared with previous measures while saying Ottawa was assessing their significant effects on individual companies and sectors. The White House said some Canadian dairy products, motorcycles and most alcoholic beverages would be barred from U.S. imports starting September 29, after President Trump threatened to block Canadian private-jet maker Bombardier from selling in the United States. The threat has drawn criticism from Kansas Sens. Jerry Moran (R) and Roger Marshall (R), who cited Bombardier’s importance as an employer in Kansas. Canada’s retaliatory tariffs on $27.6 billion of U.S. products took effect Tuesday, with 15%, 25% and 50% rates covering close to 6% of U.S. exports to Canada last year. Carney said the two-day cabinet retreat in Banff would examine the trade war’s effects and reiterated that Canada was ready to negotiate a deal respecting its sovereignty and benefiting both countries. The dispute follows an August 22 U.S. tariff action covering approximately C$28 billion of Canadian goods and has fueled strong domestic support for Ottawa’s response, including 80% backing in a CTV News poll.
