美国总统特朗普宣布将对加拿大商品征收50%的关税，新关税将在30天后生效。[1][2][3]这一决定是对加拿大报复性贸易措施的回应，特朗普指责加拿大在汽车、乳制品和酒精饮料方面对美国商品实施歧视性税收。[2]
新关税的覆盖范围包括葡萄酒、冰球杆和水泥等商品。[1]这些产品此前受到《美墨加协议》的保护。[1]能源产品、鱼类、关键矿物、钾肥、钢铁和铝被豁免在外。[1][3]根据测算，此举将影响约280亿加元（198亿美元）的加拿大对美出口，相当于加拿大经济的0.8%。[3]
加拿大总理马克·卡尼表示，他已与特朗普通话，双方同意在未来几周内深化并加快谈判。[3]卡尼誓言将"加强"贸易谈判以解决悬而未决的问题。[2]他还声称特朗普的举措威胁到加拿大主权。[2]
安大略省长道格·福特呼吁加拿大进行对等反制，表示"如果这些关税生效，加拿大应该以关税对关税、以金额对金额进行回应"。[1]加拿大已对美国钢铁、铝和车辆征收25%的反制关税。[2]
此外，加拿大基础设施部宣布取消与美国的联合仪式来庆祝戈迪豪国际桥通车。[4]该桥连接底特律和温莎，计划于7月27日开放通行，项目耗资近44亿美元。[4]加拿大基础设施部发言人杰娜·加萨贝赫表示，"鉴于本周美国威胁的贸易行动，两国之间进行庆祝活动是不恰当的"。[4]加拿大现计划于7月24日单独举办仪式。[4]
加拿大乳制品供应管理制度也成为贸易冲突的焦点。[5]特朗普将200亿美元的关税针对这一制度，该制度自20世纪70年代初以来一直存在。[5]美国乳制品生产商目前仅能进入加拿大3.5%的市场无关税进口配额，超配额进口乳制品的关税为200%-300%。[5]加拿大贸易部长多米尼克·勒布朗表示该制度是"加拿大经济和农村社区的基石"，77%的加拿大人支持保留这一制度。[5]
President Donald Trump has announced a 50% tariff on most Canadian goods, set to take effect in 30 days. [1][2][3] The move targets approximately $20 billion in Canadian exports to the United States, equivalent to 0.8% of Canada's economy. [3]
The tariffs will cover products including wine, hockey sticks, and cement. [1] However, energy products, fish, critical minerals, potash, steel, and aluminum are exempt from the new duties. [1][2][3] Trump cited Canada's alleged discriminatory treatment of American automobiles, dairy products, and alcoholic beverages as justification for the action. [2]
Canada's dairy supply management system has become a particular point of contention. [5] Under this system, established in the early 1970s, American dairy producers currently have access to only 3.5% of the Canadian market, while tariffs on over-quota imports reach 200%-300%. [5] The U.S. exported $1.3 billion in dairy products to Canada in 2025. [5] Trade Minister Dominic LeBlanc characterized the supply management system as "the cornerstone of Canada's economy and rural communities." [5] A poll found that 77% of Canadians support maintaining the system. [5]
Canadian Prime Minister Mark Carney responded by stating that he had spoken with Trump and the two agreed to "deepen and accelerate" negotiations on the trilateral trade agreement in the coming weeks. [3] Carney said "Canada stands ready to engage intensively to address outstanding issues with the U.S." [1] Ontario Premier Doug Ford took a harder line, declaring that "if these tariffs proceed, Canada should respond tariff for tariff, dollar for dollar." [1] Canada has already imposed 25% retaliatory tariffs on American steel, aluminum, and vehicles. [2]
The trade escalation has prompted diplomatic fallout. Canada's Infrastructure Ministry announced the cancellation of a joint ceremony with the United States to mark the opening of the Gordie Howe International Bridge, which connects Detroit and Windsor. [4] A ministry spokesperson stated: "Given the trade actions threatened by the United States this week, it is inappropriate for the two countries to hold a celebratory event together." [4] The bridge, a $4.4 billion project that began in 2018, is scheduled to open on July 27. [4] Trump had previously demanded in February that Canada transfer at least 50% ownership of the bridge to the U.S. government. [4] Canada now plans to hold a separate ceremony on July 24. [4]
The tariffs are being imposed under Section 338 of the 1930 Trade Act. [1]
