加拿大已取消与美国联合举办的戈迪豪国际大桥开幕庆典 [1][2]。该大桥耗资数十亿美元、历时多年规划建设，跨越底特律河连接美国密歇根州和加拿大安大略省温莎 [2]。原定周五由两国高层出席的联合仪式被取消，改为各自举办独立活动 [2]。大桥预计周一开放车辆通行，8月5日开放行人和自行车通行 [2]。
此次取消背景为美国总统特朗普本周宣布对加拿大商品征收50%关税 [1][2]。特朗普指责加拿大对美国汽车、酽酒和乳制品存在不公平歧视 [1]。这一举措使美国与其最亲近的盟国之一的关系进一步恶化 [1]。
根据特朗普的计划，关税将于8月19日生效，涉及蜂蜜、酒类、水泥、乳制品等多种商品，但排除能源产品和关键矿物 [3]。加拿大专家预计约280亿加元（19.8亿美元）的出口将受影响，占加拿大对美年度出口约5% [3]。一项经济分析预测，该关税政策可能在2026-2027年使加拿大经济增长下降0.2-0.3% [3]。德斯贾丁银行首席副经济学家巴特利特表示，关税可能对就业和消费产生抑制作用 [3]。
加拿大总理卡尼周二表示与特朗普同意加强贸易谈判 [3]。谈判预计在关税生效前30天内进行 [2]。底特律是美加边境最大的卡车交通港口，超过70%的加拿大出口流向美国 [2]，使得该大桥的开通时机对两国经济更显敏感。
Canada has scrapped a planned joint ceremonial opening of the Gordie Howe International Bridge with the United States, originally scheduled for Friday, following U.S. President Trump's announcement of 50 percent tariffs on Canadian goods. [1][2] The two countries will instead hold separate inaugural events for the bridge, which spans the Detroit River and connects Michigan to Ontario. [2]
Trump has accused Canada of unfair trade practices involving automobiles, alcoholic beverages, and dairy products, citing these grievances as justification for the tariff action. [1] The tariffs are set to take effect on August 19 and will affect approximately CAD 28 billion (USD 19.8 billion) in Canadian exports annually—roughly 5 percent of Canada's total annual exports to the United States. [3] Products subject to the tariffs include honey, alcohol, cement, dairy, and wood products, though energy products and critical minerals are excluded. [3]
The Gordie Howe bridge represents the culmination of a multi-billion-dollar, years-long construction project that began in 2018. [2] Canada funded the bridge's construction, and a Canadian authority, the Windsor-Detroit Bridge Authority, will operate it. [2] Under terms of the arrangement, Canada will share a portion of toll revenues with the U.S. government over a 15-year period. [2] The bridge is expected to open to vehicular traffic on Monday, with pedestrian and bicycle access commencing on August 5. [2]
Detroit represents the largest truck crossing point on the U.S.-Canada border, with over 70 percent of Canadian exports flowing through the United States. [2] Canadian Prime Minister Carney stated on Tuesday that both countries have agreed to intensify trade negotiations. [3] Negotiations are expected to occur within 30 days before the tariffs take effect. [2] Analysts suggest the tariffs may serve as a negotiation tactic, though economic modeling indicates they could reduce Canadian economic growth by 0.2 to 0.3 percent in 2026–2027. [3]
