加拿大对美国商品征收报复性关税，贸易战升级

加拿大于周二对美国商品正式实施报复性关税，涉及近280亿加元的美国产品，税率高达50%1。这一举措标志着两国贸易紧张局势的进一步升级，自8月底谈判崩溃以来，双方未能恢复协商1。加拿大随后从关税清单中移除了新鲜鱼类和龙虾1。

美国此前已对加拿大汽车和卡车征收25%的关税，对钢铁、铝和木材也征税1。8月底，美国总统特朗普对加拿大乳制品、酒精、曲棍球棍和香水等商品征收50%的新关税1。美国贸易代表格瑞尔威胁可能禁止进口一些加拿大产品1。特朗普还威胁若庞巴迪公司不将制造业迁往南方，将停止与其所有业务1。

加拿大总理卡尼表示对加关税为"逐元匹配"1。民调显示加拿大大多数人支持对美国征收报复性关税1。加美双边贸易价值近900亿美元（2025年）1。8月加拿大失业41,000人1。加拿大GDP在第二季度增长3.3%1。庞巴迪对加拿大年度GDP贡献超70亿加元（2024年）1。

Canada has imposed retaliatory tariffs on American goods worth approximately CAD $28 billion (USD $20 billion; GBP £15 billion), with rates reaching as high as 50%, effective this week.1 The measures come after negotiations between the two countries collapsed at the end of August with no signs of resumption.1 Canada subsequently removed fresh fish and lobster from its tariff list.1

The bilateral trade relationship between Canada and the United States is valued at nearly USD $900 billion annually.1 The United States currently maintains a 25% tariff on Canadian automobiles and trucks, alongside existing levies on Canadian steel, aluminum, and timber.1 In late August, the Trump administration introduced additional 50% tariffs on Canadian dairy products, alcohol, hockey sticks, and perfume.1

Canadian Prime Minister Justin Trudeau stated the country is prepared for negotiations with the United States, characterizing the Canadian tariffs as a "dollar-for-dollar" match to US duties.1 However, U.S. Trade Representative Jamieson Greer countered that the onus remains on Canada to move forward.1 Greer has also threatened potential bans on certain Canadian imports.1 Additionally, President Trump warned that if aircraft manufacturer Bombardier does not relocate its manufacturing operations southward, the U.S. will cease all business dealings with the company.1 Bombardier contributes more than CAD $7 billion annually to Canada's GDP.1

A poll indicates that most Canadians support retaliatory tariffs against the United States.1
