Canada will impose retaliatory tariffs on US products next month, following new US duties on Canadian goods, according to 読売新聞. Prime Minister Justin Trudeau said the move marks the end of the economic integration process between the two countries.
The Canadian government announced the countermeasures on Saturday, August 22, 2026, after the Trump administration imposed additional tariffs, including a 50% duty on certain Canadian products, as reported by The Wall Street Journal via ダイヤモンド・オンライン. The retaliatory package is valued at approximately 3.2 trillion yen, according to 日本経済新聞.
The tariffs will target US steel, dairy products, and other goods, per 共同通信. Canada has also suspended trade negotiations with the US, CNN.co.jp reports, with Ottawa matching the value of the US tariffs dollar-for-dollar.
Trudeau stated that the US had imposed "unreasonable conditions" on Canada, according to 日本経済新聞. The prime minister’s remarks suggest a significant breakdown in bilateral trade relations, which have historically been closely integrated through agreements like the USMCA.
The announcement follows a period of escalating friction between the two neighbors, with Washington's latest 50% tariff on select Canadian products serving as the immediate trigger for Ottawa's response. The Canadian countermeasures are scheduled to take effect next month, though the exact date has not been specified in the reports.
The suspension of trade talks adds another layer of uncertainty, as both countries had previously sought to resolve disputes through negotiation. The move signals that Canada is prepared to take a harder line against US trade policy.
What to watch next: Whether the US responds with further tariffs or returns to the negotiating table, and how the dispute affects cross-border supply chains in steel, dairy, and other sectors.
