Canada will impose retaliatory tariffs on US steel, electronics, and other products starting September 8, 2026, in response to President Donald Trump's 50% tariffs on Canadian goods, according to Prime Minister Mark Carney. The move marks a significant escalation in the trade dispute between the two nations. Carney described the situation as a trade war, emphasizing that Canada will match the US tariffs dollar for dollar to protect its workers, farmers, and businesses.

The decision comes after failed trade talks that led to the imposition of the new US tariffs. Trump criticized Canada for seeking the benefits of being a US state without full membership, highlighting tensions in the bilateral relationship. Canadian officials argue that the tariffs unfairly target Canadian industries and threaten economic stability.

The retaliatory measures are expected to affect a range of US imports, including steel and electronics, which are key sectors for both countries. While the exact scope of the Canadian tariffs remains under review, the timeline suggests a direct response to the US policy. The trade conflict continues to raise concerns about the impact on global markets and bilateral relations.
