Stock futures slip as U.S. and Canada appear headed for trade war

Stock-index futures slipped Sunday as investors digested signs that the United States and Canada are moving closer to a full-scale trade war. Canada is one of America’s largest trading partners, so the potential for sweeping tariffs and retaliatory measures carries meaningful consequences for both economies.

Futures provide an early read on how markets may open after the weekend. The two countries share deeply integrated supply chains, especially in autos, agriculture, and energy. A broad trade dispute could raise costs for businesses, disrupt cross-border trade, and dampen corporate earnings expectations—factors that typically weigh on equity sentiment.

Looking ahead, investors will watch for official statements from both governments, any signs of renewed negotiation, and trade data that might show early effects. The path of these talks could also influence currency markets and commodity prices, making Canada-related trade policy a key theme for global markets.
