How far will the US-Canada trade war go?

# Analysis The collapse of US-Canada trade negotiations threatens to destabilize the North American economy in ways that extend far beyond the two countries' bilateral relationship. The integrated supply chains spanning automotive manufacturing, energy production, and agriculture mean that tariffs will rapidly translate into higher consumer prices for Americans and Canadians alike, while forcing manufacturers to either relocate operations or absorb substantial costs. A full-scale trade war could trigger job losses in border regions and key industrial sectors, particularly in the automotive industry where cross-border components routinely traverse the US-Canada border multiple times before reaching final assembly. Beyond immediate economic pain, prolonged trade tensions risk undermining the regional competitiveness of North American companies against Chinese and European competitors, potentially ceding market share in global sectors where integrated North American production has long been a competitive advantage.
