The U.S. Canada Trade War Casts a Much Longer Shadow | Diving In
Sep 8, 2026 · 26m
Summary
Justin Wolfers analyzes the new US-Canada trade war, noting that while the immediate economic impact is minimal, the long-term damage to integrated supply chains and North American competitiveness is significant. He argues that Trump’s erratic rhetoric and threats have turned a trade dispute into a sovereignty issue, prompting a Canadian consumer boycott and eroding trust in US reliability. Wolfers advises Prime Minister Carney to slow the escalation spiral by delaying retaliatory tariffs, while urging Trump to stop insulting allies to preserve American economic interests.
