Trump is threatening a 50% tariff on Canada while his existing trade war unravels, and this is bad for American drivers, carmakers, and anyone worried about inflation.

• Tariff money is going into reverse — court-ordered refunds meant the US paid out more than it collected in June, so Trump needs a new revenue source.
• The stated reasons are odd: wildfire smoke damages and an 81% drop in American beer and wine sales to Canada.
• Canada is not backing down — it is signing new trade deals with Europe, China, and BRICS countries and letting cheap Chinese EVs under $25,000 into its market.
• The US quietly exempted energy and critical minerals, an admission it cannot function without Canadian crude, steel, and aluminum.
• Canada is planning a new pipeline to ship a million barrels a day to Asia instead, which would push US gas prices higher.

Outlook: With the Iran conflict pushing oil back toward $90 and government bond yields above 5%, a second front against Canada risks higher prices at the pump and at the store.
