Canada is escalating the trade fight with the US, and the threats now aim straight at American factories and power grids — bad news for anyone hoping prices come down.

• Ontario premier Doug Ford says he will cut off US access to Canadian minerals the Pentagon needs for weapons and electronics.
• Ford is also threatening electricity exports again, after earlier slapping a 25% surcharge on power sent to Michigan, Minnesota, and New York.
• Trump has already set car tariffs at 25% and tariffs on Canadian steel at 50%, and traded insults with Ford in public.
• The US leans on Canada heavily for energy — most imported crude oil and nearly all imported natural gas come from there.
• Canadians are boycotting American products and skipping trips to the US, hitting tourism and retail.

Outlook: More tariff escalation looks likely, which means more upward pressure on prices for American buyers.
