Trump says the US doesn’t need Canada. America’s economy says otherwise.

Despite Trump's "we don't need Canada" line, the U.S. relies heavily on Canada for energy and materials — roughly 4 million barrels of oil a day (nearly 20% of U.S. petroleum), most aluminum, >80% of potash, auto parts and much of cross‑border electricity.
The White House has slapped 50% tariffs on Canadian aluminum and threatened 50% tariffs on cars/parts — moves that could raise costs for American drivers, farmers and automakers and become a political flashpoint before midterms.
Canada has some leverage (potash, energy, electricity for rising AI demand), but using it risks hurting Canadian producers and political unity — underlining how deeply intertwined the two economies are.
