Tariffs on Canadian aluminum and crude oil aren’t just bad economics — they undermine the very industries they claim to protect.

In two new analyses, the Business Data Lab challenges six persistent myths driving misguided tariff policies:

Aluminum: Canada supplies over 60% of U.S. aluminum imports — supporting key sectors like automotive, aerospace, construction, and packaging. Yet in March, the U.S. reimposed a 25% tariff on Canadian aluminum. We break down three common myths about reshoring U.S. aluminum production and show why the integrated Canada–U.S. supply chain works for both economies.

Crude Oil: On his first day in office, President Trump declared a national energy emergency and promised U.S. energy abundance. But taxing Canada — the U.S.’s top crude oil supplier — does the opposite. We unpack three myths about crude oil tariffs and explain why swapping Canadian supply for U.S. or overseas alternatives isn’t simple, secure, or affordable.
