Canada's new tariffs took effect today.⁣
⁣
Everyone wants to know if this is bad news.⁣
⁣
Short run: barely. Long run: worse than almost anyone is saying.⁣

A Deal With the United States Used to Be a Deal

The tariffs Ottawa and Washington traded today are small change. What we're actually spending is Canada's belief that we're a country worth building a factory next to.

Canada is one of our biggest trading partners.

Donald Trump is one of our biggest economic illiterates.

Now the rest of us are caught in the crossfire of an idiotic trade war that’s going to hurt regular people more than they’ll benefit.

Absent a dramatic last-minute development, Canada will impose retaliatory tariffs tomorrow ranging from 15% to 50% on a set of US imports, a move the US administration warned would trigger further tariffs and possible outright bans on some Canadian exports

Tariffs are a boxing match where both fighters punch their own people to land a hit on the other guy. Trump can hurt Canada, but only by hurting American consumers too. Carney can retaliate, but only by hurting Canadians. https://newsletter.platypuseconomics.com/p/why-dont-we-put-a-tariff-on-ohio

The trade war with Canada makes no economic sense. And most Americans agree. Polling shows they see Canadians as close allies, oppose the tariffs against them, and are actually cheering on Canadian retaliation. https://youtu.be/h8Fvnl0l7_8

Canada’s Retaliatory Tariffs Set to Take Effect as Trump Threatens to Escalate

New Canadian levies of up to 50 percent are expected to begin Tuesday, even as Washington warns of a new round of American tariffs.
