The insane thing is that when an asshat with no authority renames the Gulf of Mexico, Google and Apple Maps immediately modify their maps to appease. So when will they update Lake Ontario? Fuck these sycophants!

If Mark Carney 🇨🇦 pledged to give all tariff revenue back to all Canadians in equal shares (by a tax credit say), the tariffs would be revenue-neutral and not effectively inflationary. And US products would be even more (relatively) injured (because Canadians would have extra $ to buy alternatives!)
