Canada's counter-tariffs on American goods are scheduled to take effect at 12:01 a.m. on Tuesday, September 8, 2026. The national coverage has been about billions of dollars and negotiating positions, which is not much help if what you actually want to know is whether the dishwasher you were about to order is going to cost more next week. So this guide skips the analysis and goes straight to the questions people are asking, one at a time, with the short answer first and the detail underneath it.
A word on how to use it. The questions run roughly in the order you would think of them — timing, then what is on the list, then the categories you buy, then how origin works, then the border and online orders, then the money, then how long this lasts. Two warnings before you start: much of what circulates about tariffs is subtly wrong in ways that cost people money, and this situation is still moving, with the product list already amended once and the border agency's guidance not yet published. Last verified: Thursday, September 3, 2026 — we re-check this page on Friday and again on the morning the measures take effect.
