The question is not whether Saturday produced a live U.S. duty. The question is which Canadian start date replaces Friday's failed talks.
September 8 is the next clock.
On Saturday, Associated Press reported that the United States imposed 50% tariffs on about $20 billion of Canadian products early that morning, and that Canada set Sept. 8 as the start of its retaliatory penalties after last-ditch negotiations failed (Associated Press).
Saturday we wrote that the pause expired. Sunday morning is the Canadian reply date.
The Live Rule Is Labor Day Week
Prime Minister Mark Carney said from Parliament Hill that Canada's dollar-for-dollar response starts Sept. 8, the Tuesday after Labor Day. He named U.S. steel, dairy, appliances, agricultural equipment, pulp and paper, and electronics, plus some products the U.S. previously targeted in Canada (Associated Press).
That is a calendar. It is not an HS-code list.
Carney said Canada had been willing to drop remaining steel, aluminum, and auto counter-tariffs if Washington substantially lowered its own, and to encourage provinces to restore U.S. alcohol sales. He said they asked too much and offered too little. U.S. Trade Representative Jamieson Greer said the administration had offered cuts on steel, autos, and lumber.
Those two statements can both be true. Neither one is a signed Canadian order.
Classification Beats Headline
AP put the U.S. slice at about 5% of what Canada ships south, two-way goods and services at $880 billion last year, and nearly 72% of Canada's goods exports to the United States (Associated Press).
If you export, price, or plan creative into those named sectors, that is the operating list.
Not Friday's optimism. Not the word retaliation as a mood. Not a premier's backing statement.
Inventory exposure by sector and ship date. What clears before Sept. 8. What clears after. Which claims and media plans assumed shelf continuity that is now contested.
A pause had a clock. The clock hit. Canada answered with another clock.
Name the owner. Name the sector list. Name the number that still holds if the HS codes land next week.
September 8 is not a new baseline. It is the rule until paper replaces it.
