The record since

  • 8 Sep 26 No. 70 · revised to 97%
    Canada's retaliatory tariffs -- 15 to 50 percent on roughly $27.6 billion of US goods, including a doubling of steel/aluminum/iron duties to 50 percent -- took effect as scheduled on September 8, with Prime Minister Carney calling it a "dollar for dollar" response and no new US-Canada deal having intervened.

What would overturn it

A joint US-Canada announcement of a deal or a formal postponement before September 8 would overturn this; the tariffs actually entering into force on schedule would confirm it.

The verdict

Hit  Resolved 14 Sep 26.

Canada's counter-tariffs (roughly CA$27.6B, covering steel, dairy, appliances, ag equipment, pulp/paper, electronics at 15-50% rates) took effect at 12:01am on September 8, 2026 exactly as scheduled, with no US-Canada deal or postponement beforehand.

As logged at issue

Canada's September 8 retaliatory tariffs are likely to take effect on schedule rather than being averted by a last-minute deal, continuing the pattern of this month's collapsed talks -- though a fresh White House offer in the coming weeks, as happened before the August 19 US deadline, would delay them again.
