Open  Resolves by 9 Sep 26 — graded at the weekly Reckoning against the criteria above, and recorded here.

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.
