The record since

  • 17 Aug 26 No. 48 · revised to 68%
    Negotiators describe an emerging accord -- Canada dropping retaliatory auto tariffs and easing dairy/alcohol restrictions for US relief on Section 232 steel/aluminum and a Section 338 reprieve -- though talks remained 'not yet close' as of the weekend, moving the odds the 50% tariff is averted upward from the opening call.
  • 19 Aug 26 No. 50 · revised to 97%
    Trump announced a three-day pause on the 50-percent Canada tariffs Tuesday night, citing a deal pending document finalization — the tariffs did not take effect as scheduled Aug. 19, squarely confirming this call.

What would overturn it

Whether the tariff formally takes effect on Canadian goods August 19 versus a delay, framework deal, or exemption announced before then.

The verdict

Hit  Resolved 24 Aug 26.

Hours before the Aug 19 deadline, the US postponed the 50% Section 338 tariff to Aug 21 while talks continued, so it did not take effect on Aug 19 as scheduled (it later took effect Aug 22 after talks collapsed, outside this window).

As logged at issue

We think it's roughly even that a partial US-Canada trade framework heads off Washington's threatened 50% tariff before it takes effect August 19 -- watch whether the tariff lands on schedule as the signal talks failed.
