Canada formally invokes CUSMA/USMCA dispute-settlement procedures against the new Section 338 tariffs within 30 days of the July 20 announcement, rather than confining its response to talks.
The wording, the opening probability, and the counter-signal below were fixed when this call was published. Updates revise the reading — never the record: the verdict is graded against the opening call.
The trajectory
The record since
The call stands as issued — no revisions.
What would overturn it
A formal Canadian filing under CUSMA/USMCA dispute-settlement chapters, or a Canadian retaliatory tariff list, within 30 days; continued Carney statements limited to seeking talks without a formal filing would resolve this false.
The verdict
Miss Resolved 24 Aug 26.
By Aug 19, Canada had filed no CUSMA/USMCA dispute-settlement case and instead pursued negotiations plus a matching retaliatory tariff list effective Sept 8 — the talks-confined path, not a formal legal filing.
Assumed Canada would escalate legally within 30 days; instead it stuck to talks-plus-retaliatory-tariffs, the exact 'confined to talks' path the counter-signal flagged.
As logged at issue
Carney called the new 50% Section 338 tariffs a 'direct violation' of CUSMA but so far has only committed to 'intensifying' talks, not retaliation or formal dispute action. We put it at roughly even odds Canada escalates to a formal dispute-settlement filing within 30 days rather than staying in pure negotiation mode.
