Collapse at midnight: the trade war is on
Minutes before the Friday-midnight deadline, Carney suspended negotiations, calling last-minute US changes "unfair, uneconomic." The USTR says Canada "upended" the deal with new demands. Either way: the 50% tariffs went live Saturday morning, Canada is retaliating dollar-for-dollar on ~$28B, and Carney is using the language of economic war. The deal that died would have cut steel/aluminum tariffs to 25%, autos to 15%, and killed the lumber levy — which measures how much was just lost. Our pre-committed odds rule now executes exactly as published Tuesday: Canada snaps to 45–50%.
The Scorecard — round two
| What we said (Aug 19) | What happened (Aug 22) | Grade |
|---|---|---|
| Three-path split: de-escalation 40% (modal), lands-then-rollback 30%, collapse-and-sticks 30% | Collapse happened — our modal path didn't. Second event in a row where the market-moving outcome wasn't our top-weighted branch. We flagged the pause as "a cliff, not a resolution" and the CAD's refusal to rally as "the tell" — both proved out. | Split missed, mechanism right |
| Pre-committed rule: "if Aug 22 collapses, Canada odds snap to 45–50%" | Executed exactly as published. No hindsight adjustment, no discretion — the rule we wrote Tuesday is the rule we applied Saturday. | Kept |
| Aug 13 original call: "lands in full and sticks" 40–50% — our top-weighted path before the pause | Three days late, this is now the live scenario. Across the full two-week arc, the original Tariff Bomb analysis — auto strike, unabsorbable math, Phase 1–4 timeline — is back in force, un-paused. | Re-armed |
| "The loonie fell on deal day — FX traders are pricing the risk that Saturday brings… a collapse that re-arms the tariffs" | That is precisely what Saturday brought. The currency market out-predicted the equity market, which closed Friday up 250 points pricing a deal. | Right |
How it fell apart
What happens now — the re-armed timeline
The Aug 13 Tariff Bomb clock restarts at Phase 1, with two differences. First, there's no more "watchful waiting" — exporters who bet on TACO just lost, and the behavioral shift (halting US-bound production scheduling, rerouting, layoff planning) should now come fast. Watch Windsor, Oakville and Alliston scheduling announcements this week. Second, retaliation is new: Canada matching dollar-for-dollar on $28B of US goods means Canadian consumer prices rise too — US-built vehicles, food, machinery — the consumer-price channel we mapped in our car-prices analysis now runs in both directions.
Legal challenges now have something to enjoin. A live, never-tested Section 338 tariff is a justiciable target in a way a paused one wasn't — expect filings within days, though commentary suggests this statute is harder to strike down than the IEEPA rounds. And the BoC calculus flips back: RBC's "hold through 2026" call was built on a de-escalating world; with a live trade war hitting Ontario's export engine, a September insurance cut is back on the table — which, ironically, is the one silver lining for mortgage-renewal households.
Monday morning matters: equities closed Friday priced for a deal. The TSX, auto suppliers (Magna, Linamar, Martinrea), and the loonie all face a repricing gap at Monday's open — the first hard data point on how much this collapse costs.
Updated odds
Canada — recession odds, next 12 months
The pre-committed rule from Aug 19, executed as written. A live 50% auto-sector tariff on an economy growing 0.7% with a shrinking population, plus retaliation raising domestic prices, is the adverse scenario from our August report — now activated, not hypothetical.
United States — recession odds, next 12 months
Canada's retaliation stings specific sectors (Midwest autos, agriculture) and adds a price impulse the Fed doesn't need, but the US macro story is still owned by payrolls, oil, and yields. Sep 4 jobs remains the decisive print.
The grind
Both sides dig in through the fall; the Tariff Bomb Phase 2–3 timeline (layoffs by Nov, regional recession by Feb) becomes the base case.
Market-forced re-deal
Monday's repricing, auto-sector shutdowns, and US consumer prices drag both sides back — the dead deal's terms get revived under a new name.
Import-ban spiral
Section 338(b) invoked against retaliation; the tail risk with no modern precedent. Low odds, unbounded damage.
