**Summary**: Canadian PM Mark Carney says he tore up a US trade deal after last‑minute US changes, and Canada will impose retaliatory tariffs starting September 8. This marks a clear breakdown in North American trade negotiations and raises the prospect of a tit‑for‑tat tariff cycle affecting cross‑border goods flows and FX.

## Detail

1) What happened:
Multiple reports confirm that Canada–US trade talks have collapsed. PM Mark Carney publicly stated the agreement became untenable after Washington altered terms at the last minute to bar Canada from negotiating with other countries, prompting Ottawa to walk away. Canada has now signaled it will implement retaliatory tariffs on US products beginning 8 September. Details on product coverage and rates are not yet published, but framing suggests a politically salient and broad response.

2) Supply/demand impact:
This is primarily a trade and FX shock rather than a direct physical commodity disruption. However, Canada is a major exporter of crude, natural gas, electricity, autos, fertilizers, lumber, and agricultural products to the US. Depending on tariff design, there could be margin compression along integrated cross‑border value chains (autos, steel, aluminum, agriculture) and potential re‑routing of some flows over time.

In the near term, physical flows of energy and bulk commodities are unlikely to be immediately curtailed; they are typically carved out or face lower tariffs because of mutual dependence. But if US counter‑retaliation targets Canadian metals, autos, or agriculture, it could dampen capex and output growth in those sectors and marginally weigh on medium‑term supply.

3) Affected assets and direction:
USD/CAD is likely to weaken CAD on growth and trade‑uncertainty concerns, though some safe‑haven demand for US assets could offset. Canadian equities with high US revenue exposure (autos/parts, forestry, industrials, possibly aluminum/steel) face downside. North American steel/aluminum and auto names could underperform globally. If tariffs touch agriculture, CBOT grains and canola could see volatility as traders reassess trade flows, though a sustained price level shift will hinge on product specifics.

4) Historical precedent:
The 2018–2019 US–Canada steel and aluminum tariffs and NAFTA/USMCA renegotiation episodes drove 1–3% intraday moves in USD/CAD and sector rotations in North American equities, with limited direct commodity supply effects but elevated volatility around headlines.

5) Duration:
Impact is medium‑term. Tariffs scheduled for 8 September create a clear calendar focal point. Unless reversed quickly through renewed talks, markets will begin to price a more persistent deterioration in North American trade relations, with a structural risk premium in CAD and in cross‑border exposed sectors, even if core energy and grain flows continue.

**AFFECTED ASSETS:** USD/CAD, Canadian equities (TSX, especially autos/industrials), North American steel and aluminum equities, North American auto OEMs and parts suppliers, Canola futures, CBOT wheat futures, US and Canadian sovereign CDS (marginal sentiment impact)
