Carney Set to Announce Historic Investment in Canadian Manufacturing.

U.S. Trade Representative Jamieson Greer said Tuesday there are no trade negotiations with Canada underway and that restarting them is Canada's responsibility.

• $20 billion in Canadian goods now face 50% U.S. tariffs.
• Canada's retaliatory tariffs on $20 billion of U.S. goods take effect Sept. 8.
• Greer said Canada's last-minute asks on heavy trucks tanked the deal.
• Canada says the U.S. made the last-minute changes, including truck tariff terms.

Why it matters: The two sides offer conflicting accounts of why talks collapsed Aug. 21, leaving no deal and a one-week window before tariffs escalate further.

• Royal Bank of Canada warned a no-deal scenario could reduce GDP by 0.4%.
• University of Calgary economist Trevor Tombe estimated a full trade war could cost up to 90,000 Canadian jobs.

Where they split: The core dispute is who caused talks to collapse: Greer says Canada rejected a finalized deal with eleventh-hour demands; Carney says U.S. negotiators changed terms at the last minute.

• Greer told Fox News the U.S. is preparing measures responding to Canadian retaliation.
• Canadian lawmakers are weighing pulling back on an order for 88 U.S.-made F-35 jets.
• Will either side blink before the Sept. 8 tariff deadline, and who would make the first move?
• How far will Canada pursue alternative trade partners if U.S. talks remain stalled?
• Will the U.S. follow through with additional retaliatory measures after Sept. 8?
