U.S.-Canada Trade War: Mark Carney’s team walked away from stalled talks, and the U.S. moved ahead with 50% tariffs on about $20B of Canadian goods—followed by Trump’s threat to raise autos, auto parts and steel to 50% starting Jan. 1, 2027—while Canada vows “dollar-for-dollar” retaliation from Sept. 8; economists warn the hit could mean tens of thousands of job losses, with Ontario and Quebec seen as hardest affected. Ontario Pushback: Doug Ford told the AP Ronald Reagan would be “throwing up” over Trump’s policies and said Ontario is ready to cut off electricity and critical minerals to the U.S. if the fight worsens. Food Costs Warning: A new analysis argues tariffs could drive higher grocery prices for lower-income households and create knock-on “price umbrella” effects that last beyond the initial tariff list. Local Impacts: Agriculture leaders urged both sides to keep USMCA talks going as dairy, lumber and honey face new duties; flower growers warn of a cash-flow crisis because long-cycle crops can’t be easily redirected. Public Safety: Ottawa police are investigating the death of a 27-year-old woman in Lowertown as a femicide after a Quebec crash probe. Infrastructure: Canada is expanding high-speed internet access in Ontario, targeting hundreds of underserved homes. Other Canada Notes: Nacel Canada is seeking host families for Brazilian exchange students in Saskatchewan; SIU cleared a Toronto officer in an Etobicoke crash that injured an 18-year-old.
