What actually happened
The United States escalated its trade conflict with Canada from tariffs to targeted import bans. A White House proclamation says certain Canadian products will be excluded from import beginning September 29, while other covered goods remain subject to high duties. The move followed Canada’s September 8 countertariffs on $27.6 billion in U.S. imports. The immediate list focuses on selected dairy products, most alcoholic beverages and motorcycles, but the larger significance is the shift in method: two deeply integrated allies are now using market exclusion, not only tariffs, as leverage.
