Canadas Counter-Tariffs Hit U.S. Midwest Hardest, Targeting Key Export States
Canada’s latest wave of retaliatory duties has hit U.S. exporters hard, especially in the Midwest and Great Lakes. Data from Scotiabank and Statistics Canada for September 2026 show Ohio tops the list with $2.3 billion of exports now subject to tariffs, followed by Illinois ($2.1 billion) and Pennsylvania ($1.8 billion). Wisconsin, long a dairy powerhouse, ranks second in the dairy‑specific list with $1.4 billion in covered dairy exports.
The tariffs, announced on September 8, 2026, carry rates of 15%, 25%, or 50% depending on the product. Industry Minister Mélanie Joly confirmed that Canada is targeting goods that are key to U.S. exporters in swing states, aiming to pressure Washington to revive stalled trade talks. The measure follows a broader dispute that erupted in February 2025 when President Donald Trump imposed near‑universal tariffs on Canadian and Mexican imports.
Dairy, steel, and other manufactured goods are the main sectors hit by the duties. Canada levies 25% on cheese and curd, and 50% on milk and cream—directly squeezing Wisconsin’s $1.4 billion dairy export stream. Steel and aluminum tariffs target Indiana, the nation’s leading steel‑making state, where $1.3 billion of exports now face duties.
The pattern of affected exports mirrors each state’s trade mix. Ohio and Illinois, with diversified manufacturing bases, carry the largest dollar totals because they export a broad array of goods that Canada has targeted. New York, California, and Texas also have more than $1 billion in covered exports, showing that the impact extends beyond the Midwest.
The tariffs carry a clear political angle. Pennsylvania and Wisconsin are swing states in the November 2026 midterm elections. By levying duties on goods from these states, Canada is applying economic pressure that could sway voter sentiment, echoing earlier Canadian actions during the first Trump administration, when Ottawa imposed duties on U.S. aluminum and steel to influence trade policy.
Beyond the immediate cost of tariffs, the trade war carries wider economic consequences. The U.S. Department of Commerce announced that additional 50% tariffs on critical Canadian industries will take effect in January 2027, raising the possibility of further Canadian retaliation. The cumulative effect could raise prices for U.S. consumers and disrupt supply chains that rely on cross‑border trade.
The dispute began when the U.S. imposed a 25% tariff on all Canadian imports, except energy, in February 2025. Canada responded with a 25% tariff on $30 billion of U.S. goods, expanding to $155 billion after three weeks. The U.S. Supreme Court struck down some Trump‑era tariffs in February 2026, but the new Canadian measures remain in force.
Trade analysts note that the U.S.–Canada relationship is the world’s largest bilateral trade partnership, with $916 billion in goods and services trade in 2023. The current tariffs threaten to disrupt that relationship, potentially affecting millions of jobs and billions of dollars in trade.
State officials are watching the fallout closely. Ohio’s Department of Commerce has issued guidance to exporters on navigating the new duties, while Wisconsin’s dairy lobby is lobbying for relief measures. The federal government has signaled support for affected exporters through tariff relief programs, though the extent of that aid remains uncertain.
The situation remains fluid. Canada’s counter‑tariffs will be reviewed in the next trade negotiations, and the U.S. has signaled a willingness to negotiate a new agreement. Until a resolution is reached, the states listed above will likely continue to feel the economic pinch of Canada’s retaliatory duties.
