Canada will impose 25% and 50% tariffs on roughly $20 billion in U.S. goods starting Sept. 8. Cheese, dairy, farm equipment, paper and seafood sit on the retaliation list — a direct answer to President Donald Trump's weekend duties on Canadian steel, aluminum and finished metals.

Finance Minister François-Philippe Champagne is set to release details Tuesday alongside three cabinet colleagues announcing worker supports. The list covers more than 700 U.S.-made products. Existing counter-tariffs on U.S. autos remain in place. Canadian officials say the goal is protection, not revenue.

What agriculture and machinery lines are in the firing line?

Dairy products including cheese, fish and seafood, appliances, and certain steel and aluminum derivatives carry 25% duties. Aluminum products, furniture, clothing and apparel sit at 50%. The 50% ceiling extends to farm equipment and pulp and paper — heavy inputs for U.S. processors, packers and manufacturers. Canada is the largest foreign buyer of U.S. automobiles, Prime Minister Mark Carney said Monday. Cars, auto parts and energy were excluded from Trump's latest round. Carney said Washington's auto-sector proposals would "gradually dismantle" Canadian production.

Ontario Premier Doug Ford went further Monday in an Associated Press interview. "Everything is on the table," Ford said, naming electricity and critical minerals as potential levers. "Trump underestimates Canada. We're all in."

Which U.S. states face the steepest exposure?

Iowa, Michigan, Ohio, Alaska and Maine. Iowa runs a deeply Canada-linked farm economy. Republican Sen. Susan Collins of Maine — a top Democratic target — said Monday on the campaign trail: "Imposing new tariffs on Canada is a mistake." Michigan's Democratic nominee Abdul El-Sayed called Trump "escalating a trade war with Canada for his own vanity" and labeled his GOP opponent, former Rep. Mike Rogers, a "rubber stamp."

Control of the U.S. Senate runs through the border states. Auto workers in Ohio, Kentucky and Alabama depend on Canadian demand for finished vehicles. Trump on Tuesday floated renaming Lake Ontario "Lake America," invoking his 2025 executive order that renamed the Gulf of Mexico.

What hits U.S. grocery and household budgets?

More than 550 Canadian products now carry U.S. duties. The White House list includes natural honey, tulip and lily bulbs, beet and onion seeds, plywood, vinyl flooring, paints, varnishes, luggage, sports equipment, toys, smartphones, video consoles, and toilet tissue. The Conference Board's consumer confidence index fell to 89.4 in August from 90.2 in July — the lowest reading in seven months — with pump prices over $4 a gallon.

Michael Howard II, owner of a Michigan furniture business, framed the squeeze in plain terms: "To say that we don't need Canada is just disingenuous. It's dishonest. And it's just absolutely not truthful."

What now?

Ford, after trading insults with Trump on Monday, softened Tuesday. The premier called the lake-rename talk "a lot of rhetoric" and urged the two countries to "get back to the table." Carney's government may shift from dollar-for-dollar matching to targeted retaliation aimed at shielding Canadian workers. Champagne and ministers will outline worker supports Tuesday morning. U.S. farm input costs, dairy export margins and the basis for wheat and corn all hinge on whether talks restart before the Sept. 8 trigger date.
