Look at the map.
Canada is the No. 1 export market for 27 U.S. states.
Maine sends 41% of its exports to Canada.
Michigan sends 39%.
Wisconsin sends 31%.
That’s not a small customer.
That’s a major piece of some state economies.
And Canada’s new retaliation is aimed directly at the kinds of products those states produce.
Starting September 8, Canada will impose 15%, 25% and 50% tariffs on roughly $27.6 billion of U.S. goods.
Steel.
Dairy.
Appliances.
Farm equipment.
Pulp and paper.
Electronics.
Now think about what happens to a Michigan manufacturer that sells heavily into Canada.
It doesn’t need the U.S. to enter a recession.
It just needs Canadian buyers to say:
“We’ll buy it somewhere else.”
Then the manufacturer has a choice.
Eat the tariff.
Raise the price and lose demand.
Or cut production.
None of those are great for workers.
And the damage is already showing up somewhere else.
Canadians made 29.1 million trips to the U.S. in 2025, down from 39 million in 2024.
That’s a 25.4% collapse in travel.
Canadian spending in the U.S. fell another $2.3 billion.
That means the hit isn’t just factories.
It’s hotels.
Restaurants.
Retail.
Gas stations.
Airlines.
Border towns.
Tourist destinations.
And this is where I think the map becomes much more important than the national GDP number.
A $20 billion tariff fight can look tiny next to an $879.9 billion U.S.-Canada goods relationship.
But concentrated in the wrong states and industries, it can be enormous.
Canada buys roughly one-tenth of all U.S. exports.
And 27 states have Canada as their biggest foreign customer.
So I wouldn’t watch this by asking:
“Will Canada cause a U.S. recession?”
I’d watch:
Michigan factory orders.
Maine exports.
Wisconsin manufacturing.
Farm equipment sales.
Steel shipments.
Border traffic.
Canadian hotel bookings.
Canadian retail spending.
That’s where the tariff war gets real.
The national number can look fine while individual states start getting crushed.
