There is a map Canadians need to see.
It is not the electoral map. It is not a map of pipelines, oilfields or provincial borders.
It is the map of Donald Trump’s latest tariffs.
Put that map beside the results of Canada’s 2025 federal election and something remarkable appears.
The provinces facing the greatest exposure from Trump’s newest 50 percent tariff package are British Columbia, Quebec and Ontario.
Those same three provinces supplied
134 of Mark Carney’s 169 Liberal MPs.
Meanwhile, Alberta and Saskatchewan, two provinces that overwhelmingly rejected Carney’s Liberals, are barely touched by this particular round.
Then read the tariff proclamations. Look at what Washington included, what it left out, and how closely the White House was tracking the actions of individual provinces.
The blast radius has a shape.
And politically, that shape matters.
THE MAP NOBODY IS LOOKING AT
Trump’s new Section 338 tariffs impose an additional 50 percent duty on certain Canadian goods. That does not mean half of everything Canada sells to America suddenly faces another 50 percent tariff.
The product list matters.
Because different provinces export different things, the regional consequences are wildly uneven.
University of Calgary economist Trevor Tombe calculated that
13.7 percent of British Columbia’s exports to the United States are exposed to the new tariffs. Quebec sits at 10.8 percent and Ontario at 9 percent. Saskatchewan and Alberta are roughly 1 percent each. (

British Columbia’s direct exposure is therefore roughly fourteen times that of Alberta or Saskatchewan.
Quebec’s is roughly eleven times greater.
Ontario’s is roughly nine times greater.
This is not one tariff bomb falling evenly across Canada.
NOW PUT THE ELECTION MAP UNDERNEATH IT
Mark Carney’s Liberals won
169 seats in the 2025 federal election. Elections Canada’s official results show that Ontario supplied
70 Liberal MPs, Quebec
44, and British Columbia
20. (
Elections Canada)
That is 134 seats.
Nearly four out of every five Liberal MPs came from those three provinces.
Now look west.
Alberta elected two Liberals.
Saskatchewan elected one.
Three seats combined. (
Elections Canada)
There it is.
The three provinces providing almost four-fifths of Carney’s caucus sit at the top of the new tariff exposure table.
Two of the provinces where Carney is weakest sit near the bottom.
Ontario and Quebec alone supplied
114 of Carney’s 169 seats.
Without those two provinces, there is no Carney government.
That is where this stops being merely an economics story.
It becomes a political one.
THE PRAIRIES DIDN’T JUST GET LUCKY
Why are Alberta and Saskatchewan so lightly exposed?
The answer is sitting in Trump’s own tariff policy.
The White House explicitly exempted
energy and potash from these Section 338 tariffs. It also excluded products already subject to Section 232 tariffs and certain other goods, including fish and critical minerals. (
