The Tariff Ledger

Where the U.S. tariff wall stands, how the pain lands province by province, and what it means for the housing market.

The wall today - four layers, and a fifth on the way

Eighteen months in, this is no longer one tariff. It is a stack of overlapping regimes - Section 232 sectoral tariffs, longstanding lumber duties, and as of Monday, a new Section 338 action. Two days ago the White House signed proclamations adding a 50% duty on Canadian motor vehicles, dairy and alcohol, effective August 19.

Steel & aluminum
50%
Section 232. Steel has a tariff-rate quota - within-quota volume enters at 0%.
Autos & parts
25%
Section 232, on non-U.S. content. Excluded from the new Section 338 action (already covered).
Softwood lumber
~45%
10% Section 232 stacked on AD/CVD duties that hit 35.19% in summer 2025.
New · Section 338
50%
Signed July 20. Dairy, alcohol, motor vehicles. Effective Aug 19. About $20B of trade (5.2% of imports).
Energy & potash
Exempt
Carved out of Section 338; CUSMA-compliant energy flows largely untouched.
Where things stand

Ottawa has called the July 20 proclamations a direct violation of CUSMA but has not retaliated - Prime Minister Carney says Canada remains open to talks, while Ontario's Doug Ford is pushing for a matching response. The next four weeks before the August 19 effective date are the negotiating window.

How we got here

March 2025
First Section 232 steel and aluminum tariffs land; autos follow. The trade war opens.
Summer 2025
Lumber AD/CVD duties more than double to 35.19%. Canadian lumber production falls 8%; B.C. down 13%.
October 2025
10% Section 232 tariff added on softwood timber and lumber; 25% on cabinets, vanities and upholstered wood furniture.
June 2026
Section 232 steel and aluminum rates confirmed at 50%. Ottawa pledges $1.2B in lumber-sector support.
July 20, 2026
Three Section 338 proclamations signed - 50% on dairy, alcoholic beverages and motor vehicles. First use of this 1930 statute in the modern era.
August 19, 2026
Section 338 tariffs take effect unless a deal lands first.

The macro bill

GDP by end-2026
−1½%
Bank of Canada estimate vs. the no-tariff path (January MPR).
Peak GDP drag
−1.1%
Scotiabank's estimate of the peak level effect, landing late 2026.
Jobs epicentre
4 sectors
Autos, steel, aluminum, lumber - under 1.5% of GDP, but tens of thousands of jobs shed (RBC).

The striking asymmetry: the hardest-hit industries are small in GDP terms but geographically concentrated - which is exactly why the provincial and housing stories diverge so much. That's the next tab.

Province by province - concentration is the story

Ontario and Quebec carry effective tariff rates above 6% on their U.S.-bound exports because they make the things Washington is taxing. The energy provinces ship far more to the U.S. as a share of GDP, but energy's carve-out shields them. Click a bar or a chip to load the detail.

The housing market - a demand shock wearing a supply-shock costume

The intuition says tariffs raise construction costs and therefore prices. The evidence says the opposite is dominating: tariffs are hitting Canadian housing through jobs, incomes and confidence - a demand shock - and CMHC's mid-year update, released July 22, now expects prices to decline through 2026.

Five transmission channels

1
Jobs

Auto, steel, aluminum and lumber towns bear the layoffs - Windsor, Oshawa, Ingersoll, Sault Ste. Marie, Saguenay, the B.C. interior. Local housing demand follows local payrolls.

2
Income & confidence

High unemployment and modest income growth keep buyers sidelined nationally - the CMHC's core reason for the downgrade.

3
Construction costs

Mixed, and smaller than feared. U.S. duties keep more Canadian lumber at home, softening domestic prices; earlier counter-tariffs on steel and appliances cut the other way.

4
Interest rates

The offset. Tariff drag gives the Bank of Canada room to stay easy - the main cushion under prices and the reason CMHC sees recovery in 2027.

5
Population

Slower immigration compounds the demand hit, landing hardest on the condo and rental segments already glutted in Toronto and Vancouver.

My read

The tariff shock splits the market in two. Tariff-town Ontario and the condo markets of the GTA (−6.5% condos, ~2 years of inventory) and GVA (−15% peak-to-trough) absorb the real pain. Alberta, Saskatchewan and Atlantic Canada - shielded by the energy and potash carve-outs and still drawing interprovincial migrants - barely feel it. If the August 19 Section 338 tariffs stick, the auto-belt scenario worsens; if talks land a deal, the rate-cut cushion is already in place and 2027 turns up.

Sources & caveats

Everything above is assembled from public research published between September 2025 and July 22, 2026. Where provincial numbers weren't published, tier estimates are marked † and should be read as direction, not decimals.

Caveats

Provincial GDP impacts marked † are interpolated from Scotiabank's and RBC's qualitative rankings - four provinces have published anchors, six do not. Royal LePage and CMHC forecasts point in different directions on the national average; both are shown. The Section 338 tariffs are signed but not yet in effect - the housing outlook assumes they take effect August 19 as scheduled.
