Tariffs, Uncertainty, and a Fragile Recovery: What the CUSMA Standoff Means for Canada

Canada's economy entered the summer of 2026 in a place it hasn't been since the pandemic: technically in recession. Real GDP contracted at an annualized 1.0% in the fourth quarter of 2025 and a further 0.1% in the first quarter of 2026 — two consecutive quarterly declines, the textbook definition of a technical recession, and Canada was the only G7 economy to shrink in that final quarter of 2025. Against that backdrop, the collapse of the mandatory CUSMA review and a fresh round of U.S. tariffs land on an economy that has very little cushion left to absorb them.

A review that didn't renew
CUSMA (known as USMCA in the U.S. and T-MEC in Mexico) came with a built-in trigger: a mandatory joint review every six years, the first of which fell due on July 1, 2026. Under the agreement's terms, the three parties could have extended it for another sixteen years with minor amendments. Instead, the United States declined to renew CUSMA in its current form, pushing the process into an annual review cycle that could, absent a breakthrough, run until the agreement's outer expiry in 2036.

That outcome followed a rocky lead-up. Trade talks between Ottawa and Washington broke down entirely in October 2025 and didn't resume until March 2026. In between, the U.S. Trade Representative's office released its National Trade Estimate report flagging a long list of grievances with Canadian policy, and Canada's former chief CUSMA negotiator, Steve Verheul, has said publicly he expects negotiations to drag on past the U.S. midterm elections this fall — possibly into 2027. As one legal analyst put it, the real danger isn't that CUSMA formally terminates, but that it functions as though it might, indefinitely.

The tariffs kept coming
Even before the review deadline passed, sectoral tariffs on Canadian goods had been climbing steadily through 2025 and into 2026: 50% on steel, aluminum, and copper; 25% on automobiles and auto parts (with partial CUSMA-linked exemptions); 10% on softwood lumber and timber, on top of pre-existing anti-dumping and countervailing duties that bring the combined softwood rate above 35%; and a 12.5% levy tied to a forced-labour enforcement dispute added just last month.

Then, on July 20, 2026 — three weeks after the review deadline passed without a deal — the administration went further. Using the rarely invoked Section 338 of the Tariff Act of 1930 (a provision with no recorded use since 1949), President Trump signed three proclamations imposing an additional 50% tariff on specific categories of Canadian goods: automobiles, alcohol, and dairy-linked products, covering items as varied as wine, cement, and hockey sticks. Notably, the White House said these tariffs apply "regardless" of whether the goods qualify under CUSMA — a departure from most previous tariff actions, which had carved out exemptions for USMCA-compliant trade. The administration framed the move as retaliation for Canadian measures like the removal of U.S. alcohol from provincial shelves and caps on U.S. auto exports into Canada. A separate threat looms in the background too: Trump has said he would consider tariffs as high as 100% on Canadian goods if Canada were to pursue a free trade deal with China, something Prime Minister Mark Carney has already ruled out.

Why this hits harder in a recession
Tariffs are disruptive in any environment, but Canada is absorbing them at a moment of unusual economic fragility, which changes how the medium- and long-term math works.

Investment freezes first. Business capital investment has now fallen for five consecutive quarters, and economists point squarely at tariff and CUSMA uncertainty as the driver. This is the classic "invisible tax" effect: firms don't need a tariff to actually bite to pull back — the mere possibility that the rules could change again in six months is often enough to delay a plant expansion, a hiring plan, or a supply-chain investment. In a recession, this kind of hesitation is more costly than in a boom, because there's no offsetting momentum elsewhere in the economy to absorb the slack.

Export composition is shifting, not diversifying. Canadian goods exports to the U.S. fell 5.8% in 2025. On paper, exports to the rest of the world jumped 17.2%, and the U.S. share of Canadian exports has fallen to 71.7% — its lowest level since the early 1980s. But a large share of that "diversification" reflects a surge in gold shipments rather than Canadian firms genuinely building new customer bases abroad. Real diversification — the kind that would meaningfully insulate Canada from U.S. trade policy swings — takes years of relationship-building, logistics investment, and regulatory alignment that hasn't happened yet at scale.

Sector concentration means uneven pain. Roughly 90% of Canadian steel and aluminum exports go to U.S. buyers, and the auto sector's cross-border supply chains mean tariffs on parts ripple through assembly plants on both sides of the border. Ontario's auto sector, B.C. and Quebec's forestry industry, and Prairie agriculture are disproportionately exposed to whichever sectoral tariff line moves next — meaning the recession's regional footprint is likely to widen rather than stay contained to trade-exposed provinces alone.

Monetary policy has less room to help. The Bank of Canada has held its policy rate at 2.25% through four consecutive meetings, balancing tariff-driven growth weakness against inflation that's ticking higher — partly a byproduct of tariffs raising input costs. That's a narrower path than the Bank had in previous downturns, when there was more room to cut rates aggressively without stoking inflation.

The Bank of Canada's own base-case projection assumes CUSMA-related uncertainty gradually fades through 2026 and estimates the tariff shock will leave GDP roughly 1.5% below its pre-tariff trajectory by year-end, with about half of that gap coming from permanently lower potential output — not just a temporary dip. If the annual-review limbo drags on instead of resolving, as the U.S. ambassador to Canada has suggested it might into 2027, that assumption doesn't hold, and the uncertainty tax keeps compounding rather than fading.

Reasons the picture isn't purely bleak
It's worth resisting a straight-line doom narrative. Several forecasters, including TD Economics and Capital Economics, argue the technical recession may already be shallow and short-lived: much of the Q1 contraction traced to a pullback in government spending rather than broad private-sector weakness, household consumption actually rose in the quarter, and early estimates point to a rebound in oil, gas, and mining activity. Elevated oil prices are providing a genuine offset for Canada as a net energy exporter, even as they raise costs for households. And on a per-capita basis, GDP actually ticked up in the first quarter — a reminder that some of the headline weakness reflects a shrinking population under tighter immigration targets rather than a collapsing economy.

What comes next
The CUSMA relationship is now formally in an annual-review state rather than settled for the next sixteen years, and Canada's trade minister has said discussions with Washington on the sectoral tariffs affecting steel, aluminum, autos, and lumber are continuing. Three broad paths remain open: a negotiated extension that unwinds some of the current tariff structure, a prolonged limbo of yearly reviews that keeps uncertainty elevated as a permanent feature of the economic outlook, or — the most disruptive but least likely near-term outcome — a formal withdrawal from the agreement by any of the three parties on six months' notice.

For a Canadian economy already running with less cushion than usual, the practical difference between those paths isn't abstract. It's the difference between businesses that start investing again and businesses that keep waiting to see what happens next.
