A Canadian dealership can still be full of familiar American nameplates while containing fewer vehicles that were actually built in the United States. That distinction is becoming increasingly important. A new preliminary analysis from CarGurus finds sales of U.S.-assembled vehicles in Canada fell 24% from March 2025 through the end of September 2026, while listing inventory also declined. Separate J.D. Power Canada data points in the same direction, showing the U.S. share of Canadian new-vehicle sales falling sharply in the first half of 2026. The shift is less about one brand or one consumer trend than a rapid rewiring of North American vehicle sourcing, as tariffs, remission rules and factory footprints increasingly determine which models Canadian dealers can economically stock.
The 24% Drop Measures Assembly Location, Not Brand Loyalty
The headline figure comes from a preliminary CarGurus analysis of vehicles identified with U.S. vehicle identification numbers. Kevin Roberts, CarGurus’ director of economic and market intelligence, said sales of U.S.-assembled vehicles in Canada were down 24% from March 2025 through the end of September 2026, while listing inventory also appeared to decline. Because global brands build vehicles in American plants, the measure tracks factory location rather than badge nationality.
That distinction makes the result difficult to explain as a simple consumer boycott. J.D. Power Canada has separately recorded a large loss of market share for U.S.-built vehicles, while analysts point to changing supply routes and tariff exposure. Canadians may therefore encounter fewer U.S.-assembled choices before personal preference enters the decision. The data shows the sales mix moved; it does not, on its own, establish why every shopper or automaker changed course.
U.S.-Built Vehicles Are Falling Faster Than Canada’s Overall Market
J.D. Power Canada data provides a broader benchmark. Vehicles assembled in the United States accounted for 28.4% of Canadian new-vehicle sales in the first half of 2026, down from 35.4% in the same period of 2025. That seven-percentage-point drop is significant in a market where U.S.-built vehicles have long been the largest source.
The overall Canadian market weakened much less dramatically. DesRosiers Automotive Consultants estimated about 950,000 new light vehicles were sold in the first six months of 2026, down 2.6% from 976,000 a year earlier. That contrast matters: U.S.-assembled vehicles lost far more ground than the market as a whole. The numbers support the view that sourcing changes, not simply weaker demand, are reshaping the mix. Canadians are still buying close to a million new vehicles in six months, but a smaller share is arriving from American plants.
The Turning Point Came With the 2025 Auto Tariffs
The policy shock arrived quickly. On March 26, 2025, President Donald Trump proclaimed a 25% U.S. tariff on imported automobiles under Section 232, with the vehicle tariff taking effect April 3. For vehicles qualifying under the Canada-U.S.-Mexico Agreement, importers could document U.S. content so the tariff applied only to non-U.S. content. Canada answered with an automobile countermeasure, effective April 9, targeting vehicles originating in the United States.
Canada’s rules also contain a North American-content adjustment. U.S. vehicles that do not qualify for CUSMA treatment face the 25% surtax on their value for duty, while qualifying vehicles can exclude eligible Canadian and Mexican content from the calculation. Even with those adjustments, the economics of moving a U.S.-assembled vehicle into Canada changed. For automakers with alternative factories, the tariff created a reason to reroute Canadian supply instead of absorbing a new cross-border cost.
Ottawa’s Remission System Created Two Different Tariff Realities
Canada did not apply the counter-tariff equally in practical terms. In April 2025, Ottawa created a performance-based remission framework allowing qualifying manufacturers that build vehicles in Canada to import a set number of U.S.-assembled, CUSMA-compliant vehicles without paying the counter-tariff. Eligibility was tied to maintaining Canadian production and investment. The framework was renewed for imports from April 9, 2026 through April 8, 2027.
The quotas are confidential, but Ottawa has shown that access can be reduced. In October 2025, the government cut General Motors’ annual remission quota by 24.2% after production reductions in Oshawa and Ingersoll, and cut Stellantis’ quota by 50% after it cancelled production plans for Brampton. That makes the program more than a tax exemption. It is an industrial-policy lever: Canadian factory commitments can influence how many U.S.-built vehicles a company can bring into Canada without the retaliatory tariff.
Automakers Without Canadian Plants Took the Hardest Hit
The remission system’s impact becomes clearer when automakers are split into two groups. Among Ford, General Motors, Honda, Stellantis and Toyota — the five manufacturers with Canadian vehicle assembly operations — U.S.-built products represented 45.2% of their Canadian sales in the first half of 2026. That was 3.1 percentage points lower than a year earlier.
The picture differed for automakers without Canadian assembly plants. For that group, U.S.-made vehicles accounted for just 4.9% of Canadian sales, down from 17.7% a year earlier. The contrast helps explain why the broader decline should not automatically be read as a rejection of Detroit brands. Much of the adjustment has come from global automakers deciding which factories should serve Canada. DesRosiers managing partner Andrew King has said the shift is likely driven more by sourcing changes designed to avoid tariffs than by collapsing Canadian demand for U.S.-built vehicles.
Familiar Models Were Paused, Pulled or Sourced Elsewhere
The shift becomes tangible at the model level. Mazda announced in April 2025 that production of the Alabama-built CX-50 for Canada would be suspended beginning May 12 while U.S. output continued. Nissan later paused U.S. production of the Pathfinder, Murano and Frontier for Canada, describing the move as temporary while the tariff dispute continued. Fewer tariff-exposed units were being sent north.
Other manufacturers made similar adjustments. Volvo withheld the South Carolina-built EX90 from Canada for the 2026 model year while evaluating tariffs. Industry reporting shows Tesla shifted Canadian sourcing from U.S. production toward Germany and China, while Subaru leaned more heavily on Japan. These choices can quickly change sales statistics. A shopper may still want the same brand, body style or powertrain, but the country stamped on the build sheet can change because an automaker found a less costly route into Canada.
Mexico, Japan and South Korea Are Filling the Space
As the U.S. share contracts, other assembly countries are gaining ground. J.D. Power Canada figures show Mexican-built vehicles accounting for 22.2% of Canadian new-vehicle sales in the first half of 2026, up from 18.3% a year earlier. Japan rose to 16.6% from 13.7%, while South Korea increased to 15.6% from 14.6%. Those are meaningful shifts across Canada’s market.
Mexico’s rise is notable because it sits inside the same CUSMA trading bloc. J.D. Power data cited by Automotive News indicates Mexico’s share was 13.7% five years earlier, meaning its role in Canadian showrooms was expanding before the tariff fight. Robert Karwel of J.D. Power Canada has said Mexico could challenge the United States as Canada’s largest vehicle source if conditions continue. For manufacturers with flexible production networks, the incentive is straightforward: supply Canada from plants that do not trigger the U.S.-vehicle counter-tariff.
Canadian Assembly Has Not Automatically Been the Winner
A decline in U.S.-built vehicles does not mean Canadian factories captured the lost share. J.D. Power Canada data shows Canadian-assembled vehicles represented 11.5% of new-vehicle sales in the first half of 2026, down from 12.6% a year earlier. Industry reporting points to plant changeovers and lower output as factors. The market has become more internationally diversified rather than simply more Canadian.
Vehicle manufacturing remains an industrial pillar. Ottawa says Canada produced about 1.3 million light-duty vehicles in 2024 and exported roughly 1.1 million to the United States. The federal government estimates the auto industry supports about 125,000 direct jobs, around 80% in Ontario. Canada’s remission framework was designed to protect that footprint by linking tariff relief to production and investment. Yet the 2026 sales mix shows the challenge: discouraging U.S. imports does not automatically create enough domestic output to replace them.
The Bigger Risk Runs Through Both Sides of the Border
Canada is not a minor outlet for U.S. factories. A 2026 Congressional Research Service report identified Canada as the top destination for U.S. vehicle exports in 2025, accounting for 32% of export value and 21% of volume. Canadian data shows tight integration: in 2024, Canada exported $44.4 billion in finished vehicles to the United States while importing $35.6 billion.
That makes the decline in U.S.-assembled sales a North American production story, not only a Canadian retail story. Fewer Canada-bound vehicles can mean less output for American assembly plants, suppliers and logistics networks, while tariffs on Canadian-built vehicles pressure factories north of the border. CarGurus and J.D. Power do not establish that tariffs are the only cause, but they show factory sourcing has changed materially since spring 2025. If incentives remain, Canadian showrooms may keep changing even when familiar badges remain.
