Canada's automotive sector is entering a period of extreme instability due to aggressive U.S. trade policies and the declining presence of American manufacturers. To combat this, former policy director Tom MacDonald has proposed a 25 percent global tariff to protect domestic production and diversify the market.

From the 1965 Auto Pact to the 1.2 Million Unit Slump

The historical foundation of the North American auto market was built on the 1965 auto pact, which created a mutually beneficial environment of lower prices and hihger wages. However, the subsequent adoption of the 1988 free-trade agreement and NAFTA fundamentally altered this landscape, allowing American capital to migrate south.

According to the report, Canadian production has plummeted from a peak of roughly three million units in 1999 to a projected 1.2 million by 2025. This systemic retreat of American capital has left the domestic industry vulnerable to the shifting geopolitical whims of the United States.

The Detroit 3's retreat from Oshawa, Brampton, and Oakville

The decline of the "Detroit 3"—General Motors, Ford, and Stellantis—is visible across Ontario's manufactring hubs. General Motors has halted electric van production in Ingersoll and cut shifts in Oshawa, while Stellantis closed its Brampton facility to move Jeep production to the United States, despite receiving hundreds of millions in Canadian subsidies.. Additionally, Ford's Oakville plant has remained largely idle since 2024.

The analysis notes that the production-to-sales ratio for these firms has fallen to a dismal 0.6. This indicates that General Motors, Ford, and Stellantis are selling far more vehicles in Canada than they are actually manufacturing within the country. This imbalance puts over 125,000 direct jobs and 427,000 indirect jobs at risk.

MacDonald's 25% global tariff to lure Toyota and Honda

To counter the loss of American investment, Tom MacDonald, a veteran of Canada-U.S. trade relations, suggests that Canada implement a 25 percent global tariff on all vehicle imports. This strategy is designed to create a powerful incentive for non-American automakers to maintain or expand their Canadian footprint to secure tariff relief.

By 2025, Toyota and Honda are expected to account for 76 percent of Canadian vehicle production, a stark contrast to the Detroit 3, who represent only 24 percent. As MacDonald suggests, focusing on these non-U.S. manufacturers could allow Canada to diversify its industrial base and reduce its dangerous over-reliance on a volatile American political climate.

Will a 25% tariff trigger a U.S. retaliation?

While the report presents a proactive strategy for Canadian survival, it does not provide a counter-argument from the U.S. government or the Detroit 3 manufacturers. The uncertainty surrounding a 25 percent global tariff remains a central concern, as the report does not address whether such a move would trigger immediate retaliation from the United States. Furthermore, it remains unclear how much political capital Canada has to fight specific "poison pill" tactics, such as U.S. Commerce Secretary Howard Lutnick's attempt to exclude trucks from tariff relief.
