Randall Denley: It's not worth a trade war to save Ontario's foreign-owned car plants - National Post

It’s easy to see why Ford, elected on a promise of job protection, would champion the highly visible auto sector, but is this the right battle to fight?
The so-called Canadian vehicle-assembly industry is foreign-owned and dependent on a steady flow of government subsidies. No matter how much federal and provincial governments “invest” in the industry, Ontario’s auto plants are always just one corporate or political decision away from pulling up stakes.
Despite government assistance, vehicle assembly in Ontario has declined steadily from its 1999 peak of just over three million vehicles to 1.2 million in 2025. The share produced by America’s Big Three companies has atrophied from half the Canadian total historically to just under one-quarter now.

Ontario’s auto industry relies on the best possible trade scenario: tariff-free access to the American market. The five manufacturers who build cars here ship 92 per cent of them to the U.S.
That American access is the reason that Ontario has an auto industry, but it seems extremely unlikely to continue. Possible American tariffs range from 15 to 50 per cent. The higher number would crush the industry, the lower one would enable it to linger for a while.
Auto assembly has had a great run in Ontario, but its future seems limited. Fighting to assemble foreign cars isn’t in sync with Prime Minister Mark Carney’s vow to make Canada more economically independent. The auto-assembly industry is a symbol of dependence on the U.S., not one of national pride.
Rather than trying to protect an industry of the past, Canada and Ontario need a new approach that preserves the part of the auto industry that is truly Canadian.
Auto assembly and parts manufacturing are often lumped together, but the situation with auto parts is quite different. Canadian-owned companies lead the way. The auto parts sector produces more jobs and economic impact than auto assembly does. In 2024, there were about 71,400 auto-parts workers in Canada, most of them in Ontario. Vehicle assembly employed 46,700 workers and had a GDP contribution of $7.8 billion versus $11.3 billion for auto parts.
