There is no separate Canadian auto industry. Plants there are all owned and run by global automakers whose North American operations are consolidated with their US and Mexican plants.

So far, at least, the shortages are unlikely to add to the tight supply or high prices, said Bernard Swiecki, director of research at the Center for Automotive Research, a Michigan think tank, which will have a delayed effect on pricing.

“It will inevitably be added onto the price increases, But the order of magnitude is weeks,” he said, adding that the impact will depend on how many plants have to shut down and for how long. However, he added, “the longer this goes on, the more the built in buffers of given components run out, the more plants will start going down.”

“This interruption on the Detroit/Windsor bridge hurts customers, auto workers, suppliers, communities and companies on both sides of the border that are already two years into parts shortages resulting from the global semiconductor issue, Covid and more,” said Ford in its statement. “We hope this situation is resolved quickly because it could have widespread impact on all automakers in the US and Canada.”

Stellantis reported that a number of its US and Canadian plants had cut short their second shifts Wednesday night but all its plants were running as of Thursday morning. It also had shortened the first shift Wednesday at the Brampton, Ontario plant that makes the Chrysler 300, Dodge Challenger, Dodge Charger.
