The strike that halted GM's production for 40 days could have a lingering effect on many suppliers in North America. It might also serve as a taste of things to come. Canadian supplier Magna International, for example, saw a US$500 million reduction in 2019 revenue.
Magna, which reports in U.S. dollars, says it now expects total sales this year of between $38.7 billion and $39.8 billion, a reduction of $1.3 billion on the top end of the range. A strike by UAW workers at General Motors plants across the United States lasted 40 days, costing suppliers.
