Carmakers have temporarily shut down some plants in the US and Canada as truck drivers in big rigs blocked critical border crossings as part of a growing protest against Covid-19 mandates, cutting off the flow of car parts and other goods between the two countries.
The Freedom Convoy protests, which converged last month in Canada’s capital city of Ottawa, have spread to the Ambassador Bridge that connects Detroit in the US and Windsor in Canada, where traffic was snarled for a fourth day on Thursday.
The disruptions illustrate how the protests have ballooned in recent weeks, spreading beyond Canada’s borders and affecting commerce with its North American neighbour and most important trading partner.
