The Globe and Mail reports in its Friday edition that High Liner Foods learned the hard way about risks lurking in its supply chain. The Globe's Rita Trichur writes that the Nova Scotia-based seafood company, which began scrutinizing its suppliers this fall, severed ties with Yantai Sanko Fisheries, a plant in China that is alleged to have used Uyghur forced labour. It took action after a journalism non-profit, the Outlaw Ocean Project, published a report that found High Liner was among the North American importers purchasing Chinese seafood processed by exploited workers. Human rights groups are now urging the federal government to sanction seven Chinese businesses for systemic abuse of Uyghur workers in China's seafood industry. Sanctions are a start. The revelations, which prompted other food companies and retailers to probe their vendors, should also serve as a wake-up call for the broader business community about the potential for forced labour to be concealed in their supply chains. Business leaders cannot afford to be caught flat-footed by the legal and reputational risks. Canada's Modern Slavery Act takes effect in the new year and the Trudeau government promises more action on slavery and child labour.
