The Globe and Mail reports in its Saturday edition that some Canadian grocery chains and food companies, including Nova Scotia-based High Liner Foods, are investigating their supply chains after a group of journalists found seafood processed using forced labour in China is being shipped to the United States, Europe and Canada. The Globe's Tavia Grant and Lindsay Jones write that journalism non-profit the Outlaw Ocean Project's four-year investigation, published in The Globe earlier this month, said at least 10 large seafood companies in China have used more than 1,000 Uyghur workers since 2018. Seafood from these plants, it said, was purchased by major importers -- including High Liner, one of the largest seafood companies in Canada and a major supplier in the U.S. Shortly after Outlaw Ocean first published the story in early October, High Liner launched its own investigation and cut ties with the seafood plant in China that is alleged to have used Uyghur labour. Albertsons, one of the largest U.S. grocery store chains, which owns Safeway, has stopped purchasing flounder and yellow tail sole from High Liner until it completes its own investigation. Walmart Canada told The Globe it is investigating the matter.
