The Globe and Mail reports in its Thursday edition that Ottawa's regulatory review of Anglo American's proposed acquisition of Teck Resources will test the more stringent rules brought in the aftermath of an earlier high-profile takeover involving the Canadian miner. The Globe's Niall McGee writes that London-based Anglo plans to buy Teck in an all-stock deal worth $20-billion (U.S.) that could see one of Canada's last remaining major critical-minerals miners fall into foreign hands. For the deal to close, it must be approved by the federal government. Industry Minister Mélanie Joly will scrutinize the transaction for national-security concerns, and it must make economic sense for Canada under the net-benefit test. A net-benefit test kicks in when the transaction's enterprise value is at least $2.07-billion for a buyer from a country that has a trade deal with Canada. After approving Switzerland-based Glencore PLC's acquisition of a majority stake in Teck's coal business in 2024, then-industry minister François-Philippe Champagne said Canada would only approve foreign acquisitions of important Canadian mining companies engaged in significant critical-minerals operations "in the most exceptional of circumstances."
