The biggest proposed leveraged buyout in Canadian history has finally come to an end, with telecom giant BCE failing to met the solvency requirements. The collapsed deal, plus problems with a bailout of the auto sector in the United States, put a damper on the big board stocks during Thursday trading on the Canadian markets. For the tale of the tape, the TSX Exchange slumped 2.8%, while the TSX Gold Index gave back 3.4% and the TSX Venture Exchange, Canada’s largest junior exploration bourse, added 1.12% with the advancing issuers beating out the decliners by a 424 to 416 margin on volume of 238 million shares traded.
