TORONTO - The Toronto stock market surged 200 points Wednesday thanks to substantial runups in energy and base metals stocks, but gains would have been much higher if not for a big drop in BCE Inc. (TSX:BCE) shares on word its buyout is in serious trouble.

Toronto's S&P/TSX composite index gained 200.66 points to 8,643.52.

BCE shares plunged $13.10 or 34 per cent to $25.25 on news that the Montreal-based company couldn't meet certain solvency tests in its agreement to be bought by an investor group led by the Ontario Teachers' Pension Plan.

"I think people are very surprised at this stage what has derailed it," said Julie Brough, vice-president private wealth management at Morgan, Meighen and Associates.

"I think there's a lot of people that would argue that it was a bad deal from day one, and that Teachers' was paying way too much and taking on too much debt. I think the deal is dead, personally."

The telecom sector gave back more than 10 per cent with Telus Corp. (TSX:T) down 76 cents to $38.09 and Rogers Communications (TSX:RCI.B) fell 86 cents to $34.34.

In the United States., markets posted strong gains for a fourth day after President-elect Barack Obama pledged to have a plan ready for action to deal with the country's financial crisis on his first day in office.

Obama announced that former Federal Reserve chairman Paul Volcker would head a new White House panel to help create jobs and bring stability to the ailing financial system.

On the TSX, the energy sector was ahead 7.66 per cent as the January crude oil contract gained $3.67 to US$54.44 per barrel on the New York Mercantile Exchange. A large interest rate cut in China and news of a possible Russian output cut countered a new government inventory report showing far more crude and gasoline in storage in the U.S. than was expected.
