TORONTO (Reuters) - Canada's main stock index fell for the first time in four sessions on Thursday as energy and mining stocks were hurt by declining prices and weak investor sentiment, while BlackBerry plunged on doubts about the company's recovery plan.
The Toronto Stock Exchange's S&P/TSX composite index fell 53.54 points, or 0.43 percent, to 12,481.37.
