TORONTO, Feb 24 (Reuters) - Toronto's main stock index fell on Thursday for a fourth straight session as oil and gold shares retreated after rising for several days in reaction to the upheavals in North Africa.
The Toronto Stock Exchange's S&P/TSX composite index .GSPTSE unofficially closed down 88.88 points, or 0.64 percent, at 13,867.31. By the end of the day the index had given back all of the gains it made last week, when it closed above 14,000 for the first time since July 2008.
Five of the index's 10 main groups were lower, with the materials group leading the decline, falling 2.2 percent.
