CANADA STOCKS-TSX opens little changed as resource shares weigh

TORONTO, Aug 27 (Reuters) - Canada's main stock index was little changed at the open on Wednesday as weakness in energy and materials shares offset a gain in the financial sector. The Toronto Stock Exchange's S&P/TSX composite index was down 11.99 points, or 0.08 percent, at 15,607.22 shortly after the open. (Reporting by John Tilak; Editing by Jeffrey Benkoe)
