CANADA STOCKS-TSX opens lower as Middle East tensions weigh

TORONTO, Sept 23 (Reuters) - Canada's main stock index
opened lower on Tuesday, slipping for a third straight session,
as military activity in the Middle East fueled a rise in market
volatility and weighed on shares of most major sectors.
    The Toronto Stock Exchange's S&P/TSX composite index
 was down 22.72 points, or 0.15 percent, at 15,106.28
shortly after the open.
