CANADA STOCKS-TSX retreats as energy, financials weigh

TORONTO, May 31 (Reuters) - Canada's benchmark stock index finished lower on Wednesday as a slide in oil prices squeezed energy companies, while a quarterly report on the country's economy cast a cloud over financial shares.

The Toronto Stock Exchange's S&P/TSX composite index closed down 22.44 points, or 0.15 percent, at 15,349.91. Half of the index's 10 key industry sectors ended lower. (Reporting by Solarina Ho, editing by G Crosse)
