CANADA STOCKS-TSX turns negative as sliding oil prices drag energy shares

TORONTO, May 31 (Reuters) - Canada's main stock index turned negative shortly after the open on Wednesday, as a sharp decline in energy companies, hurt by falling oil prices, offset a broad rally in most other sectors.

The Toronto Stock Exchange's S&P/TSX composite index rose 9.71 points, or 0.06 percent, to 15,382.06 shortly after the open.

Three of the index's 10 key groups were in negative territory. (Reporting by Solarina Ho; Editing by Chizu Nomiyama)
