TORONTO, June 7 (Reuters) - Canada's main stock index fell on Wednesday as a sharp drop in oil prices put pressure on energy shares, which slumped to an 11-month low, while investors weighed political uncertainty ahead of key events on Thursday.
The Toronto Stock Exchange's S&P/TSX composite index .GSPTSE unofficially closed down 92.42 points, or 0.6 percent, at 15,372.14. Eight of the index's 10 main groups ended lower.
