TORONTO, Oct 12 (Reuters) - Canada's main stock index headed lower for the fourth straight day on Wednesday as lower oil prices weighed on energy stocks, offsetting gains for gold miners.
The Toronto Stock Exchange's S&P/TSX composite index .GSPTSE was down 16.10 points, or 0.11 percent, at 14,533.50, shortly after the open. Five of the index's 10 main groups were lower.
