TORONTO (Reuters) - The Toronto Stock Exchange's main index opened slightly higher on Monday, despite weakness in energy and materials issues amid a retreat in oil and gold prices following a holiday-shortened week on both sides of the border.
Shortly after the opening bell, the S&P/TSX composite index .GSPTSE was up 2.87 points, or 0.02 percent, at 14,013.26. Of its 10 main sectors, five sectors were lower.
The key energy sector slipped 0.4 percent, following the price of crude oil which eased to around $142 a barrel as investors kept tabs on a firm U.S. dollar and tensions over Iran.
Materials fell 0.3 percent as the price of gold dipped.
