TORONTO, July 31 (Reuters) - Canada's main stock index edged higher on Monday as higher bond yields supported financial shares and its base metal miners got a boost from a 2-year peak for copper prices, but the TSX still lost ground for the third straight month.
The Toronto Stock Exchange's S&P/TSX composite index .GSPTSE unofficially closed up 15.22 points, or 0.1 percent, at 15,143.87. Just four of the index's 10 main groups ended higher.
