TORONTO, May 24 (Reuters) - Canada's main stock index fell slightly in early trade on Wednesday, with Bank of Montreal shares off after the company's earnings missed estimates and investors awaiting a Bank of Canada interest rate decision and minutes from the last U.S Federal Reserve meeting.
The Toronto Stock Exchange's S&P/TSX composite index .GSPTSE was down 12.98 points, or 0.08 percent, at 15,463.96 shortly after the open. Its heavyweight financial group lost 0.6 percent.
