TORONTO, Dec 6 (Reuters) - Canada's main stock index wavered on either side of flat in early trade on Tuesday, as slipping energy stocks were offset by a jump in Bank of Montreal BMO.TO shares after its earnings beat expectations and a surge in Kirkland Lake Gold Inc KLG.TO after it completed a merger.
The Toronto Stock Exchange's S&P/TSX composite index .GSPTSE was up 20.66 points, or 0.14 percent, at 15,115.83 shortly after the open. Seven of its 10 main groups were lower.
