By John Tilak TORONTO (Reuters) - Canada's main stock index slipped on Tuesday after a selloff in the oil price caused shares of energy producers to decline, offsetting gains in Bank of Montreal and BlackBerry . We've had a record run," said David Cockfield, managing director and portfolio manager at Northland Wealth Management. "But I don't think we're into a major selloff here." The Toronto Stock Exchange's S&P/TSX composite index was down 23.92 points, or 0.17 percent, at 14,203.16. Canadian Natural Resources Ltd shed 1.3 percent to C$40.51, and Encana Corp fell 1.9 percent to C$21.07.
