CANADA STOCKS-TSX ends down as Scotiabank leads financials lower

TORONTO, Nov 28 (Reuters) - Canada's main stock index ended slightly lower on Tuesday, weighed by a fall in Bank of Nova Scotia shares after it agreed to buy a bank in Chile, with investors rattled after North Korea fired a ballistic missile.

The Toronto Stock Exchange's S&P/TSX composite index unofficially closed down 12.48 points, or 0.08 percent, at 16,029.64. Seven of its 10 main sectors ended lower. (Reporting by Alastair Sharp Editing by Marguerita Choy)
