UPDATE 2-Toronto stocks tumble as resource shares drag
*TSX falls for second session as resources slide

TORONTO, Sept 3 (Reuters) - The Toronto Stock Exchange's main index slumped for a second day in a row on Wednesday, as concerns about falling demand for commodities dragged down resource shares.
Gains in the financial sector -- the only group to end higher -- pulled the index back from session lows as investors moved money out of the commodity-related companies and into banks. Among the gainers, Bank of Montreal BMO.TO rose 2.7 percent.
The index fell more than 1 percent, extending a 3 percent slide on Tuesday, as the materials and energy sectors fell along with oil and gold prices, as worries over softening demand took hold and the U.S. dollar strengthened.
In the oil patch, Canadian Natural Resources CNQ.TO was down 3.3 percent at C$81.98, while among gold producers, Barrick Gold ABX.TO fell 5.4 percent to C$33.12.
The S&P/TSX composite index .GSPTSE closed down 161.82 points, or 1.22 percent, at 13,137.72 with all but one of its 10 main sectors in negative territory. It had earlier hit a low of 12,959.86.
The materials sector led declines, giving up 3.9 percent as they were hurt by losses in the gold producers subindex. Fertilizer company Potash Corp of Saskatchewan POT.TO also dragged, falling 4.7 percent to C$164.53. Continued...
