UPDATE 1-Bank shares roil Toronto stock market
TORONTO Jan 15 (Reuters) - Toronto's main stock market index dropped more than 200 points on Tuesday amid falling commodities shares and worries over the health of the North American banking shares and another writedown at Canadian Imperial Bank of Commerce CM.TO.
The Toronto Stock Exchange's S&P/TSX composite index .GSPTSE was down 227.63 points, or 1.7 percent, at 13,470.65.
All 10 of the TSX index's main groups were lower, led by a 2.5 percent drop in the influential energy group and a 1.8 percent fall in the heavily weighted financial group. The commodity heavy materials group was down 1.3 percent.
