TORONTO, Oct 21 (Reuters) - Canada's main stock index
see-sawed in morning trade on Wednesday, helped by gains among
banks, railways and telecom stocks, while a fall in the price of
oil and other commodities pushed energy and mining shares lower.
The most influential gainers included telecom company BCE
Inc BCE.TO , which rose 0.9 percent to C$58.05, and Canadian
National Railway CNR.TO , which advanced 0.7 percent to
C$79.10.
The financials group climbed 0.5 percent, with
Toronto-Dominion Bank TD.TO rising 0.5 percent to C$53.43, and
Royal Bank of Canada RY.TO advanced 0.4 percent to C$74.71.
On the downside, the energy group retreated 1.0 percent and
materials, which includes miners, retreated 1.1 percent.
Prices for copper and iron ore are being pressured by weak
demand from China.
China's benchmark indexes slumped roughly 3 percent on
Wednesday in their worst daily performance in five weeks, while
oil prices fell after a big build in U.S. crude inventories
exacerbated a global supply-demand imbalance.
