TORONTO, Jan 9 (Reuters) - Canada's main stock index fell in morning trading on Monday, led by a retreat among energy stocks as oil prices lost ground, while financial, consumer, telecom and industrial stocks also weighed.
At 10:31 a.m. EST (1531 GMT), the Toronto Stock Exchange's S&P/TSX composite index .GSPTSE was down 106.7 points, or 0.69 percent, at 15,389.35. There were two decliners for every gainer.
Among the most influential movers on the index were some of its biggest oil and gas producers and major financial stocks.
The energy group retreated 2 percent, while financials slipped 0.7 percent.
Suncor Energy Inc SU.TO lost 1.3 percent to C$43.52, and Canadian Natural Resources Ltd CNQ.TO fell 2.4 percent to C$42.12 as oil prices fell more than 2 percent.
Signs of growing U.S. production outweighed optimism that many other oil producers, including Russia, were sticking to a deal to cut supplies to bolster the market. O/R
