TORONTO, Sept 21 (Reuters) - Toronto's main stock market index dropped on Monday morning, pulled down by lower oil and metals prices and reluctance to buy following a recent rally.
Big names on the downside included fertilizer producer Potash Corp of Saskatchewan Inc (POT.TO), down 2.4 percent at C$99.40, gold miner Barrick Gold (ABX.TO), down 1.5 percent at C$39.06, and oil company Suncor Energy (SU.TO), which fell 1 percent to C$38.19.

"The market has had a real nice run the last few weeks. You've got a little pullback here. It's pretty well across the board," said Bruce Latimer, trader at Dundee Securities.
At 10:22 a.m. (1422 GMT), the S&P/TSX composite index .GSPTSE was down 94.66 points, or 0.83 percent, at 11,351.29, with seven of its 10 main groups lower. The mining and fertilizer-heavy materials sector fell 1.5 percent, while oil and gas shares were off 1.2 percent.
The index is up about 4 percent this month, typically a time when investors expect weakness, Latimer said.
"All in all it's been a pretty good September. We're not out of the woods yet but it hasn't been a traditional September," he said.
The index is up about 50 percent from lows hit in early March.
The information technology group, up 1.4 percent, was the leading sector in the black on Monday morning, helped higher by BlackBerry-maker Research In Motion RIM.TO, up 2 percent at C$91.02. Health care shares rose 0.9 percent and consumer staples edged up 0.1 percent.
