TORONTO, Jan 15 (Reuters) - Toronto's main stock index fell on Friday morning, pressured by limp oil and gold prices that hit big commodity issues such as Barrick Gold (ABX.TO).
Barrick dropped 1.7 percent to C$40.68, while fellow miner Goldcorp (G.TO) was down 1.9 percent at C$40.74. Fertilizer producer Agrium (AGU.TO) sank 3.4 percent to C$64.63, while oil company Suncor Energy (SU.TO) dropped 0.8 percent to C$37.22.
The price of oil fell below $79 a barrel in part on the lingering effects of disappointing U.S. economic data released in the previous session, while gold prices also fell. [O/R] [GOL/]
"The commodities are a little weak so that's certainly helping send Toronto down," said Bruce Latimer, trader at Dundee Securities.
At 9:52 a.m. (1452 GMT), the Toronto Stock Exchange's S&P/TSX composite index .GSPTSE was down 79.56 points, or 0.67 percent, at 11,724.82.
Heavyweight names on the upside included Potash Corp of Saskatchewan (POT.TO), which rose 0.3 percent to C$118.51 after a brokerage upgrade.
