TORONTO, June 16 (Reuters) - Toronto's main stock index was lower in choppy trading on Thursday morning as Greece's debt woes cast a pall on market sentiment.
Miner Goldcorp (G.TO) was off 1.03 percent at C$46.28 and was the most influential decliner.
At 10:49 a.m. (1449 GMT), the Toronto Stock Exchange's S&P/TSX composite index .GSPTSE was down 16.00 points, or 0.12 percent, at 12,956.03 after hitting its lowest level in more than six months, 12,885.54, earlier in the day. It hit 12,883.27 on November 30.
"The Canadian market is down somewhat, reflecting continuing gloom on major issues on a global basis, after having one pretty decent day two days ago," said Michael Smedley, chief executive of Morgan Meighen & Associates Ltd.
The index's materials group, home to miners, was down 0.58 percent, tracking lower with copper prices, which fell on a stronger U.S. dollar, fears of weak U.S. economic growth, and worries about what will happen if the Greek debt crisis stays unresolved.
Uncertainty over Greece kept safe-haven bullion steady, but prices were off Wednesday's highs, which weighed on gold-mining shares. [MET/L] [GOL/]
