Oct 3 (Reuters) - Canada's main stock index was flat on Thursday, as gains in cannabis producers and miners offset early weakness following poor readings on U.S. services sector activity.
* At 11:14 a.m. ET (1514 GMT), the Toronto Stock Exchange's S&P/TSX composite index .GSPTSE was up 15.11 points, or 0.09%, at 16,326.08.
* The index had fallen about 0.5% earlier after the latest numbers from the United States, the world's largest economy, showed services sector growth slowed to its most anemic pace in three years last month. That added to a string of poor data from the euro zone on Thursday amid growing evidence that the world economy was taking a toll from the bruising U.S.-China trade war.
* Miners .GSPTTMT jumped, with shares in Torex Gold Resources TXG.TO , Yamana Gold Inc YRI.TO and Barrick Gold ABX.TO rising between 3% and 5%, as the safe-haven appeal of the metal got a boost in the wake of the data.
* Weed companies were among the top gainers, with shares in Aurora Cannabis ACB.TO jumping 4% after the company provided positive updates on global operations. Shares of Aphria Inc APHA.TO and Canpoy Growth WEED.TO gained about 2%.
* The top decliner in Canada's main index was manufacturing firm Linamar Corp LNR.TO , which slumped 12.4% after warning of the negative impact on its earnings from trade uncertainties and an autoworkers' strike at General Motors (NYSE:GM) GM.N .
* A slide in oil price below $57 a barrel due to signs of excess supply and global growth worries drove the energy index .SPTTEN down 0.8%. O/R

* The TSX posted two new 52-week highs and nine new lows.
