TORONTO, June 4 (Reuters) - Canada's main stock index opened lower on Wednesday as investors were disappointed by sluggish U.S. private sector job growth and as a drop in the price of copper dragged on the mining sector. The Toronto Stock Exchange's S&P/TSX composite index was down 29.45 points, or 0.20 percent, at 14,705.24 shortly after the open. (Reporting by John Tilak; Editing by Bernadette Baum)
