May 3 (Reuters) - Canada's main stock index was subdued at the open on Wednesday, as a drop in crude prices dragged energy shares down, while investors remained cautious before the U.S. Federal Reserve's policy meeting outcome.
At 9:31 a.m. ET (1331 GMT), the Toronto Stock Exchange's S&P/TSX composite index (.GSPTSE) was down 3.38 points, or 0.02%, at 20,404.18.
