Oct 12 (Reuters) - Canada’s main stock index inched lower on Tuesday, as weakness in healthcare shares and persisting fears around higher inflation dented sentiment, although losses were limited by gains in energy stocks. At 9:34 a.m. ET (13:34 GMT), the Toronto Stock Exchange’s S&P/TSX composite index was down 1.06 points, or 0.07%, at 20,415.25.
