Sept 3 (Reuters) - Canadian equities inched higher on Friday as a jump in commodity prices lifted mining stocks, although gains on the main index were capped by a dismal U.S. jobs report that sparked fears of slowing global growth. * At 9:32 a.m. ET (13:32 GMT), the Toronto Stock Exchange’s S&P/TSX composite index was up 19.11 points, or 0.09%, at 20,814.23.
