Aug 23 (Reuters) - Canada’s commodities-heavy stock index inched toward record highs on Monday as oil prices rebounded from a seven-day losing streak, although gains were capped by concerns around slowing global economic growth. At 9:30 a.m. ET (1330 GMT), the Toronto Stock Exchange’s S&P/TSX composite index was up 72.97 points, or 0.36%, at 20,411.99, with the energy sector jumping 2.6%.
