Toronto stock index slides on resources, BCE rises

TORONTO, July 4 (Reuters) - The Toronto Stock Exchange's main index retreated in thin volumes on Friday as softer commodity prices pulled down energy and materials issues, while telecoms giant BCE (BCE.TO) provided an upward push.

The S&P/TSX composite index .GSPTSE fell 127.54 points, or 0.9 percent, to unofficially close at 14,016.03.
