CANADA STOCKS-TSX slips, heads for weekly loss after four gains

TORONTO, July 29 (Reuters) - Canada's main stock index slipped in early trade on Friday, heading for its first weekly decline since mid-June, as economic data and energy earnings highlighted the damage done by a massive wildfire that hit oil sands production starting in May.

The Toronto Stock Exchange's S&P/TSX composite index was down 11.48 points, or 0.08 percent, at 14,541.24 shortly after the open. Six of its 10 sectors were lower, including energy down 0.6 percent.
