TORONTO, Oct 15 (Reuters) - Canada's main stock index
slipped at the open on Thursday, hurt by a retreat among
resource stocks on lower oil prices and a slump in Valeant
Pharmaceuticals International Inc VRX.TO after it was
subpoenaed by U.S. prosecutors over drug pricing.

.GSPTSE was down 22.32 points, or 0.16 percent, at 13,853.01.
Seven of its 10 main sectors gained, however, led by financial
and industrial stocks.
