TORONTO, Feb 18 (Reuters) - Canada’s main stock index edged higher on Thursday, sustaining a six-week high, as consumer and telecom stocks made modest gains, while shares in energy companies pulled back despite a further rise in crude oil prices.
The most influential movers on the index included Canadian Tire Corp, which advanced 6.4 percent to C$123.97 after its earnings beat expectations despite a slip in revenue. .
The consumer groups were higher, with staples up 0.9 percent and discretionary gaining 0.4 percent, while telecom stocks added 0.8 percent.
The country’s largest wireless provider, Rogers Communications Inc, rose 1.1 percent to C$49.25.
The energy group retreated 0.7 percent, even as oil rose above $35 a barrel after Iran welcomed plans by Russia and Saudi Arabia to freeze output and an industry report showed a surprise drop in U.S. inventories.
Canadian Natural Resources declined 2.6 percent to C$29.02 and Enbridge Inc fell 1.4 percent to C$44.86.
