TORONTO, Jan 27 (Reuters) - Canada's main stock index slipped on Friday as some heavyweight natural resource stocks weighed, while electronics manufacturer Celestica Inc jumped to a 12-year high.
Celestica surged 9.6 percent to C$18.30 after its adjusted earnings beat expectations and it said it would exit the oversupplied solar panel manufacturing market.
The energy group retreated 0.6 percent as oil prices slipped on an increased focus on U.S. production increases that could lessen the impact of an OPEC agreement to reduce supply.

The index was heading for a 0.6 percent gain on the week and is within striking distance of an all-time high hit in 2014.
Rogers Communications extended a rally to its highest level since August as investors cheered Thursday's results that suggested its turnaround was on track. It advanced 1.6 percent to C$56.91.

The financials group remain unchanged.

The materials group, which includes precious and base metals miners and fertilizer companies, lost 0.2 percent.
Potash Corp and Agrium Inc both fell 1.1 percent. The companies, which plan to merge by mid-2017 to cut costs, are struggling with the deepest slump in a decade for the oversupplied potash fertilizer market.
