Jan. 10 (Bloomberg) -- Canadian crude oil weakened after Enbridge Inc. issued a mid-month apportionment notice for its Mainline pipeline system.
Enbridge Line 6a has been apportioned by 16 percent and Lines 4 and 67 each by 10 percent for the remainder of January, the company said.
Western Canada Select, a heavy bitumen blend, fell $2.50 to a $39.50 discount to U.S. oil benchmark West Texas Intermediate, according to Calgary oil broker Net Energy Inc. Syncrude, a synthetic light oil processed from oil-sands bitumen, fell 75 cents to a 25 cent discount, according to Net Energy data.
The mid-month shift was caused by power outages in Manitoba, as well as an electrical equipment failure in Edmonton in December, according to one of the people.

Company officials said Nov. 7 maintenance would begin this month, and the company reported extra emissions from the plant on Jan. 7. The refinery processes crudes from West Texas and Cushing.
