Heavy Canadian oil weakened after Enbridge Inc. shut a Wisconsin pipeline that helps move Alberta crude to U.S. refiners.
The Calgary-based pipeline operator shut Line 14, which runs from Superior, Wisconsin to the Griffith-Hartsdale area in Indiana, after a July 27 leak. The 317,600-barrel-a-day pipe spilled an estimated 1,200 barrels of oil.
A new section of the line was tentatively scheduled to be installed today, Graham White, an Enbridge spokesman based in Calgary, said in an e-mail.

Syncrude added 25 cents to a discount of $3 versus the U.S. benchmark. Syncrude is a synthetic oil upgraded from tar-like bitumen in Alberta into refinery-ready crude.
