In October, Husky made an unsolicited formal offer to buy MEG Energy in a deal valued at C$6.4 billion, in an effort to integrate assets and offset the deep price discounts on Canadian crude.

MEG had rejected Husky's offer. The company could not be reached immediately for comment.

Husky's offer is open for MEG to accept until Jan. 16, 2019, the company said in a statement.
