** Says volatile crack spreads in U.S. midwest and Ontario to influence earnings for integrated oil companies
** Some of the positives will be offset by higher costs and lower production due to Alberta output cuts - CIBC
** Expects Suncor Energy Inc, Husky Energy Inc , Cenovus Energy Inc, MEG Energy Corp, Athabasca Oil Corp and Canadian Natural Resources Ltd to beat consensus estimates in Q1 (Reporting by Debroop Roy in Bengaluru)
