Filip Chytil scored twice as Vancouver topped Calgary 5-1 to open the season, sparking a four-goal third period. Demko came up with key late-second stops, and Vancouver benefitted from depth with Sherwood, Lekkerimäki and Boeser contributing. Calgary avoided a shutout thanks to Morgan Frost, but injuries sidelined Bahl and Zary. Up next: Vancouver visits Edmonton; Calgary hosts St. Louis.
