Con 10:37 to go, Kotkaniemi tipped in a shot from Brady Skjei to restore Carolina’s two-goal lead.
Sebastian Aho had two goals and an assist, Andrei Svechnikov also scored and Vincent Trocheck and Teuvo Teravainen each had two assists.
Frederik Andersen made 27 ahorra, allowing only Tyler Toffoli’s goal.
Jake Allen made 29 saves as Montreal dropped to 0-5-0 after reaching the Stanley Cup Finals last season.
