Steven Lorentz redirected a shot by Brady Skjei near the goal line to push the lead to 4-1 at 4:09 of the third period.
The Canucks were 0-for-5 on the power play with five shots.
"It's hard when your power play is struggling and you come in and play against a team that's got the best penalty kill in the league," Boudreau said. "The more they kill, the stronger they get. Power plays go in fits and starts a bit, but on this [road] trip, it's let us down a bit."
