Hintz made it 3-1 at 4:04 of the third period. He got behind Vancouver's defense, held off a backcheck from Noah Juulsen, and slid a backhand five-hole on Demko.
Hintz then scored short-handed into an empty net at 16:33 to push it to 4-1.
“I think the third period was solid. I think it was the best that we had, but we can play a lot better than that game,” Stars defenseman Esa Lindell said. “Jake gave us a chance and special teams were a big part today.”
DeBrusk cut it to 4-2 at 17:51, stuffing the puck in from the top of the crease for a power-play goal, but Robertson scored his second of the game into an empty net with 53 seconds remaining to make it 5-2.
Soucy scored on a one-timer from the right circle with four seconds left for the 5-3 final.
“I thought the guys played a really strong game tonight. I thought we did a lot of good things. We’ll look at ways to always get better,” Canucks defenseman Tyler Myers said. “Guys played hard tonight. It was a close game. A couple of empty-netters at the end made it look, the score didn’t really match how the game was.”
