"Those things are what character teams are made of," forward Corey Perry said after slipping a shot under goalie Eddie Lack with 1.3 seconds remaining in overtime to give the Ducks a 4-3 victory.
Overtime happened only because center Nick Bonino blasted a tying shot off a sprawled Canucks defenseman past Lack with 87 seconds remaining in regulation.
"Our will and our character in the last two periods, never say die, was really tremendous," Coach Bruce Boudreau said. "If you believe you can win, you're always in the game."
Only five NHL teams in the last 40 years have recorded a point in their first 19 home games.
Falling behind, playing a lackadaisical first period "are things you learn from, you can't do that against good teams," Perry said. "But we never backed down, we kept grinding.
"We weren't ready to play, but something triggered us … to keep doing the things we've been doing. We're going to keep coming at you."
The Ducks out-shot Vancouver by a 20-2 margin in the second period, getting goals from Saku Koivu and Matt Beleskey, but then defenseman Kevin Bieksa launched a blue-line shot 66 seconds into the third period that beat Ducks goalie Jonas Hiller.
"It was [getting late], but we knew if we kept doing those things we were doing after the [first] break, we couldn't be denied," Perry said. "You're going to get those breaks, those chances. We created those. That's what good teams do."
Bonino's tying shot, set up by a Daniel Winnik pass, was the Ducks' 43rd of 49 total shots compared to Vancouver's 20.
"Probably the hardest shot I've taken in awhile," Bonino said of his 12th goal.
In overtime, Bonino drew Bieksa into a hooking penalty by getting past him with 1:06 left, matching members of the Canucks' NHL-best penalty-killing unit against the Ducks' 26th-ranked power-play group.
As the final seconds dwindled, Boudreau said he began to craft his shootout lineup. But center Ryan Getzlaf had the puck and heard Perry yell for it.
Perry, now with a team-best 23 goals, hadn't scored in seven games and was denied by Lack on five previous shots.
"Sometimes, you get in that mindset as a goalie, you feel you can stop anything, and he pretty much did," Boudreau said of Lack.
Perry said his winning shot "wasn't hard, that's for sure. I saw a couple seconds on the clock … and knew I had to shoot right away. It probably fooled [Lack] and found a way to go in. Of all the places I shot, a trickler was the one that went in."
The puck went between Lack's legs.
After giving up two power-play goals in the first period, Hiller has won 11 starts in a row, the first NHL goalie to do so since Phoenix's Mike Smith in 2012.
