Jonathan Lekkerimaki put the Canucks ahead 3-2 just 1:10 into the third period. Following a giveaway by Oilers forward Isaac Howard, Lekkerimaki skated into the top of the right circle and put a wrist shot between Jarry’s pads.
Sasson pushed the lead to 4-2 at 2:55, working a give-and-go with Drew O'Connor before tucking a backhand five-hole on Jarry.
Elias Pettersson made it 5-2 at 5:15, redirecting a shot-pass from Hronek for a power-play goal.
“I always try to give (Hronek) a blade to shoot at, and he shot,” Pettersson said. “The puck goes in the net and they didn’t have time to react to it. He made that play. It was all him.”
Podkolzin closed the gap to 5-3 at 8:56, settling a centering pass from Bouchard at the edge of the crease and jamming the puck into the net.
Bouchard then completed the hat trick 24 seconds later to make it 5-4.
Podkolzin scored his second of the period with 43 seconds left to tie it 5-5. With the Oilers on the power play and Jarry off for an extra attacker, Podkolzin took a cross-ice pass from Leon Draisaitl and ripped a wrist shot over Lankinen's glove from the left circle.
“You could tell it was our first regular-season game. We’ve got to be a lot more detailed than that,” Bouchard said. “Giving up odd-man rushes, giving up five, six, isn’t going to cut it.
“We had the puck, we were playing perimeter. You could see when we kept things simple and put it in and forechecked their 'D' then we had the slot open. We just didn’t do that enough.”
Cotter gave the Canucks a 1-0 lead with a short-handed goal at 9:51 of the first period.
Bouchard tied it 1-1 at 16:26 with a wrist shot from the point that made it through a screen from Zach Hyman.
Marco Rossi responded for Vancouver to make it 2-1 at 2:07 of the second period. He got behind the defense, took a lead pass from Liam Ohgren, and beat Jarry blocker side on a breakaway.
Bouchard tied the game 2-2 at 14:34. McDavid picked up the puck from a fallen Alex Formenton and sent a backhand pass into the low slot, where Bouchard scored glove side on Lankinen.
“There were a lot of momentum swings, energy swings on the bench," Malhotra said. "Just the overall pace of the game, I was trying to make sure I was keeping an eye on who was on the ice when they were on the ice. There was a lot of moving parts, but it was definitely a fun one to coach.”
NOTES: Malhotra is the fourth person to represent the Canucks as both a player and head coach, joining Marc Crawford, Pat Quinn and Orland Kurtenbach. ... Cotter became the first player to score a short-handed goal in his Canucks debut. ... Bouchard became the third defenseman in NHL history to score a hat trick in a season opener, joining Mark Howe (Oct. 9, 1980) and Bert Cobeau (Dec. 25, 1919).
