Draisaitl made it 2-0 at 18:20 of the second on a one-timer from the bottom of the left face-off circle that went over the outstretched pad of Demko.
"This power play, every time they're out there wants to score and thinks that they can score," Hyman said. "We don't really think about the numbers or the percentages, it's just let's go get a goal."
McDavid assisted on the goal, extending his point streak to seven games to start the season. Demko stopped McDavid twice on breakaways in the third period, leaving the Oilers captain one game short of tying the Edmonton record for multipoint games to start a season (Wayne Gretzky, 1983-84).
"He's going to get his chances no matter what, but you hold him to a power-play point and two power-play goals at the end of the day against them, it is a good job at 5-on-5," Canucks forward Bo Horvat said. "But we've got to find a way to win those hockey games. When you do hold a team like Edmonton to two goals, you've got to figure out a way to score three."
Koskinen, making his fourth straight start with No. 1 goalie Mike Smith injured, made his best saves on a late Canucks power play with Demko pulled for an extra attacker, robbing Oliver Ekman-Larsson and Boeser before Boeser ended his shutout bid with a high blocker shot from inside the left face-off dot.
"'Koskie' really made some big saves there late, so it's tough to see him lose a shutout. But that being said, it's a good two points," Oilers coach Dave Tippett said.
Boeser hopes it can be a springboard for a Canucks team struggling to score.
"Hopefully just getting that last one, the floodgates will open up," Boeser said.
NOTES: Smith (lower body) traveled with the Oilers and participated in the morning skate Saturday. He remains day to day, according to Tippett, but could return Monday at home against the Seattle Kraken. … Canucks defenseman Tucker Poolman had two hits and three blocked shots after missing one game with an upper-body injury. … Vancouver center Jason Dickinson played 11:44 in his return after missing two games with an undisclosed injury. … Canucks defenseman Luke Schenn played 14:13 and had four hits and one blocked shot in his 800th NHL game.
