DeBrusk scored his first goal as a member of the Canucks at 15:38 of the third period to give Vancouver a 2-1 lead. The forward took a pass from Quinn Hughes on the wing and beat Blackwood over his glove.
DeBrusk signed a seven-year, $38.5 million contract ($5.5 million average annual value) with the Canucks on July 1.
"It felt great. Obviously, it's been hard not to fixate on it,” DeBrusk said. “It's hard not to focus on it. It's one of those things where there are so many different things and new things that come with being on a new team. I'm getting a little more comfortable, but the same point every game that goes by, you just kind of feel it more."
Granlund tied it 2-2 with 1:17 left with Blackwood pulled for an extra skater with a shot from the wing over Lankinen's glove.
"When we put pucks where we can get them for the forecheck, we have a good forecheck," Warsofsky said. "We sustain O-zone pressure, but when we get pucks to the goaltender, and we don't put pucks where they need to so we can forecheck, that is where we get into trouble, and for whatever reason, we can't figure that out yet."
