Pius Suter and Hughes scored, and Andrei Kuzmenko had two assists for the Canucks (32-11-4), who are 8-0-1 in their past nine.
“I thought [Demko] was solid as [heck]. We got the two-goal lead and a little prevent defense and won 2-0,” Vancouver coach Rick Tocchet said. “Obviously when you get a shutout, it’s always a team thing, but obviously, he’s a huge part of it.
"I love shutouts. I’d rather win 2-0 than 8-4 any day of the week. It gets you in the game, it means you’re doing the right things when you get a shutout.”
Petr Mrazek made 27 saves for the Blackhawks (14-31-2), who have lost five of seven and 17 straight on the road dating to Nov. 9 (0-16-1).
“Let's be honest, our record on the road isn't great, and I think sometimes we're wading into games on the road,” said Chicago forward Nick Foligno, who returned after missing seven games with a broken finger sustained Jan. 5. “Maybe I have a little bit better perspective watching a few games, and our tenacity and our compete and our readiness at home, it doesn't seem to be [there on the road]. It's almost like we're waiting to see what they're going to do before we respond and tonight, we get caught in that.”
