Flames forward Johnny Gaudreau's NHL career-high point streak ended at 11 games. He had 22 points (10 goals, 12 assists) in that span.
Calgary has won 11 of its past 14 games (11-1-2) and is in first place in the Western Conference heading into 2019 Honda NHL All-Star Weekend, which will be followed by their mandatory five-day break.
"We're proud of what we've done up to this point, but we're not where we want to be yet," Jankowski said. "There's a lot of season left to go, and these next 30-something games are going to be a grind. We have to come back from the break ready to come right back right where we left off."
Dougie Hamilton scored, and Mrazek made 22 saves for the Hurricanes (23-20-6), who have lost three of the past four.
"I liked the way we played," forward Teuvo Teravainen said. "We didn't get the result, but if we keep playing like, that I'm pretty sure we can get some wins. I think they're a pretty good team. It's a really, really good game both ways."
