A two-goal second period gave Chicago a 4-1 lead after 40 minutes, but the Flames came out hard in the third and made it a one-goal game.
The first goal came just 84 seconds in when Bourque lifted the puck over Crawford from the low right side and a one-timer from Iginla in the slot off a feed from Alex Tanguay made it a 4-3 game at the 8:44 mark.
Chicago, though, got some insurance just over two minutes later when a one- timer by Bolland from the right circle gave the team a 5-3 lead.
The Flames once again made it a one-goal game when Iginla’s slap shot from a sharp angle at the right side trickled though Crawford over to the left where Bourque slammed it home with 3:56 to play.
Calgary later got Karlsson out of the net for the extra attacker, but Hossa sealed the win with the empty-netter.
“We were not good defensively. We gave up over 20 scoring chances, and that’s not good enough,” Flames head coach Brent Sutter said.
Toews scored 6:46 into the game while Tanguay lit the lamp on the power play halfway through the first frame.
Frolik scored his first goal with Chicago and first in 32 games at the 18:25 mark of the first when he chipped it in as he crashed the net.
Campbell’s streaking one-timer from the top of the right circle gave Chicago a power-play goal and a 3-1 lead with 4:49 left in the second while Toews scored on a nice individual effort 1:22 later for a 4-1 lead.

The Blackhawks are hot right now, but they need to keep winning -- as most of the teams around them are doing. Their five-game winning streak has put them into a tie for sixth place in the Western Conference playoff standings, only two points out of fourth. But they also stand just five points ahead of the 12th place Columbus Blue Jackets.
Also, the Hawks have come very, very close to a long winning streak. Their last three losses are all by one goal and two of them came in shootouts. That bodes well for putting together a streak that might even get them back in contention to take the Central, although they're 10 points behind the Red Wings.
With Jonathan Toews carrying them and having some writers push his candidacy for league MVP, and with coach Joel Quenneville apparently having decided that Corey Crawford is the No. 1 goalie -- the right call, it would appear -- the Hawks might be able to put on a real run for the Cup again.
Tonight's game has an unusual starting time -- 8 p.m. CST -- and is on CSN Chicago.
