The Flames finished second in the Northwest Division, and qualified for the 2009 Stanley Cup Playoffs as the fifth seed in the Western Conference, their fifth consecutive appearance in the post season.
The Flames signed forward Todd Bertuzzi during the off-season, a move that generated controversy amongst a fan base with which he had been previously unpopular.
[1] Goaltender Miikka Kiprusoff became the focus of the team's early struggles, as his play was argued to be a major cause of the Flames' inability to hold a lead.
[4] The cancellation appeared to be a turning point in the season, as the Flames recorded a mark of 15–4–3 following the loss, including a dominating 5–2 victory over the Sharks at home.
The son of general manager Darryl Sutter, Brett scored a goal in his first game to help the Flames enter the Christmas break with a one-point lead on the Vancouver Canucks in the Northwest Division.
[7] Calgary expanded on that lead to five points after both Jarome Iginla and Mike Cammalleri posted career-high five-point nights in a 6–4 win over the Edmonton Oilers on New Year's Eve.
[13] Looking to improve the team, Sutter completed two significant deals at the March 4 trade deadline, acquiring defenceman Jordan Leopold from the Colorado Avalanche and centre Olli Jokinen from the Phoenix Coyotes.
[14] The deals paid immediate dividends, as Jokinen scored twice and Leopold once in a 5–1 victory the next night against the Philadelphia Flyers allowing the Northwest Division leading Flames to move ten points ahead of the second place Canucks.
[16] Calgary's lead fell to one point following consecutive shutout losses to the Pittsburgh Penguins and Columbus Blue Jackets in late March.
[17] The Flames and Canucks ended the season in a battle for top spot, as both teams repeatedly took over the division lead heading into the final week of play.
[18] Injuries continued to batter the Flames towards the end of the regular season, as defencemen Robyn Regehr (MCL) and Cory Sarich (broken foot) were both lost in early April.
[19] The injuries led the Flames to call up rookies Matt Pelech and John Negrin, the latter of whom had just finished his junior season and had never played a professional game, to make their NHL debuts against the Minnesota Wild.
[20] The Flames were forced to play their final games of the regular season with as few as 15 skaters, below the normal 18, as the team lacked available salary cap space to call up replacements without sending other players down to their minor league affiliate in Quad City.
[28] The first three games of the series were physically intense and occasionally violent, prompting the league to warn both teams to tone down both the verbal attacks they were exchanging as well as to remain within the rules when engaging in scrums after the play ended.
[38] 2007 first round pick Mikael Backlund played one game with the Flames after leaving his Swedish team before being sent to the Kelowna Rockets of the Western Hockey League.
[39] The Flames made two trades at the 2008 NHL Entry Draft, sending forward Alex Tanguay to Montreal and acquiring Mike Cammalleri from Los Angeles in two separate deals.
[62] Bertuzzi, who had previously been booed by Calgary fans every time he touched the puck was greeted with loud cheers when he was introduced before the Flames' first exhibition game of the season.
[14] The Flames then ended the day with a minor move, sending minor-league goaltender Kevin Lalande to Columbus for a fourth round pick.
[75] In the Kelly Cup playoffs, the Wranlgers defeated the Bakersfield Condors and Stockton Thunder in seven games each to reach the National Conference finals.
[78] As part of their affiliation agreement with Las Vegas, the Flames assigned four players to the Wranglers to begin the season: Gord Baldwin, Hugo Carpentier, Kevin Lalande and Dan Spang.
