The third season of Battle of the Blades premiered on September 18, 2011, as a part of CBC's fall line-up. Like previous seasons, this season showcases a lineup of 8 couples.

Ron MacLean and Kurt Browning return as the show's hosts, with the addition of Virgin Radio 999 DJ Maura Grierson as the "Battle Correspondent", providing viewers a look backstage during the competition. Sandra Bezic continues as the head judge, with Jeremy Roenick as the other regular judge. This season will continue to have one rotating guest judge every week. The show venue for this season is MasterCard Centre in Toronto, Ontario.^[1]

Like the previous season, the September 18th-season premiere was actually a preview of the competition, entitled "Battle of the Blades: Game On". It documented the announcement of the cast, training camp and partner assignments of the eight couples, and was dedicated to deceased competitor Wade Belak.^[2] The first competition night was broadcast live on Sunday, September 25, 2011. Due to public demand, there was no elimination in week 1, with the first couple eliminated in week 2.

This season introduces "The Judges' Save", which can be used to save a couple from elimination should they be voted off after the Monday night Skate-Off. However, it can only be used once during the entire season and only with the consensus of all judges.

The official cast announcement was made on the morning of August 22, 2011 on the show's website. It was revealed that the first female hockey player competitor would be cast this season: Olympic Women's Hockey gold medalist Tessa Bonhomme. She is partnered with Olympic Pairs Figure Skating gold medalist David Pelletier. The announcement also revealed six of the seven remaining male NHL hockey players and the all skating professionals. The seven female professionals this season include previous participants Marie-France Dubreuil (season 1 second runner-up), Anabelle Langlois (season 2), Violetta Afanasieva (season 2), and first-timers Elena Berezhnaya, Tanith Belbin, Kim Navarro, and Marcy Hinzmann-Harris. The partnering of competitors beyond Bonhomme & Pelletier were not announced at the time.^[3]

On August 30, 2011, former Calgary Flames team captain Todd Simpson confirmed on his Twitter page that he is the eighth hockey player participant of the season.^[4]

On August 31, 2011, competitor Wade Belak died less than one month before the scheduled premiere.^[5] CBC stated that Belak's death would not affect the show's premiere but did not announce at that time if Belak's spot would be replaced by another hockey player.^[6] CBC announced the season would open with a dedication to Belak, with footage of his final days training for the competition shown during the preview show, "Game On".^[2]

At the end of the programme "Game On", it was announced that Kim Navarro, originally Wade Belak's partner, would now be skating with former participant Russ Courtnall. Courtnall participated in season 2 with Christine Hough-Sweeney and was the first couple eliminated. Courtnall and Navarro are competing for Belak's original charity of choice, Tourette Syndrome and Neurodevelopmental Clinic at the Toronto Western Hospital.^[7] Courtnall is the first hockey player participant to compete in more than one season.
