The televised competition — which pairs hockey players with figure skaters — returns Sept. 22.
Hosted by CBC sports announcer Ron MacLean, the show aired for three seasons but took a break last year.
CBC says the cast will be revealed online starting Sunday.
The new season will see a change in format, with a combined hour of performance and elimination.
The show's co-creator, Sandra Bezic, previously served as head judge but will now act as executive producer and mentor to the skaters.
