Dube, like Valimaki, made Calgary's roster out of training camp last season. He played 20 of the Flames' first 25 games, averaging 10:16 of ice time, before continuing his season with Stockton to develop in a more prominent role.
The 21-year-old center, who was captain of Canada's 2018 IIHF World Junior Championship-winning team, averaged 1.05 points per game in the AHL last season, one of 13 players to average more than a point per game (minimum 30 games played).
Dube (5-11, 187), who has shown his offensive prowess in the AHL and Western Hockey League, is expected to compete for an NHL roster spot this season.
