Bennett, 18, will join the Flames prior to their road game against the Edmonton Oilers on Saturday (10 p.m. ET; CBC).
"It's pretty surreal right now," Bennett told the Flames website. "I’m sure when I’m out there and around the team, it will feel a lot more real. Obviously I’m really excited to be out there with them. It's a really exciting time of the year, especially for Calgary right now. I can't wait.
"This is what I have wanted since I was 4 years old. I’m really excited to get going and meet the team."
