Moore, 29, has 8 goals and 9 assists for 17 points in 48 games for Florida. He signed with the Panthers as a free agent just before the start of the season.
The Canadiens will be Moore's seventh NHL team, and this marks the third year in a row that he's has changed teams in midseason. He was claimed off waivers from Minnesota by Toronto in 2007-08, and was traded from Toronto to Buffalo at last season's trade deadline.
Moore was originally drafted by the New York Rangers in the third round in 2000.
It's pretty crazy, but believe me when I say we didn't draft these players with the mindset we had to because they had good hockey-playing dads. It just turned out that way. But we're certainly glad they're a part of our organization.
