The Habs were eliminated in Game 6 of their second-round playoff series against the Tampa Bay Lightning with a 4-1 loss.
While the game was played in Florida, it was broadcast on giant screens at the Bell Centre, where fans were hoping they would be able to see their heroes in person on Thursday in a winner-take-all Game 7.
Instead, many started pouring out with 10 minutes left and Tampa Bay holding a 3-0 lead.
There was a police presence around the downtown arena but nothing like that seen in some previous years when authorities feared widespread vandalism and violence.
Montreal has witnessed scenes of torched police cruisers and smashed shop windows in some years but the downtown core was calm Tuesday night.
Many fans had seen their hopes raised when Montreal rallied to 3-2 in the series after dropping the first three games.
The Habs were the last Canadian team to win the Stanley Cup, defeating the Los Angeles Kings in 1993.
