Sorel lasted from 1969 to 1981, that's not exactly "soon after" the start of the league.
First Sorel franchise with Raymond Bourque left for Verdun after the 1976-77 season and was replaced. Two franchise failures in one city, only game in town, even though they had many stars and a winning record virtually all the time is not a good omen.
13 seasons after the start of a league that is 40 years old and counting is much closer to soon after then to well into.
No it wasn't. They moved to Verdun in 1977 but were back in 1979. Same franchise.
And the fact they didn't succeed thirty years ago is reason to keep them from having a second chance?
Effectively they had two chances according to your post. The Cardin is not getting any younger nor is it getting bigger. The economy is in the pits since the shipyards are virtually closed and local industry is marginal. Could not support the LNAH and lost the Midget AAA more than 10 years ago.
Granted Verdun has had numerous chances but the arena gets updated, a second rink was added, the area is gentrifying with some growth. Walking distance to a subway station with access to the Montreal market, media and population.
