I've never skied there, but I went mountain biking in the Chic Chocs a few years ago. It's something like six hours from Montreal and more than three from Quebec City. Plus, the region, while really beautiful, isn't exactly hopping economically (really high unemployment rates), so I don't know where the skiers would come from.
Ski areas in far more populated areas of Quebec (Orford, Mont Glen, Crapaudiere, Montjoye) have closed or are threatening to shut down, so even though the Chic Chocs is a different kettle of fish compared to most other EC mountains, I don't see how it could survive.
