The world, including Canada, is peppered with ghost or struggling communities that were founded resource sites - the so-called 'one industry town'. The day a mine shift is christened, its shut-down clock starts. A few, very few, like Sudbury and Timmins, are rich enough to be stable over a long-term. Expecting a durable, economically viable community based on a single mine is folly.
Admittedly, the rules regarding what constitutes and justifies a community in the high arctic are different, but the Inuit have fairly recent memory of being relocated for the greater good. Maybe Milne Point is a better location than Pond Inlet ~130km away. Dunno.
