"dying" is hyperbole. The manufacturing sector has been on decline for 40 years but other sectors are starting to build up. The downtown core has seen a boom in revitalization, particularly these past 5 years. There's a push for tech and startups.
It's basically in the same metro area as Chicago. Would you say Chicago's dying? It may have declined (or not grown as fast as other US cities) lately but "dying" seems like hyperbole, no?
