What makes you say that Burnaby is a deadzone? Metrotown, Brentwood, Lougheed all seem to be growing like crazy. I moved to Toronto a few years ago and I'm find myself surprised by new buildings every time I go back.
Lougheed is fair, I would generally consider that part of the Burquitlam span. It's awkwardly spread out with the mall itself sitting in a sea of parking lots, that doesn't tend to help build a good neighborhood but it is thriving, possibly due to being within short reach of the box stores out United/Woolridge.
Sorry, I was incorrect about Metrotown, it is a pretty nice city center but the rest of Burnaby suffers from west-coast suburb development, areas are either residential, res+light commerce or res+employers, it's hard to find a neighborhood where you can live, work and shop unless you're working in retail, and IMO a neighborhood that can't supply all three is going to fade away to pure residential in time due to NIMBYism.
