I have a friend who's a huge Springsteen fan and he tells me this artist:
http://www.ticketmaster.ca/event/100045049965A095?artistid=859195&majorcatid=10001&minorcatid=60
has Springsteen connections. As Bruce will be in town for TIFF, there's a chance he may show up at this gig to jam. (They've played together previously.) No guarantees...but may be worth a shot.
