Okay, you've used two really odd examples so far... financial sector workers in Toronto, as if the rest of the country doesn't employ the same people, and now small businesses in Sudbury......... as if entrepreneurs can't / don't move to greener pastures. Government of Canada employees can transfer pretty easy, and generally get paid better than their private sector counterparts.
Aerospace employees? Steel workers? Which ones, specifically? You don't think they don't have transferable skills that will allow them to excel in other industries? The vast majority do, I suspect.
