Just to clarify the story, the feds stopped funding airports years ago, so that is not the problem for YKZ. The GTAA is the agency that has cut off their subsidy to YKZ as an "overflow" airport for YYZ. They are facing a major budget shortfall for the next few years due to a drop in airline and passenger traffic, and are under pressure from the airlines to keep their already high fees in check. Hence the reason they are cutting off the annual cheque to YKZ.
