I would say not. NAV CANADA, the agency responsible for providing air traffic control services in Canada, monitors flight corridors on an ongoing basis. NAV CANADA has the power to introduce, increase, reduce or stop air services, to change flight corridors, and to close or relocate the associated facilities.
In instances of non-compliance with the use of the air space, NAV CANADA takes the necessary steps and informs Transport Canada, which is responsible for the implementation of the transport act. Since safety and security are Transport Canada's priorities and raison d'être, you can rest assured that there is zero tolerance for any situation that could lead to an unacceptable increase in the risk to either flight safety or public safety.
