[2017] F.C.J. No. 130

2017 FC 155

Federal Court

D. Gascon J.

Varadi, a civil pilot, had his transportation security clearance (TSC) revoked and canceled in 2015 after Transport Canada had become aware through a report by the RCMP that he had previously sent life-threatening emails to various organizations throughout 2007 to 2013. Varadi applied for judicial review of this decision, arguing it was unreasonable, that he had a legitimate expectation that Transport Canada would not cancel his TSC as it had been recently renewed in 2014, and that he did not receive procedural fairness as he was denied a fair opportunity to respond to the concerns.

The Court found the decision to revoke and cancel Varadi’s TSC was reasonable and that he was treated fairly given his entitlement to procedural fairness in this context (when an existing security clearance is being revoked) was on the lower end of the spectrum. Regarding Varadi’s claim about legitimate expectations, the Court noted that not only was Transport Canada not made aware of the emails until after it received the RCMP report in 2015, it would also be contrary to the aim of the TSC program, which is to ensure security while preventing unlawful acts of interference with civil aviation, to accept that events that took place before the last TSC renewal, but that were unknown at that time, should not be considered by Transport Canada. In the result, the Court dismissed Varadi’s application.
