Investigation and conviction

The investigation into Delisle was triggered by a tip from the U.S. Federal Bureau of Investigation on December 2, 2011. His home was searched that month and he was arrested the following January.

Delisle had previously been stopped by Canada Border Services Agency agents at Halifax airport in September 2011 after returning from a trip to Brazil to meet his GRU handler, carrying a large amount of cash and prepaid credit cards. There is no sign this led to an investigation. In May 2013, The Canadian Press reported that Canadian Security Intelligence Service had been aware of Delisle's spying well before the FBI tip, but failed to contact the Royal Canadian Mounted Police.

On February 13, 2013, it was announced by DND that Delisle had been stripped of his commission and service decorations and been dishonourably discharged. DND was also moving immediately to recover the salary paid to Delisle since his arrest in January 2012.

The Parole Board of Canada granted Delisle day parole in October 2018, and full parole in March 2019.
