Oh, I can help you with that!

> Arar was detained during a layover at John F. Kennedy International Airport in September 2002 on his way home to Canada from a family vacation in Tunis.[1] He was held without charges in solitary confinement in the United States for nearly two weeks, questioned, and denied meaningful access to a lawyer.[1][2] The US government suspected him of being a member of Al Qaeda and deported him, not to Canada, his current home and the passport on which he was travelling, but to Syria.[3][4] He was detained in Syria for almost a year, during which time he was tortured by Syrian authorities, according to the findings of a commission of inquiry ordered by the Canadian government, until his release to Canada. The Syrian government later stated that Arar was "completely innocent."[5][6] A Canadian commission publicly cleared Arar of any links to terrorism, and the government of Canada later settled out of court with Arar. He received C$10.5 million and Prime Minister Stephen Harper formally apologized to Arar for Canada's role in his "terrible ordeal."[7][8] Arar's story is frequently referred to as "extraordinary rendition" but the US government insisted it was a case of deportation.[14]

Hopefully, given that little intuition pump, you can also imagine that he could have died from the torture instead of ever returning home.
