Chelsea Manning says she has been "permanently banned" from entering Canada because of her criminal record.
Manning, a former U.S. Army intelligence analyst, tweeted about the issue Monday. She was released from a military prison in May after serving seven years for leaking thousands of classified military documents.
Manning shared a photo of what appears to be a letter from Canadian immigration officials. A spokesperson for Immigration Minister Ahmed Hussen told HuffPost Canada by email he would not comment on the case, citing privacy laws.
The document shows Manning, 29, was denied entry to Canada Friday at the border crossing in St-Bernard-de-Lacolle, Que.
The report cites a provision from the Immigration and Refugee Protection Act on "serious criminality," stating a person is inadmissible if they have been convicted of an offence outside of Canada that, if committed in this country, would be "punishable by a maximum term of imprisonment of at least 10 years."
The document states Manning's violation of the United States Espionage Act would equate to treason in Canada, punishable with a "maximum penalty of 14 years imprisonment."
Manning tweeted she would challenge the denial of entry at a future admissibility hearing.
