The federal government says it plans to appeal a court ruling that orders Omar Khadr be transferred to a provincial jail.
The Alberta Court of Appeal has ruled the former Guantanamo Bay detainee should be serving a youth sentence in Canada and not be in a federal prison.
In a statement, Public Safety Minister Steven Blaney says a youth sentence is not appropriate for Khadr.
He says the government will be seeking a stay of the appeal decision while it asks the Supreme Court to hear the case.
Khadr pleaded guilty in 2010 to several war-crimes charges, including murder, for killing an American soldier in Afghanistan when he was 15.
After spending a decade in Guantanamo Bay, Khadr was sentenced by a U.S. military commission to an additional eight years and sent to Canada.
