Vic Toews said Saturday that 26-year-old Omar Khadr arrived at a military base on a U.S. government plane early Saturday and has been transferred to Millhaven maximum security prison in Bath, Ontario.

Khadr pleaded guilty in 2010 to killing a U.S. soldier in Afghanistan and was eligible to return to Canada from Guantanamo Bay last October under terms of a plea deal.

Khadr was 15 when he was captured in 2002 in Afghanistan, and has spent a decade at Guantanamo, the U.S. naval base in Cuba. He received an eight-year sentence in 2010.

Khadr was convicted of throwing a grenade that killed Army Sgt. 1st Class Christopher Speer during a 2002 firefight.
