Ottawa, Canada (CNN) -- Guantanamo detainee Omar Khadr has been transferred to his homeland of Canada to serve the remainder of his sentence, Canada's Public Safety Minister Vic Toews said Saturday. Khadr boarded a military plane at the Guantanamo Naval base in Cuba and arrived at a military airbase in Trenton, Ontario. He will serve the rest of his sentence at Millhaven Prison in Bath, Ontario, about 130 miles east of Toronto. The case and the prisoner's legal fate have sparked controversy among Canadians. Many think his sentence has been too lenient. Others, noting his capture at age 15, think he should have been treated as a child soldier and point to alleged mistreatment while in custody.
