Canada's Alcatraz closing its doors today
Canada's most notorious prison, dubbed by some as Canada's Alcatraz, formally shuts its doors today.
Federal officials say the prison, which opened in June 1835, is outdated and too expensive to maintain.
The Lake Ontario-side ``pen'' has housed some of the worst criminals Canada has produced, including Clifford Olson and Paul Bernardo,
What happens next to the facility, designated a national historic site in 1990, is uncertain.
Some have suggested it be turned into a tourist attraction.
