A new federal study questions the millions of dollars spent on locking up many immigrants and refugee claimants, prompting the government to seek alternatives, the Globe and Mail reported. According to the internal evaluation report, the Canada Border Service Agency spent more than $45 million detaining people in 2008-09. As a result, the government is studying lower-cost alternatives, including a Toronto bail program. The border agency is to develop a "national detentions strategy" by September, according to the report. High-risk detainees are usually held in provincial jails, its use being on the rise.
