As part of the passing of Bill C-31 in December 2012, asylum seekers arriving at a point of entry on the Canadian border have been subject to incarceration and detention. Claimants are subject to detention for failing to provide sufficient identification documents, which is in violation with the United Nations Refugee Convention, to which Canada is a signatory. In 2010–2011, Canada detained 8,838 people, of which 4,151 of them were asylum seekers or rejected refugee claimants. There is a requirement to the maximum time limit spent in detention upon being released, a situation which has been subject to criticism held in contrast to areas in Europe: Ireland (30 days), France (32 days), Spain (40 days), and Italy (60 days).
