The security certificate law, used to arrest and deport non-Canadians considered threats to national security, has become controversial in recent years because it relies on evidence heard in secret, and detainees are not informed in full detail of the allegations against them. Earlier in December, it was reported that the Canadian government has begun reviewing [JURIST report] its security certificate system. Public Safety Minister Peter Van Loan [official profile] said the government is considering making significant changes to the law or abolishing it completely. In September, the government withdrew [National Post report] a certificate against Moroccan-born Montreal resident Adil Charkaoui in lieu of subjecting its evidence against him to review in court. Charkaoui is also suing the government.
