Right now, under both section 7 of the charter and under international law, particularly article 3 of the UN Convention Against Torture, there is a bar on deporting someone to persecution or torture. The Supreme Court, in the case of Suresh, and many international tribunals and other Supreme Court cases, has repeatedly said that Canada cannot deport someone to a risk of torture.
The PRRA exists for that one last review, to make sure that Canada doesn't make a mistake and deport someone to persecution and torture. If we limit this access, Canada will be deporting people. Of course, it's a tiny number.
One of the proposals we have made is to dump the current PRRA process. As you say, it's a tiny percentage that are accepted. Switch it into.... If we're going to have an IRB and a RAD that are truly expert, independent decision-makers, give them full authority for making risk assessments and allow people to reopen their claim if they can establish that there's new evidence or a change in circumstances during that one year.
