Under Bill C-4, for a very specific group of individuals who arrive, could be in detention for up to a year or until their refugee claim is determined by the IRB, whichever is sooner. Under the bill that has been released today, the expectation is that a refugee determination will be made very quickly, within a matter of I think 40 days for designated country of origins. So the new system will work to ensure that people are not in detention unnecessarily.
