I will address a part of that question and I will let my colleague complement as well.
First, I have just a small correction in terms of 50% of those people actually being returned once a determination is done: 61% of irregular arrivals are accepted as refugees in Canada currently. That's quite a high statistic in terms of understanding that these people have merits in their claim.
Then the ones who do not get accepted have to go through an appeal process. From the irregular arrivals that do go through an appeal process on the merits of their claim, a third of them are either accepted as refugees or returned for another refugee hearing because there was a problem in the process before.
If all of the appeal process has been exhausted, then UNHCR recommends states to return people to their countries of origin to maintain the integrity of the asylum system.
I will let my colleague address a few other parts of your question.
I'm sorry. I'm going to have to ask you to repeat which parts you wanted answered.
