It's not for UNHCR to comment on the particular mode that Canada wishes to use for controlling its border. It's an independent sovereign state. As long as the process upholds their international legal obligations, that is our primary concern.
As I said, on my visits to Roxham Road, which are fairly regular, those that I make and that my colleagues make, what we have observed is that notwithstanding the fact that we are using an irregular entry point, the process is handled with a significant degree of care and it is meeting the minimum legal requirements.
