I'll start off, and then perhaps other colleagues will want to jump in as per their mandates and their ministers' mandates.
In the simplest terms, there are two conventions that guide how Canada has created and operationalizes its asylum protection system. There are some fundamental principles within those conventions. We have due processes and a system in place in place that allow individuals to claim asylum, not be turned back, without risk of refoulement, and also to allow people to explain, before the country they're availing themselves of, why they're in need of protection or are in fear of persecution.
When it comes to an individual's border—and I'll ask Mr. Cloutier to speak more on that—we are living up to our international obligations, our humanitarian traditions, and our role in protecting people who are seeking protection. The concept of simply turning back someone from your border also has to include a very stiff assessment of where you are turning them back to, and if you are complicit in making that person's life worse off by turning them back at a border, especially when they're asking for your help. That's called claiming asylum.
