That's right.
Before the agreement came into effect, a third of all asylum seekers came from the United States. Since the agreement came into effect, it only applies to people who show up at official checkpoints in Canada and the United States, and not to those who cross the border in an irregular manner. if an individual shows up at an official checkpoint, they can be told to return to the United States, because it is a safe country.
What we are trying to address now is the Roxham Road issue, because it's beyond the scope of the current agreement.
