In terms of how that might affect Canada, right now, there are very few people from NTCA countries arriving in Canada, and that's because it's difficult to make it into the U.S., and difficult to make it through the U.S. Where it might start impacting Canada—and that's something that people, the current government especially, needs to keep on their radar—is when the U.S. will end temporary protected status for people from the region, which will coincide almost directly with the next federal election in Canada.
When the Trump government announced it was ending TPS for Haitians, roughly 10% from the U.S. decided to come to Canada. If the same number of people from El Salvador and Guatemala who have TPS now in the U.S. did that, it would double the asylum claims in Canada overnight, or in very short order, which is something that we should keep in mind.
