You're right about the construct, that some claimants are successful and then, once they're successful at the Immigration and Refugee Board, they become protected persons and would be eligible for social benefits were a province to impose a residency requirement that otherwise limited that. By contrast, some claimants are found to have unfounded claims. If they have unfounded claims, then they would be subject to a removal order. If a province had brought in a residency requirement, they wouldn't be receiving benefits up to the point of that determination.
