If the issue is the information with respect to changed country conditions, that information would be submitted by the applicant to the Immigration and Refugee Board. If the member of Parliament has information that would be pertinent to the individual's case, then as long as he or she ensures that the person is aware, the person can make those submissions in their application to the Immigration and Refugee Board. If you're looking at a suspension or a stay or deferral of removal, you will still be able to ask the Canada Border Services Agency to intervene in that way.
