Yes, certainly. All admissibilities at port of entry need to be referred to the Immigration and Refugee Board for consideration in front of the immigration division. Consideration of that file can also be judicially reviewed by the Federal Court. Decisions made, taken in the visa context overseas, similarly have access to judicial review, but not in the same scope that's supported at the Federal Court when a person is in Canada and confronted with allegations of inadmissibility.
