The exempted groups are convention refugees, such as resettled refugees. They are protected persons, people found to be refugees in Canada. Then there are some members of the family class, the close family members. If I were sponsoring my spouse and my dependent children, they would be exempt from the medical inadmissibility provisions. We still do immigration medical exams because we want to know from a public health or public safety perspective whether there's something that we need to be concerned about.
Then there are folks who are not exempted. The kinds of cases you're talking about tend to be economic immigrants, and it's either the principal applicant or one of the dependants of that economic immigrant who has issues, who has a health condition that then raises concerns around excessive demand. It might be a live-in caregiver. It might be a federal skilled worker. It might be a student.
