It depends on the situation. If you applied inland, you 100% won't get any of your documents back.
If you applied outland, not all VO return your documents. Some VOs do return the originals, however I do believe your medical file will not be returned since the medical results was likely submitted electronically. How can you get your medical information back from CIC electronically. Your local clinic would probably have your medical record on file. You would have to ask them to give you a copy of your medical record. Everything else can be returned at VO's discretion.
